Abstract

This book is targeted at MantisBT developers, contributors and plugin authors. It documents the development process and provides reference information regarding the MantisBT core, including the database schema as well as the plugin system including an events reference.

# ⁠Chapter 1. Contributing to MantisBT

MantisBT source code is managed with Git. If you are new to this version control system, you can find some good resources for learning and installing it in Section 8.1, “Git References”.

## ⁠1.1. Initial Setup

There are a few steps the MantisBT team requires of contributors and developers when accepting code submissions. The user needs to configure Git to know their full name (not a screen name) and an email address they can be contacted at (not a throwaway address).
To set up your name and email address with Git, run the following commands, substituting your own real name and email address:

    git config --global user.name "John Smith"
    git config --global user.email "jsmith@mantisbt.org"

Optionally, you may want to configure Git to use terminal colors when displaying file diffs and other information, and also alias certain Git actions to shorter phrases to reduce typing:

    git config --global color.diff "auto"
    git config --global color.status "auto"
    git config --global color.branch "auto"

    git config --global alias.st "status"
    git config --global alias.di "diff"
    git config --global alias.co "checkout"
    git config --global alias.ci "commit"

## ⁠1.2. Cloning the Repository

The official MantisBT source code repository is hosted at GitHub. This document assumes that you have already signed up for and setup a GitHub account.

### ⁠1.2.1. Determining the Clone URL

Which URL you will use to clone the repository before you start developing depends on your situation.

MantisBT Core Team Developers
  MantisBT developers have push access to the official repository.
  Benefiting from this access requires a special URL that uses your SSH key to handle access permissions: `git@github.com:mantisbt/mantisbt.git`. Alternatively, an HTTPS link can be used as well, in which case you will have to provide your GitHub User ID and password when Git requests it: https://github.com/mantisbt/mantisbt.git.

  Note

  Pushes will fail if you do not have access or your public SSH key is not set up correctly in your GitHub profile.
Contributors
  For other people, the MantisBT repository and the related clone URLs `git@github.com:mantisbt/mantisbt.git` (SSH). or https://github.com/mantisbt/mantisbt.git (HTTPS) will always be read-only.
  It is therefore strongly advised to create your own fork of MantisBT where you will be able to push your changes, and then use the fork's URL instead to clone, which will look like this: `git@github.com:MyGithubId/mantisbt.git`. or https://github.com/MyGithubId/mantisbt.git

### ⁠1.2.2. Initializing the Clone

To clone the repository, execute the following command from your target workspace:

    git clone YourCloneURL

After performing the cloning operation, you should end up with a new directory in your workspace, `mantisbt/`, containing the MantisBT repository with a `remote` named origin pointing to your Clone URL.
MantisBT uses Composer to pull libraries and components from Packagist and Github. Install Composer and run the following command:

    composer install

Warning

Failure to execute the submodule initialization commands will result in critical components being missing from `/vendor` folder, which will then cause errors when running MantisBT.

### ⁠1.2.3. Adding remotes

If you are planning to use your own fork to push and maintain your changes, then we recommend setting up an upstream `remote` for MantisBT's official repository, which will make it easier to keep your repository up-to-date.

    git remote add --tags upstream git://github.com/mantisbt/mantisbt.git

### ⁠1.2.4. Checking out branches

By default, the new clone will only track code from the primary remote branch, `master`, which is the latest development version of MantisBT. If you are planning to work with stable release or other development branches, you will need to set up local tracking branches in your repository.
The following command will set up a tracking branch for the current stable branch, `master-1.3.x`.

    git checkout -b master-1.3.x origin/master-1.3.x

Note

With the introduction of submodules for some of the third-party libraries, you may encounter issues when switching to an older branch which still has code from those libraries in a subdirectory of `/library` rather than a submodule:

    $ git checkout old_branch
    error: The following untracked working tree files would be overwritten by checkout
    	(list of files)
    Aborting

To resolve this, you first have to get rid of the submodules directories before you can checkout the branch. The command below will move all submodules to `/tmp`:

    sed -rn "s/^.*path\s*=\s*(.*)$/\1/p" .gitmodules |xargs -I{} mv -v {} /tmp
    git checkout old_branch

Alernatively, if you don't care about keeping the changes in the submodules directories, you can simply execute

    git checkout -f old_branch
    git clean -df

When switching back from the older branch, the submodules directories will be empty. At that point you can either

- Update the submodules to reclone them

      git submodule update

- Restore the directories previously moved to `/tmp` back into the empty directories, e.g.

      sed -rn "s/^.*path\s*=\s*(.*)$/\1/p" .gitmodules |xargs -n 1 basename |xargs -I{} mv -v /tmp/{} library

## ⁠1.3. Maintaining Tracking Branches

In order to keep your local repository up-to-date with the official one, there are a few simple commands needed for any tracking branches that you may have, including `master` and `master-1.3.x`.
First, you'll need to get the latest information from the remote repository:

    git fetch origin

Note

If you cloned from your personal GitHub fork instead of the official MantisBT repository as explained in Section 1.2.3, “Adding remotes”, then you should instead execute:

    git fetch upstream

Then for each tracking branch you have, enter the following commands:

    git checkout BranchName
    git rebase

Alternatively, you may combine the fetch and rebase operations described above into a single pull command (for each remote tracking branch):

    git checkout master
    git pull --rebase

## ⁠1.4. Preparing Feature Branches

For each local or shared feature branch that you are working on, you will need to keep it up to date with the appropriate master branch. There are multiple methods for doing this, each better suited to a different type of feature branch. Both methods assume that you have already performed the previous step, to update your local tracking branches (see Section 1.3, “Maintaining Tracking Branches”).

