Template:Category link if exists

Template documentation[view] [edit] [history] [purge]

This template is used on approximately 69,000 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

Preview message: Transclusion count updated automatically (see documentation).

Due to a server limit of 500 "expensive parser function" calls (e.g. #ifexist:, PAGESIZE:, and PAGESINCATEGORY:), this template will only work properly if the page using it has not already exceeded the limit. When the limit is exceeded, the page using this template or module is categorised in Category:Pages with too many expensive parser function calls. (further information)

This is a simple helper template, to be used in other templates. It displays a link to a category if that category exists; otherwise it just displays greyed-out plaintext.

Optional display text may be added as a second parameter.
