The UndeleteBatch extension adds a special page, "Special:UndeleteBatch", where users with the 'undeletebatch' right can undelete multiple pages easily. The user can undelete pages either through the form or by uploading a text file containing the names (and optional undelete reasons) of the pages.


The syntax is:

  • page name|Reason for undeletion

So if you wanted to undelete the page called "Test" with the reason "needed again", you'd type:

Test|needed again

in the form on Special:UndeleteBatch.


  • Download and place the file(s) in a directory called UndeleteBatch in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    require_once "$IP/extensions/UndeleteBatch/UndeleteBatch.php";
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


By default, this extension lets only bureaucrats undelete batches. You can change it to, e.g., let sysops undelete batches:

$wgGroupPermissions['bureaucrat']['undeletebatch'] = false;
$wgGroupPermissions['sysop']['undeletebatch'] = true;
