Question

我有一个简单的Symfony3表单，但正如预期的那样，当表单被GETed时，它会生成一个包含表单名称的丑陋url。像这样：

...php?party_form%5Bplace%5D=Milan&party_form%5Bdate%5D=01%2F01%2F2017&party_form%5Bsave%5D=&party_form%5B_token%5D=KMN745JpTUyZZQSRnP5kd6YHQnQhAlU9eHtMwZ-zi7g

我希望从网址中删除party_form。

在this次问题后，我做了以下更改：

class PartyForm extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->setMethod('GET')
            ->add( $builder
                ->create('place', TextType::class)
                ->addModelTransformer(new CallbackTransformer(
                    function ($placesAsArray) {
                        // transform the array to a string
                        if ($placesAsArray) {
                            return implode(', ', array_values($placesAsArray));
                        }
                    },
                    function ($placesAsString) {

                        // transform the string back to an array
                        $rawPlaceArray = explode(', ', $placesAsString);

                        // If the place doesn't have city, province and country don't search for it.
                        // validation constraints on place will throw an error.
                        if (count($rawPlaceArray) == 3) {
                            $keys = array('city', 'province', 'country');
                            return array_combine($keys, $rawPlaceArray);
                        }
                    }
                ))

            )
            ->add('date', DateType::class,
                  array(
                      'widget' => 'single_text',
                      'format' => 'dd/MM/yyyy',
                  )
            )
            ->add('save', SubmitType::class,
                  array(
                      'label' => 'Find List',
                  )
            );

    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'AppBundle\Entity\Frontend\Event',
            'required' => false
        ));
    }

   // This function was to be ovveridden
    public function getBlockPrefix()
    {
        return null;
    }

但是现在表单提交的字段为null！我在这里缺少什么？

尝试：

// This function was to be ovveridden
public function getBlockPrefix()
{
    return '';
}

提交表单时如何从URL中删除表单名称？
