codeigniter 检查每个控制器中的用户会话 [英] codeigniter check for user session in every controller

问题描述

我在我的一个控制器中有这个私人会话，用于检查用户是否登录:

I have this private session in one of my controllers that checks if a user is logged in:

function _is_logged_in() {

   $user = $this->session->userdata('user_data');

   if (!isset($user)) { 
      return false; 
   } 
   else { 
      return true;
   }

}

问题是我有不止一个控制器.如何在其他控制器中使用此功能?在每个控制器中重新定义函数并不是很枯燥".

Problem is that I have more than one Controller. How can I use this function in those other controllers? Redefining the function in every Controller isn't very 'DRY'.

有什么想法吗?

推荐答案

另一种选择是创建一个基本控制器.将函数放在基本控制器中，然后从这里继承.

Another option is to create a base controller. Place the function in the base controller and then inherit from this.

要在 CodeIgniter 中实现此目的，请在应用程序的库文件夹中创建一个名为 MY_Controller.php 的文件.

To achieve this in CodeIgniter, create a file called MY_Controller.php in the libraries folder of your application.

class MY_Controller extends Controller
{
    public function __construct()
    {
        parent::__construct();
    }

    public function is_logged_in()
    {
        $user = $this->session->userdata('user_data');
        return isset($user);
    }
}

然后让你的控制器从这个基本控制器继承.

Then make your controller inherit from this base controller.

class X extends MY_Controller
{
    public function __construct()
    {
        parent::__construct();
    }

    public function do_something()
    {
        if ($this->is_logged_in())
        {
            // User is logged in.  Do something.
        }
    }
}
