Details

This hook allows alteration of the footer.

Parameters:

• $skin: the Skin object
• $key: the current key for the current group (row) of footer links. Currently either info or places.
• &$footerItems: the array of links that can be changed. Keys will be used for generating the ID of the footer item; values should be HTML strings.

Default footer items

• info:
  • lastmod: timestamp of last modification of the current page (only when $wgMaxCredits is set)
  • numberofwatchingusers: obsolete(?)
  • credits: list of contributors to the current page (only when $wgMaxCredits is set)
  • copyright: copyright information (see $wgRightsText and related settings)
• places:
  • privacy: privacy policy (shows text from MediaWiki:Privacy, links to the page set in MediaWiki:Privacypage)
  • about: about page (shows text from MediaWiki:Aboutsite, links to the page set in MediaWiki:Aboutpage)
  • disclaimer: disclaimers page (shows text from MediaWiki:Disclaimers, links to the page set in MediaWiki:Disclaimerpage)

Setting a text-generating message for one of the places items to - removes that item from the footer. For instance to disable the "Disclaimers" link, you should edit MediaWiki:Disclaimers and set its content to "-" or set it to be blank.

    if ( $key === 'places' ) {
        $footerlinks['test'] = $skin->footerLink( 'test-desc', 'test-page' );
    }

public static function onSkinAddFooterLinks( Skin $skin, string $key, array &$footerlinks  ) {
    if ( $key === 'places' ) {
        $footerlinks['my_url'] = Html::rawElement( 'a', [ 'href' => 'https://my.url/' ], 'My URL' );
    }