### ⁠1.4.1. Private Branches

If the topic branch in question is a local, private branch, that you are not sharing with other developers, the simplest and easiest method to stay up to date with `master` is to use the `rebase` command. This will append all of your feature branch commits into a linear history after the last commit on the `master` branch.

    git rebase master feature

Note

Rebasing changes the ID for each commit in your feature branch, which will cause trouble for anyone sharing and/or following your branch.
The resulting conflict can be fixed by rebasing their copy of your branch onto your branch:

    git checkout feature
    git fetch remote/feature
    git rebase remote/feature

### ⁠1.4.2. Public Branches

For any publicly-shared branches, where other users may be watching your feature branches, or cloning them locally for development work, you'll need to take a different approach to keeping it up to date with `master`.
To bring public branch up to date, you'll need to `merge` the current `master` branch, which will create a special "merge commit" in the branch history, causing a logical "split" in commit history where your branch started and joining at the merge. These merge commits are generally disliked, because they can crowd commit history, and because the history is no longer linear. They will be dealt with during the submission process (see Section 1.5, “Running PHPUnit tests”).

    git checkout feature
    git merge master

At this point, you can push the branch to your public repository, and anyone following the branch can then pull the changes directly into their local branch, either with another merge, or with a rebase, as necessitated by the public or private status of their own changes.

## ⁠1.5. Running PHPUnit tests

MantisBT has a suite of PHPUnit tests found in the `tests` directory. You are encouraged to add your own tests for the patches you are submitting, but please remember that your changes must not break existing tests.
In order to run the tests, you will need to have the PHP Soap extension, PHPUnit 3.4 or newer and Phing 2.4 or newer installed. The tests are configured using a `bootstrap.php` file. The `boostrap.php.sample` file contains the settings you will need to adjust to run all the tests.
Running the unit tests is done from root directory using the following command:

    phing test

### ⁠1.5.1. Running the SOAP tests

MantisBT ships with a suite of SOAP tests which require an initial set up to be executed. The required steps are:

- Install MantisBT locally and configure a project and a category.
- Adjust the `bootstrap.php` file to point to your local installation.
- Customize the `config_inc.php` to enable all the features tested using the SOAP tests. The simplest way to do that is to run all the tests once and adjust it based on the skipped tests.

## ⁠1.6. Submitting Changes

This section describes what you should do to submit a set of changes to MantisBT, allowing the project developers to review and test, your code, and ultimately commit it to the MantisBT repository.
The actual submission can be done using several methods, described later in this section:

- Recommended: Github Pull Requests (see Section 1.6.2, “Submission Via Github Pull Requests”)
- Other public Git repository Pull Requests (see Section 1.6.4, “Submission Via Public Repository”)
- Git Formatted patches (see Section 1.6.3, “Submission Via Formatted Patches”)

### ⁠1.6.1. Before you submit

Before submitting your contribution, you should make sure that

1. Your code follows the MantisBT coding guidelines
2. You have tested your changes locally (see Section 1.5, “Running PHPUnit tests”)
3. Your local branch has been rebased on top of the current Master branch, as described in Section 1.4.1, “Private Branches”.

### ⁠1.6.2. Submission Via Github Pull Requests

Since the official MantisBT repository is hosted there, using GitHub is the recommended (and easiest) way to submit your contributions.
With this method, you can keep your changesets up-to-date with the official development repository, and likewise let anyone stay up to date with your repository, without needing to constantly upload and download new formatted patches whenever you change anything.
The process below describes a simple workflow that can help you make your submission if you are not familiar with Git; note that it is by no means the only way to do this.

Note

We'll assume that you have already forked MantisBT, cloned it locally as described in Section 1.2, “Cloning the Repository” (remote upstream being the official MantisBT repository and origin your personal fork), and created a new feature branch (see Section 1.4, “Preparing Feature Branches”) for your contribution, which we'll call MyBranch.

1. Make sure that the MyBranch feature branch is up-to-date with the master branch by rebasing it, resolving any conflicts if necessary.

       git fetch upstream
       git rebase upstream/master MyBranch

2. Push the branch to your Github fork

       git push origin MyBranch

3. Go to your Fork on Github (https://github.com/MyGithubId/mantisbt)
4. Initiate a Pull Request from your feature branch, following the guidelines provided in Github Help.
   Please make sure you provide a detailed description of the changes you are submitting, including the reason for it and if possible a reference (link) to an existing issue on our bugtracker. The team will usually review your changes and provide feedback within 7 days (but your mileage may vary).

### ⁠1.6.3. Submission Via Formatted Patches

Formatted patches are very similar to file diffs generated by other tools or source control systems, but contain far more information, including your name and email address, and for every commit in the set, the commit's timestamp, message, author, and more. They allow anyone to import the enclosed changesets directly into Git, where all of the commit information is preserved.
Assuming that you have an existing local that you've kept up to date with `master` as described in Section 1.4, “Preparing Feature Branches” currently checked out, generating a formatted patch set should be relatively straightforward, using an appropriate filename as the target of the patch set:

    git format-patch --binary --stdout origin/master..HEAD > feature_branch.patch

Once you've generated the formatted patch file, you can easily attach it to a bug report, or even use the patch file as an email to send to the developer mailing list. Developers, or other users, can then import this patch set into their local repositories using the following command, again substituting the appropriate filename:

    git am --signoff feature_branch.patch

### ⁠1.6.4. Submission Via Public Repository

If you are not able or not willing to make use of a fork of the official GitHub repository but have another publicly available one to host your changes, for example on a free hosting for public repository such as

- Bitbucket
- GitLab

you can still use it to submit a patch in a similar fashion to the Github method described above, although the process is slightly more complicated.
We'll assume you've already set up a publicly accessible repository at URL `git@githosting.com:contrib.git`, kept it up-to-date with MantisBT's official repository, and that you have pushed your feature branch `MyBranch` to it.

