Worldpay 支付网关 - 动态传递数据

Question

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。

我已将所有内容都连接到 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。

我在这里查看了其他几篇关于与 WorldPay 集成的帖子，但似乎没有任何帮助。

我正在本地构建它，所以很遗憾没有任何链接。

我已经看过的页面是： WORLDPAY Integration using php Validating payment amounts with WorldPay

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，我将不胜感激。

提前感谢您的时间和帮助。

Answer 1

整理好了

不确定它是否会在未来适用于任何人，但将线路更改为：

'amount' => $price(),

到

'amount' => $EM_Booking->get_price(),

做得很好！
