Extension:Page Forms/Creating query forms

Forms can also be used for querying, as opposed to adding or editing data. To do so, use the 'Special:RunQuery' page, which displays a form in a manner similar to 'Special:FormEdit', but with no associated 'target page'. Instead, when the user submits the form by hitting the "Run query" button, they see what the template looks like when displayed with the values they entered. The template that the form uses should contain one or more Semantic MediaWiki inline queries, to query data using values the user entered. You can see an example of a query form here.

Set query with pre-loaded values
In case query data needs to be pre-loaded, the 'Special:RunQuery' should follow the convention Special:RunQuery/form-name?template-name[item-name]=value as in the example http://discoursedb.org/wiki/Special:RunQuery/Item_query?ItemQuerier[author]=Joe. The construction [item-name] might cause a problem in connection with the wiki markup therefore [ and ] can be replaced with either %5B and %5D, or &amp;#91; and &amp;#93;.

You can also link to 'Special:RunQuery' where the query has already been run. To do that, just add "wpRunQuery=true" to the query string; see here for an example.
