I don't see it documented anywhere. It really should be. But I figured it out.

An example is attached. Once you have uploaded the files then you need to specify the callback for your profile field:

Then edit the code:


It has a basic skeleton you can use to validate the value of a profile field:


class Callback_UserField
	public static function validate($field, &$value, &$error)
		if ($value == '123')
			return true;
			$error = 'what no';
			return false;