1. Generate the Pull Request
   This will list information about your changes and how to access them. The process will attempt to verify that you've pushed the correct data to the public repository, and will generate a summary of changes.

       git request-pull origin/master git@githosting.com:contrib.git MyBranch

2. Paste the output of the above command into a bug report or an email to the developer mailing list

Once your pull request has been posted, developers and other users can add your public repository as a remote, and track your feature branch in their own working repository using the following commands, replacing the remote name and local branch name as appropriate:

    git remote add feature  git@githosting.com:contrib.git
    git checkout -b MyBranch feature/MyBranch

If the feature is approved for entry into MantisBT core, then the branch should first be rebased onto the latest HEAD so that Git can remove any unnecessary merge commits, and create a linear history. Once that's completed, the feature branch can be merged into `master`:

    git rebase master feature
    git checkout master
    git merge --no-ff feature

# ⁠Chapter 2. Database Schema Management

## ⁠2.1. The MantisBT schema

The MantisBT database schema (excluding plugins) is described in the Entity-Relationship diagram (ERD) below. There is also a PDF version available for download.

## ⁠2.2. Schema Definition

TODO: Discuss the ADODB datadict formats and the format MantisBT expects for schema definitions.

## ⁠2.3. Installation / Upgrade Process

TODO: Discuss how MantisBT handles a database installation / upgrade, including the use of the config system and schema definitions.

# ⁠Chapter 3. Event System

## ⁠3.1. General Concepts

The event system in MantisBT uses the concept of signals and hooked events to drive dynamic actions. Functions, or plugin methods, can be hooked during runtime to various defined events, which can be signalled at any point to initiate execution of hooked functions.
Events are defined at runtime by name and event type (covered in the next section). Depending on the event type, signal parameters and return values from hooked functions will be handled in different ways to make certain types of common communication simplified.

## ⁠3.2. API Usage

This is a general overview of the event API. For more detailed analysis, you may reference the file `core/event_api.php` in the codebase.
⁠

> Declaring Events

> When declaring events, the only information needed is the event name and event type. Events can be declared alone using the form:

>     event_declare( $name, $type=EVENT_TYPE_DEFAULT );

> or they can be declared in groups using key/value pairs of name => type relations, stored in a single array, such as:

>     $events = array(
>     	$name_1 => $type_1,
>     	$name_2 => $type_2,
>     	...
>     	);

>     event_declare_many( $events );

⁠

> Hooking Events

> Hooking events requires knowing the name of an already-declared event, and the name of the callback function (and possibly associated plugin) that will be hooked to the event. If hooking only a function, it must be declared in the global namespace.

>     event_hook( $event_name, $callback, [$plugin] );

> In order to hook many functions at once, using key/value pairs of name => callback relations, in a single array:

>     $events = array(
>     	$event_1 => $callback_1,
>     	$event_2 => $callback_2,
>     	...
>     	);

>     event_hook( $events, [$plugin] );

⁠

> Signalling Events

> When signalling events, the event type of the target event must be kept in mind when handling event parameters and return values. The general format for signalling an event uses the following structure:

>     $value = event_signal( $event_name, [ array( $param, ... ), [ array( $static_param, ... ) ] ] );

> Each type of event (and individual events themselves) will use different combinations of parameters and return values, so perusing Chapter 5, Events Reference is recommended for determining the unique needs of each event when signalling and hooking them.

## ⁠3.3. Event Types

There are five standard event types currently defined in MantisBT. Each type is a generalization of a certain "class" of solution to the problems that the event system is designed to solve. Each type allows for simplifying a different set of communication needs between event signals and hooked callback functions.
Each type of event (and individual events themselves) will use different combinations of parameters and return values, so perusing Chapter 5, Events Reference is recommended for determining the unique needs of each event when signalling and hooking them.
⁠

> EVENT_TYPE_EXECUTE

> This is the simplest event type, meant for initiating basic hook execution without needing to communicate more than a set of immutable parameters to the event, and expecting no return of data.
> These events only use the first parameter array, and return values from hooked functions are ignored. Example usage:

>     event_signal( $event_name, [ array( $param, ... ) ] );

⁠

> EVENT_TYPE_OUTPUT

> This event type allows for simple output and execution from hooked events. A single set of immutable parameters are sent to each callback, and the return value is inlined as output. This event is generally used for an event with a specific purpose of adding content or markup to the page.
> These events only use the first parameter array, and return values from hooked functions are immediately sent to the output buffer via 'echo'. Another parameter `$format` can be used to model how the results are printed. This parameter can be either:
> - null, or omitted: The returned values are printed without further processing
> - <String>: A string to be used as separator for printed values
> - <Array>: An array of (prefix, separator, postfix) to be used for the printed values
> Example usage:

>     event_signal( $event_name, [ array( $param, ... ) ], [ $format ] );

⁠

> EVENT_TYPE_CHAIN

> This event type is designed to allow plugins to successively alter the parameters given to them, such that the end result returned to the caller is a mutated version of the original parameters. This is very useful for such things as output markup parsers.
> The first set of parameters to the event are sent to the first hooked callback, which is then expected to alter the parameters and return the new values, which are then sent to the next callback to modify, and this continues for all callbacks. The return value from the last callback is then returned to the event signaller.
> This type allows events to optionally make use of the second parameter set, which are sent to every callback in the series, but should not be returned by each callback. This allows the signalling function to send extra, immutable information to every callback in the chain. Example usage:

>     $value = event_signal( $event_name, $param, [ array( $static_param, ... ) ] );

⁠

> EVENT_TYPE_FIRST

> The design of this event type allows for multiple hooked callbacks to 'compete' for the event signal, based on priority and execution order. The first callback that can satisfy the needs of the signal is the last callback executed for the event, and its return value is the only one sent to the event caller. This is very useful for topics like user authentication.
> These events only use the first parameter array, and the first non-null return value from a hook function is returned to the caller. Subsequent callbacks are never executed. Example usage:

