如何在同一表單中使用Paypal IPN通知和notify_url？

Question

我正在使用這種貝寶形式（付款是好的）的訂閱計劃，並沒有得到任何IPN通知，但是當我使用paypal生成的標準貝寶形式一切都與IPN通知是好的。有沒有辦法用這種形式獲得IPN？謝謝

這是我的表格。如果我從這個表單中刪除notify_url，我只能獲取notify_url或IPM上的數據。

PS>主要問題！有沒有辦法使用ipn + notify_url？例？

PS>主要的問題！有沒有辦法使用ipn + notify_url？ 示例？

簡而言之：沒有

可你想要的結果可以實現嗎？ 是的

這一直困擾着貝寶多年的事情，仍然如此。

有一種非常流行的方法（對於那些知道）來解決這個使用PHP和捲曲，並由Codeseekah分發。 （不附屬）

概念

一個單一的IPN的網址是設置貝寶通知您 支付的應用。 IPN處理程序代碼將PayPal的有效載荷廣播到您可能有選擇性地或批量使用的其他IP地址 。

• 多寶IPN的URL現在可以
• 無需更改任何IPN代碼，除非它通過IP過濾請求
• 可以集中IP過濾到廣播IPN，這意味着更容易維護時，PayPal的IP範圍變化
• 可以集中記錄
• 可以排隊和轉播如果衛星（所有其他IPN的網址）都無法訪問

守則

這IPN廣播代碼是在PHP，但概念是不特定語言。只需簡單地移植代碼，它就可以做得很好，甚至更好。

<?php 
    /* 
    * This is a PayPal IPN (Instant Payment Notification) broadcaster 
    * Since PayPal does not provide any straightforward way to add 
    * multiple IPN listeners we'll have to create a central IPN 
    * listener that will broadcast (or filter and dispatch) Instant 
    * Payment Notifications to different destinations (IPN listeners) 
    * 
    * Destination IPN listeners must not panic and recognize IPNs sent 
    * by this central broadcast as valid ones in terms of source IP 
    * and any other fingerprints. Any IP filtering must add this host, 
    * other adjustments made as necessary. 
    * 
    * IPNs are logged into files for debugging and maintenance purposes
