    $usernamename = $_GET['usernamename'];
$code = $_GET['code'];
$email = $_GET['email'];
$res = mysql_query("SELECT * FROM `table` WHERE `usernamename` = '$usernamename' AND  `code` = '$code' AND  `email` = '$email'  LIMIT 1 ") or die(mysql_error());
if($row = mysql_fetch_assoc($res))
{
    header("location:index.php");
    exit;
}
