我正在开发一个电子商务网站。我想允许用户使用 Paypal 付款。所以我安装并配置了以下捆绑包：

"jms/security-extra-bundle": "dev-master",
"jms/payment-core-bundle": "master-dev",
"jms/di-extra-bundle": "1.7.0",
"jms/payment-paypal-bundle": "dev-master"

当我点击支付按钮时出现以下错误：

错误：在 null 上调用成员函数 getPendingTransaction()

$instruction = $commande->getPaymentInstruction();
        if (null === $pendingTransaction = $instruction->getPendingTransaction()) {
            $payment = $this->ppc->createPayment($instruction->getId(), $instruction->getAmount() - $instruction->getDepositedAmount());
        } else {
            $payment = $pendingTransaction->getPayment();

这是我的控制器：

    /**
     * @Route("/complete/{id}", name = "payment_complete")
     */
    public function completeAction(Commandes $commande) // id of the order
    {

        $instruction = $commande->getPaymentInstruction();
        if (null === $pendingTransaction = $instruction->getPendingTransaction()) {
            $payment = $this->ppc->createPayment($instruction->getId(), $instruction->getAmount() - $instruction->getDepositedAmount());
        } else {
            $payment = $pendingTransaction->getPayment();
        }

        $result = $this->ppc->approveAndDeposit($payment->getId(), $payment->getTargetAmount());
        if (Result::STATUS_PENDING === $result->getStatus()) {
            $ex = $result->getPluginException();

            if ($ex instanceof ActionRequiredException) {
                $action = $ex->getAction();

                if ($action instanceof VisitUrl) {
                    return new RedirectResponse($action->getUrl());
                }

                throw $ex;
            }
        } else if (Result::STATUS_SUCCESS !== $result->getStatus()) {
            throw new \RuntimeException('Transaction was not successful: ' . $result->getReasonCode());
        }
        // if successfull, i render my order validation template
        return $this->render('FLYBookingsBundle:Post:validation.html.twig', array('commande' => $commande));

    }

    /** @DI\LookupMethod("form.factory") */
    protected function getFormFactory()
    {
    }

    /**
     * @Route("/cancel", name = "payment_cancel")
     */
    public function CancelAction()
    {
        $this->get('session')->getFlashBag()->add('info', 'Transaction annulée.');
        return $this->redirect($this->generateUrl('yourTemplate'));
    }

}

这是我的实体命令：

在不知道这些组件的情况下，您的

$instruction = $commande->getPaymentInstruction();

如果您在 null 上调用该函数，则返回 null 并在下一行中：

$instruction->getPendingTransaction()
