Hi i have set the cookie for my project... I am using the PHP session library.. First we have to include the PHP session library....

set the cookie

login page controller:

Code:

$this->phpsession->save('u_member','1');
setcookie('u_member','1',0,'/');

Header page view :

Code:

if( isset($_COOKIE['u_member']) && $_COOKIE['u_member'] == '1' )
{
  if($this->phpsession->get('u_member'))
  {
        Your Code Here.......
  }
}
elseif($this->phpsession->get('u_member')!='0')
{
    $this->phpsession->save('session_msg',"Your session has expired. Please login again.");
    redirect('logout');
}

Logout Controller:

Code:

// Checking Session
$session_msg = $this->phpsession->get('session_msg');
setcookie('u_member','',0,'/');
if(!empty($session_msg))
{
echo  $session_msg;
