php - Paypal standard buttons not returning transaction variables

Question

I'm using PayPal standard buttons in the sandbox environment, but it's driving me bad, I'm using the return custom variable with the rm set to 2, so PayPal should return back to my return URL along with a $_POST array populated with the transaction info, what happens is that it return to my return URL but with an empty $_POST !! What is really driving me mad is that sometimes return with a populated $_POST array, for the same scenario !!! Why is that happening?

您是否在帐户中启用了 Auto 和 PDT？如果您启用了 PDT，请将其关闭。您是否也尝试在帐户中禁用自动退货的情况下进行测试？试试这两个，看看你是否得到返回的数据。
