Details

[edit]
  • $siteNotice: Empty string, ignored if the hook returns true.
  • $skin: Skin object MW 1.18+

If the function returns false, no attempt will be done to load the sitenotice from interface messages or $wgSiteNotice , and the contents of $siteNotice will be used instead. If the function returns true, there will be no change in behavior of the sitenotice.

Example

[edit]

If the database is read only ($wgReadOnly ) and there's a sitenotice in MediaWiki:Sitenotice you want to override, you can use this hook for that purpose:

$wgHooks['SiteNoticeBefore'][] = function ( &$siteNotice, $skin ) {
	$siteNotice = "There's ongoing maintenance to the site. We'll open editing shortly.";
	return false;
};
