在codeigniter中未设置会话

Question

我aam实际上不能在codeigniter中注销后重定向到同一页面。但是当我第一次单击注销时，它重定向到同一页面，但会话未被删除...再次发生时我点击注销会议被geeting销毁..可以在这里找到问题。

控制器......在视图文件

时，“注销”点击在会话应该得到破坏，它应该重定向我要的是到没有会话的视图页面

Answer 1

会话类在CI3中已更改，现在session_destroy不会接受任何参数。试试$ this-> session-> sess_destroy（）;

Answer 2

要毁灭你只需要会话：

$this->session->sess_destroy(); 

而且我想你应该尝试这条线之后将用户重定向：

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