问题描述
大约2-3周前，我在网站上添加了PayPal付款处理程序，它的工作原理很不错，没有任何问题.现在，我回到该项目来调整代码.我还没有碰过2-3周前完成的Paypal代码，因此尝试付款.
About 2-3 weeks ago I added PayPal payment processing to my site and it worked like a charm with no problems. Now I've come back to the project to tweak the code. I haven't touched the Paypal code that I finished 2-3 weeks ago, and I tried to pay an invoice.
我目前正在沙箱中运行它.我收到的错误是重复的交易，重复的发票ID.但是，每个发票ID对于创建的每个发票都是唯一的，因此，我什至看不出这可能是个问题(更不用说我没有触摸代码了).下面是使用贝宝连接异常"时遇到的错误的图像.
I am currently running this in sandbox. The error I am getting is a duplicate transaction, duplicate invoice id. However each invoice ID is unique to each invoice created so I don't see how that could even be an issue (let alone I didn't touch the code). Below is an image of the error I am getting while using Paypal Connection Exception.
因此，现在我陷入了困境，完全无法解决该问题.任何帮助，我们将不胜感激.谢谢
So now I'm stuck and completely lost on what I should do to fix this issue. Any help is very appreciated. Thanks
推荐答案
已解决.您不能传递自己的唯一发票ID(为什么是IDK)，我只是使用了uniqid()即可.
Solved. You cannot pass in your own unique invoice ID (idk why), I just used uniqid() and it works.
