Template:Mediawiki

{{ #ifeq:

 old.familab.org

| www.mediawiki.org | [[{{{1}}}|{{{1}}}]] | {{{1}}} }}

This template links to a page on from the Help pages. The template has two parameters:

1. Pagename, optionally preceded by an interwiki link prefix valid on mediawiki.org
2. (optional) Link description

{{ #ifeq: old.familab.org | www.mediawiki.org | This is so that the public domain help pages - which can be freely copied and included in other sites - have correct links to Mediawiki:

• on external sites, it creates an external link
• on Mediawiki, it creates an internal or interwiki link

All links from the Help namespace to other parts of the mediawiki.org wiki should use this template.}}

Spaces in Page Titles

These must be replaced with underscores, otherwise the urlencoding mangles them and you get a page not found error on mediawiki.org.

So need {{Mediawiki|Page_Title}} not {{Mediawiki|Page Title}}

Demo of interwiki link

{{mediawiki|m:Help:Calculation|Help:Calculation}} gives either [[m:Help:Calculation|Help:Calculation]] or [http://www.mediawiki.org/wiki/m%3AHelp%3ACalculation Help:Calculation], rendered as Help:Calculation or Help:Calculation, respectively.
