If you're wondering why your extension broke with the Vector skin, please see Manual:Hooks/SkinTemplateNavigation. Vector uses a different hook.

Warning Warning: MediaWiki 1.18 now uses the Vector-style hook for all skins, please see Manual:Hooks/SkinTemplateNavigation for the vector and 1.18 equivalent of this hook.


Called after building the $content_actions array, but before returning it. The $content_actions array can be modified to add/remove tabs.

Typically if you want to add new tab with caption mytab that has hyperlink to the page you should add a new element to the $content_actons array in your function :

 $content_actions['newtab'] = array (
 'class' => false,
 'text'  => 'mytab',
 'href'  => '',
  • Tip: Always return true, otherwise other extensions that have hooked this event will not function properly!


  • $skin: the skin it was called from
  • $content_actions: The array of content actions. Each content action is an array that includes text of the caption of the tab and hyperlink.
