Form validation by my own method

Hey Valery,

If your using form validation, you can use your own function as a callback function to do the necessary checks. You would have to change a couple of things, because a validation function can only pass through the form input which is checked.

You could set it up like this (taken from the user guide with some changes):

PHP Code:

        public function index()

        {
                $this->load->helper(array('form', 'url'));

                $this->load->library('form_validation');

                $this->form_validation->set_rules('username', 'Username', 'callback_username_check');
                $this->form_validation->set_rules('password', 'Password', 'required');
                $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
                $this->form_validation->set_rules('email', 'Email', 'required|is_unique[users.email]');

                if ($this->form_validation->run() == FALSE)
                {
                        $this->load->view('myform');
                }
                else
                {
                        $this->load->view('formsuccess');
                }
        }


        public function username_check($username)

        {
                $password = $this->input->post("password");
               
                $this->load->model("users");
               
                // use a model function to check the credentials
                return $this->users->check_user_pass($username, $password);
                
                // notice: get_access has to return true for success or false when user and/or password are wrong, because you have to tell form validation if your validation checks out or not.
               
        } 


And here you have a username/password validation workaround for 2 variables.

Happy coding!
