Cookie logged in time

[Wipeout]

I have been trying to put a setcookie into my session class and i can't work it out. i want the user to login and the cookie will keep the user logged in for 2 weeks which is time()+1209600

 

If anyone can add it for me i will be most grateful

heres my code:

 

<?php
mysql_connect("$dbserver","$dbuser","$dbpass") or die(mysql_error());
mysql_select_db($dbdata) or die(mysql_error());

$d=$_GET[d]; if($d=="") $d=$_POST[d];
$s=$_GET[s]; if($s=="") $s=$_POST[s];
$u=$_GET[u]; if($u=="") $u=$_POST[u];

session_name("cls"); session_start();

if($_SESSION[user]!="") $user=$_SESSION[user];
if($_SESSION[pass]!="") $pass=$_SESSION[pass];
if($_POST[user]!="") $user=$_POST[user];
if($_POST[pass]!="") $pass=$_POST[pass];
$encrypt_pass=md5($pass);


if($user!="" && $pass!="" && $d!="logout") {
$mdc = mysql_query("SELECT * FROM user WHERE user = '".addslashes($user)."' AND pass = '".addslashes($encrypt_pass)."'"); $usrd = mysql_fetch_array($mdc);
if($usrd[id]!="") {
$_SESSION[user] = $user; $_SESSION[pass] = $encrypt_pass; $lg="ok"; 
mysql_query("UPDATE user SET online='".time()."' WHERE id='".$usrd[id]."'");


} else { session_unset(); $lg="";  }
} else { session_unset(); $lg="";  }

?>