>     $value = event_signal( $event_name, [ array( $param, ... ) ] );

⁠

> EVENT_TYPE_DEFAULT

> This is the fallback event type, in which the return values from all hooked callbacks are stored in a special array structure. This allows the event caller to gather data separately from all events.
> These events only use the first parameter array, and return values from hooked functions are returned in a multi-dimensional array keyed by plugin name and hooked function name. Example usage:

>     $values = event_signal( $event_name, [ array( $param, ... ) ] );

# ⁠Chapter 4. Plugin System

## ⁠4.1. General Concepts

The plugin system for MantisBT is designed as a lightweight extension to the standard MantisBT API, allowing for simple and flexible addition of new features and customization of core operations. It takes advantage of the new Event System (see Chapter 3, Event System) to offer developers rapid creation and testing of extensions, without the need to modify core files.
Plugins are defined as implementations, or subclasses, of the `MantisPlugin` class as defined in `core/classes/MantisPlugin.php`. Each plugin may define information about itself, as well as a list of conflicts and dependencies upon other plugins. There are many methods defined in the `MantisPlugin` class that may be used as convenient places to define extra behaviors, such as configuration options, event declarations, event hooks, errors, and database schemas. Outside a plugin's core class, there is a standard method of handling language strings, content pages, and files.
At page load, the core MantisBT API will find and process any conforming plugins. Plugins will be checked for minimal information, such as its name, version, and dependencies. Plugins that meet requirements will then be initialized. At this point, MantisBT will interact with the plugins when appropriate.
The plugin system includes a special set of API functions that provide convenience wrappers around the more useful MantisBT API calls, including configuration, language strings, and link generation. This API allows plugins to use core API's in "sandboxed" fashions to aid interoperation with other plugins, and simplification of common functionality.

## ⁠4.2. Building a Plugin

This section will act as a tutorial to build a new plugin, from the bare basics all the way up to advanced topics.
A general understanding of HTML, PHP and the concepts covered in the last section is assumed, as well as knowledge of how the event system works. Later topics in this section will require knowledge of database schemas and how they are used with MantisBT.
This walk-through will be working towards building a single end result: the Example Plugin. You may refer to the final code along the way (see Section 4.2.8, “Example Plugin source code”), although every part of it will be built up in steps throughout this section.

### ⁠4.2.1. Plugin Structure

This section will introduce the general concepts of plugin structure, and how to get a bare-bones plugin working with MantisBT. Not much will be mentioned yet on the topic of adding functionality to plugins, just how to get the development process rolling.
The backbone of every plugin is what MantisBT calls the basename, a succinct, and most importantly, unique name that identifies the plugin. It may not contain any spacing or special characters beyond the ASCII upper- and lowercase alphabet, numerals, and underscore. This is used to identify the plugin everywhere except for what the end-user sees. For our "Example" plugin, the basename we will use should be obvious enough: `Example`.
Every plugin must be contained in a single directory, named to match the plugin's basename, as well as contain at least a single PHP file, also named to match the basename, as such:
Note that for plugins that require a database schema to operate, the basename is also used to build the table names, using the MantisBT table prefixes and suffix (please refer to the Admin Guide's Configuration section for further information). If our Example plugin were to create a table named 'foo', assuming default values for prefixes and suffix in MantisBT configuration, the physical table name would be `mantis_plugin_Example_foo_table`.

    Example/
    	Example.php

Warning

Depending on case sensitivity of the underlying file system, these names must exactly match the plugin's base name, i.e. `example` will not work.
This top-level PHP file must then contain a concrete class deriving from the `MantisPlugin` class, which must be named in the form of `%Basename%Plugin`, which for our purpose becomes `ExamplePlugin`.
Because of how `MantisPlugin` declares the `register()` method as `abstract`, our plugin must implement that method before PHP will find it semantically valid. This method is meant for one simple purpose, and should never be used for any other task: setting the plugin's information properties including the plugin's name, description, version, and more. Please refer to Section 4.2.2, “Properties” below for details about available properties.
Once your plugin defines its class, implements the `register()` method, and sets at least the name and version properties, it is then considered a "complete" plugin, and can be loaded and installed within MantisBT's plugin manager. At this stage, our Example plugin, with all the possible plugin properties set at registration, looks like this:

    Example/Example.php

    <?php
    class ExamplePlugin extends MantisPlugin {
        function register() {
            $this->name = 'Example Plugin';      # Proper name of plugin
            $this->description = 'Example Plugin from MantisBT Developers Guide';
                                                 # Short description of the plugin
            $this->page = '';                    # Default plugin page

            $this->version = '2.0';              # Plugin version string
            $this->requires = array(             # Plugin dependencies
                'MantisCore' => '2.0',           # Should always depend on an appropriate
                                                 # version of MantisBT
            );

            $this->author = 'MantisBT Team';     # Author/team name
            $this->contact = 'mantisbt-dev@lists.sourceforge.net';
                                                 # Author/team e-mail address
            $this->url = 'https://mantisbt.org'; # Support webpage
        }
    }

This alone will allow our Example plugin to be installed with MantisBT, and is the foundation of any plugin. More of the plugin development process will be continued in the next sections.

### ⁠4.2.2. Properties

This section describes the properties that can be defined when registering the plugin.

name
  Your plugin's full name. Required value.
description
  A full description of your plugin.
page
  The name of a plugin page for further information and administration of the plugin; this is usually the Plugin's configuration page. MantisBT will create a link to the specified page on the Manage Plugins page.
version
  Your plugin's version string. Required value. We recommend following the Semantic Versioning specification, but you are free to use any versioning scheme that can be handled by PHP's version_compare() function.
requires
  An array of key/value pairs of basename/version plugin dependencies.

