CodeIgniter獨特的功能不起作用

這是我想要做的。我希望我的左菜單基於組。如果我已將權限授予組以查看菜單，則該組應可見。CodeIgniter獨特的功能不起作用

現在在進一步討論細節。我想告訴你我到底做了些什麼，以及在哪裏應用這個特定的菜單組權限。

這是基本控制器在覈心文件夾中命名爲My_Controller.php。

我的Main控制器從My_Controller延伸。

這裏是My_Controller編碼。

<?php 
/** 
* Created by JetBrains PhpStorm. 
* User: SBPS 
* Date: 3/13/13 
* Time: 4:55 PM 
* To change this template use File | Settings | File Templates. 
*/ 

class My_Controller extends CI_Controller{ 
    function __construct(){ 
     parent::__construct(); 
    } 
    public function UserGroups(){ 
     $UserID=1; 
     $this->load->model('ui_components/Left_menu_cpanel'); 
     $Groups=$this->Left_menu_cpanel->get_user_groups($UserID); 
     return $Groups; 
    } 
}

這是我的Main控制器。

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class Main extends My_Controller { 
    /* 
    * Main Controller 
    * Designed By: Kifayat Ullah 
    * Purpose: To work as a main Control Panel for the Authenticated users 
    */ 


    public function index() { 
     if(!$this->session->userdata('UserID') 
     || $this->session->userdata('UserID')<=0){ 
      redirect('user_management/login_form'); 
     }// end of session check 
     // Prepare the LeftHandSide Menu Object and Send it to the View for Display 
     $this->load->model('ui_components/Left_menu_cpanel'); 
     $UserGroups=$this->UserGroups(); 

     // retrive menu List object 


     // Pass the name of the view that you want to load 
     $data['main_container']='tamplet_includes/tamplet_main_container_tags'; 
     $data['UserGroups']=$UserGroups; 
     //$data['UserGroups']=$this->UserGroups(); 
     $this->load->view('SystemView',$data); 

     //var_dump($UserGroups); 
    } 

    function UserAdditionForm(){ 

     echo 'hello'; 
    } 

} 

/* End of file welcome.php */ 
/* Location: ./application/controllers/welcome.php */

現在它的模型轉向。

我的基本模型命名爲My_Model.php在Core Folder中。我的left_menu_cpanel從My_Model.php延伸。

My_Model.php基本模型文件：

<?php 
/** 
* Created by JetBrains PhpStorm. 
* User: SBPS 
* Date: 3/19/13 
* Time: 3:13 PM 
* To change this template use File | Settings | File Templates. 
*/ 

class My_Model extends CI_Model{ 
    function __construct(){ 
     parent::__construct(); 
    } 

    public function get_user_groups($UserID){ 
     //$UserID=1; // We will Update this UserID Later 
     $this->load->helper('security'); 
     $this->db->select('*'); 
     $this->db->from('sys_user_accounts'); 
     $this->db->join('sys_user_groups_memberships', 'sys_user_groups_memberships.UserID = sys_user_accounts.UserID', 'INNER'); 
     $this->db->where('sys_user_accounts.UserID', $UserID); 
     $this->db->join('sys_user_groups', 'sys_user_groups.GroupID = sys_user_groups_memberships.GroupID', 'INNER'); 
     $query = $this->db->get(); 

     return $query->result(); // return all forms list 

    } 
}

left_menu_cpanel.php型號文件：

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class Left_menu_cpanel extends My_Model { 
    function __construct() 
    { 
     parent::__construct(); 
    } 

    // This function returns true if a user authenticaton is successfull 
    public function get_left_menu_items($GroupID){ 
     //$GroupID=1; // We need update this to a Group Array from the users permissions list 
     $this->load->helper('security'); 
     $this->db->distinct(); 
     $this->db->select('*'); 
     $this->db->from('sys_group_roles_forms_view'); 
     $this->db->where('GroupID', $GroupID); 
     $query = $this->db->get(); 

     return $query->result(); // return all forms list  

    }// end of authenticate function 
}//end of class 
/* End of file left_menu_cpanel.php.php */ 
/* Location: ./application/models/user_management/left_menu_cpanel.php.php */ 
?>
