我正在使用 Symfony 3.1.9 (localhost)，并且我已经为多步骤表单安装了 CraueFormBundle。当我访问表单时，我500 internal server error在 longs 中没有任何内容（Symfony 不处理发生的问题）。
我在 apache 错误日志中有这个：

那64个工作线程是什么？！为什么我的表格不起作用？

表单流类：
<?php
namespace VS\CrmBundle\Form\Wizard\AddChild;
use Craue\FormFlowBundle\Form\FormFlow;
use Craue\FormFlowBundle\Form\FormFlowInterface;
class AddChildFlow extends FormFlow {
protected function loadStepsConfig()
{
return array(
array(
'label' => 'ChildData',
'form_type' => 'VS\CrmBundle\Form\Wizard\AddChild\AddChildStep1'
),
array(

'label' => 'ChildFamily',
'form_type' => 'VS\CrmBundle\Form\Wizard\AddChild\AddChildStep3'
),
array(
'label' => 'confirmation',
),
);
}
}
步骤1 ：
<?php
namespace VS\CrmBundle\Form\Wizard\AddChild;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use VS\CrmBundle\Entity\Person;
use VS\CrmBundle\Entity\Relationship;
use VS\CrmBundle\Form\PersonChildType;
use VS\CrmBundle\Form\RelationshipFromCurrentUserType;
class AddChildStep1 extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('currenUserChildRelationship', RelationshipFromCurrentUserType::class, array(
'data_class' => Relationship::class
))
->add('child', PersonChildType::class, array(
'data_class' => Person::class
));
}
public function getBlockPrefix()
{
return 'AddChildStep1';
}
}
第2步 ：
<?php
namespace VS\CrmBundle\Form\Wizard\AddChild;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use VS\CrmBundle\Entity\MedicalRecord;
use VS\CrmBundle\Form\MedicalRecordType;
class AddChildStep2 extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('childsMedicalRecord', MedicalRecordType::class, array(
'data_class' => MedicalRecord::class
));
}
public function getBlockPrefix()
{
return 'AddChildStep2';
}
}
第 3 步：
<?php
namespace VS\CrmBundle\Form\Wizard\AddChild;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\FormBuilderInterface;
use VS\CrmBundle\Form\RelationshipType;
class AddChildStep3 extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('childsFamily', CollectionType::class, array(
'entry_type' => RelationshipType::class,
'allow_add' => true
));
}
public function getBlockPrefix()
{
return 'AddChildStep3';
}
}
服务 ：
vs_crm.form.flow.add_child:
class: VS\CrmBundle\Form\Wizard\AddChild\AddChildFlow
parent: craue.form.flow
和控制器动作：
public function addChildAction()
{
// Our form data class
$formData = new AddChildWizard();
// We call service (craue form flow)
$flow = $this->get('vs_crm.form.flow.add_child');
$flow->bind($formData);
$form = $flow->createForm();
if($flow->isValid($form))
{
$flow->saveCurrentStepData($form);
if($flow->nextStep())
{
$form = $flow->createForm();
}
else
{
// flow finished
//$em = $this->getDoctrine()->getManager();
//$em->persist($formData);
//$em->flush();
//$flow->reset();
//return $this->redirect();
//return new JsonResponse(array('PERSIST AND FLUSH BRO'));
}
}
return $this->render('VSCrmBundle:Parent:add-child.html.twig', array(
'form' => $form->createView(),
'flow' => $flow
));
}
