The MetaDescriptionTag allows users to add a ‎<meta> description into a page's ‎<head>.

Installation edit

  • Download and place the file(s) in a directory called MetaDescriptionTag in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'MetaDescriptionTag' );
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Usage edit

Once installed, editors of your wiki can add a ‎<meta> description tag by adding the following to the article text:


Where PageDescription would be replaced by the desired meta description.

For example, the above would become:

<meta name="description" content="PageDescription" />

Usage through a template edit

Say for example you want use a template to set the meta description to something like:

<metadesc>Extract from the article ARTICLETITLE</metadesc>

Create a template called (for example) "Template:Metadesc". Add the following content:

{{#tag:metadesc | Extract from the article {{{1}}} }}

In the article to which you set the meta description, add:

{{metadesc|{{PAGENAME}} }}

Changelog edit


This is re-write to make it compatible with more modern MediaWiki practices and make sure it works nicely with MediaWiki 1.27+:

  • Extension Registration (extension.json)
  • json i18n files - An actual README file! :-)
  • Switching to semantic versioning.

Fix i18n to work with v1.16+, sanitize output using htmlspecialchars().


Change syntax to <metadesc>some content</metadesc> to support template variable substitution.


Initial release.
