Settings definitions allows for a field "on_change". Can anyone explain how to use this? I would like to have it execute a function that I have defined in my extension when my quickform is saved.

THanks!

on_change is executed when setting value is changed. You can either set it 

 'on_change' => [
   ['CLASS_NAME', 'functionName'],
 ],

Else 

'on_change' => [
  'CLASS_NAME::functionName',
],

A good example would be https://github.com/civicrm/civicrm-core/blob/master/settings/Localization.setting.php#L145

  • Is there any way to pass values through this? Or do I need an API call in my function to get the new value for the setting? – Sleewok Aug 8 '18 at 13:38
