I have been toying around for weeks on the best solution on how to check for session data before allowing the user to access admin sections of their website.
Today I played around with creating a helper function that will do just that.
Helper File (session_helper.php)
<?php
//Function returns the CI instance
//================================
//Usage:
//================================
//ci_instance()->uri->segment(3);
//================================
//Replaces:
//================================
//$ci =& get_instance();
//================================
if(!function_exists('ci_instance')) {
function ci_instance() {
return get_instance();
}
}
if(!function_exists('check_sessions')) {
function check_sessions($session_name) {
if(is_array($session_name)) {
foreach($session_name as $s) {
a($s);
}
} else {
a($session_name);
}
}
}
if(!function_exists('a')) {
function a($session_name) {
if(ci_instance()->session->userdata($session_name)) {
return true;
} else {
redirect('/');
}
}
}
/* End of file session_helper.php */
/* Location: /application/helpers/session_helper.php */
Controller (admin_panel.php)
<?php
Class Admin_panel extends Controller {
function Admin_panel() {
parent::Controller();
//check one session data
check_sessions('username');
//check multiple session data
check_sessions(array('username', 'id'));
}
function index() {
$this->load->view('admin_panel_view');
}
}
/* End of file admin_panel.php */
/* Location: /application/controllers/admin_panel.php */
Take note that I am auto loading my helper file in autoload.php
Hope this helps!
