我正在尝试创建一个与 WorldPay 一起使用的支付网关，所以我基本上是在破解一个 PayPal 网关来实现结果。
我已经将所有东西都连接到 WorldPay 测试页面并正确传递数据，除了一个字段 - 金额。
我需要动态传递金额，但 WorldPay 仅提供硬编码金额的说明。
我在这里看过其他几篇关于与 WorldPay 集成的帖子，但似乎没有任何帮助。
我正在本地构建它，所以不幸的是没有任何链接。
我在这里看过的页面是： WORLDPAY 使用 php 集成 使用 WorldPay 验证支付金额
我认为这是我需要修改以获得所需结果的代码：
如果有人能告诉我我做错了什么，或者指出我正确的方向，我将非常感激。
提前感谢您的时间和帮助。
