Template Assign property Has language:

  • Assigns the appropriate "Has language::" property to the page in which it is used.
  • Assigns a default sort key to the page, with the page name after the language code prefix.

This is the behaviour if the template is called without any parameters, and the page name of the current page (where the template is being used) applies.

If a pagename is passed in as first parameter, then the page's language and default sort key are printed, but not assigned. This feature is used below in the examples.

Use

{{Assign property Has language|optional page name}}

Examples

No page parameter

If no first parameter is passed in, the current page applies. This page has no language code, so nothing is returned.
