Question

我正在开发一个基于Symfony的项目，我正在使用FosUserBundle。

我遇到问题，在尝试渲染CollectionType:Class时，我想让我的用户在我的数据库中填充我尚未拥有的内容。

从我在Symfony文档中读到的内容来看，为了使该类型工作，有必要将一组数据Pre Set作为条目。

所以我的问题是，“无论如何，我是否有创建数据数组并将其传递到我的字段以使其显示？”

我的工作室类型：

class WorkshopType extends AbstractType implements ContainerAwareInterface
{
    use ContainerAwareTrait;
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add( 'title', TextType::class, array('label'=>"Titre"))
            ->add( 'goal', TextareaType::class, array('label'=>"But"))
            ->add( 'theme', TextType::class, array('label'=>"Theme"))
            ->add( 'target', TextType::class, array('label'=>"Cible"))
            ->add( 'summary', TextareaType::class, array('label'=>"Résumé"))
            ->add('maxParticipants', NumberType::class, array('label'=>"Nombre de Participants Maximum", 'data' => 0))
            ->add('moderatorsNumber', NumberType::class, array('label'=>"Nombre de Modérateurs",'data' => 0))
            ->add('materials', CollectionType::class, [
                 //'label' => 'Matériaux',

您可以将数组作为默认值传递：

'choices' => $yourArray,

为Collection Type创建数据数组
