KLlinkparam MediaWiki Extension

This extension allows linking to articles with parameters.

Usage

{{#linkparam:Article|parameter=value|link text}}

The link [[Contact?subject=Hello]] looks like it should send a parameter to the Contact page, but it doesn’t. MediaWiki interprets the entire link as an article name, like this: Contact?subject=Hello. Use this extension to send parameters like this.

like this: {{#linkparam:Contact
| subject=Just testing the link
  & message=Kenny,

I tested the link. It worked. If you’re reading this, I actually sent the message instead of canceling.
| like this}}.

The extra returns in the parameter are urlencoded and become part of the message. Other returns simply make it easier to read the code. Remember: only use ampersands and equal signs to divide the URL parameters—never within a parameter.
