Question

这是我在SF2上的第一步。我想在包含其他实体的实体上设置多步表单。

我有一个表单类型（缩写）

class ApplicationFormType extends AbstractType
{
    protected $_step = 1;

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        if ($this->_step == 1) {
            $builder
                ->add('patient', new Type\PersonType())
                ->add('insurance', 'entity', array(
                    'class' => 'Acme\MainBundle\Entity\Insurance',
                ));
        } elseif ($this->_step == 2) {
            $nurse = new Type\PersonType();
            $nurse->requireBareData();
            $builder
                ->add('nurse', $nurse)
                ->add('nurse_type', 'entity', array(
                    'class' => 'Acme\MainBundle\Entity\NurseType',
                    'expanded' => true,
                    'multiple' => false,
                ))
                ->add('nursing_support', 'checkbox', array(
                    'required' => false,
                ));
        }
    }

    public function setStep($step)
    {
        $this->_step = $step;
    }

我的控制器看起来像

public function assistAction() {
    $request = $this->getRequest();

    $step = $this->getSession()->get('assist_step', 1);
    if ($request->getMethod() != 'POST') {
        $step = 1;
        $this->getSession()->set('assist_data', NULL);
    }
    $this->getSession()->set('assist_step', $step);
    $application = new Application();
    $type = new ApplicationFormType();
    $type->setStep($step);

    $form = $this->createForm($type, $application, array(
        'validation_groups' => array($step == 1 ? 'FormStepOne' : 'FormStepTwo'),
    ));
    if ($request->getMethod() == 'POST') {
        $form->bindRequest($request);
        if ($form->isValid()) {
            if ($step == 1) {

                $data = $form->getData();
                $this->getSession()->set('assist_data', serialize($data));
                $this->getSession()->set('assist_step', ++$step);
                $type = new ApplicationFormType();
                $type->setStep($step);
                $form = $this->createForm($type, $application, array(
                    'validation_groups' => array('FormStepTwo'),
                ));

            } else {

                $step_1 = unserialize($this->getSession()->get('assist_data', ''));
                $data = $form->getData();
=>                $data->setPatient($step_1->getPatient());
=>                $data->setInsurance($step_1->getInsurance());
                $this->getSession()->set('assist_data', NULL);
                $this->getSession()->set('assist_step', 1);

            }
        }
    }

    return $this->render('Acme:Default:onlineassist.html.twig', array(
        'form' => $form->createView(),
        'step' => $step,
    ));
}

我的问题是，如果我必须单独“复制”第一个表单步骤的属性，例如：

$data->setPatient($step_1->getPatient());
$data->setInsurance($step_1->getInsurance());

或者我可以将会话中的反序列化数据与第二个表单步骤中的数据合并吗？或者有一种完全不同的方法吗？

可以根据stackoverflow上的响应将实体序列化并放入会话中。

如果每个表单都是不同的类型，我建议你拆分多种类型的表单。

以下是我设想的方式：

public function submitAction($step = 1)
{
    switch ($step) {
        case 1:
            $entity = new EntityOne();
            $form = $this->createForm(new EntityOneType(), $entity);
            $template = "template_one.html.twig";
            $redirect = $urlToStepTwo; // which redirects to this controller action with $step = 2
            break;
        case 2:
            $entity = new EntityTwo();
            $form = $this->createForm(new EntityTwoType(), $entity);
            $template = "template_two.html.twig";
            $redirect = $urlToStepThree; // which redirects to this controller action with $step = 3
            break;
        case 3:
            $entity = new EntityThird();
            $form = $this->createForm(new EntityThreeType(), $entity);
            $template = "template_three.html.twig";
            $redirect = $urlToConfirmPage; // which redirects to another controller action that unserialize all entities and save them in the DB
            break;
        default:
            throw $this->createNotFoundException();
            break;
    }

    $request = $this->get('request');
    $session = $this->get('session');

    if ($request->isMethod('post') === true) {

        $form->bind($request);

        if ($form->isValid() === true) {
            $session->set('entity_'. $step, serialize($entity));

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

    $params = array(
        'form'    => $form->createView(),
        'entity'  => $entity
    );

    return $this->render($template, $params);
}

Answer 2

好的，除了单独设置pre-step字段之外没别办法，比如

$pre_step = unserialize($this->getSession()->get('assist_data', ''));
$data->setPatient($pre_step->getPatient());
$data->setInsurance($pre_step->getInsurance());
$data->setInsuranceNumber($pre_step->getInsuranceNumber());
$data->setInsuranceLevel($pre_step->getInsuranceLevel());

这就是我到目前为止所做的事情。
