Publicidad

Colocar anuncios u otros banners puede ser útil para las wikis, sobre todo para las pequeñas que necesitan publicidad para generar dinero con el que compensar los costes del servidor. Colocar publicidad puede ser un reto para los usuarios que no tienen un conocimiento experimentado de MediaWiki. Algunos de los desafíos pueden incluir:

• Necesidad de encontrar una manera de poner el anuncio en cada página de la wiki – Añadir el código manualmente a cada página, lo cuál es posible con una plantilla, no sería muy efectivo.
• Consideraciones de seguridad – Muchas etiquetas HTML y JavaScript no se pueden añadir a páginas, previniendo que el código sea pegado a páginas individuales o el sitenotice . Habilitando tal funcionalidad es extremadamente peligroso y resultará en que tu sitio sea hackeado.
• Manteniendo el código en un lugar apropiado – Alguien con conocimiento de HTML MediaWiki podría añadir un banner al archivo PHP relevante de apariencia, pero esto sería destruido durante cualquier actualización. También podría ser difícil que alguien sepa dónde poner el código.

Añadir banners a apariencias en lugares además del site notice

Todas las apariencias modernas soportan la adición de banners en el sidebar y al fondo de la apariencia usando el SkinAfterPortlet (desde MW 1.35) y SkinAfterContent hooks. No se deberían necesitar extensiones o apariencias especiales.

	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The following information is outdated.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.

  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).
