            ->add('username')
            ->add('password', PasswordType::class)
            ->add('repassword', PasswordType::class, [

            ->getForm();
   

query builder

	$builder
        ->add('parent', EntityType::class, [
            'class' => 'KitNewsBundle:Category',
            'query_builder' => function(CategoryRepository $repo){
                return $repo->getParentCategory();
            },
            'choice_label' => 'name',
            'label' => '父级分类'
        ]);
	// query
	class CategoryRepository extends \Doctrine\ORM\EntityRepository
	{
	
	    public function getParentCategory()
	    {
	        return $this->createQueryBuilder('c')
	            ->select('c')
	            ->where('c.parentId = 1')
	            ->andWhere('c.status = 1')
	            ->orderBy('c.id', 'ASC');
	    }

2. ChoiceType

    $builder->add('rolename', null, [
            'label' => '角色名称'
        ])
            ->add('note', null, [
            'label' => '备注'
        ])
            ->add('status', ChoiceType::class, [
            'choices' => [
                '启用' => 1,
                '禁用' => 0
            ],
            'expanded' => true,
            'label' => '状态',
             'data' => 1,
            'label_attr' => [
                'class' => 'radio-inline'
            ]
        ])
            ->add('submit', SubmitType::class, [
            'label' => '提交'
        ]);
    // 为radio设置属性
    ->add('status', ChoiceType::class, [
        'choices' => [
            '启用' => 1,
            '禁用' => 0
        ],
        'expanded' => true,
        'label' => '状态',
        'data' => $options['data_status'],
        'label_attr' => [
            'class' => 'radio-inline'
        ],
        'choice_attr' => function ($val, $key, $index) {
            // adds a class like attending_yes, attending_no, etc
            return [
                'lay-filter' => 'status-radio'
            ];
        }
    ])

            ->add('plainPassword', RepeatedType::class, [
            'type' => PasswordType::class,
            'first_options' => ['label' => '密码'],
            'second_options' => ['label' => '确认密码'],
        ]);
   

4. options

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name', null, [
            'label' => '类别名称',
            'attr' => [
                'lay-verify' => "required",

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(

• ChoiceType详解

  • 两个关键参数

  目的类型	expanded	multiple
  单选下拉框(select)	false	false
  复选下拉框(multi-select)	false	true
  单选框（radio）	true	false
  复选框（checkboxes）	true	true

  • 示例

      // 单选框
      ->add('status', ChoiceType::class, [
          'choices' => [
              '启用' => 1,
              '禁用' => 0
          ],
          'expanded' => true, //单选，multiple默认false
          'label' => '状态',
          'data' => 1,
      ])
      //expanded，multiple默认值均为false，所以如下代码为单选下拉框
      ->add('dropdown', ChoiceType::class, [
          'choices' => [
              '下拉菜单1' => 1,
              '下拉菜单2' => 0
          ],
          'label' => '下拉名称',
          'data' => 1,
      ])
      //复选框
      ->add('hobbit', ChoiceType::class, [
          'choices' => [
              '篮球' => 1,
              '足球' => 2,
              '排球' => 3,
          ],
          'expanded' => true,
          'multiple' => true,
          'label' => '爱好',
          'data' => [1], //此处需要注意，由于值为多个，所以默认选中需要传数组
      ])
