category parameter
Single category
{{#dpl: |category=Countries in North America }}
or
<dpl> category=Countries in North America </dpl>
Result:
<dpl>
category=Countries in North America
</dpl>
Logical OR
Using pipe (or pipe replacement) for logical OR:
{{#dpl: |category=Countries in Africa¦Countries in North America¦Countries in United Kingdom |namespace= }}
or
<dpl> category=Countries in Africa|Countries in North America|Countries in United Kingdom namespace= </dpl>
Result:
<dpl>
category=Countries in Africa|Countries in North America|Countries in United Kingdom namespace=
</dpl>
Logical AND with logical OR
Logical OR with logical AND by using a second category statement.
{{#dpl: |category=Countries in North America¦Countries in United Kingdom |category=Part of NATO }}
Other invocation examples |
---|
Parser function invocation {{#dpl: |category=Countries in North America{{!}}Countries in United Kingdom |category=Part of NATO }} or Tag/parser extension invocation <dpl> category=Countries in North America|Countries in Europe category=NATO membership debates </dpl> |
Result (identical output regardless of invocation method):
{{#dpl: |category=Countries in North America¦Countries in United Kingdom |category=Part of NATO }}
Include direct subcategories
If you put a *
before the name of a category, DPL will add all DIRECT subcategories of that category to your statement.
Using TWO asterisks ( **
) will extend the tree search to two levels. This provides some minimal support for hierarchies of categories. The syntax and/or semantics of this feature might be changed in a future version.
{{#dpl: |category=+Countries in Africa¦Countries in Europe |category=*Part of NATO |headingmode=ordered }}
Result:
{{#dpl: |category=+Countries in Europe¦Countries in Africa |category=*Part of NATO |headingmode=ordered }}
Must be in 2 categories
To find all articles that are in two category, such as all Country examples and Part of NATO, an example would be:
{{#dpl: |category = Country examples |category = Part of NATO }}
Result:
{{#dpl:
|category = Country examples
|category = Part of NATO
}}
Must be in 1 category and another (one of multiple)
Or to find all articles that contain one category name, and then another category name from two possible options, such as listing all the chairs that are made of wood as well as all the chairs that are made of metal, would be:
{{#dpl: |category = Country examples |category = NATO membership debates | Part of NATO }}
Result:
{{#dpl:
|category = Country examples
|category = NATO membership debates | Part of NATO
}}
Sorting results alphabetically
Sort articles alphabetically, disregarding the namespace in the order (sorting for "Category:NATO membership debates" would sort by the "N" in "NATO" rather than the "C" in "Category".
{{#dpl: |category = Part of NATO |ordermethod = titlewithoutnamespace |order = ascending }}
Result:
{{#dpl:
|category = Part of NATO
|ordermethod = titlewithoutnamespace
|order = ascending
}}
