Editing Help:What links here (section)

==Extensions and programming==
=== Number of backlinks ===
The "What links here" page body has selector body.page-Special_Whatlinkshere, so for example we can use the [[Help:Cascading Style Sheets|CSS]] <code>body.page-Special_Whatlinkshere ul { list-style: decimal }</code> to number the backlinks.

It is possible to obtain the list of backlinks (with additional information) programmatically using the MediaWiki API. For information on how to do this, see the [[mw:API:Backlinks|API documentation]].

=== Semantic relations ===

With the extension [[Semantic MediaWiki]] (SMW) links are categorized by specifying relations. For a given relation the backlinks of a page can be produced in-page. A series of queries, one for each relation (which seems cumbersome but can be put in a template like [http://semanticweb.org/wiki/Template:Ask]), provides an in-page list of backlinks sorted by relation. Moreover, forward links and attributes of the resulting pages can also be provided, and also backlinks of backlinks.

=== DPL method ===

A simpler extension that can embed backlinks (without the semantic functionality) is [[mw:Dynamic Page List|Dynamic Page List]]. '''EXAMPLE NEEDED'''

=== Suppress links ===

"(← links | edit)" can be suppressed by placing the following in Common.css
<syntaxhighlight lang="css">
.mw-whatlinkshere-tools{
    display:none;
}</syntaxhighlight>

'''However, "(transclusion)" can't be suppressed with that CSS. Maybe with CSS# positional-selection.'''

=== Transclusion of WhatLinksHere ===
{{anchor|Transclusion}}
[[Special:WhatLinksHere/Example page]] can be transcluded with <code><nowiki>{{Special:WhatLinksHere/Example page}}</nowiki></code> which produces:
{{Special:WhatLinksHere/Example page}}

If you want to exclude redirects, you can use <code><nowiki>{{Special:WhatLinksHere/Example page|hideredirs=1}}</nowiki></code>. There are three params you can use (in any order, or combination) for hiding redirects, transclusions, or normal links:
*<code><nowiki>{{Special:WhatLinksHere/Example page|hideredirs=1}}</nowiki></code>
*<code><nowiki>{{Special:WhatLinksHere/Example page|hidetrans=1}}</nowiki></code>
*<code><nowiki>{{Special:WhatLinksHere/Example page|hidelinks=1}}</nowiki></code>

=== Workaround to hide transcluded links ===

It is a known limitation that there is no way to filter out pages that link to the current page via a transcluded template. This limits the usefulness of "What links here" in cases where a page is linked to from a widely transcluded navbox. A workaround is to perform a [[Help:Searching|search]] using the [[Help:Searching#insource:|insource]] parameter, e.g. use <code><nowiki>insource:/\[\[[Ff]oo/</nowiki></code> to search for articles that contain links to [[Foo]] (either direct links, <code><nowiki>[[Foo]]</nowiki></code> and <code><nowiki>[[foo]]</nowiki></code>, or [[Help:Piped link|piped links]], <code><nowiki>[[Foo|label]]</nowiki></code> and <code><nowiki>[[foo|label]]</nowiki></code>). A user script, [[User:PrimeHunter/Source links.js]], simplifies this process by providing a link to automatically perform the search.
