PayPal IPN 帮助(不是更新数据库)

Question

大家好，大家已经尝试让这个工作大约 2 天了。付款没有问题，但它没有更新数据库:(

代码如下:

<?php

require_once(WWW_DIR."/lib/users.php");


            // Connect to database
$con = mysql_connect("localhost","root","******");
if (!$con)
  {
  die('Could not connect: ' . 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, $errstr, 30); // Test
//$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30); // Live
// assign posted variables to local variables
$item_name = $_POST['item_name'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$txn_id = $_POST['txn_id'];
$payer_email = $_POST['payer_email'];
$name = $_POST['first_name'] . " " . $_POST['last_name'];
$address_street = $_POST['address_street'];
$address_zip = $_POST['address_zip'];
$address_city = $_POST['address_city'];
$contact_phone = $_POST['contact_phone'];
$email = $_POST['payer_email'];
$uid = $users->currentUserId();
//timezone set
date_default_timezone_set('Europe/London');

if (!$fp)
{
    // HTTP ERROR
} else
{
    fputs($fp, $header . $req);
    while (!feof($fp))
    {
        $res = fgets($fp, 1024);
        if (strcmp($res, "VERIFIED") == 0)  {
if($payment_status != "Completed"){
                if($payment_amount == 2.00)
                {
                    $role = 6;
                }
                else
                if($payment_amount == 5.00)
                {
                    $role = 8;
                }
                else
                if($payment_amount == 8.00)
                {
                    $role = 9;
                }

                //update user records
$sql = sprintf("UPDATE users SET role = %d WHERE ID = %d", $role, $uid);
mysql_query($sql);  


 //log payment
            //mysql_query("INSERT INTO payments (email, item_name, payment_status, txn_id, payment_ammount) VALUES('" . mysql_escape_string($email) . "', '" . $item_name . "', '" . $payment_status . "', '" . $txn_id . "', '" . $payment_amount . "' ) ") or die(mysql_error());
      }} else
            if (strcmp($res, "INVALID") == 0)
            {
                // log for manual investigation
            }
    }
    fclose($fp);
} 
?>

如果你有任何问题尽管问我会尽快回答如果你能使这个工作我会很高兴

改变:

// 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";

收件人:

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.1\r\n";
$header .= "Host: www.sandbox.paypal.com\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n";
$header .= "Connection: close\r\n\r\n";

改变:

if (strcmp($res, "VERIFIED") == 0)  {

收件人:

if (strcmp(trim($res), "VERIFIED") == 0)  {

最后，更改:

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

收件人:

if (strcmp(trim($res), "INVALID") == 0)

原因:
PayPal 沙箱配置为拒绝未指定主机 header 的 HTTP 1.0 请求，因此您当前的脚本永远无法正确验证。
