The Contributors extension provides an includable special page which summarizes the most prominent contributors to an article. The page can be accessed as a normal special page, or included into other pages to provide an automated list, which is useful for attribution.


  • Download and place the file(s) in a directory called Contributors in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    require_once "$IP/extensions/Contributors/Contributors.php";
  • Run the update script which will automatically create the necessary database tables that this extension needs.
  • Run the script that will populate the database with contributors from existing articles:
php extensions/Contributors/maintenance/PopulateContributorsTable.php
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


The list can be accessed as a conventional special page, or through inclusion into another page.

Special page

The special page is located at "Special:Contributors" and provides an interface to select an article. You can also access this page using the "main contributors" link in the toolbox when viewing an article; the results for that page will be shown.


You can transclude a list of names into another page using the inclusion mechanism, e.g.


You can also create a template with the following code on it, and add it to your articles.


will produce a list of the most prominent contributors to Article.


By default, the list is sorted by number of edits, in descending order. It is possible to sort by user name and to switch the order to ascending. This is done with a parser function. For example:


This switches the sort to be alphabetical by user name, ascending. These options are also available at Special:Contributors.


  • $wgContributorsLinkUsers links the user names to their User page. Doesn't affect the Special page, which is always linked. (default true)

Output criteria

This extension lists "prominent contributors" to a page. The default behaviour will show all contributors, in order of number of edits, if the number of contributors is ten or less. Once the limit is hit, contributors with over two edits will continue to be listed. Contributors who are not listed are acknowledged as "X others".

These limits can be changed:

  • $wgContributorsLimit defines the "intelligent cut-off" limit (default 10)
  • $wgContributorsThreshold defines the edit threshold for additional users (default 2)
