symfony - 使用 JMSPaymentCoreBundle 和 JMSPaymentPaypalBundle 发送自定义字段

Question

我将 JMSPaymentCoreBundle 与 JMSPaymentPaypalBundle 一起使用，一切正常。但现在我需要向 Paypal 发送自定义字段，IPN 消息确认稍后将其发回给我。

我已尝试将此“自定义”字段作为 ExtendedData 添加到 PaymentInstruction 中，但 Paypal 不会将此自定义字段发回给我。有什么办法吗？准备 PaymentInstruction 时的部分代码:

$router = $this->get('router');

        $extendedData = new ExtendedData();
        $extendedData->set('return_url',$router->generate('payment_complete', array(
                'id' => $orden->getId(),
        ), true));

        $extendedData->set('cancel_url', $router->generate('payment_cancel', array(
                'id' => $orden->getId(),
        ), true));
        $extendedData->set('default_method', 'payment_paypal');
        $extendedData->set('item_name', $orden->getItemName());
        $extendedData->set('item_number', $orden->getId());
        $extendedData->set('custom', 'customvalue');


        $instruction = new PaymentInstruction((float)$orden->getAmount(), $orden->getCurrency(), 'paypal_express_checkout', $extendedData);
        $ppc = $this->get('payment.plugin_controller');
        $ppc->createPaymentInstruction($instruction);

        $orden->setPaymentInstruction($instruction);
        $em->persist($orden);
        $em->flush();

谢谢!

我自己回答:

        $extendedData->set('checkout_params',array(
            'PAYMENTREQUEST_0_CUSTOM' => $orden->getId()));

它可以包含其他参数:L_PAYMENTREQUEST_0_NAME0，L_PAYMENTREQUEST_0_NUMBER0，L_PAYMENTREQUEST_0_DESC0,L_PAYMENTREQUEST_0_AMT0,L_PAYMENTREQUEST_0_QTY0,...
