未在codeigniter中設置會話

Question

我aam實際上無法在codeigniter.log中注銷后重定向到同一頁面。但是，當我第一次單擊注銷時，它重定向到同一頁面，但是會話沒有被刪除...比當我單擊注銷時，會話再次被破壞..不能在這里追蹤問題。

控制器...

我想要的是單擊“注銷”時，會話應該被銷毀，並且應該重定向到沒有會話的視圖頁面

Answer 1

會話類在CI3中已更改，現在session_destroy沒有任何參數。 嘗試$ this-> session-> sess_destroy（）;

來源： http : //www.codeigniter.com/user_guide/libraries/sessions.html#destroying-a-session

Answer 2

要銷毀會話，您只需：

$this->session->sess_destroy();

我認為您應該在此行之后嘗試重定向用戶：

$this->session->sess_destroy();
redirect('site/login', 'refresh');
