从网上找了个购物车，挺好用的，简单方便，可就是存在一个问题：不兼容IE6/IE7，点击“添加购物车”按钮没反应，而内网又存在大量的IE6，我看了一下，应该是html的兼容性问题，但就是找不到问题出在哪，大家帮忙看看：

购物车主程序：cart.php：

                        //current URL of the Page. cart_update.php redirects back to this URL

            $results = $db->query("SELECT * FROM cart ORDER BY id ASC");
            if ($results) {

                //fetch results set as object and output HTML
                while($obj = $db->fetch_object($results))

提交按钮的链接，点按钮没反应。cart_update.php：

    $return_url = base64_decode($_GET["return_url"]); //return url

}

//add item in shopping cart

    //limit quantity for single product
    if($product_qty > 10){
        die('
