Question

我正在努力学习symfony表格。我想为用户构建一个表单。此用户作为收集产品（nom，description）的arraycollection字段。

我想创建一个表单，为每个传递给表单构建器的产品创建一个复选框。实际上它只创建了没有标签的输入字段......这是我的UserType类的代码：

public function buildForm(FormBuilderInterface $builder, array $options)
{

    $builder->add('nom')->add('prenom')->add('mail')->add('tel1')->add('tel2', TextType::class, array('required' => false))
        ->add('username')->add('password', PasswordType::class)
        ->add('groupe', ChoiceType::class, array(
            'choices' => array('Administrateur' => 'ROLE_SUPER_ADMIN', 'Gérant' => 'ROLE_ADMIN', 'Opérateur' => 'ROLE_USER'),
            'expanded' => true,
        ))
        ->add('produits', CollectionType::class, array(
            'entry_type' => ProduitType::class
        ))
    ;
}

/**
 * {@inheritdoc}
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => User::class
    ));
}

/**
 * {@inheritdoc}
 */
public function getBlockPrefix()
{
    return 'gestcoupons_userbundle_user';
}

这是我的ProduuctType代码：

public function buildForm(FormBuilderInterface $builder, array $options)
{

    $builder->add('nom')->add('prenom')->add('mail')->add('tel1')->add('tel2', TextType::class, array('required' => false))
        ->add('username')->add('password', PasswordType::class)
        ->add('groupe', ChoiceType::class, array(
            'choices' => array('Administrateur' => 'ROLE_SUPER_ADMIN', 'Gérant' => 'ROLE_ADMIN', 'Opérateur' => 'ROLE_USER'),
            'expanded' => true,
        ))
        ->add('produits', CollectionType::class, array(
            'entry_type' => ProduitType::class
        ))
    ;
}

/**
 * {@inheritdoc}
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => User::class
    ));
}

/**
 * {@inheritdoc}
 */
public function getBlockPrefix()
{
    return 'gestcoupons_userbundle_user';
}

这是我的UserController代码：

public function ajouterAction(Request $request){

    $this->denyAccessUnlessGranted('ROLE_ADMIN', null, 'Unable to access this page!');
    $em = $this->getDoctrine()->getManager();
    $produits = $em->getRepository('ProduitBundle:Produit')->findAll();
    $societes = $em->getRepository('SocieteBundle:Societe')->findAll();
    $user = new User();
    foreach ($produits as $produit) {
        $user->getProduits()->add($produit);
    }
    $form = $this->createForm('GestCoupons\UserBundle\Form\UserType', $user);
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $em->persist($user);
        $em->flush($user);

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

    return $this->render('user/new.html.twig', array(
        'user' => $user,
        'form' => $form->createView(),
    ));
}

先谢谢你的帮助。

您应该使用 Symfony \ Bridge \ Doctrine \ Form \ Type \ EntityType 而不是CollectionType。

在您的UserType

中

use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use AppBundle\Entity\Produit;

public function buildForm(FormBuilderInterface $builder, array $options)
{

    $builder
        ->add('nom')
        ->add('prenom')
        ->add('mail')
        ->add('tel1')
        ->add('tel2', TextType::class, array(
            'required' => false
        ))
        ->add('username')
        ->add('password', PasswordType::class)
        ->add('groupe', ChoiceType::class, array(
            'choices' => array(
                'Administrateur' => 'ROLE_SUPER_ADMIN',
                'Gérant' => 'ROLE_ADMIN',
                'Opérateur' => 'ROLE_USER'
            ),
            'expanded' => true,
        ))
        ->add('produits', EntityType::class, array(
            'class' => Produit::class,
            'multiple' => true,
            'expanded' => true,
            'label' => 'nom' //If you don't have a __toString method in your Produit Entity
        ))
    ;
}

/**
 * {@inheritdoc}
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => User::class
    ));
}

/**
 * {@inheritdoc}
 */
public function getBlockPrefix()
{
    return 'gestcoupons_userbundle_user';
}

通过这种方式，您的数据库中的每个产品实体都会有一个复选框，只有您检查的实体才会与您的用户相关联
