Question

我使用formType（TagsType）在一个包中创建了一个标签系统，我将其包含在我的主formType中（见下文）。我想知道如何将$ options参数值从MyFormType发送到TagsType。

//...

use EC\TagBundle\Form\Type\TagsType;

class MyFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {


    $builder        

    //...
        ->add('tags', TagsType::class)
    //...
    ;
    }
}

我的TagsType

//...

use Symfony\Component\Form\Extension\Core\Type\TextType;

class TagsType extends AbstractType
{
    /**
     * @var ObjectManager
     */
    private $manager;

    public function __construct(ObjectManager $manager)
    {
        $this->manager = $manager;
    }

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

        $builder
            ->addModelTransformer( new CollectionToArrayTransformer(), true )
            ->addModelTransformer( new TagsTransformer($this->manager), true )
        ;
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefault('attr', [
            'class' => 'tag-input',

        ]);
        $resolver->setDefault('required', false);
    }

    public function getParent()
    {
        // Il retourne un TextType par défaut.
        return TextType::class;
    }
}

我找到了。就这样做：

->add('tags', TagsType::class, ['empty_data' => $options])

TagsType.php

$options = $options['empty_data'];

Symfony 3：将$ options参数值从formType发送到underFormType
