我已经包含了一个我试图在这里测试的例子，但由于我是paypal的新手，而且我不知道如何调试paypal，沙盒也没有帮助我：（
看起来付款已被处理和接受，我现在要做的就是更新mysql表，在"if($payment_amount==10.00&&$payment_currency=='GBP'){"下方标记的行下方。我已经在phpmyadmin上测试了我的mysql，它就像一个魅力，它只是其他东西可能是错误的在这里:(

答案 0 :(得分：2)
尝试调试，就像我做的那样：
在每个步骤中，将电子邮件（）包含来自paypal（通过邮寄）和其他人的详细信息。记录（自己邮寄）每次成功，错误，它会给你你的问题来源。例如，把
mail("yourmail@mail.com", "PP", $res, "From:support@paypal.com");
宣布变量
之后答案 1 :(得分：0)
site_url是常数吗？
<input type="hidden" name="return" value="<?php echo site_url.'account/' ?>" />
<input type="hidden" name="cancel_return" value="<?php echo site_url.'account/' ?>" />
<input type="hidden" name="notify_url" value="<?php echo site_url.'account/ipn.php' ?>" />
如果不是，你会错过$或a（），如果它是一个函数。
您是否仔细检查过html源格式中是否返回了完整的网址？如果它在浏览器中工作，似乎paypal可能无法获得IPN的正确返回URL。
