因此，我在两个实体之间建立了

        ));
    }
}

子表单类型：

class Parent{
   /**

    /**

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name')
            ->add('children', CollectionType::class, array(
            'entry_type' => ChildType::class,
            'allow_add' => true

        ));
    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Bundle\Entity\Parent'
        ));
    }

}

class ChildType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name');
    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Bundle\Entity\Child'
        ));
    }
}

之后，我在控制器内创建了如下表单：

function saveAction(Request $request){
    $parent = new Parent();
    $form = $this->createForm('Bundle\Form\ParentType', $parent);
    $form->handleRequest($request);
    if ($form->isSubmitted()) {
            //--after submitted the form I just want to display the children
            die(var_dump($parent->getChildren()));


        }
}

class ParentType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name')
            ->add('children', CollectionType::class, array(
            'entry_type' => ChildType::class,
            'allow_add' => true,
            'by_reference' => false

        ));
    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Bundle\Entity\Parent'
        ));
    }

}

class ChildType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name')      ;

    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Bundle\Entity\Child'
        ));
    }
}

当然，我正在使用jquery从symfony的

FormBuilder

提供的数据原型创建子对象，但是表单没有看到它们

我在这里遗漏了什么？

可能是因为你的“设定者”没有被调用

尝试通过引用添加

，并将其设置为false
，如下所示：
function saveAction(Request $request){
    $parent = new Parent();
    $form = $this->createForm('Bundle\Form\ParentType', $parent);
    $form->handleRequest($request);
    if ($form->isSubmitted()) {
            //--after submitted the form I just want to display the children
            die(var_dump($parent->getChildren()));


        }
}

{
    /**

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

            ->add('children', CollectionType::class, array(
            'entry_type' => ChildType::class,
            'allow_add' => true,
            'by_reference' => false

        ));
    }

    /**

    public function configureOptions(OptionsResolver $resolver)

    }

    /**

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

        ));
    }
}

我没有时间真正测试你的代码。但是，您不必将父项
放在子项
表单中。因此，您的子表单类型应如下所示：
function saveAction(Request $request){
    $parent = new Parent();
    $form = $this->createForm('Bundle\Form\ParentType', $parent);
    $form->handleRequest($request);
    if ($form->isSubmitted()) {
            //--after submitted the form I just want to display the children
            die(var_dump($parent->getChildren()));


        }
}

class ParentType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name')
            ->add('children', CollectionType::class, array(
            'entry_type' => ChildType::class,
            'allow_add' => true,
            'by_reference' => false

        ));
    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Bundle\Entity\Parent'
        ));
    }

}

class ChildType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name')      ;

    }

    /**
     * {@inheritdoc}

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Bundle\Entity\Child'
        ));
    }
}

希望有帮助。

是的，将父项放入子表单类型是正确的，但将“by\u reference”设置为false仍不起作用。是的，将父项放入子表单类型是正确的，但将“by\u reference”设置为“by\u reference”设置为false仍然不起作用。您可以使用如下所示的query\u builder
