html - 将 Paypal 集成到 HTML 页面中

Question

我有一个客户在卖 T 恤。她希望潜在买家能够选择尺码和颜色，并为每个选项提供数量选项。

我找到了一些计算订单总数的代码，但没有数量选项。

我附上了下面的代码。任何人都可以引导我朝着正确的方向前进吗？我对为 PayPal 进行定制还很陌生，但我是一名网页设计师，所以我不是弄清楚事情的初学者。我还附上了她通过电子邮件发送的客户表格的屏幕截图，以显示她想要的样子。

如有任何帮助，我们将不胜感激。谢谢。

对于基本的 HTML 页面，使用 PayPal 自己的按钮向导。只需转到商家服务 -> 添加到购物车按钮。它将允许您自定义按钮以通过下拉列表指定不同的尺寸，甚至可以在将商品添加到购物车时选择数量。您还可以添加一个“查看购物车”按钮，一切都会为您处理。我在最近的一个网站上使用了它。

虽然添加商品和查看购物车会将用户带到 PayPal 页面，但除非他们正在寻找完全集成的网站，否则此选项快速、简单且可靠。此外，PayPal 在跟踪订单页面的来源方面做得很好，因此用户可以轻松返回。
