Het plaatsen van advertenties of andere banners kan nuttig zijn voor wiki's, vooral kleine wiki's die advertenties nodig hebben om geld te genereren om de serverkosten te compenseren. Het plaatsen van advertenties kan een uitdaging zijn voor gebruikers die geen ervaring hebben met MediaWiki. Een aantal van de uitdagingen zijn:

  • Het vinden van een manier om de advertentie op elke pagina van de wiki te krijgen – het is niet zo effectief om de code handmatig aan elke pagina toe te voegen, wat mogelijk is met een sjabloon.
  • Beveiligingsoverwegingen – Veel HTML-tags en JavaScript kunnen niet aan pagina's worden toegevoegd, waardoor de code niet in afzonderlijke pagina's of de sitenotice kan worden geplakt. Het inschakelen van dergelijke functionaliteit is uiterst gevaarlijk en zal ertoe leiden dat uw website wordt gehackt.
  • De code op de juiste plaats opslaan – Iemand met kennis van MediaWiki HTML zou een banner kunnen toevoegen aan het relevante PHP-bestand, maar dit zou tijdens elke upgrade worden verwijderd. Het kan ook moeilijk zijn om te weten waar de code moet worden geplaatst.

Scripts en extensies voor het plaatsen van advertenties

Banners toevoegen aan skins op andere plaatsen dan de site notice

Alle moderne skins ondersteunen de toevoeging van banners in de zijbalk en onderaan de skin met behulp van de SkinAfterPortlet (sinds Mediawiki 1.35) en SkinAfterContent hooks. Er moeten geen extensies of skin nodig zijn.

	public function onSkinAfterPortlet( $skin, $portletName, &$html ) {
		$key1 = 'AD1'; // <== Place this key in the MediaWiki:Sidebar
		$key2 = 'AD2'; // <== Place this key in the MediaWiki:Sidebar
		$html_snippet1 = '<div style="">Potential banner location.</div>';
		$html_snippet2 = '<div style="">Potential banner location.</div>';
		$sidebar_elements = [];
		$sidebar_elements[$key1] = $html_snippet1;
		$sidebar_elements[$key2] = $html_snippet2;

		if ( array_key_exists( $portletName, $sidebar_elements ) ) {
			$element = $sidebar_elements[$portletName];
			if ( !empty( $element ) ) {
				$html = $element;
				return true;
			}
		}
	}

	public function onSkinAfterContent( &$data, $skin ) {
		$data .= '<div style="">Potential banner location on the bottom.</div>';
	}

The following information is outdated. The collapsible feature has been removed from the Vector skin. The collapsible navigation portals are now provided by the CollapsibleVector extension which will have to be installed additionally.[1]

    One of the problems with placing advertising in the Vector sidebar is that the sections are collapsible, meaning that many visitors will not see advertisements if they are not properly put it. The problem is that locking a sidebar section open requires technical server side scripting that some users might not want to do. This script places the code of the banner above the title of the section, and displays whether or not the section is expanded.
    To use this script, add it to the MediaWiki:Vector.js page and change the referenced ID of the sidebar section to the ID of the section where you want to add the banner.

Howto

There are a number of existing advertisement extensions for MediaWiki that may serve as examples of how it can be done.

There are a few different ways to inject ad banners into a MediaWiki skin:

  • Edit the skin template itself (e.g. skins/Vector.php for the Vector skin) and add the banner code in a suitable location. This is a fairly quick and easy solution, but suffers from the problem that you'll need to redo it every time you upgrade MediaWiki (or upgrade your skin, if you're using a non-standard one).
  • Find a suitable hook to inject the banner code into the skin. If you're just doing this for your own wiki, you can simply write the hook code directly into your LocalSettings.php (or into a separate PHP file that you include from there, if you prefer), but you could also turn it into a full MediaWiki extension (which basically just means, at a minimum, putting it in a separate file and adding a bit of boilerplate code).
  • Alas, finding the right hook for the job may not always be trivial. For injecting ads into the sidebar, the SkinBuildSidebar hook may be convenient; SkinAfterContent might work for footer ads, and for top ads, you could maybe (ab)use the SiteNoticeAfter hook.
  • Create a parser tag extension that allows you to add a custom tag like ‎<adshere /> to your pages to inject the ad banner code at that location. Straightforward, but requires you put the tag on any page that you want ads on (or in an interface message, if you can find a suitable one; tip: try appending the parameter uselang=qqx to URLs to see which messages are used where).
  • Find a suitably located interface message which is treated as raw HTML, and put your ad code there directly. Alas, there aren't many such messages, and the trend is towards getting rid of the few that are left.
  • For ads that can be injected with JavaScript only, you can simply put the code in MediaWiki:Common.js (or in the appropriate skin-specific JS page).[2]
