You need to modify My_Controller.php and the login verification module User.php of the controller. The code is as follows:
class MY_Controller extends CI_Controller { public function __construct() { parent::__construct(); /*判断是否登录,判断当前URL是否是auth/login*/ if ( ! $this->tank_auth->is_logged_in() && ( $this->router->fetch_class() != 'auth' && $this->router->fetch_method() != 'login')) { $redirect = $this->uri->uri_string(); if ( $_SERVER['QUERY_STRING']) { $redirect .= '?' . $_SERVER['QUERY_STRING']; } /*跳转到用户登陆页面,指定Login后跳转的URL*/ redirect('auth/login?redirect='.$redirect); } } }
class User extends MY_Controller { function login() { if ($this->tank_auth->is_logged_in()) { // logged in redirect('/'); } else { //other codes here...... /*判断是否有redirect信息*/ $data['redirect'] = isset($_GET['redirect']) ? $_GET['redirect'] : '/'; if ($this->form_validation->run()) { // validation ok if ($this->tank_auth->login( $this->form_validation->set_value('login'), $this->form_validation->set_value('password'), $this->form_validation->set_value('remember'), $data['login_by_username'], $data['login_by_email'])) { // success redirect($data['redirect']); } else { //error handling } } $this->load->view("login_form") } } }
Note: In login_form, please note that the form address for submitting the form is:
<?php echo form_open(site_url("/auth/login?redirect=".$redirect)); ?>
