Manual:Extension/Page Forms/Snippets

Providing input values from a (sub-) category

Using input type "tree"

(see official documentation: mediawiki.org/wiki/Extension:Page_Forms/Input_types#tree )

{{{field|doctype|input type=tree|top category=Document type|depth=1|hideroot|list}}}

Form display:

Field type tree

Example output of template parameter: doctype=Process

Using DPL query (dropdown)

(Solution found at: https://www.mediawiki.org/wiki/Extension_talk:DynamicPageList3#Return_page_titles_as_plain_text?

{{{field
 | doctype
 | input type=dropdown
 | values = {{#dpl: namespace = Category
 | category = Document type
 | mode = inline
 | format = ,¶%TITLE%,,
 | inlinetext = ,
  }}
}}}

Form field:

values provided by dpl3 parser function

Example template output:

doctype=Process

Using an SMW inline query

{{{field|doctype|input type=dropdown|values={{#ask: [[Subcategory of::Document type]]|format=plainlist|sep=,|link=none|template=SMW Pagename}} }}}

The above example uses the mapping template Template:SMW Pagename to avoid showing the namespace prefix "Category:" in the dropdown. Create the template with the following content:

{{PAGENAME:{{{1|}}} }}

Although the category prefix is then not shown in the dropdown, the value the form passes to its associated template parameter still includes the namespace prefix.

Example template output:

doctype=Process

Using an SMW concept

Create the page Concept:Doctype with the following content:

{{#concept:
 [[Subcategory of::Documenttype]][[Modification date::+]]
 |List of sub categories of the category Documenttype
}}

Use this concept as the source for the values of your field:

{{{field|doctype|input type=dropdown|values from concept=doctype|mapping template=catConcept}}}

The above example uses the mapping template Template:catConcept to avoid showing the namespace prefix "Category:" in the dropdown. Create the template with the following content:

{{PAGENAME:{{{1|}}} }}

Although the category prefix is then not shown in the dropdown, the value the form passes to its associated template parameter still includes the namespace prefix.

Example template output:

doctype=Category:Process
