Question

I have define this controller to check user session:

class SessionController extends CI_Controller {

function __construct()
{
    parent::__construct();
    $this->is_logged_in();      
}

function dashboard_area(){
    $data['main_content'] = 'dashboardView';
    $this->load->view('dashboardTemplate/template', $data);         
}

function is_logged_in()
{
    $is_logged_in = $this->session->userdata('is_logged_in');
    if(!isset($is_logged_in) || $is_logged_in != true)
    {
        echo 'You don\'t have permission to access this page.';
        die();
        //$this->load->view('login_form');
    }
}       
    } ?>

and in my login controller I do this..

   class LoginController extends CI_Controller {

 function index(){      
    $new['main_content'] = 'loginView';
    $this->load->view('loginTemplate/template', $new);          
}   

function verifyUser(){      
    //getting parameters from view 
    $data = array(
            'username' => $this->input->post('username'),
            'password' => $this->input->post('password')
    );


    $this->load->model('loginModel'); 
    $query = $this->loginModel->validate($data);

          if ($query){             //if the user c validated
        //data variable is created becx we want to put username in session
            $data = array(
                'username' => $this->input->post('username'),
                 'is_logged_in' => true 
            );

         $this->session->set_userdata($data);
         redirect('sessionController/dashboard_area');
    }
    else
     {
        $this->index();
    }
}
function logout()
{
    $this->session->sess_destroy();
    $this->index();
}
}   
?>

now the problem is I have many controllers how to I use this .. I don’t want to make new session controllers again and again … and if there is any more good for handling sessions in more then one controller then please let me know ..
iIhave seen this answer also … but after applying the answer no 14 .. it gives me this error

Fatal error: Class 'MY_Controller' not found in C:\xampp\htdocs\StockManagmentSystem\application\controllers\categoryController.php on line 4

I am working in a latest code igniter

Answer 1

Create a MY_Controller in the application/core folder which extends CI_Controller. Place your session functions in the MY_Controller file and then have the rest of your controllers extend MY_Controller instead of CI_Controller.