  Note

  The special, reserved `MantisCore` basename can be used to specify the minimum requirement for MantisBT core.
  The version string can be defined as:
  - Minimum requirement: the plugin specified by the given basename must be installed, and its version must be equal or higher than the indicated one.
  - Maximum requirement: prefixing a version number with '`<`' will allow the plugin to specify the highest version (non-inclusive) up to which the required dependency is supported.

    Note

    If the plugin's minimum dependency for MantisCore is unspecified or lower than the current release (i.e. it does not specifically list the current core version as supported) and the plugin does not define a maximum dependency, a default one will be set to the next major release of MantisBT. (i.e. for 2.x.y we would add `'<2`').
    This effectively disables plugins which have not been specifically designed for a new major Mantis release, thus forcing authors to review their code, adapt it if necessary, and release a new version of the plugin with updated dependencies.
  - Both minimum and maximum: the two version numbers must be separated by a comma.
  Here are a few examples to illustrate the above explanations, assuming that the current Mantis release (MantisCore version) is 2.1:
  - Old release without a maximum version specified

        $this->requires = array( 'MantisCore' => '1.3.1' );

    The plugin is compatible with MantisBT >= 1.3.1 and < 2.0.0 - note that the maximum version (`<2`) was added by the system.
  - Current release without a maximum version specified

        $this->requires = array( 'MantisCore' => '2.0' );

    The plugin is compatible with MantisBT >= 2.0 and < 3.0 (the latter is implicit); code supporting older releases (e.g. 1.3) must be maintained separately (i.e. in a different branch).
  - Only specify a maximum version

        $this->requires = array( 'MantisCore' => '< 3.1' );

    The plugin is compatible up to MantisBT 3.1 (not inclusive).
  - Old release with a maximum version

        $this->requires = array( 'MantisCore' => '1.3, < 4.0' );

    The plugin is compatible with MantisBT >= 1.3 and < 4.0.
uses
  An array of key/value pairs of basename/version optional (soft) plugin dependencies. See `requires` above for details on how to specify versions.
author
  Your name, or an array of names.
contact

### ⁠4.2.3. Pages and Files

The plugin API provides a standard hierarchy and process for adding new pages and files to your plugin. For strict definitions, pages are PHP files that will be executed within the MantisBT core system, while files are defined as a separate set of raw data that will be passed to the client's browser exactly as it appears in the filesystem.
Your Plugin's pages must:

- be placed in the `pages/` directory,
- be named using only letters, numbers and underscores, and
- have a `.php` file extension

To generate a URI to a page in MantisBT, the API function `plugin_page()` should be used. Our Example plugin will create a page named `foo.php`, which can then be accessed via `plugin_page.php?page=Example/foo`:

    Example/pages/foo.php

    <?php
    layout_page_header();
    layout_page_begin();
    ?>

    <p>
        Here is a link to <a href="<?php echo plugin_page( 'foo' ) ?>">page foo</a>.
    </p>

    <?php
    layout_page_end();

Note

The calls to `layout_page_begin()` and `layout_page_end()` trigger the standard MantisBT header and footer portions, respectively, which also displays things such as the menus and triggers other layout-related events. `layout_page_header()` pulls in the CSS classes for alternating row colors in the table, amongst other things.
Adding non-PHP files, such as images or CSS stylesheets, follows a very similar pattern as pages. Files should be placed in the plugin's `files/` directory, and can only contain a single period in the name. The file's URI is generated with the `plugin_file()` function.
For our Example plugin, we'll create a basic CSS stylesheet, and modify the previously shown page to include the stylesheet:

    Example/files/foo.css

    p.foo {
        color: red;
    }

    Example/pages/foo.php
    ...

    <link rel="stylesheet" type="text/css" href="<?php echo plugin_file( 'foo.css' ) ?>" />
    <p class="foo">
        Our custom stylesheet paints this text red.
    </p>

Note

While `plugin_page()` expects only the page's name without the extension, `plugin_file()` on the other hand requires the entire filename, so that it can distinguish e.g. between `foo.css` and a potential image file called `foo.png`.
The plugin's filesystem structure at this point looks like this:

    Example/
    	Example.php
    	pages/
    		foo.php
    	files/
    		foo.css

### ⁠4.2.4. Events

Plugins have an integrated method for both declaring and hooking events, without needing to directly call the event API functions. These take the form of class methods on your plugin.
To declare a new event, or a set of events that your plugin will trigger, override the `events()` method of your plugin class, and return an associative array with event names as the key, and the event type as the value.
Let's add to our Example plugin, a new event foo that does not expect a return value (an "execute" event type), and another event bar expecting a single value that gets modified by each hooked function (a "chain" event type):

    Example/Example.php

    <?php
    class ExamplePlugin extends MantisPlugin {
        ...

        function events() {
            return array(
                'EVENT_EXAMPLE_FOO' => EVENT_TYPE_EXECUTE,
                'EVENT_EXAMPLE_BAR' => EVENT_TYPE_CHAIN,
            );
        }
    }

When the Example plugin is loaded, the event system in MantisBT will add these two items to its list of events, and will then allow other plugins or functions to hook them.

Note

Naming the events "EVENT_PLUGINBASENAME_EVENTNAME" is not required, but is considered best practice to avoid conflicts between plugins.
Hooking events, whether they are your own plugin's or defined elsewhere, is almost identical to declaring them. Instead of passing an event type as the value, your plugin must give the name of a class method that will be called when the event is triggered.
For our Example plugin, we'll create a `foo()` and a `bar()` methods in our plugin class, then hook them to the events we declared earlier. We'll also hook the standard `EVENT_MENU_MAIN` event, to link the custom page we created in Section 4.2.3, “Pages and Files”.

