Hi
Can anyone see why the callback function in my form validation (process() function) is not working? The function is just not getting called (validate_username())
It was working...then all of a sudden it doesn't!
Code:
<?php
class Login extends Controller {
private $user = '';
public function Login() {
parent::Controller();
// if already logged in, then redirect to dashboard!
if ( $this->authentication->confirm() ) redirect ( 'dashboard', 'location');
// load the users model
$this->load->model ( 'musers' );
}
public function index() {
// load login form
$content = $this->load->view ( 'content/login/form',null,true);
// load main layout
$this->load->view ( 'layouts/main', array ( 'content' => $content ) );
}
/*
function: process
scope: public
desc: processes supplied login information
*/
public function process() {
// make sure the post field "process_login" is set to 1
if ( $this->input->post ( 'process_login') == '1' ) {
// get the user and pass
$username = $this->input->post ( 'username' );
$password = $this->input->post ( 'password' );
// set validation rules
$this->form_validation->set_rules ( 'username', 'Username', 'required|callback_validate_username' );
$this->form_validation->set_rules ( 'password', 'Password', 'required' );
// make sure the form validates
if ( $this->form_validation->run() ) {
// check password
if ( $this->user[0]['password'] == $password ) {
// all ok - log the user in
$this->authenication->set ( array ( 'logged' => '1', 'username' => $username ) );
} else {
$this->index();
}
} else {
// something went wrong!
// show the login form
$this->index();
}
} else {
// show login form
$this->index();
}
}
/* function: validate_username
scope: public
desc: validates the username exists
*/
public function validate_username ( $username ) {
if ( $user = $this->musers->single ( $username ) != false ) {
$this->user = $user;
return true;
} else {
$this->form_validation->set_message ( 'validate_username', 'The username you supplied is invalid!');
return false;
}
}
}
