php - 在数据库中存储 Paypal 详细信息

Question

我正在制作一个用于在线购物的示例网站，但我被困在这里。当我将所有详细信息插入数据库时​​，itemname 和 order_id 未成功插入，其余字段工作正常。

这是表单的代码:

<form method="post" action="https://www.sandbox.paypal.com/cgi-bin/webscr">
                <input type="hidden" name="cmd" value="_xclick">
                <input type="hidden" name="add" value="1">
                <input type="hidden" name="business" value="example@gmail.com">
                <input type="hidden" name="item_name" value="<?php echo  $_SESSION['itemname'];?>">
                <input type="hidden" name="item_number" value="<?php echo $_SESSION['itemnum'];?>">
                <input type="hidden" name="amount" value="1">
                <input type="hidden" name="shipping" value="0">
                <input type="hidden" name="shipping2" value="0">
                <input type="hidden" name="handling" value="0">
                <input type="hidden" name="currency_code" value="USD">
                <input type="hidden" name="return" value="example.com">
                <input type="hidden" name="notify_url" value="example.com" />
                <input type="hidden" name="quantity" value="1">
                <input type="submit" style="margin-top:10px; background:url(images/btn_bg1.png); color:#FFFFFF;"  border="0" name="addtocart" value="Download@ 1$" width="87" height="23" alt="Make payments with PayPal - it's fast, free and secure!">
                </form>

下面的代码用于将详细信息存储在数据库中。

custom在 php 数据库中未在您的表单中声明添加此行 <input type="hidden" name="custom" value="yourvalue"> .确保你的 $_SESSION['itemname'];有效。
