CodeIgniter Processing User login authentication after the URL jump, mainly involved in the my_controller.php page and login Verification Module user.php page, the specific code is as follows:

my_controller.php page:

Copy Code code as follows:

Class My_controller extends Ci_controller
{
Public Function __construct ()
{
Parent::__construct ();
/* To determine whether to log in, to determine whether the current URL is 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 '];
}
/* Jump to the User landing page, specify login after the jump url*/
Redirect (' auth/login?redirect= '. $redirect);
}
}
}

Copy Code code as follows:

Class User extends My_controller
{
function Login ()
{

if ($this->tank_auth->is_logged_in ()) {//logged in
Redirect ('/');

} else {
Other codes ...
* To determine whether there is redirect information * *
$data [' redirect '] = Isset ($_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 {
