Question

我正在建立一个paypal立即购买按钮

我显示了购物车商品的总价

购物车是一个自定义的PHP购物车，它使用cookie来存储用户商品数据

但是，我希望paypal付款页面显示我的用户购物车中的商品列表。

我已尝试将cmd从_xclick更改为_cart并添加更多代码行，但是当我测试付款按钮并点击立即购买时，会出现一个paypal页面

检测到错误

您的购物车是空的。

当cmd为_xclick时，购物车内容会传递给PayPal并且我的代码有效，

我做错了什么或错过了什么？除了插入页眉和页脚之外，我对PHP很陌生，所以我对错误或遗漏的内容感到有点迷失

这是我的代码：

paypal付款按钮代码：

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="item_name_1" value="item name 1">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business" value="me@mysite.com">
<input type="hidden" name="item_name" value="Order#21874">
<input type="hidden" name="currency_code" value="GBP">
