Question

假设我有此表单：

//...
class BananaType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('flavor');
        $builder->addEventListener(FormEvents::SUBMIT, function (FormEvent $event) {
            $form = $event->getForm();
            if ($form->get('flavor')->getData() === null) {
                $form->addError(new FormError('form.error.flavor_missing'));
            }
        }
    }
}

即使在messages.yml和validators.yml中都定义了消息 form.error.flavor_missing ，它也不会显示。

任何想法如何翻译？我希望我不必为了解决这个问题而以每种形式注入translator服务。

为什么不使用Validation Constraints

use Symfony\Component\Validator\Constraints as Assert;

// ...

class BananaType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('flavor', YourType::class, array(
            'constraints' => array(
                new Assert\NotNull(), // or any other
            ),
        ));
    }
}

您可以使用自定义消息

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('flavor', YourType::class, array(
            'constraints' => array(
                new Assert\NotNull(array(
                    'message' => 'form.error.flavor_missing'
                )),
            ),
        ));
    }

如果打开开发环境，则应该看到缺少的字符串。看看它们，您应该会看到域和预期的消息文件。
