قالب:FindYDCportal

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

A helper template to find the most specific chronology portal which actually exists for a given year or decade. Used to simplify linking to a chronology portal.

It is a wrapper template around Module:FindYDCportal. For use within templates, it is most efficient to invoke the module directly. For one-off use, the template requires less typing and makes the code easier to read.

 Parameters

Takes one parameter, which must be either a year (e.g. "1879", "1123") or a decade (e.g. "1940s", "730s").

If the parameter is missing, empty, or does not fit the required format, an empty string is returned.

 Output

If a portal is found, returns its name without the namespace prefix, e.g.

• for "Portal:1980s" return 1980s
• for "Portal:19th century" return 19th century

If no portal is found, it returns an empty string.

 Usage

Year parameter

{{FindYDCportal|YYYY}} ... where YYYY is a 3- or 4-digit year

Decade parameter

{{FindYDCportal|YYY0s}} ... where YYY0s is a 3- or 4-digit decade
