if(isset($_GET['add'])) {

    $query = query("SELECT * FROM products WHERE product_id=".escape_string($_GET['add'])." ");
    confirm($query);

    while($row = fetch_array($query)) {

        if($row['product_quantity'] != $_SESSION['product_' . $_GET['add']]) {

$_SESSION['product_' . $_GET['add']] +=1;

redirect("../public/checkout.php");
}else{

    set_message("We only have" . $row['product_quantity'] . " " . " available");

    redirect("../public/checkout.php");

if(isset($_GET['remove'])) {

    $_SESSION['product_' . $_GET['remove']]--;

    if($_SESSION['product_' . $_GET['remove']] < 1) {
