I am trying to build a web application with codeigniter. I have installed Ion Auth as my authentication model.
The default Auth.php controller authenticates the user and sets up the session.
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Auth extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->library('ion_auth');
$this->load->library('session');
$this->load->library('form_validation');
$this->load->helper('url');
$data['title']="Login Page";
$this->load->view("view_site_header",$data);
// Load MongoDB library instead of native db driver if required
$this->config->item('use_mongodb', 'ion_auth') ?
$this->load->library('mongo_db') :
$this->load->database();
$this->form_validation->set_error_delimiters($this->config->item('error_start_delimiter', 'ion_auth'), $this->config->item('error_end_delimiter', 'ion_auth'));
}
//redirect if needed, otherwise display the user list
function index()
{
// if not logged in - go to home page
if (!$this->ion_auth->logged_in())
{
//redirect them to the login page
redirect('auth/login', 'refresh');
}
// if user is an admin go to this page
elseif ($this->ion_auth->is_admin())
{
// if an admin, go to admin area
//set the flash data error message if there is one
$this->data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');
//list the users
$this->data['users'] = $this->ion_auth->users()->result();
foreach ($this->data['users'] as $k => $user)
{
$this->data['users'][$k]->groups = $this->ion_auth->get_users_groups($user->id)->result();
}
$this->_render_page('auth/view_users', $this->data);
} else
{
//redirect them to the default home page
$data['title']="IMS Home Page";
$this->load->view("generic/view_site_header",$data);
$this->load->view("generic/view_generic_nav");
$this->load->view("generic/view_content_generic");
$this->load->view("view_site_footer");
}
}
what I want to do is create a new controller for my application logic and leave the auth controller for authentication.
How can I make use of the auth controller to ensure my user is logged in when accessing my new controller? in addition I need the ession information to be available to the new controller.
my new controller, master_data has the following code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Masterdata extends CI_Controller{
function index ()
{
$data['title']="Master Data Home Page";
$this->load->view("master_data/view_master_data_header",$data);
$this->load->view("master_data/view_master_data_nav");
$this->load->view("master_data/view_content_master_data_home");
$this->load->view("master_data/view_master_data_footer");
echo $this->session->userdata('username');
}
}
obviously the echo $this->session->userdata('username');
does not work as the new controller has no knowledge of the auth controller session.
any help appreciated as always.
Kind Regards,
First autoload the ion_auth library. If u simply want to check if the user is logged-in, just check it in every controller's constructor u load
public function __construct() {
parent::__construct();
if (!$this->ion_auth->logged_in()) {
// redirect to login view
}
}
If u happen to have multiple groups , u can create a new controller inside application/core/MY_controller.This controller will check whether user is logged in.You can extend this base controller to create new controller.A very good explanation on this is given by David john.Check this link .
