 | This is a documentation subpage for Template:Category link if exists. It may contain usage information, categories and other content that is not part of the original template page. |
 | 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.
