贝宝噩梦

Question

我已经包含了一个我试图在这里测试的示例，但由于我是 PayPal 的新手，而且我不知道如何调试 PayPal，沙箱对我也没有多大帮助:(

看起来付款已被处理并接受，我现在要做的就是更新 mysql 表，在下面标记的行上，就在 "if($ payment_amount == 10.00&& $ payment_currency =='GBP'){" 下。测试了我的phpmyadmin 上的 mysql 工作起来就像一个魅力，只是这里可能有其他问题:(

Paypal 按钮

Paypal IPN 处理程序

<?php 
// UPDATED LINE BELOW
mail("[myemail]", "PP",'initiated', "From:[email protected]"); 
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value) {
    $value = urlencode(stripslashes($value));
    $req .= "&$key=$value";
}

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

Answer 1

尝试调试，就像我所做的那样：

在每个步骤中，将 email() 与来自 paypal（通过邮寄）和其他人的详细信息放在一起。记录（邮寄给自己）每个成功、错误，它会给您问题根源。例如，

 mail("[email protected]", "PP", $res, "From:[email protected]"); 

在声明变量之后放置

Answer 2

site_url 是常量吗？

<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，则缺少 $ 或 () （如果它是函数）。

您是否仔细检查过完整的 url 是否以 html 源形式返回？如果它在浏览器中工作，则 PayPal 似乎可能无法获取 IPN 的正确返回 URL。