    Example/Example.php

    <?php
    class ExamplePlugin extends MantisPlugin {
        ...

        function hooks() {
            return array(
                'EVENT_MENU_MAIN' => 'menu',

                'EVENT_EXAMPLE_FOO' => 'foo',
                'EVENT_EXAMPLE_BAR' => 'bar',
            );
        }
    }

Function signatures vary depending on the hooked event's type (see Section 3.3, “Event Types”). They generally should accept the `$p_event` parameter, which contains the event name triggering the method (allowing a single method to respond to multiple events). The `bar()` method also accepts and returns a second parameter, in order to match the expectations of chained events.
Now that we have our plugin's events declared and hooked, let's define the hook methods and modify our earlier page so it triggers the new events:

    Example/Example.php

    <?php
    class ExamplePlugin extends MantisPlugin {
        ...
        function menu() {
            $t_menu[] = array(
                'title' => $this->name,
                'url' => plugin_page( 'foo' ),
                'access_level' => ANYBODY,
                'icon' => 'fa-smile-o'
            );
            return $t_menu;
        }

        function foo( $p_event ) {
            echo 'In method foo(). ';
        }

        function bar( $p_event, $p_chained_param ) {
            return str_replace( 'foo', 'bar', $p_chained_param );
        }
    }

    Example/pages/foo.php
    ...

    <p>
        Custom event hooks:
    <?php
    event_signal( 'EVENT_EXAMPLE_FOO' );

    $t_string = 'A sentence with the word "foo" in it.';
    $t_new_string = event_signal( 'EVENT_EXAMPLE_BAR', array( $t_string ) );
    echo $t_new_string;
    ?>
    </p>

When the first event "foo" is signaled, the Example plugin's `foo()` method will execute and echo a string. After that, the second event "bar" is signaled, and the page passes a string parameter; the plugin's `bar()` gets the string and replaces any instance of "foo" with "bar", and returns the resulting string. If any other plugin had hooked the event, that plugin could have further modified the new string from the Example plugin, or vice versa, depending on the loading order of plugins. The page then echos the modified string that was returned from the event.

### ⁠4.2.5. Configuration

Similar to events, plugins have a simplified method for declaring configuration options, as well as API functions for retrieving or setting those values at runtime.
Declaring a new configuration option is achieved just like declaring events. By overriding the `config()` method on your plugin class, your plugin can return an associative array of configuration options, with the option name as the key, and the default option as the array value. Our Example plugin will declare an option "foo_or_bar", with a default value of "foo":

    Example/Example.php

    <?php
    class ExamplePlugin extends MantisPlugin {
        ...

        function config() {
            return array(
                'foo_or_bar' => 'foo',
            );
        }
    }

Retrieving the current value of a plugin's configuration option is achieved by using the plugin API's `plugin_config_get()` function, and can be set to a modified value in the database using `plugin_config_set()`. With these functions, the config option is prefixed with the plugin's name, in an attempt to automatically avoid conflicts in naming.
Our Example plugin will demonstrate this by adding a secure form to a new configuration page we'll call `config.php`, and handling the form on a separate `config_update.php` page that will modify the value in the database, and redirect back to the config page, just like any other form and action page in MantisBT:

Note

This code sample is a bare-bones implementation, focusing on functionality and meant for illustration purposes. Please refer to Section 4.2.7, “Layout” for a more realistic example, including layout and styling.

    Example/pages/config.php

    <?php
    $t_foo_or_bar = plugin_config_get( 'foo_or_bar' );
    ?>

    <form action="<?php echo plugin_page( 'config_update' )?>" method="post">
        <?php echo form_security_field( 'plugin_Example_config_update' ) ?>
        <label>
            Foo or Bar?
            <input name="foo_or_bar" value="<?php echo string_attribute( $t_foo_or_bar ) ?>" />
        </label>
        <br>
        <label>
            Reset
            <input type="checkbox" name="reset" />
        </label>
        <br>
        <input type="submit" />
    </form>

    Example/pages/config_update.php

    <?php
    form_security_validate( 'plugin_Example_config_update' );

    $f_foo_or_bar = gpc_get_string( 'foo_or_bar' );
    $f_reset = gpc_get_bool( 'reset', false );

    form_security_purge( 'plugin_Example_config_update' );

    if( $f_reset ) {
        plugin_config_delete( 'foo_or_bar' );
    } elseif( $f_foo_or_bar == 'foo' || $f_foo_or_bar == 'bar' ) {
        plugin_config_set( 'foo_or_bar', $f_foo_or_bar );
    } else {
        error_parameters( 'foo_or_bar', string_attribute( $f_foo_or_bar ) );
        trigger_error( ERROR_CONFIG_OPT_INVALID, ERROR );
    }

    print_successful_redirect( plugin_page( 'config', true ) );

Note

The `form_security_*()` functions are part of the Form API, and prevent CSRF attacks against forms that make changes to the system.
The last step is to add a link our new config page from the Manage Plugins page. This is as simple as referencing the config page's name in the `register()` method, which will turn the Plugin's name into an hyperlink.

    Example/Example.php

    	function register() {
    		...
    		$this->page = 'config';     # Default plugin page

### ⁠4.2.6. Language and Localization

MantisBT has a very advanced set of localization tools, which allow all parts of of the application to be localized to the user's preferred language. This feature has been extended for use by plugins as well, so that a plugin can be localized in much the same method as used for the core system. Localizing a plugin involves creating a language file for each localization available, and using a special API call to retrieve the appropriate string for the user's language.
All language files for plugins follow the same format used in the core of MantisBT, should be placed in the plugin's `lang/` directory, and named the same as the core language files. Strings specific to the plugin should be "namespaced" in a way that will minimize any risk of collision. Translating the plugin to other languages already supported by MantisBT is then as simple as creating a new strings file with the localized content; the MantisBT core will find and use the new language strings automatically.
We'll use the pages from the previous examples, and dress them up with localized language strings. First we need to create a language file for English, MantisBT's default language which is also used as fallback in case some strings have not been localized to the user's language:

    Example/lang/strings_english.txt

    <?php
    $s_plugin_Example_title = "Example Plugin";
    $s_plugin_Example_description = "Example Plugin from MantisBT Developers Guide";
    $s_plugin_Example_configuration = "Configuration";
    $s_plugin_Example_foo_or_bar = "Foo or Bar?";
    $s_plugin_Example_reset = "Reset Value";

We can now use these strings to localize our code using the `plugin_lang_get()` API function, replacing the hardcoded text and adding page title:

    Example/Example.php

    	function register() {
    		...
    		$this->description = plugin_lang_get( 'title' );

    Example/pages/foo.php

    <?php
    layout_page_header( plugin_lang_get( 'title' ) );
    layout_page_begin();
    ?>
    ...

