Question

我无法弄清楚如何在会员中更新Premium。当用户付款并且付款已经过去时，我想将Premium更新为YES

付款完成后，什么都不会发生，如果我的用户有高级访问权限，它仍然会显示NO。

这里有什么想法吗？我使用Paypal IPN

这是我的listener.php

<?php require('includes/config.php'); 



header('HTTP/1.1 200 OK');

//
// STEP 2 - create the response we need to send back to PayPal for them to confirm that it's legit
//

$resp = 'cmd=_notify-validate';
foreach ($_POST as $parm => $var) 
    {
    $var = urlencode(stripslashes($var));
    $resp .= "&$parm=$var";
    }

// STEP 3 - Extract the data PayPal IPN has sent us, into 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'];
  $record_id        = $_POST['custom'];


// Right.. we've pre-pended "cmd=_notify-validate" to the same data that PayPal sent us (I've just shown some of the data PayPal gives us. A complete list
// is on their developer site.  Now we need to send it back to PayPal via HTTP.  To do that, we create a file with the right HTTP headers followed by 
// the data block we just createdand then send the whole bally lot back to PayPal using fsockopen


// STEP 4 - Get the HTTP header into a variable and send back the data we received so that PayPal can confirm it's genuine

$httphead = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$httphead .= "Content-Type: application/x-www-form-urlencoded\r\n";
$httphead .= "Content-Length: " . strlen($resp) . "\r\n\r\n";

 // Now create a ="file handle" for writing to a URL to paypal.com on Port 443 (the IPN port)

$errno ='';
$errstr='';

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

// STEP 5 - Nearly done.  Now send the data back to PayPal so it can tell us if the IPN notification was genuine

 if (!$fh) {

// Uh oh. This means that we have not been able to get thru to the PayPal server.  It's an HTTP failure
//
// You need to handle this here according to your preferred business logic.  An email, a log message, a trip to the pub..
           } 

// Connection opened, so spit back the response and get PayPal's view whether it was an authentic notification         

else    {
           fputs ($fh, $httphead . $resp);
           while (!feof($fh))
                {
                $readresp = fgets ($fh, 1024);
                if (strcmp ($readresp, "VERIFIED") == 0) 
                    {





    $stmt = $db->prepare("UPDATE members SET Premium = 'YES' WHERE memberID = :memberID");
$stmt->execute(array(
        ':memberID' => $memberID

    ));


}







}

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

//              Man alive!  A hacking attempt?

                    }
                }
fclose ($fh);
        }
//
//
// STEP 6 - Pour yourself a cold one.
//
//

我现在已经挣扎了一段时间，但我仍然无法让它发挥作用。谢谢你的帮助!!

记住PayPal IPN无法在本地计算机上运行您可以使用PayPal模拟器对其进行验证，您必须通过“notify_url”或将IPN处理程序URL设置到您的PayPal帐户中。以下是我希望它可以帮助您的示例代码。

    $url_parsed = parse_url($paypal_url);
    $post_string = '';
    foreach ($_REQUEST as $field => $value) {
        $post_string .= $field . '=' . urlencode(stripslashes($value)) . '&';
    }
    $post_string.="cmd=_notify-validate"; // append ipn command
    // get the correct paypal url to post request to
    $paypal_mode_status = $ipn_data; //get_option('im_sabdbox_mode');
    if ($paypal_mode_status == true)
    $fp = fsockopen('ssl://www.sandbox.paypal.com', "443", $err_num, $err_str, 60);
    else
    $fp = fsockopen('ssl://www.paypal.com', "443", $err_num, $err_str, 60);
    $ipn_response = '';

    if (!$fp) {
    // could not open the connection. If loggin is on, the error message
    // will be in the log.
        $ipn_status = "fsockopen error no. $err_num: $err_str";
        if ($ipn_data == true) {
        echo 'fsockopen fail';
        }
        return false;
    } else {
    // Post the data back to paypal
        fputs($fp, "POST $url_parsed[path] HTTP/1.1\r\n");
        fputs($fp, "Host: $url_parsed[host]\r\n");
        fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
        fputs($fp, "Content-length: " . strlen($post_string) . "\r\n");
        fputs($fp, "Connection: close\r\n\r\n");
        fputs($fp, $post_string . "\r\n\r\n");

        // loop through the response from the server and append to variable
        while (!feof($fp)) {
        $ipn_response .= fgets($fp, 1024);
        }
        fclose($fp); // close connection
    }
    // Invalid IPN transaction. Check the $ipn_status and log for details.
    if (!preg_match("/VERIFIED/s", $ipn_response)) {
        $ipn_status = 'IPN Validation Failed';

        if ($ipn_data == true) {
        echo 'Validation fail';
        print_r($_REQUEST);
        }
        return false;
    } else {
        $ipn_status = "IPN VERIFIED";
        if ($ipn_data == true) {
        echo 'SUCCESS';
        }
        return true;
    }
