Codeigniter实现处理用户登录验证后的URL跳转
codeigniter处理用户登录验证后url跳转,主要涉及到了my_controller.php页面以及登录验证模块user.php页面,具体代码如下:
my_controller.php页面:
{
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);
}
}
}
user.php页面:
{
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
}
}
$this->load->view("login_form")
}
}
/*
note: 在login_form中需要注意,提交表单的form地址:
<?php echo form_open(site_url("/auth/login?redirect=".$redirect)); ?>
*/
}
在login_form中需要注意,提交表单的form地址为:
