问题描述
你好， 我无法使表单数据持久化。它只在一侧起作用。
“目标”表单可让您创建目标并将其链接到活动：可以。
在“活动”表格中，我还有一个“目标”字段，该字段显示相关目标，但似乎无法对其进行修改。我的选择只保留在“目标”表单一侧。
我只希望能够在活动页面上选择一些内容，
TargetType.php：
<?php
namespace App\Form;
use App\Entity\Target;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class TargetType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder,array $options)
{
$builder
->add('name')
->add('activity')
;

public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Target::class,]);
