我的构建表单

public function buildForm(FormBuilderInterface $builder, array $options) {
    $builder->add('uid', ChoiceType::class, array(
                    'choices'   => array('Dla dzwoniących' => 1, 'Oddzwaniająca' => 2),
                    'required'  => false,
                    'label' => 'Wybierz maszynę',
            ))
            ->add('buttonNumber', ChoiceType::class, array(
                    'choices'   => array('1' => 1, '2' => 2, '3' => 3, '4' => 4, '5' => 5, '6' => 6, '7' => 7, '8' => 8, '9' => 9),
                    'required'  => false,
                    'label' => 'Numer przycisku'
            ))
            ->add('linkToMusic', TextType::class, [
                'label' => 'Adres URL do muzyki',
                'required' => true
            ])
            ->add('telephoneNumber', PhoneNumberType::class, [
                'label' => 'Numer Telefonu',
                'required'  => false,
                'widget' => PhoneNumberType::WIDGET_COUNTRY_CHOICE,
                'preferred_country_choices' => ['PL']
            ])
            ->add('acceptRegulations', ChoiceType::class, array(
                    'choices'   => array('1' => 1, '2' => 2, '3' => 3, '4' => 4, '5' => 5, '6' => 6, '7' => 7, '8' => 8, '9' => 9),
                    'required'  => false,
                    'label' => 'Numer przycisku do akceptacji regulaminu'
            ))
            ->add('submit', \Symfony\Component\Form\Extension\Core\Type\SubmitType::class, array(
                'label' => 'Zapisz'
            ));
}

我添加了$buttoNumber、$linkToMusic 等，但我没有添加$uid 我尝试清除我的缓存，但我不知道我有问题。帮帮我:)

Answer 1

'choices'   => array('Dla dzwoniących' => 1, 'Oddzwaniająca' => 2),

你传递一个整数，但你需要传递一个 VoiceAnswerMachine 类型的实体

Answer 2

为了补充之前糟糕的答案...

你可以改变

->add('buttonNumber', ChoiceType::class, array(
                    'choices'   => array('1' => 1, '2' => 2, '3' => 3, '4' => 4, '5' => 5, '6' => 6, '7' => 7, '8' => 8, '9' => 9),
                    'required'  => false,
                    'label' => 'Numer przycisku'
            ))

通过

->add('buttonNumber', EntityType::class, array(
        'class' => 'AppBundle:ButtonNumber',
        'label' => 'Button number',
    ))

并在您的实体中设置 __toString() 方法

public function __toString() {
    return $this->name;
}

记得实现：

use Symfony\Bridge\Doctrine\Form\Type\EntityType;

在你的表单类中。
