找不到MY_Controller类 [英] MY_Controller class not found

问题描述

我想解决的主要是当有人想访问管理面板时检查用户会话。我已经创建了MY_Controller类并将其放在库中。

 类MY_Controller扩展了CI_Session {
 
 public $ logged_in = FALSE; 
 
 public function __construct（）{
 parent :: __ construct（）; 
 $ this-> is_logged_in（）; 
} 
 
 public function is_logged_in（）
 {
 $ logged = $ this-> userdata（'user_id'）; 
 $ this-> logged_in =（$ logged）？真假; 
} 
 
 function sessdestroy（）{
 
 $ this-> session-> sess_destroy（）; 
 
} 
 
} 
  

登录页面。我创建了一个重定向到管理面板（信息中心）的按钮，只是为了测试会话检查是否有效。

  CI_Controller {
 
 function __construct（）{
 
 parent :: __ construct（）; 
 
} 
 
 public function index（）{
 
 $ this-> load-> view（'view_login'）; 
 
 if（isset（$ _ POST ['redirect']））{
 
 redirect（'admin'）; 
 
} 
} 
 
 
} 
  

b $ b

这是管理控制器，我检查用户会话是否存在。

  class Admin extends MY_Controller {
 
 function construct（）{
 
 parent :: __ construct（）; 
 
} 
 
 
 function index（）{
 
 if（$ this-> is_logged_in（））{
 
 $ this-> dodadi_destinacija（）; 
 
} 
 
 else redirect（'login'）; 
 
} 
 
} 
  

此错误。

 致命错误：在C：\wamp\www\UserPanel\中找不到类'MY_Controller' application\controllers\admin.php on line 3 
  

你能告诉我你对我的编码的想法解决方案：

解决方案

1. 您需要扩展 CI_Controller class CI_Session


2. 您应该将 MY_Controller 下的应用程序/ core / 文件夹而不是应用程序/库 / ol>
   

   The main thing i want to solve is to check user session when somebody want to access admin panel. I've created MY_Controller class and placed it in library.

   class MY_Controller extends CI_Session {
   
   public $logged_in = FALSE;
   
   public function  __construct() {
       parent::__construct();
       $this->is_logged_in();
   }
   
   public function is_logged_in()
   {
       $logged = $this->userdata('user_id');
       $this->logged_in = ($logged) ? TRUE : FALSE;
   }
   
   function sessdestroy() {
   
       $this->session->sess_destroy();
   
   }
   
   }
   

   This is my login page. I've created a button that redirects to admin panel (dashboard) just to test if the session check works.

   class Login extends CI_Controller {
   
   function __construct() {
   
       parent::__construct();
   
   }
   
   public function index() {
   
       $this->load->view('view_login');
   
       if(isset($_POST['redirect'])) {
   
       redirect('admin');
   
       }
   }
   
   
   }
   

   This is the admin controller where i check if the user session exists.

   class Admin extends MY_Controller {
   
   function construct() {
   
       parent::__construct();
   
   }
   
   
   function index() {
   
       if($this->is_logged_in()) {
   
       $this->dodadi_destinacija();
   
       }
   
       else redirect('login');
   
   }
   
   }
   

   BUT i got this error.

   Fatal error: Class 'MY_Controller' not found in C:\wamp\www\UserPanel\application\controllers\admin.php on line 3
   

   Can you tell me your thoughts about my coding solution for the given problem please :)

   解决方案

   1. You need to extend the CI_Controller class instead of CI_Session
   2. You should place MY_Controller under application/core/ folder instead of application/library
