Little help with sessions - El Forum - 01-11-2010

Hello!
I have in plan to make some kind of CMS for my site which is developed in CI. I am little confused about handling sessions so please tell me if I am doing right thing here;
I am using MY_Controller, and inside of that file I added another class:
Code:
// above is MY_Controller... Admin_Controller, is used to be a 'template' for entire CMS...
class Admin_Controller extends MY_Controller {
function Admin_Controller () {
parent::MY_Controller();
$this->load->library('session');
$this->data['sessionID'] = "";
$this->data['menu'] = "";
$this->data['footer'] = "footer text"; // some custom text
$this->load->view('admin/admin_home', $this->data, TRUE);
}
}My admin controller looks like this:
Code:
<?php
class Admin extends Admin_Controller {
function __construct() {
parent::Admin_Controller();
}
function index() {
$welcome_message = "welcome message"; // just some custom message
$this->load->helper('form', 'url');
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'callback_login_check|trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|md5');
if ($this->form_validation->run() == FALSE) {
$newdata = array('user_logged' => FALSE);
$this->session->set_userdata($newdata);
$this->data['user_logged'] = $this->session->userdata('user_logged');
$this->data['admin_main_view'] = $this->load->view('admin/admin_login', NULL, TRUE);
$this->load->view('admin/admin_home', $this->data);
} else {
$this->data['menu'] = $this->load->view('admin/admin_menu', NULL, TRUE);
$this->data['admin_main_view'] = $welcome_message;
$this->load->view('admin/admin_home', $this->data);
}
}
function login_check($str) {
$user = $this->input->post('username');
$pass = $this->input->post('password');
$query = $this->db->query("SELECT username,password FROM users WHERE username='$user' AND password=md5('$pass')");
if($query->num_rows() == 1) {
$newdata = array('user_logged' => TRUE);
$this->session->set_userdata($newdata);
$this->data['user_logged'] = $this->session->userdata('user_logged');
return TRUE;
} else {
return FALSE;
}
}
}
/* EOF */My admin_home.php file is really simple, basically it looks like this:
Code:
<?php
if ($user_logged == TRUE) {
echo $menu;
}
echo $admin_main_view;
echo $footer;
?>And if I want to load some other page from my menu (let's call it 'news'), I do it like this:
Code:
<?php
class News extends Admin_Controller {
function __construct() {
parent::Admin_Controller();
}
function index() {
if ($this->session->userdata('user_logged') == TRUE){
$this->data['user_logged'] = $this->session->userdata('user_logged');
$this->data['menu'] = $this->load->view('admin/admin_menu', NULL, TRUE);
$this->data['admin_main_view'] = $this->load->view('admin/admin_news', NULL, TRUE);
} else {
$this->data['user_logged'] = $this->session->userdata('user_logged');
$this->data['menu'] = "";
$this->data['admin_main_view'] = $this->load->view('admin/admin_home', NULL, TRUE);
}
$this->load->view('admin/admin_home', $this->data);
}
}
/* EOF */Since I had lots of localized names in my variables there could be a small typo in my examples, but I need to know if I understand the logic correctly here...
I am not sure if I am handling session data correctly??
Thank you very much for any help/tips/advices....!!

If the sessions are working (and doing their job as you intended), then you are managing them well.
As I can see and understand from the code samples, you are handling the session well.

Models are great, use them to help keep your controllers clean and free of maintenance nightmares like queries.
