The AddMessages extension allows admins to add or replace default messages using a global variable. This can be set in LocalSettings.php. Other extensions could potentially set this variable or implement similar code in order to add messages. This used to be possible with $wgMessageCache->addMessage() but that feature has been removed. This feature is particularly useful in wikifarms, where it may not be practical to add a particular message to every individual site.

Installation edit

  • Download and move the extracted AddMessages folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/AddMessages
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'AddMessages' );
    $wgAmMessages = array();
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration parameters edit

An array of message key and value pairs. Will take precedence over existing messages. Example:
$wgAmMessages = array( 'toolbox' => 'My Toolbox' );
