A MY_Session that includes a method to create a session cookie that expires when browse closes.

• Create MY_Session.php in your system\application\libraries folder and paste the following code.

[code] <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); /**

• MY_Session Class

• Extends the core CI_Session giving it the ability to create

• session cookies that expire when the browser closes */ class MY_Session extends CI_Session {

  // ------------------------------------------------------------------------

  /**

  • Cookie Monster eats up the session cookie just before browser closes if he's awake!
  • Okay, fine! It works by creating a cookie that tells CI_Session
  • to create session cookies that expire when the browser closes
  • @access public
  • @return void */ function cookie_monster($asleep) { $asleep ? setcookie($this->sess_cookie_name.'_cm', 'true', 0, $this->cookie_path, $this->cookie_domain, 0) : setcookie($this->sess_cookie_name.'_cm', 'false', 0, $this->cookie_path, $this->cookie_domain, 0); $this->sess_time_to_update = -1; $this->sess_update(); }

  // ------------------------------------------------------------------------

  /**

  • Write the session cookie

  • @return void */ function _set_cookie($cookie_data = NULL) { if (is_null($cookie_data)) { $cookie_data = $this->userdata; }

    // Serialize the userdata for the cookie $cookie_data = $this->_serialize($cookie_data);

    if ($this->sess_encrypt_cookie == TRUE) { $cookie_data = $this->CI->encrypt->encode($cookie_data); } else { // if encryption is not used, we provide an md5 hash to prevent userside tampering $cookie_data = $cookie_data.md5($cookie_data.$this->encryption_key); }

    // Set the cookie setcookie( $this->sess_cookie_name, $cookie_data, // if cookie monster exist and is awake, generate a session cookie that expires on browser close isset($_COOKIE[$this->sess_cookie_name.'_cm']) && $_COOKIE[$this->sess_cookie_name.'_cm'] == 'true' ? 0 : $this->sess_expiration + time(), $this->cookie_path, $this->cookie_domain, 0 ); }
