【问题描述】：
我来找你解决脑残问题。
所以我有一个生成子表单的基本表单。我想将数组数据传递给子表单，但数组传递是数据失真的。
我也有一个关于我认为是链接的 CSRF 令牌的错误。 CSFR Error
控制器：
public function evaluatemocep($id,Request $request): Response
{
if ($this->getUser()) {
$em = $this->getDoctrine()->getManager();
$efficiency = new Efficiency();
$problem = $em->getRepository('App:Problem')->find($id);
$efficiency->setLinkProblem($problem);
$form = $this->createForm(EfficiencyForm::class,$problem,['data'=>['id' => $id]]);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em->persist($efficiency);
$em->flush();
}
return $this->render('efficiency/efficiencyform.html.twig', [
'problem' => $problem,
'form' => $form->createView()]);
}
return new Response("You must be login");
}
效率形式：
class EfficiencyForm extends AbstractType {
/**
* {@inheritDoc}
*/
private $em;
public function __construct(EntityManagerInterface $em)
{
$this->em = $em;
}
public function buildForm(FormBuilderInterface $builder, array $options) {
$problem = $this->em->getRepository(Problem::class)->find($options['data']['id']);
$MOCrepo = $problem->getMOC();
$EOrepo = $problem->getEO();
$MOCA = array();
$EOA = array();
foreach ($EOrepo as $eo){
array_push($EOA, $eo);
}
foreach ($MOCrepo as $moc){
array_push($MOCA, $moc);
}
$builder->add('EffCollection', CollectionType::class, [
'entry_type' => EfficiencyMOCEOType::class,
'entry_options' => array('label' => false, 'EOA' => $EOA, 'MOCA' => $MOCA),
'allow_add' => true,
'prototype' => true,
'by_reference' => false,
'allow_delete' => true,
'mapped' => false,
'label' => 'Thinking about health'
]);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'allow_extra_fields' => true
]);
}
public function getBlockPrefix() {
return 'RateCouple';
}
}
效率MOCEO类型：
<?php
namespace App\Form;
use App\Entity\Efficiency;
use App\Entity\EO;
use App\Entity\MOC;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class EfficiencyMOCEOType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$EOA = $options['EOA'];
$MOCA = $options['MOCA'];
$builder
->add('EO', EntityType::class, [
'class' => EO::class,
'label' => 'Ethical objective',
'choices' => $EOA,
'choice_attr' => function ($choice){return ['title' => $choice->getDescription()];},
'required' => true])
->add('MOC', EntityType::class,[
'class' => MOC::class,
'label' => 'Model Of Care',
'choices' => $MOCA,
'choice_attr' => function ($choice){return ['title' => $choice->getDescription()];},
'required' => true])
->add('rateRiskCurrent', ChoiceType::class,[
'label' => 'Evaluate the risks of the selected couple : ',
'choices' => [
'High Risk' => 3,
'Medium Risk' => 2,
'Low Risk' => 1
],
'required' => true
])
->add('rateBenefitCurrent', ChoiceType::class,[
'label' => 'Evaluate the benefits of the selected couple : ',
'choices' => [
'High Benefit' => 3,
'Medium Benefit' => 2,
'Low Benefit' => 1
],
'required' => true
]);
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Efficiency::class,
'MOCA' =>[],
'EOA' => [],
'allow_extra_fields' => true
]);
}
}

任何帮助将不胜感激！
【问题讨论】：
-
您好，如果您能更详细地描述实际问题是什么，这将很有帮助，因为“我想将数组数据传递给子表单，但数组传递是数据失真。”不是特别清楚。由于您的表单已经将问题实体传递给它，因此您不应将其 id 作为选项传递，而应使用表单事件，特别是 PRE_SET_DATA 表单事件。一般来说，数据访问应该是自动的，而不是通过选项来完成，如果可以的话。表单组件实际上非常聪明，您应该发挥它的优势。
-
问题是我将数据（$EOA 和 $MOCA）传递给第二种形式，但我在第二种形式中的数据不是我在第一种形式中获得的数据。我会尝试克服 id argu 看看是否有区别！
-
解决了 CSRF 问题，但我的子表单上仍然没有得到正确的数据
-
好吧，我可以告诉你，就可见范围而言，eoa/moca 数组应该是正确的。您如何验证/检查它们不是？
-
我直接从数据库中检查 $EOA 和 $MOCA 是基于与问题实体多对多相关的实体的数组，例如问题 id 4 得到 2 EO 和 2 MOC，但形式为 i只得到一个带有错误标签的标签（我实际上得到了问题 1 的 EO 和 MOC ..）
