You can extend the session library by creating a new file MY_Session.php under application/library folder and exending the CI_Session class. Then define your new functions in MY_Session.php.
Here is the code of application/MY_Session.php
Code:
<?php
class MY_Session extends CI_Session
{
public function __construct()
{
parent::__construct();
}
function regenerate_id()
{
// We only update the session every five minutes by default
/*if (($this->userdata['last_activity'] + $this->sess_time_to_update) >= $this->now)
{
return;
}*/
// Save the old session id so we know which record to
// update in the database if we need it
$old_sessid = $this->userdata['session_id'];
$new_sessid = '';
while (strlen($new_sessid) < 32)
{
$new_sessid .= mt_rand(0, mt_getrandmax());
}
// To make the session ID even more secure we'll combine it with the user's IP
$new_sessid .= $this->CI->input->ip_address();
// Turn it into a hash
$new_sessid = md5(uniqid($new_sessid, TRUE));
// Update the session data in the session data array
$this->userdata['session_id'] = $new_sessid;
$this->userdata['last_activity'] = $this->now;
// _set_cookie() will handle this for us if we aren't using database sessions
// by pushing all userdata to the cookie.
$cookie_data = NULL;
// Update the session ID and last_activity field in the DB if needed
if ($this->sess_use_database === TRUE)
{
// set cookie explicitly to only have our session data
$cookie_data = array();
foreach (array('session_id','ip_address','user_agent','last_activity') as $val)
{
$cookie_data[$val] = $this->userdata[$val];
}
$this->CI->db->query($this->CI->db->update_string($this->sess_table_name, array('last_activity' => $this->now, 'session_id' => $new_sessid), array('session_id' => $old_sessid)));
}
// Write the cookie
$this->_set_cookie($cookie_data);
}
}
Call the function through the normal session object like:
Code:
$this->session->regenerate_id();
