代码签名检查所有功能（选项卡） [英] codeigniter login check for all functions(tabs)

问题描述

我有一个登录控件的功能。如果用户did not登录它重定向到 login.php

i have a function for login controls. if user didnt login it redirects to login.php

在我的控制器我有很多函数，页面。所以我必须在每个函数中调用 $ this-> is_logged_in（）; 函数。

in my controller i have to many functions and this functions represents pages in website. so do i have to call $this->is_logged_in(); function in each function.

例如：

class Admin extends CI_Controller{


        function index(){
            $this->is_logged_in(); // works fine like this
                $this->load->view('admin/welcome_message');
        }

        function users(){
            $this->is_logged_in(); // works fine like this
                $this->load->view('admin/users');
        }

        function comments(){
            $this->is_logged_in(); // works fine like this
                $this->load->view('admin/comments');
        }

}

我不想调用此函数在所有功能。当我调用这个结构中的结果是：无限循环。

i dont want to call this function in all function. when i call this in construct result is: infinite loop.

推荐答案

在你的应用程序/它的构造函数do：

Create your own base controller in your application/core folder and in its constructor do:

class MY_Controller extends CI_Controller {

    public function __construct() 
    {
        parent::__construct();

        // Check that the user is logged in
        if ($this->session->userdata('userid') == null || $this->session->userdata('userid') < 1) {
            // Prevent infinite loop by checking that this isn't the login controller               
            if ($this->router->class != '<Name of Your Login Controller') 
            {                        
                redirect(base_url());
            }
        }   
    }
}

所有的控制器只需要继承你的新控制器，然后所有的请求将检查用户是否登录。

Then all of your controllers just need to inherit your new controller and then all requests will check that the user is logged in.

这可以更具体如果需要也检查 $ this-> router->方法匹配特定操作。

This can be more specific if required by also checking $this->router->method to match against a specific action.
