Tips and Tricks

Recommendation from Neill: I always hide the raw page name as much as possible and use aliases so queries return more user friendly links.

{{#set:Page Link=[[{{FULLPAGENAME}}|{{{Page Title|}}}]]}} where Page Title is usually a field in the form. Sometimes I prepend with a section ID {{#set:Page Link=[[{{FULLPAGENAME}}|{{{Section ID|}}}-{{{Page Title|}}}]]}}

Then in the queries I return Page Link and use mainlabel=- to suppress the raw page name field.

{{#ask: |?Page Link .. .. |mainlabel=- }}

Note:

  • <section id="main"> <!-- main page content goes in here --> </section>
  • define Page Link as a Special:Property
