Action & Filter Hooks

The framework utilizes some actions and filter hooks to which custom code may be added.

Action Hooks

Name	Passed parameters	Description
'wcf_before_field'	$field The field properties	Hooks just before a field is rendered
'wcf_after_field'	$field The field properties	Hooks just after a field is rendered

 

Filter Hooks

The filters allow to add custom icons, fonts, modify outputs of fields and saved values and prevent the enqueueing of scripts.

If you are altering filters, make sure you always return the first parameter :).
