Symfony 2.2 表单不绑定请求

Question

我的控制器代码是

public function checkoutAction(Request $request) {
        $securityContext = $this->container->get('security.context');
        $request = $this->getRequest();
        $form = $this->createForm(new RequestRunnerType() );
        $data = array();

        if ($request->getMethod() == 'POST') {
            $orderService = $this->container->get('order_service');
            $paymentMethod = $request->request->get('paymentMethod');
            if ($paymentMethod == 'requsetRunner') {
                $form->bind($request->request->get('requestRunner'));
                if ($form->isValid()) {
                    //problem is here
                    $address = $form->getData();
                    $return = $orderService->createOrder($paymentMethod, $address['requestRunner']);
                }
            }
        }
    }

表单类代码为

   public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder
                ->add('id', 'hidden')
                ->add('buildingNo', 'text',array(
                    'mapped' => false
                ))
                ->add('floorNo', 'text',array(
                    'mapped' => false
                ))
                ->add('street', 'text',array(
                    'mapped' => false
                ))
                ->add('city', 'text')
                ->add('landmark', 'text',array(
                    'mapped' => false
                ))
                ->add('apartmentNo', 'text',array(
                    'mapped' => false
                ))
                ->add('name', 'text')
                ->add('phoneNo', 'text')
                ->add('notes', 'textarea')
                ->add('currency', 'choice', array(
                    'choices' => array(
                        'EGP' => 'EGP',
                        'USD' => 'USD'
                    ))
        );
    }

我的问题：** 当我将请求绑定到表单时，我得到的对象充满了 NULL 当我打印$request->request->all(); 我在发布请求中得到如下值

array (size=2)
  'paymentMethod' => string 'requsetRunner' (length=13)
  'requestRunner' => 
    array (size=12)
      'city' => string 'Cairo' (length=5)
      'buildingNo' => string '' (length=0)
      'street' => string '38 Hassnin Abdel Kader, Nasr City' (length=33)
      'apartmentNo' => string '' (length=0)
      'floorNo' => string '0' (length=1)
      'id' => string '' (length=0)
      'name' => string '' (length=0)
      'phoneNo' => string '' (length=0)
      '_token' => string '1a8d21d49a5eb612a8b863b792b89b0ed0bb8b67' (length=40)
      'currency' => string 'EGP' (length=3)
      'landmark' => string 'Next to supermarket' (length=19)
      'notes' => string '' (length=0)

我试过了

$form->bind($request->request->get('requestRunner'));

和

$form->bind($request));

因为 Symfony 2.2 应该获取数组并按照文档所述获取表单，但两者都不起作用

我想我知道问题出在哪里了。

没有任何东西可以绑定到请求。

我的意思是没有要映射到的 requestRunner 对象。您有两个选择，要么在表单创建中传递它，要么稍后使用$form->setData($requestRunner)。

我没有测试过，但这应该可以工作：

public function checkoutAction(Request $request) {
        $securityContext = $this->container->get('security.context');
        $obj  = new RequestRunner();
        $form = $this->createForm(new RequestRunnerType(), $obj );
        $data = array();

        if ($request->getMethod() == 'POST') {
            $orderService = $this->container->get('order_service');
            $paymentMethod = $request->get('paymentMethod');
            if ($paymentMethod == 'requsetRunner') {
                $form->bind($request->get('requestRunner'));
                if ($form->isValid()) {
                    //problem is here
                    //and here you can use the $obj variable what will be filled with the request data
                    $return = $orderService->createOrder($paymentMethod, $obj);
                }
            }
        }
    }

如果我正确获取了您的代码，您想将整个 requestRunner 传递给 createOrder 函数，对吗？

我也改变了一些位，你不需要getRequest() 因为你在函数的参数列表中，如果你从请求中提取数据，你可以在请求上使用get函数，或$this->getRequest()->get('input name')。

如果不能这样工作，则从 createForm 中删除 $obj 并在 bind 之前使用 $form->setData($obj) 功能。 （抱歉不记得哪个是2.2，哪个是2.3方式）
