The RelatedArticles extension adds a parser function to your wikitext that allows associating related articles with your article. It shows related pages as a list of articles and their descriptions at the bottom of a page on desktop and mobile. The extension is also smart enough to get the list of related articles using the morelike feature of CirrusSearch.

Usage[edit]

Once installed Related articles will be determined algorithmically based on Cirrus Search if available with no additional steps. Alternatively, you can disable this functionality ($wgRelatedArticlesUseCirrusSearch) and manually add related articles like so:

{{#related:Test with read more}}
{{#related:Another test page}}

Prerequisites[edit]

If EventLogging is installed, the RelatedPages feature can be configured to log events. It is not required.

If PageImages is installed, Related Articles will include the page's selected image (if any). Otherwise, a placeholder image will be used instead. This extension is not required.

Depending on the configuration of $wgRelatedArticlesDescriptionSource (see below), a small description of each page can be fetched, provided by one of those extensions, which aren't required. Description won't be provided if the extension isn't available.

Installation[edit]

Download and place the file(s) in a directory called RelatedArticles in your extensions/ folder.

Add the following code at the bottom of your LocalSettings.php:
```
wfLoadExtension( 'RelatedArticles' );
```
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

To users running MediaWiki 1.24 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension(). If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'RelatedArticles' );, you need to use:

require_once "$IP/extensions/RelatedArticles/RelatedArticles.php";

Configuration[edit]

Related articles will be shown at the bottom of the skin. Note that the page must be in the Main namespace, and being viewed (as opposed to edited for example), and not be a disambiguation or a diff page, and the skin name (e.g. minerva) that's being used is in the array $wgRelatedArticlesFooterWhitelistedSkins (see below).

The following configuration options apply:

If EventLogging is installed, set the event logging sampling rate $wgRelatedArticlesLoggingSamplingRate using a number between 0 and 1. The schema used for logging is RelatedArticles .
Use morelike feature of CirrusSearch by setting $wgRelatedArticlesUseCirrusSearch to true. If CirrusSearch is not available fallback to using the related articles marked in wikitext.
Use only CirrusSearch's morelike feature by setting $wgRelatedArticlesOnlyUseCirrusSearch to true ignoring the related articles marked in wikitext.
$wgRelatedArticlesFooterWhitelistedSkins List of skin names (e.g. 'minerva', 'vector') where related articles will be shown in the footer. For example, on a wiki with Monobook, Vector and Minerva installed$wgRelatedArticlesFooterWhitelistedSkins = ['vector'] will result in the widget showing on Vector only.
A small description of the page will be displayed below the title of the page, depending on the value of $wgRelatedArticlesDescriptionSource:
- wikidata: Requires Wikibase Client, from the central wikibase repository.
- textextracts: Requires Extension:TextExtracts, fetched from the prop=extracts api.
- pagedescription: Requires Extension:Description2 (or any other extension that sets the description page property).
