嗨，现在大家都试图让这个工作大约 2 天。付款没有问题，但没有更新数据库:(

这是代码：

<?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);
} 
?>

如果您有任何问题只要问我会尝试尽快回答如果你能得到这个工作我会很高兴

谢谢

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";

至： 

// 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)  {

至： 

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

最后，改变： 

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

至： 

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

原因：
PayPal 沙盒配置为拒绝未指定 Host 标头的 HTTP 1.0 请求，因此您当前的脚本将永远无法正确验证。
