I am a newbie in codeigniter. I am using an an login form to login as an admin. When the admin logs in with the correct user name and password s/he is directed to the home page with a session variable.and then if he clicks the log out button the session is supposed to be destroyed and redirect the user to log in page i.e log in form page. The 1st controller is admin: <pre><code><?php class Admin extends CI_Controller { function index() { $data['main_content'] = 'admin/log_in'; $this -> load -> view('includes/admin/admin_template', $data); } function log_in() { $this->load->model('admin_model'); $query = $this -> admin_model -> validate(); if ($query)// if the user's credentials validated... { $data = array('user_name' => $this -> input -> post('user_name'), 'is_logged_in' => true); $this -> session -> set_userdata($data); redirect('admin/home/admin_home'); } else// incorrect username or password { $this -> index(); } } function log_out() { $this->session->sess_destroy(); redirect('/admin/admin','refresh'); } } </code></pre> The second controller is the home controller: <pre><code><?php class Home extends CI_Controller { function __construct() { parent:: __construct(); $this->is_logged_in(); } function is_logged_in() { $is_logged_in = $this -> session -> userdata('is_logged_in'); if (!isset($is_logged_in) || $is_logged_in != true) { $this -> load -> view('admin/forbidden'); } } function admin_home() { $data['main_content'] = 'home_view'; $this->load->view('admin/home_view'); } } </code></pre> The model is admin_model: <pre><code><?php class Admin_model extends CI_Model { function __construct() { parent:: __construct(); } function validate() { $this->db->where('user_name',$this->input->post('user_name')); $this->db->where('password', $this->input->post('password')); $query = $this->db->get('user'); if($query->num_rows==1) { return true; } } } </code></pre> Now, it supposed the user to logout and destroy the session, but if I click the back button of my browser I can get page back which was supposed not to be and the session is not destroyed. please tell me what I am doing wrong here. I am using codeigniter 2.1.0.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
