Question

我做了paypal IPN但是我的数据库中没有任何东西。这是我的按钮（我让它基于reoccuring）和我的代码，任何人都看到我哪里出错了？任何人都可以帮我解决这个问题

<?php
$conn = mysql_connect('localhost', 'USERNAME', 'PASSWORD');
if(!$conn) { die("Could not connect: ".mysql_error()); }

$database = mysql_select_db('fbkidsonlinedb', $conn);
if(!$database) { die("Can't use database: ".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";
}

// If testing on Sandbox use: 
$header .= "Host: <!-- w --><a class="postlink" href="http://www.sandbox.paypal.com:443">www.sandbox.paypal.com:443</a><!-- w -->\r\n";
//$header .= "Host: <!-- w --><a class="postlink" href="http://www.paypal.com:443">www.paypal.com:443</a><!-- w -->\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

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

// assign posted variables to local variables
$item_name = $_POST["item_name"];
$item_number = $_POST["item_number"];
$payment_status = $_POST["payment_status"];
$payment_amount = $_POST["mc_gross"];
$payment_currency = $_POST["mc_currency"];
$txn_id = $_POST["txn_id"];
$receiver_email = $_POST["receiver_email"];
$payer_email = $_POST["payer_email"];
$user_id = mysql_real_escape_string($_POST["custom"]);

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') {
                $txn_id_check = mysql_query("SELECT txn_id FROM log WHERE txn_id =".$txn_id."");
                if (mysql_num_rows($txn_id_check) !=1) {
                    if ($payment_amount=='29.95' && $payment_currency=='USD') {
                        $log_query = mysql_query("INSERT INTO log VALUES ('', '".$txn_id."', '".$payer_email."')");
                        $update_premium = mysql_query("UPDATE users SET authLevel='1' where fbID='".$user_id."'");
                    }
                }
            }
        }
        else if (strcmp ($res, "INVALID") == 0) {
            // log for manual investigation
        }
    }
    fclose ($fp);

为什么要为主持人分配链接：

$header .= "Host: <!-- w --><a class="postlink" href="http://www.sandbox.paypal.com:443">www.sandbox.paypal.com:443</a><!-- w -->\r\n";

我认为应该是：

$header .= "Host:http://www.sandbox.paypal.com:443\r\n";

无论如何不太熟悉PayPal，如果这是我的错误就很抱歉
