Private function and Custom form validation

Yes, http://ellislab.com/codeigniter/user-gui...ml#private

Code:

function _check_terms(){}

$this->form_validation->set_rules(fieldname, labelname, 'callback__check_terms');//2 underscores

Since callback prefixes are "callback_", and the private function is "_check_terms", it ends up being "callback__check_terms" with 2 undrescores
