отправка нескольких продуктов в PayPal с помощью Symfony

Я работаю с пакетом Symfony Payum для отправки заказов в PayPal, и пока он работает нормально с одним продуктом

Предположим, что мой единственный массив продуктов выглядит так

$orderDetails = array(
        'productID' => '10',
        'fname' => 'First Name',
        'lname' => 'Last Name',
        'phone' => '111',
        'clientemail' => '[email protected]',
        'name' => 'Product Name',
        'description' => 'The Product description.',
        'price' => 8.64,
        'currency_symbol' => '$',
        'currency' => 'USD',
        'clientId' => '222',
        'payment_option' => $paymentName


);

Тогда следующий код работает отлично

$storage = $this->get('payum')->getStorage('ClickTeck\featuresBundle\Entity\Orders');
/** @var $paymentDetails Orders */
$paymentDetails = $storage->create();


$paymentDetails->setClientFname($orderDetails['fname']);
$paymentDetails->setClientLname($orderDetails['lname']);
$paymentDetails->setClientPhone($orderDetails['phone']);
$paymentDetails->setClientEmail($orderDetails['clientemail']);
$paymentDetails->setNumber($orderDetails['productID']);
$paymentDetails->setDescription($orderDetails['description']);
$paymentDetails->setCurrencyCode($orderDetails['currency']);
$paymentDetails->setTotalAmount($orderDetails['price']);
$paymentDetails->setClientId($orderDetails['clientId']);
$paymentDetails->setPaymentOption($orderDetails['payment_option']);



$paymentDetails['PAYMENTREQUEST_0_CURRENCYCODE'] = $orderDetails['currency'];
$paymentDetails['PAYMENTREQUEST_0_AMT'] = $orderDetails['price'];
$paymentDetails['NOSHIPPING'] = Api::NOSHIPPING_NOT_DISPLAY_ADDRESS;
$paymentDetails['REQCONFIRMSHIPPING'] = Api::REQCONFIRMSHIPPING_NOT_REQUIRED;
$paymentDetails['L_PAYMENTREQUEST_0_ITEMCATEGORY0'] = Api::PAYMENTREQUEST_ITERMCATEGORY_DIGITAL;
$paymentDetails['L_PAYMENTREQUEST_0_AMT0'] = $orderDetails['price'];
$paymentDetails['L_PAYMENTREQUEST_0_NAME0'] = $orderDetails['name'];
$paymentDetails['L_PAYMENTREQUEST_0_DESC0'] = $orderDetails['description'];
$storage->update($paymentDetails);
$captureToken = $this->getTokenFactory()->createCaptureToken(
    $paymentName,
    $paymentDetails,
    'payment_done'
);
$paymentDetails['INVNUM'] = $paymentDetails->getId();
$storage->update($paymentDetails);
return $this->redirect($captureToken->getTargetUrl());

Однако, если у меня есть несколько продуктов, таких как массив ниже, то как это сделать?

$paymentName = 'paypal';

$orderDetails = array(
    array(
        'productID' => '10',
        'fname' => 'First Name',
        'lname' => 'Last Name',
        'phone' => '111',
        'clientemail' => '[email protected]',
        'name' => 'Product Name',
        'description' => 'The Product description.',
        'price' => 8.64,
        'currency_symbol' => '$',
        'currency' => 'USD',
        'clientId' => '222',
        'payment_option' => $paymentName
    ),
    array(
        'productID' => '10',
        'fname' => 'First Name',
        'lname' => 'Last Name',
        'phone' => '111',
        'clientemail' => '[email protected]',
        'name' => 'Product Name',
        'description' => 'The Product description.',
        'price' => 8.64,
        'currency_symbol' => '$',
        'currency' => 'USD',
        'clientId' => '222',
        'payment_option' => $paymentName
    ),
);
