How can i prevent the loading of index function with __construct in CodeIgniter?

Question

Hello,

i am building admin area for my app with CodeIgniter, i created a base Admin Controller in the library named: MY_Admin_Base that extends the CI Controller. and there i checking in the DB if the admin has access to the method.

class MY_Admin_Base extends Controller {

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


        //check if the admin has premission to the page
        $this->load->model('admin_permissions_model');
        $query = $this->admin_permissions_model->get_admin_permission(
            array(
            'admin_id'=>$this->session->userdata('admin_id'),
            'page_id'=>$pages_cat_id)
            );

            if(!$query)
                $this->view->load('admin/restricted_area');
    }
}

the main class extends that MY_Admin_Base, and has index method, something like that:

class Main extends MY_Admin_Base {

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

    function index() 
    {       
        $this->view->load('admin/main');
    }
}

the problem is that the both the views are loaded if the admin does`nt have access...the restricted and the main view.

someone have any suggestion?

Answer 1

In the MY_Admin_Base class create a variable to store whether or not the user is an admin:

class MY_Admin_Base extends Controller {
    public $is_admin = true;

Then change

if(!$query)
    $this->view->load('admin/restricted_area');

to

if(!$query) {
    $this->view->load('admin/restricted_area');
    $this->is_admin = false;
}

then in your index function, change the code to.

function index()  {
    if(!$this->is_admin) return;

    $this->view->load('admin/main');
}
