Амодуль:UserLinks


This module generates links about a given user. It is used to generate templates such as {{user}}, {{user5}}, and {{admin}}, usually through its wrapper template {{user-multi}}.

Functions

аредакциазура

Main

аредакциазура

The main function implements the {{user-multi}} template. It generates a list of links about a given user. Please see the template page for documentation.

Single

аредакциазура

The single function generates a single link about a given user. See {{user-multi/link}} for documentation.

аредакциазура

The linktable function generates a wikitext table containing the possible link codes that can be used with the main and single functions, along with example output for each code. It is used on the documentation pages at Template:User-multi/doc and Template:User-multi/link/doc.

It is displayed with the following code: 

{{#invoke:UserLinks|linktable}}

Porting to other wikis
