Question

更新1：

将$res写入文本文件只会返回单词VERIFIED：

<?php  
/*  
mysql_connect("localhost", "user", "password") or die(mysql_error());  
mysql_select_db("PayPal") or die(mysql_error());  
*/

// 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";  

$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);  

if (!$fp) {  
// HTTP ERROR  
} else {  
fputs ($fp, $header . $req);  
while (!feof($fp)) {  
$res = fgets ($fp, 1024);  
if (strcmp ($res, "VERIFIED") == 0) {  

$ourFileName = "payment_successful.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fwrite($ourFileHandle, $res);
fclose($ourFileHandle);


}  

else if (strcmp ($res, "INVALID") == 0) {  

$ourFileName = "payment_failed.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fwrite($ourFileHandle, $res);
fclose($ourFileHandle);

}  
}  
fclose ($fp);  
}  
?>

原始问题：

我有以下IPN（即时付款通知）脚本，该脚本有效，即如果成功则创建成功文件，如果失败则创建失败文件。

paypal是否将帖子值返回到IPN文件，以便我可以确定哪个付款成功或哪个付款失败了？

如果是，我如何访问这些值？

如果不是，我如何确定哪些付款被接受或拒绝？

这是我目前拥有的IPN文件中的脚本：

<?php  
// 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";  

$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);  

if (!$fp) {  
// HTTP ERROR  
} else {  
fputs ($fp, $header . $req);  
while (!feof($fp)) {  
$res = fgets ($fp, 1024);  
if (strcmp ($res, "VERIFIED") == 0) {  

$ourFileName = "payment_successful.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);

}  

else if (strcmp ($res, "INVALID") == 0) {  

$ourFileName = "payment_failed.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);

}  
}  
fclose ($fp);  
}  
?>

Answer 1

您的通用脚本中有答案。

Paypal将在字符串中返回VERIFIED或INVALID字样。

($res, "VERIFIED") == 0

一个好方法是将$ res的值写入您的日志，您将在最后看到返回的结果。

确保您也使用沙箱进行测试。

另外在http://x.com有一个论坛（他们为这个域支付了多少钱？）

FWIW，Paypal的IPN是PITA。

Answer 2

我以这种方式实施了我的

foreach ($_POST as $key => $value)
{
    $data[$key] = $value;
}

做一个echo '<pre>'。print_r（$ data，true）。'</pre>';

会产生这样的东西：

cmd=_notify-validate
test_ipn=1
payment_type=echeck
payment_date=22:21:28 Mar 24, 2011 PDT
payment_status=Completed
address_status=confirmed
