Symfony2 Paypal Express结账详情

Question

我使用基于payum网站文档的paypal快速结账，我在结账详情方面遇到问题这是我的PaymentController的代码：

class PaymentController extends Controller{

    public function processRequestAction (Request $request) {
        $options = $this->get('doctrine.orm.entity_manager')
            ->getRepository('AdminBundle:Options')->getOption('admin_options');
        $credits = $request->request->get('wizardPayment')['Credits'];
        $total = $credits*$options['credits-rate'];
        $user = $this->get('security.token_storage')->getToken()->getUser();

        $paymentName = 'paypal_express_checkout';

        $storage = $this->get('payum')->getStorage('Magnetomedia\AdminBundle\Entity\PaymentDetails');
        $order = $storage->create();
        $order->setCurrencyCode($options['currency']['code']);
        $order->setTotalAmount($total);
        $order->setDescription('Buy credits from verifyme.email');
        $order->setClientId($user->getId());
        $order->setClientEmail($user->getEmail());

        $order->setDetails(array(
            "SOLUTIONTYPE" => 'Sole',
            "LANDINGPAGE" => 'Billing'
        ));
        $storage->update($order);
        $order->setNumber($order->getId().rand(1,10000));
        $storage->update($order);
        $captureToken = $this->get('payum.security.token_factory')->createCaptureToken(
            $paymentName,
            $order,
            'payment_response' // the route to redirect after capture;
        );

       return $this->redirect($captureToken->getTargetUrl());
    }

        public function paymentResponseAction(Request $request){
            $token = $this->get('payum.security.http_request_verifier')->verify($request);

            $payment = $this->get('payum')->getPayment($token->getPaymentName());

            $entityManager = $this->get('doctrine')->getManager();
            $options = $entityManager->getRepository('AdminBundle:Options')->getOption('admin_options');

            try {
                $payment->execute(new Sync($token));
            } catch (RequestNotSupportedException $e) {}

            $payment->execute($status = new GetHumanStatus($token));

            $refundToken = null;

            if ($status->isCaptured() || $status->isAuthorized()) {
                $refundToken = array(
                    'status' => $status->getValue(),
                    'order' => array(
                        'client' => array(
                            'id' => $status->getFirstModel()->getClientId(),
                            'email' => $status->getFirstModel()->getClientEmail(),
                        ),
                        'number' => $status->getFirstModel()->getNumber(),
                        'description' => $status->getFirstModel()->getCurrencyCode(),
                        'total_amount' => $status->getFirstModel()->getTotalAmount(),
                        'currency_code' => $status->getFirstModel()->getCurrencyCode(),
                        'details' => $status->getFirstModel()->getDetails(),
                    ),
                );
                $user = $entityManager->find('AdminBundle:User',$refundToken['order']['client']['id']);

                $userOrder = new UserOrder();
                $userOrder->setStatus($refundToken['status']);
                $userOrder->setUser($user);
                $userOrder->setDate(new \DateTime());
                $userOrder->setInfo(json_encode($refundToken['order']));
                $entityManager->persist($userOrder);

                $user->addCredits($refundToken['order']['total_amount']/$options['credits-rate']);
                $entityManager->persist($user);
                $this->addFlash(
                    "paymentMessage",
                    'Payment was successfully accepted, you got '
                    .$refundToken['order']['total_amount']/$options['credits-rate'].' Credits'
                );
                $paymentStatus = 'success';
            } elseif(!$status->isCaptured()) {
                $userOrder = new UserOrder();
                $userOrder->setStatus($status->getValue());
                $userOrder->setUser(
                    $entityManager->find('AdminBundle:User',$refundToken['order']['client']['id'])
                );
                $userOrder->setDate(new \DateTime());
                $entityManager->persist($userOrder);

                $paymentStatus ='danger';
                $this->addFlash("paymentMessage",'We are sorry there was an error during the payment process , please try again later or contact us');

            }
            $entityManager->flush();

            return $this->redirectToRoute('profile_page',array('paymentStatus'=>$paymentStatus));
        }
    }

我被重定向到Paypal，但即使我指定了数量和描述，paypal也说“当前购买”＃39;它会列出描述和价格。当我改变这个：

$order->setDetails(array(
                "SOLUTIONTYPE" => 'Sole',
                "LANDINGPAGE" => 'Billing'
            ));

为：

$order->setDetails([
        'L_PAYMENTREQUEST_0_AMT0' => 123,
        'L_PAYMENTREQUEST_0_NAME0' => 'test',
    ]);

它会产生异常：

Myapp \ AdminBundle \ Entity \ User的查询缺少标识符ID     在vendor / doctrine / orm / lib / Doctrine / ORM / ORMException.php第294行

任何想法？
