Template documentation (for the template shown above, sometimes hidden or invisible)
Description
- This helper-template is used to determine if a page has any value for a certain property.
- It won't output anything at all when it can't find the property for the page, and simply output a 'yes' when it can.
- This behavior is essential for use in
{{#if:}}constructs.
Syntax
- Type the below code somewhere inside your code:
{{HasProp|propname|page=pagename}}- propname must be provided, as an un-named parameter! (else it will always output 'yes' as you can see..)
- page is an optional parameter and defaults to
{{FULLPAGENAME}}, this is to aid in debugging pages and examples....
Examples
Visit Template:HasProp/doc to edit this text! (How does this work?)