    Example/pages/config.php

    <?php
    layout_page_header( plugin_lang_get( 'title' ) );
    layout_page_begin();

    $t_foo_or_bar = plugin_config_get( 'foo_or_bar' );
    ?>

    <form action="<?php echo plugin_page( 'config_update' )?>" method="post">
        <?php echo form_security_field( 'plugin_Example_config_update' ) ?>
        <label>
            <?php echo plugin_lang_get( 'foo_or_bar' ) ?>
            <input name="foo_or_bar" value="<?php echo string_attribute( $t_foo_or_bar ) ?>" />
        </label>
        <br>
        <label>
            <?php echo plugin_lang_get( 'reset' ) ?>
            <input type="checkbox" name="reset" />
        </label>
        <br>
        <button type="submit"><?php echo lang_get( 'change_configuration' )?></button>
    </form>

### ⁠4.2.7. Layout

To finalize our plugin, we'll add some markup and flourishes to make the config page look like a standard MantisBT page.

Note

Alternating colors are applied automatically to the table's rows with CSS, it is no longer necessary to rely on the now-deprecated `helper_alternate_rows()` API function.

    Example/pages/config.php

    <?php
    layout_page_header( plugin_lang_get( 'title' ) );
    layout_page_begin();

    $t_foo_or_bar = plugin_config_get( 'foo_or_bar' );
    ?>

    <div class="col-md-12 col-xs-12">
    <div class="space-10"></div>

    <div class="form-container">
        <form action="<?php echo plugin_page( 'config_update' ) ?>" method="post">
            <?php echo form_security_field( 'plugin_Example_config_update' ) ?>
            <div class="widget-box widget-color-blue2">
                <div class="widget-header widget-header-small">
                    <h4 class="widget-title lighter">
                        <?php
                        print_icon( 'fa-text-width', 'ace-icon' );
                        echo "&nbsp;";
                        echo plugin_lang_get( 'title') . ': '
                            . plugin_lang_get( 'configuration' );
                        ?>
                    </h4>
                </div>

                <div class="widget-body">
                    <div class="widget-main no-padding table-responsive">
                        <table class="table table-bordered table-condensed table-striped">
                            <tr>

                                    </label>
                                </th>
                                <td>

### ⁠4.2.8. Example Plugin source code

The complete source code for the Example Plugin built in this tutorial is available in the mantisbt-plugins GitHub organization.
It has been released into the public domain under the Unlicense, which means you are free to use it in any way you want, without warranty of any kind.

## ⁠4.3. API Usage

This is a general overview of the plugin API. For more detailed analysis, you may reference the file `core/plugin_api.php` in the codebase.

# ⁠Chapter 5. Events Reference

## ⁠5.1. Introduction

In this chapter, an attempt will be made to list all events used (or planned for later use) in the MantisBT event system. Each listed event will include details for the event type, when the event is called, and the expected parameters and return values for event callbacks.
Here we show an example event definition. For each event, the event identifier will be listed along with the event types (see Section 3.3, “Event Types”) in parentheses. Below that should be a concise but thorough description of how the event is called and how to use it. Following that should be a list of event parameters (if any), as well as the expected return value (if any).
⁠

> EVENT_EXAMPLE (Default)

> > This is an example event description.

> > Parameters

> > - <Type>: Description of parameter one
> > - <Type>: Description of parameter two

> > Return Value

> > - <Type>: Description of return value

## ⁠5.2. System Events

These events are initiated by the plugin system itself to allow certain functionality to simplify plugin development.
⁠

> EVENT_PLUGIN_INIT (Execute)

> > This event is triggered by the MantisBT plugin system after all registered and enabled plugins have been initialized (their `init()` functions have been called). This event should always be the first event triggered for any page load. No parameters are passed to hooked functions, and no return values are expected.
> > This event is the first point in page execution where all registered plugins are guaranteed to be enabled (assuming dependencies and such are met). At any point before this event, any or all plugins may not yet be loaded. Note that the core system has not yet completed the bootstrap process when this event is signalled.
> > Suggested uses for the event include:
> > - Checking for plugins that aren't require for normal usage.
> > - Interacting with other plugins outside the context of pages or events.

⁠

> EVENT_CORE_HEADERS (Execute)

> > This event is triggered by the MantisBT bootstrap process just before emitting the headers. This enables plugins to emit their own headers or use API that enables tweaking values of headers emitted by core. An example, of headers that can be tweaked is Content-Security-Policy header which can be tweaked using http_csp_*() APIs.

⁠

> EVENT_CORE_READY (Execute)

> > This event is triggered by the MantisBT bootstrap process after all core APIs have been initialized, including the plugin system, but before control is relinquished from the bootstrap process back to the originating page. No parameters are passed to hooked functions, and no return values are expected.
> > This event is the first point in page execution where the entire system is considered loaded and ready.

⁠

> EVENT_REST_API_ROUTES (Execute)

> > This event is triggered by MantisBT to enable plugins to register their own routes to be accessible via the REST API. All APIs belonging to a plugin named 'Example', MUST live under 'https://.../api/rest/plugins/Example/'. The route registration is done using the Slim Framework app instance that is passed as a parameter. A route group should be used to include all routes for the plugin. The name of the route group should be retrieved via calling plugin_route_group(). See MantisGraph core plugin for an example and Slim Framework router documentation.
> > Before calling into the plugin routes, the user would be already authenticated and authorized for API access in general. However, it is the responsibility of the plugin to do its own plugin specific authorization.

