Resolves a soft category redirect.
It takes one parameter, which is the name of a category. It returns that category name, unless the category exists and is a {{Category redirect}} ... when it returns the name of the redirect target.
Usage
ಬದಲಾಯಿಸಿ{{Resolve category redirect|categoryname}}
Examples
ಬದಲಾಯಿಸಿ- Category exists and is not redirected
- Category:1970s
{{Resolve category redirect|1970s}}→ 1970s{{Resolve category redirect|Category:1970s}}→ Category:1970s
- Category exists and is a soft redirect
- Category:Mosques completed in the 19th century
{{Resolve category redirect|Mosques completed in the 19th century}}→ 19th-century mosques{{Resolve category redirect|Category:Mosques completed in the 19th century}}→ 19th-century mosques
- Category exists and is a soft redirect
- Category:Organisations
{{Resolve category redirect|Organisations}}→ Organizations{{Resolve category redirect|Category:Organisations}}→ Organizations
- Non-existent category
- Category:Colourless green things
{{Resolve category redirect|Colourless green things}}→ Colourless green things{{Resolve category redirect|Category:Colourless green things}}→ Category:Colourless green things
Templates
ಬದಲಾಯಿಸಿDo not use templates in the target name.
{{Resolve category redirect}} cannot expand any templates in the target name, and the { character caused crashes (as did } and !). So it does not attempt to resolve any redirect where the target includes those characters.
- Example
- Category:1781 in Mexico contained
{{category redirect|{{title year}} in New Spain}}which cannot be resolved. To be safe,{{Resolve category redirect|1781 in Mexico}}simply returned1781 in Mexico.
The above example has since been changed to{{category redirect|1781 in New Spain}}, which can be resolved.
Avoiding deletion of the redirected page
ಬದಲಾಯಿಸಿIf the parameter |keep=yes is included in the category redirect, this hides a speedy deletion button that is otherwise displayed to administrators.
It is helpful to also add {{R from category navigation}} to indicate that the redirect is required for navigation between category pages. See that template page for full syntax.
