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=- }}

Example

ongoing projects, based on [[Category:Project]] [[Due_date::> {{#expr:{{#time: Y|now}}}}]]

  • CURRENTYEAR is 2024, CURRENTTIME is 10:41, LOCALTIME is 10:41
  • date: 25 Februar 2016 or "now": 06 May 2024
  • see all time examples in: Help:Extension:ParserFunctions