⁠

> EVENT_LOG (Execute)

> > This event is triggered by MantisBT to log a message. The contents of the message should be hyper linked based on the following rules: #123 means issue 123, ~123 means issue note 123, @P123 means project 123, @U123 means user 123. Logging plugins can capture extra context information like timestamp, current logged in user, etc. This event receives the logging string as a parameter.

> > Parameters

> > - <String>: the logging string

⁠

> EVENT_AUTH_USER_FLAGS (First)

> > An event that enables plugins to return a set of flags that control the authentication behaviors for the user who is logging in or logged in. In some cases, the user will be in the system, but there will be cases where the username provided by the user doesn't exist. In case the user doesn't exist, it is up to the authentication plugin whether to fail the login, validate credentials then fail, or validate credentials then auto-provision the user based on information the plugin is aware of (e.g. IDP or some db of accounts). If no plugin is registered for events, then defaults are used. If plugin sets a subset of the options, then the default will be used for the rest.
> > Checkout SampleAuth plugin for more details.

> ⁠

> > EVENT_CRONJOB (Execute)

> > > This is an event that is triggered by the scripts/cronjob.php on some recurring schedule (once an hour is recommended). Plugins handle this event to execute recurring tasks.

## ⁠5.3. Output Modifier Events

### ⁠5.3.1. String Display

These events make it possible to dynamically modify output strings to interpret or add semantic meaning or markup. Examples include the creation of links to other bugs or bugnotes, as well as handling urls to other sites in general.
⁠

> EVENT_DISPLAY_BUG_ID (Chained)

> > This is an event to format bug ID numbers before being displayed, using the `bug_format_id()` API call. The result should be plain-text, as the resulting string is used in various formats and locations.

> > Parameters

> > - <String>: bug ID string to be displayed
> > - <Integer>: bug ID number

> > Return Value

> > - <String>: modified bug ID string

⁠

> EVENT_DISPLAY_EMAIL (Chained)

> > This is an event to format text before being sent in an email. Callbacks should be used to process text and convert it into a plaintext-readable format so that users with textual email clients can best utilize the information. Hyperlinks and other markup should be removed, leaving the core content by itself.

> > Parameters

> > - <String>: input string to be displayed

> > Return Value

> > - <String>: modified input string

⁠

> EVENT_DISPLAY_EMAIL_BUILD_SUBJECT (Chained)

> > This is an event to format the subject line of an email before it is sent.

> > Parameters

> > - <String>: input string for email subject

> > Return Value

> > - <String>: modified subject string

⁠

> EVENT_DISPLAY_FORMATTED (Chained)

> > This is an event to display generic formatted text. The string to be displayed is passed between hooked callbacks, each taking a turn to modify the output in some specific manner. Text passed to this may be processed for all types of formatting and markup, including clickable links, presentation adjustments, etc.

> > Parameters

> > - <String>: input string to be displayed

> > Return Value

> > - <String>: modified input string
> > - <Boolean>: multiline input string

⁠

> EVENT_DISPLAY_RSS (Chained)

> > This is an event to format content before being displayed in an RSS feed. Text should be processed to perform any necessary character escaping to preserve hyperlinks and other appropriate markup.

> > Parameters

> > - <String>: input string to be displayed

# ⁠Chapter 6. MantisBT REST API

The primary means of integrating with MantisBT with web services is with the bundled REST API, which is accessible at `https://server.com/mantis/api/rest/`.

## ⁠6.1. Postman

Postman is a tool to enable REST API development and collaboration. It is used by MantisBT team to share the API definitions and enables the community to experiment with the API. Download Postman.
Once Postman is installed, you should be able to bootstrap it with the MantisBT API collection via the MantisBT API documentation posted on Postman. Download Collection.
The MantisBT API Postman collection is also distributed with MantisBT in the `api/rest/api.postman_collection.json`. The Postman environment template is also available at `api/rest/env.postman_environment.json`.

## ⁠6.2. Exporting Postman Collection

The bundled Postman collection can be updated by clicking on the "..." next to "Mantis Bug Tracker REST API" and choosing "Export...". Then select "Collection v2.1" and click "Export" and select `api/rest/api.postman_collection.json`. Then follow the standard pull request and checkin process.

# ⁠Chapter 7. MantisBT SOAP API

The now deprecated MantisBT SOAP API is accessible at: `https://server.com/mantis/api/soap/mantisconnect.php`.

## ⁠7.1. Java integration

### ⁠7.1.1. Prebuilt SOAP stubs using Axis

For ease of integration of the Java clients, SOAP stubs are maintained and deployed in the Maven central repository. For example:

    <dependency>
        <groupId>biz.futureware.mantis</groupId>
        <artifactId>mantis-axis-soap-client</artifactId>
        <version>1.2.15</version>
    </dependency>

To include them in your project, download the latest available version.

### ⁠7.1.2. Usage in OSGi environments

If you would like to use Axis in an OSGi environment, it is recommended that you use a ready-made bundle, such as the Axis bundle available from Eclipse Orbit

## ⁠7.2. Compatibility between releases

The SOAP API signature will change between minor releases, typically to add new functionality or to extend existing features.
Some of these changes might require a refresh of the client libraries generated, for instance Apache Axis 1 SOAP stubs must be regenerated if a complex type receives a new property. Such changes will be announced before the release of the new MantisBT version on the mantisbt-soap-dev mailing list. Typically there will be two weeks time to integrate the new SOAP stubs.

## ⁠7.3. Support

The primary means of obtaining support for Web Services and the SOAP API is through the mantisbt-soap-dev mailing list.
