codeigniter 中的会话不起作用

Question

会话无法正常工作。登录时，它正在指导 member_area 函数，这是正确的，但如果条件不起作用，则在 member_area 函数中。结果直接进入输出死亡的 member_area 函数的 else 部分。 if条件的member_area函数有错误吗？

这是我的主控制器，即欢迎控制器

 function login()
    {
        $this->form_validation->set_rules('email', 'E-mail', 'valid_email');
        $this->form_validation->set_rules('password', 'Password', 'min_length[5]|max_length[8]');
            if ($this->form_validation->run()==FALSE)
           {
             $data['view']  = 'login_view';
             $this->load->view('load_view',$data);

           }
        else
        {           

                 $email=$_POST['email'];
                 $password = md5($_POST['password']);
                 $this->load->model('Sample_model');
                 $credentials = array(
                                    'email' => $_POST['email'],
                                    'password' => md5($_POST['password'])
                                       );
                  $user = $this->Sample_model->check_user($credentials);
                  if($user->num_rows() == 1)
                  {

                    $user = $user->row();
                   $session = array(
                                 'name' => $user->name,
                                 'is_logged_in' => TRUE
                                  );
                   $this->session->set_userdata($sesson);
                   redirect('welcome/member_area');

                  }

                       else {

                             $data['view'] = 'error_view';
                              $data['msg']  = 'Login failed';
                              $this->load->view('load_view',$data);

                           }


        }

    }
     public function member_area()
    {
       if($this->session->userdata('is_logged_in'))
       {  
        $data['view'] = 'memberarea_view';
        $this->load->view('load_view',$data);
      }

      else  die('die');

     }

I have added session in config/Autoload

$autoload['libraries'] = array('database','session','form_validation');

这是当前登录中使用的模型。 样品模型

<?php
class Sample_model extends CI_Model {

        public function __construct()
        {
                //Call the CI_Model constructor
                parent::__construct();
        }



        public function add_user($user)
        {
            return $this->db->insert('users', $user);
        }
     public function check_user($credentials)
       {
         $this->db->where($credentials);
         return $this->db->get('users');
       }

}

这是 login_view 表单。我正在通过此表单输入电子邮件和密码。

库

$autoload['libraries'] = array('database','session','form_validation');

帮手

$autoload['helper'] = array('url', 'file');

控制器

defined('BASEPATH') OR exit('不允许直接脚本访问');

欢迎类扩展 CI_Controller {

function login()
{

    $this->form_validation->set_rules('email', 'E-mail', 'valid_email');
    $this->form_validation->set_rules('password', 'Password', 'min_length[5]|max_length[8]');
        if ($this->form_validation->run()==FALSE)
       {
         $data['view']  = 'login_view';
         $this->load->view('login_view',$data);

       }
    else
    {           

             $email=$_POST['email'];
             $password = md5($_POST['password']);
             $this->load->model('Sample_model');
             $credentials = array(
                                'email' => $_POST['email'],
                                'password' => md5($_POST['password'])
                                   );
              $user = $this->Sample_model->check_user($credentials);
              if($user->num_rows() == 1)
              {

                $user = $user->row();
               $session = array(
                             'name' => $user->name,
                             'is_logged_in' => TRUE
                              );
               $this->session->set_userdata($session);
               redirect('welcome/member_area');

              }

                   else {

                         $data['view'] = 'error_view';
                          $data['msg']  = 'Login failed';
                          $this->load->view('login_view',$data);

                       }


    }

}



 public function member_area()
{  
   if($this->session->userdata('is_logged_in'))
   {  
    $data['view'] = 'member_view';

    $this->load->view('member_view',$data);
  }
  else{  die('die');
     }

 }

    function logout()
    {
    $newdata = array(
    'name'  =>'',              
    'is_logged_in' => FALSE,
    );

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

    redirect('welcome/login','refresh');
    }

}

型号

类 Sample_model 扩展 CI_Model {

    public function __construct()
    {
            //Call the CI_Model constructor
            parent::__construct();
    }



    public function add_user($user)
    {
        return $this->db->insert('users', $user);
    }
 public function check_user($credentials)
   {
     $this->db->where($credentials);
     return $this->db->get('users');
   }

}
