class Test extends CI_Controller {
var $model;

function __construct() {
  parent::__construct();
  
  // for session library
  $this->load->library( array('session') );
  
  // form helper
  $this->load->helper( array('form','url', 'html', 'string') );
  
  // load the test model
  $this->load->model("test/testmodel");
  
  // initialize the test model
  $this->model = new TestModel();
}


// function name index is a reserved word
function index() {
  // echo "te";  
  if( ! $this->session->userdata('isLogin'))
   $this->load->view("test/login", array('hh', 'laur0n'));
}

function check_login() {
  $username = $this->input->post('username') ? $this->input->post('username') : '' ;
  $password = $this->input->post('password') ? $this->input->post('password') : '' ;
  
  // var_dump( $this->input->post()  );
  $query = $this->model->authenticate_user( $username, $password);
  
  if( $query ) {
   $this->session->set_userdata('isLogin', 'mi agi ko');
   redirect("test/test/loginKo");
   // echo json_encode( $query );
  }
  else {
   // echo json_encode( $query );
   $this->load->view('test/login');
  }
}

function register() {
  $this->load->view("test/register");
}

public function loginKo(){
  
   // if( gettype( $this->session->userdata('isLogin') ) === "boolean" ) redirect('test/test');
   // echo gettype( $this->session->userdata('isLogin') );
   if($this->session->userdata("isLogin")){
  
     $this->load->view('test/information');
   }else{
    redirect("/test/test");
   }
}
  
function save_register() {
  $item = array(
   'objid'    => null,
   'firstname'=> $this->input->post('firstname'),
   'lastname' => $this->input->post('lastname'),
   'email'    => $this->input->post('email'),
   'password' => $this->input->post('password'),
   'gender'   => $this->input->post('gender'),
   'status'   => 'A'
  );
  
  if( $this->model->save_user( $item ))
   $this->load->view('test/login');  
}

function logout() {
  $this->session->sess_destroy();
  // echo json_encode( $this->session->all_userdata() );
  redirect("test/test");
}
}

?>

-->> here is my model

Code:

<?php if( !defined('BASEPATH') ) exit("No direct access script allowed");

class TestModel extends CI_Model {
function __construct() {
  parent::__construct();
  $this->load->database();
}

function save_user( $item ) {
  $query = $this->db->insert('users', $item);
  
  return $query ? 1 : 0;
}

function authenticate_user( $email='', $password='' ) {

  
  $query  = "select * from users where email='{$email}' and password='{$password}'";
  // echo $query;
  $query = $this->db->query( $query );
  
  if( $query->num_rows() > 0 ) {
   return $query->result();
  }
  return false;  
}
}

?>

-->> here is my view

Code:

<?php


if( ! $this->session->userdata('isLogin') )
redirect('test/test');

?>

this is the home page



<?php echo anchor('test/test/logout', 'logout'); ?>

i think you can do that by doing an ajax call to observe your server and then redirect if there is no current session available.

Please use code tags when posting code.

sorry sir,, I'm not familiar with the codeigniter... sorry,,, thank you sir for your response.. i'll edit the one i had posted previously,

@cronix: Sir, just want to ask about the problem of my code, i knew it was a bit buggy. I used a session but i have a problem with that. In pure php, i can handle the session as what i had expected, it couldn't return/access to the home after i logout, though i press the back button in th browser still it was in the login form which is correct. With the session in codeigniter, i have a problem with that because the back button in the browser still can go through the home page though i checked if has a session login or not.
please guide me sir. thank you sir

You are using strings for your isLogin and it should be boolean TRUE/FALSE which is what you are checking for in
your index function. Change your isLogin to TRUE and FALSE.

Code:

function logout()
{
    $this->session->set_userdata('isLogin', FALSE);
    $this->session->sess_destroy();

    // echo json_encode( $this->session->all_userdata() );

    redirect('test/test', 'refresh');
}

Also on all your input->post

Code:

'firstname'=> $this->input->post('firstname', TRUE), // check for xss ( cross site scripting ).

@insiteFX: Thank you for you response sir....I did already what you suggest but still it goes back to the home page when i press back button in the browser. seems that the page was cache,,, i don't know what is the problem with it. ??
