ARB过程后XML上的授权点网简单结账方法

Question

如何在授权Dot Net ARB上成功付款后添加第二次Direct Post方法。让我详细说明

假设用户将订阅会员资格，网站也会要求捐赠。在ARB（XML版本）支付会员资格后，我如何通过授权网络网站再次支付一次捐款。我试图使用ARB并且出现重复输入错误。让我在这里粘贴代码以获取更多详细信息。

我使用的ARB代码

        $totatltenure = $CardExpYear-date("Y");

        $start_date = date("Y-m-d");
        $totalOccurrences = 1*$totatltenure;
        $trialOccurrences = 0;
        $trialAmount = 0;
        $expirationDate = $CardExpYear."-".$CardExpMonth;

这是我用过的代码，我曾两次尝试过ARB Script第二次付款，但我觉得这不是正确的过程，所以我得到了Duplicate条目的错误。任何人都可以帮我提供像我使用的ARB XML Curl这样的Direct Post方法的XML CUrl代码。经过大量搜索，我没有找到任何合适的例子。
