IssueTracker - Listing Page


The IssueTracker extension provides a custom tag, <issues />, that allows the inclusion of an issue tracker in any wiki page. It's possible to customize almost every aspect of the extension, such as permissions, user groups, colours, titles, and templates. It supports searching and several types of filtering.

To embed an issue tracker into a page, use the <issues /> tag:

<issues />

If a project name is not provided, the extension will use the page namespace as the default project name. You can create multiple issue trackers by providing different project names, for example:

<issues project="My Project" />

To hide the filter and search forms you can set the search and filter options to false:

<issues project="My Project" search="false" filter="false" />

By default, users must be logged in to add, edit or achieve issues. If you want to allow anonymous issue management, set the authenticate option to false:

<issues project="My Project" authenticate="false" />


  • project = String : The project name (default: page namespace).
  • authenticate = Boolean : User authentication (default: true).
  • search = Boolean : Display search form (default: true).
  • filter = Boolean : Display filter form (default: true).


The IssueTracker extension requires MediaWiki 1.9.0 or greater.


Archive File[edit]

Available formats: zip | tar.gz

Subversion Repository[edit]

Use SVN to checkout a copy of the source code. I highly recommend you to get the trunk version of the extension until a stable version is released. I do what I can to ensure that SVN versions are build-able and run-able, but clearly beta versions in SVN should not be considered stable.

Check out the current development trunk with:

$ cd extensions/
$ svn checkout http://svn.fedecarg.com/repo/MediaWiki/IssueTracker/trunk/ IssueTracker


1. Copy the IssueTracker/ directory into the extensions folder of your MediaWiki installation. Note: Make sure that the extensions/ directory and the IssueTracker/ directory are both readable and executable by everyone.

2. Add the following line to the LocalSettings.php file:

require_once $IP . '/extensions/IssueTracker/IssueTracker.php';

3. Create the database table, executing the following script on your MySQL administration tool. In case you are using Wiki SQL table prefixes, do not forget to add that prefix as prefix to the table name issue_tracker.

CREATE TABLE `issue_tracker` (
  `issue_id` int(10) NOT NULL auto_increment,
  `type` varchar(5) NOT NULL default 't_bug',
  `title` varchar(100) NOT NULL,
  `summary` text NOT NULL,
  `status` varchar(5) NOT NULL default 's_new',
  `assignee` varchar(40) NOT NULL,
  `user_name` varchar(40) NOT NULL,
  `user_id` int(10) NOT NULL,
  `project_name` varchar(100) NOT NULL,
  `deleted` int(1) NOT NULL default '0',
  `history` text NOT NULL,
  `priority_date` datetime NOT NULL default '0000-00-00 00:00:00',
  `date_created` timestamp NOT NULL default CURRENT_TIMESTAMP,
  PRIMARY KEY  (`issue_id`),
  KEY `user_id` (`user_id`)


Customization options are available and can be set in the IssueTracker.config.php file.

Issue Types[edit]

You can add as many issue types as you want, for example:

$perms['add']      = array('group' => '*');
$perms['edit']     = array('group' => '*');
$perms['archive']  = array('group' => '*');
$perms['delete']   = array('group' => '*');
$perms['assign']   = array('group' => 'sysop');
$perms['assignee'] = array('group' => 'devel');

By default:

Known Bugs[edit]

Can't edit a bug in MW 1.19[edit]

In MediaWiki 1.19.2 (perhaps before), editing a bug throw the PHP error Argument 1 passed to UsersPager::__construct() must implement interface IContextSource, string given.

To solve this, in Actions/IssueTrackerActionAdd.php, change from

118   /** @see SpecialListusers **/
119   require_once 'SpecialListusers.php';
121   $users = new UsersPager($group);
122   if (! $users->mQueryDone) {
123     $users->doQuery();
124   }


118     /** @see SpecialListusers **/
119     require_once 'includes/specials/SpecialListusers.php';
121     $specialListUsers = new SpecialListUsers();
122     $users = new UsersPager($specialListUsers->getContext());
123     if (! $users->mQueryDone) {
124       $users->doQuery();
125     }

Can't add more than one issue tracker on a page[edit]

More than one issue tracker on a page is not properly supported. It looks fine, but when you create a new issue, it creates a new issue for every issue tracker on that page, with the exact same content, into the one tracker.

A possible solution I thought would be to add issue tags with a different project attribute. This instead created 3 issues in the same tracker. But that is different than the results above which would have created 1 in each of the 3.

Path bug[edit]

1.13.3 bug found

the same applies for 1.14.0, 1.15.1 and 1.16.0 also

Open: IssueTracker/Actions/IssueTrackerActionAdd.php


protected function _getUsers()

Change: After the opening curly bracket ( { ), add "global $IP;"


require_once 'SpecialListusers.php';

Change to:

 require_once( $IP."/includes/specials/SpecialListusers.php" );

Special Pages name bug[edit]

In the current trunk (I don't know about 1.15) the "special pages" page of Issue Tracker is set to "Special:Issue_Tracker", which breaks the code. The new code apparently gets this name from a different source then it used to. To change this behavior open:

neno extensions/IssueTracker/IssueTracker.i18n.php

and edit the first variable, so that "Issue Tracker" becomes "IssueTracker"

$messages['en']['issuetracker'] = 'IssueTracker';

Issue titles with quotes display incorrectly[edit]

Due to the procedure by which information from the database is displayed on the page, quotes in an issue title will be interpreted as HTML, and thus the title will appear truncated. To fix this bug, changes need to be made to 3 files:

  • <td class="<?php echo $issue->status; ?>"><?php echo htmlspecialchars($issue->title); ?></td>
    should be
    <td class="<?php echo $issue->status; ?>"><?php echo htmlspecialchars($issue->title, ENT_QUOTES); ?></td>
  • <td><?php echo htmlspecialchars($issue->user_name); ?></td>
    should be
    <td><?php echo htmlspecialchars($issue->user_name, ENT_QUOTES); ?></td>
  • <td><span class="<?php echo $issue->status; ?>"><?php echo htmlspecialchars($issue->title); ?></span></td>
    should be
    <td><span class="<?php echo $issue->status; ?>"><?php echo htmlspecialchars($issue->title, ENT_QUOTES); ?></span></td>
  • <td><?php echo htmlspecialchars($issue->assignee); ?></td>
    should be
    <td><?php echo htmlspecialchars($issue->assignee, ENT_QUOTES); ?></td>
  • echo (isset($_POST['bt_title'])) ? $_POST['bt_title'] : '';
    should be
    echo (isset($_POST['bt_title'])) ? htmlspecialchars($_POST['bt_title']) : '';

User Groups (Special:UserRights) link broken[edit]

The "User Groups" link, at the bottom of the issue tracker, is broken when using Short Urls. To fix, in IssueTracker\Views\list.html replace (found at the end of the file):

<?php if ($this->isAllowed): ?>[<a href="/index.php?title=Special:UserRights">User groups</a>]<?php endif; ?>


<?php global $wgScriptPath;  if ($this->isAllowed) { echo "<a href='{$wgScriptPath}/index.php?title=Special:UserRights'>User groups</a>"; } ?>
