我想在 FormType 事件侦听器中设置按钮，但是当我这样做时，我得到了那个错误：

该选项auto_initialize不存在。已知选项有：attr, block_name, disabled, label,translation_domain

如果我设置了事件侦听器，它就可以工作。有人能帮我吗？

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

        $builder
            ->add('enquirer', new ContactType(), array(
                "by_reference" => true,
                "required" => true,
                'validation_groups' => array('required'),
                'details_field' => true,
            ))
            [...]

        ;
        $builder->addEventListener(FormEvents::POST_SET_DATA, function (FormEvent $event) {
            $client=$event->getData();
            $form=$event->getForm();
            if($client && !$client->getId()){
                $form->add("createBtn", "submit", array("label"=>"Create", "attr"=>array("class"=> "btn btn-primary")));
            } else {
                $form->add("saveBtn", "submit", array("label"=>"Save", "attr"=>array("class"=> "btn btn-primary")));
            }
        });
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Sme\ClientBundle\Entity\Client',
        ));
    }

    public function getName()
    {
        return 'client_form';
    }
}

堆栈跟踪：我没有设置“auto_initialize”，但在 FormFactory 中设置了。有任何想法吗？

查看 \vendor\symfony\symfony\src\Symfony\Component\Form\Form.php 我发现该代码：

public function add($child, $type = null, array $options = array())
{
[...]
if (!$child instanceof FormInterface) {
            if (!is_string($child) && !is_int($child)) {
                throw new UnexpectedTypeException($child, 'string, integer or Symfony\Component\Form\FormInterface');
            }

            if (null !== $type && !is_string($type) && !$type instanceof FormTypeInterface) {
                throw new UnexpectedTypeException($type, 'string or Symfony\Component\Form\FormTypeInterface');
            }

            // Never initialize child forms automatically
            $options['auto_initialize'] = false;

            if (null === $type) {
                $child = $this->config->getFormFactory()->createForProperty($this->config->getDataClass(), $child, null, $options);
            } else {
                $child = $this->config->getFormFactory()->createNamed($child, $type, null, $options);
            }
        } elseif ($child->getConfig()->getAutoInitialize()) {
            throw new RuntimeException(sprintf(
                'Automatic initialization is only supported on root forms. You '.
                'should set the "auto_initialize" option to false on the field "%s".',
                $child->getName()
            ));
        }
[...]
}

现在我更困惑了。

谢谢

尝试升级到最新版本（当前为 2.3.6）。似乎此错误已在2.3.4中修复。
