Anonymous function Validation

Hi,

I would put the model call into a callback, something like this:

PHP Code:

$this->form_validation->set_rules( 'email', 'Email Address', 'trim|required|valid_email|callback_permission_check'); 


And your callback function in your controller would look something like:

PHP Code:

private function permission_check() {
     // load your model
     $this->load->model('usermodel');
     
     // set error message
     $this->form_validation->set_message( 'permission_check', 'This user already has access.' );
     
     // get your variables
     $email = $this->input->post('email', TRUE);
     $user_id = ? // not sure how you are getting this but you cannot pass it in the function call
     
     // do the check
     if($this->usermodel->permission_exists($email, $user_id)) return TRUE;

     return FALSE;
} 


In that way you can still set an error message. I read you link and have never used that method, so sorry if the above suggestion is a bit off topic.
