如何销毁会话与浏览器关闭在codeigniter

问题描述：

最近我开发了一个带codeigniter的web应用程序。

Recently I have developed a web application with codeigniter. I am facing a session related problem there badly.

我使用以下会话配置： / p>

I used the following configuration for session:

$config['sess_cookie_name']     = 'ci_session';
$config['sess_expiration']      = 1800;
$config['sess_expire_on_close'] = FALSE;
$config['sess_encrypt_cookie']  = FALSE;
$config['sess_use_database']    = FALSE;
$config['sess_table_name']      = 'ci_sessions';
$config['sess_match_ip']        = FALSE;
$config['sess_match_useragent'] = TRUE;
$config['sess_time_to_update']  = 300;

现在我的问题是如何通过关闭codeigniter中的浏览器或浏览器标签来销毁所有的会话？

Now my question is how can i destroy all the session with closing browser or browser tab in codeigniter?

答

您可以使用javascript和asynchron请求。
当关闭窗口时，调用window.onunload的处理程序

You can use javascript and asynchron request. When you close the window, the handler of window.onunload is called

var unloadHandler = function(e){
        //here ajax request to close session
  };
window.unload = unloadHandler;

为了解决重定向的问题，php端可以使用计数器

To solve the problem of redirection, php side you can use a counter

  class someController  extends Controller {

   public function methodWithRedirection(){

        $this->session->set_userdata('isRedirection', 1);
        //here you can redirect  
   }
}
class homeController extends Controller{
   public function closeConnection(){
        $this->load->library('session');
        if($this->session->userdata('isRedirection')!== 1){
            //destroy session
         }
      }
   }
