php - @Assert\NotBlank 验证在 symfony 4 中不能以嵌入式形式工作

问题描述

我有一个名为BlockType的表单，它有一个名为BlockHeroStaticImageType的嵌入式表单。嵌入表单BlockHeroStaticImageType的名为“ title ”的字段包含验证注释，如下所示（请参阅下面的BlockHeroStaticImage 实体）。当我在表单中将标题留空并尝试保存表单时，不会触发表单验证。验证应该失败，但事实并非如此。我签入了控制器，尽管标题为空，但它仍返回 true。我在这里想念什么？请帮忙。@Assert\NotBlank()$form->isValid()

块类型表格

class BlockType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('content', TextareaType::class, [
                'required' => false,
                'attr' => [
                    'class' => 'ckeditor',
                    'data-field' => 'content'
                ]
            ])
            ->add('blockHeroStaticImages', CollectionType::class, [
                'entry_type' => BlockHeroStaticImageType::class,
                'entry_options' => ['label' => false],
                'label' => 'Hero Static Image',
                'allow_add' => true,
                'allow_delete' => true,
                'by_reference' => false,
                'help' => '<a data-collection="add" class="btn btn-info btn-sm" href="#">Add Hero Static Image</a>',
                'help_html' => true,
                'attr' => [
                    'data-field' => 'blockHeroStaticImages'
                ]
            ]);

    }

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