後臺腳本錯誤

Question

我的目標是調試IPN或任何腳本在頁面外運行。通常錯誤很容易處理，但是當他們在後臺時很難做到。腳本本身在用戶通過paypal支付時啓動。我無法在該頁面上進行調試。

當您離開您的網站作爲此PayPal示例運行時，您將如何記錄錯誤關閉頁面。 我所TREID到目前爲止..

我添加

ini_set('log_errors', true); ini_set('error_log', dirname(__FILE__).'/ipn_errors.log');

用同一個文件夾中調用ipn_errors.log的頁面我試圖調試文件。

的IPN監聽器是通過任意交易觸發sobeit不完整的，無效等的IPN監聽器本身可以指定什麼應該被處理，無論是記錄錯誤，甚至郵寄錯誤指定的電子郵件地址。我已經實現了ipn處理程序來更新有效事務中的數據庫值
