PayPal не возвращает никаких переменных после успешного процесса транзакции

Question

Я пытаюсь получить значения на странице возврата после успешной транзакции из PayPal. Я уже включил Autoreturn и указал URL-адрес для него. Мои коды работали ранее, он показывал все значения, но он внезапно прекратил работать и просто возвращает пустоту. Пожалуйста, имейте в виду, что я довольно новичок в php.

Вот мои коды:

<form action='https://www.sandbox.paypal.com/cgi-bin/webscr' method='post' > 

        <!-- Identify your business so that you can collect the payments. --> 
        <input type='hidden' name='business' value='business3@eparking.com'> 

        <!-- Specify a Buy Now button. --> 
        <input type='hidden' name='cmd' value='_xclick'> 

        <!-- Specify details about the item that buyers will purchase. --> 
        <input type='hidden' name='item_number' value='". $offenceid ."'> 
        <input type='hidden' name='item_name' value='". $offencetype ."'> 
        <input type='hidden' name='amount' value='". $charge ."'> 
        <input type='hidden' name='currency_code' value='SGD'> 
        <input type='hidden' name='rm' value='2'> 
        <input type='hidden' name='return_url' value='http://mp25.bit-mp.biz/paymentReturn.php'> 


        <!-- Specify the Pages for Successful payment & failed Payment--> 

        <input type='hidden' name='return' value='http://mp25.bit-mp.biz/paymentReturn.php'/> 

        <input type='hidden' name='cancel_return' value='http://mp25.bit-mp.biz/userFines.php'/> 

        <!-- Display the payment button. --> 
        <input type='image' name='submit' src='images/paynow.png' alt='PayPal – The safer, easier way to pay online'> 

        </form> 

paymentReturn.php

// STEP 1: Read POST data 

// reading posted data from directly from $_POST causes serialization 
// issues with array data in POST 
// reading raw POST data from input stream instead. 
$raw_post_data = file_get_contents('php://input'); 
$raw_post_array = explode('&', $raw_post_data); 
$myPost = array(); 
foreach ($raw_post_array as $keyval) { 
    $keyval = explode ('=', $keyval); 
    if (count($keyval) == 2) 
    $myPost[$keyval[0]] = urldecode($keyval[1]); 
} 
// read the post from PayPal system and add 'cmd' 
$req = 'cmd=_notify-validate'; 
if(function_exists('get_magic_quotes_gpc')) { 
    $get_magic_quotes_exists = true; 
} 
foreach ($myPost as $key => $value) {   
    if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) { 
     $value = urlencode(stripslashes($value)); 
    } else { 
     $value = urlencode($value); 
    } 
    $req .= "&$key=$value"; 
} 


// STEP 2: Post IPN data back to paypal to validate 

$ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr'); 
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $req); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); 
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close')); 

// In wamp like environments that do not come bundled with root authority certificates, 
// please download 'cacert.pem' from "http://curl.haxx.se/docs/caextract.html" and set the directory path 
// of the certificate as shown below. 
// curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem'); 
if(!($res = curl_exec($ch))) { 
    // error_log("Got " . curl_error($ch) . " when processing IPN data"); 
    curl_close($ch); 
    exit; 
} 
curl_close($ch); 


// STEP 3: Inspect IPN validation result and act accordingly 

if (strcmp ($res, "VERIFIED") == 0) { 
    // check whether the payment_status is Completed 
    // check that txn_id has not been previously processed 
    // check that receiver_email is your Primary PayPal email 
    // check that payment_amount/payment_currency are correct 
    // process payment 

    // 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']; 

} 
else if (strcmp ($res, "INVALID") == 0) { 
    // log for manual investigation 
} 

Спасибо.

Возможно, вы указали неправильный ответURL на конфигурацию PayPal.

двойная проверка на этом

 <input type='hidden' name='return' value='______'/> 

Кроме того, ваш responseURL должен под тот же домен, который вы регистрируетесь в системе PayPal.
