Php CodeIgniter登录会话未销毁

我在登录会话中遇到问题

这就是我迄今为止所尝试的：

User.php控制器

public function index()
{
  if(($this->session->userdata('logged_in') == TRUE))
  {
    if(($this->session->userdata('username') != "" ))
    {
        $this->welcome();
    }
  }
    else {
        $data['title']= 'Home';
        $this->load->view('include/header',$data);
        $this->load->view("frontpage", $data);
        $this->load->view('include/footer',$data);
      }
}

我想你试试这个

public function logout()
{
    $newdata = array(
      //'user_id'   =>'',
      'username'  =>'',
      'logged_in' => ''
     ); 

    $this->session->unset_userdata($newdata);
    $this->session->sess_destroy();
    $this->index(); 
} 

索引函数User.php controller

public function index()
{
  if(($this->session->userdata('logged_in') == TRUE))
  {
    if(($this->session->userdata('username') != "" ))
    {
        $this->welcome();
    }
  }
    else {
        $data['title']= 'Home';
        $this->load->view('include/header',$data);
        $this->load->view("frontpage", $data);
        $this->load->view('include/footer',$data);
      }
}

欢迎活动

public function welcome()
{
  if(($this->session->userdata('logged_in') == TRUE))
  {
    if(($this->session->userdata('username') != "" ))
    {
        $data['title']= 'Welcome';
        $this->load->view('include/header',$data);
        $this->load->view('include/navbar',$data);
        $this->load->view('welcome_view', $data);
        $this->load->view('include/sidebar',$data);
        $this->load->view('include/footer',$data);
    }
  }
  else
  {
      $this->index();
  }  
}

当您注销后返回欢迎页面时，您是否能够访问仅应由登录用户访问的内容？您是否有显示欢迎视图的欢迎控制器？@plainjane我没有欢迎控制器类。当我注销后返回欢迎页面时，我仍然可以访问。如何加载欢迎页面我的意思是从哪个控制器…请在你的问题中发布它我正在加载我的控制器：公共功能索引{//if$this->session->userdata'logged_in'==TRUE if$this->session->userdata'username'！={$this->welcome；}其他{$data['title']='Home'；$this->load->view'include/header'，$data；$this->load->viewfrontpage，$data；$this->load->view'include/footer'，$data；}没有显示任何内容：您新更新的帖子已经显示了我的视图，但我注销后仍然可以返回欢迎页面。
