我正在使用 JMS Translation Bundle 来提取我的翻译。一切正常,但是当我尝试从表单构建器中提取翻译消息时,我收到以下消息:

[JMS\TranslationBundle\Exception\RuntimeException]
  Unable to extract translation id for form label from non-string values, but got "PHPParser_Node_Expr_MethodCall" in /srv/local.project.com/app/../src/Project/MyBundleBundle/Form/Type/EmailType
  .php on line 30. Please refactor your code to pass a string, or add "/** @Ignore */".

我使用的代码如下:

public function __construct($translator)
    {
        //translation service passed from controller
        $this->trans = $translator;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('email', 'repeated', array(
                'type' => 'email',
                'first_name' => 'email',
                'second_name' => 'email-repeat',
                 //TRANSLATION GIVES ERROR ON NEXT LINE          
                'invalid_message' => $this->trans->trans('online.form.email.errors.equal', array(), 'messages_roadrunner'), 
                'error_bubbling' => true,
                'first_options'  => array('label' => $this->trans->trans("online.form.email.fields.one", array(), 'messages_roadrunner')),
                'second_options' => array('label' => $this->trans->trans("online.form.email.fields.second", array(), 'messages_roadrunner')),
            )
        );

        $builder->add('optin', 'checkbox', array(
            'required'  => false,
            'label' => $this->trans->trans('online.form.email.fields.optin', array(), 'messages_roadrunner')
        ));

    }

奇怪的是,在我的控制器中我使用相同的东西,但一切正常:

$content['text'] = $this->get('translator')->trans('online.tariff.text.no_advice', array(), 'messages_roadrunner');

有没有人有这个问题的经验?

提前致谢!

不要忘记,默认情况下,提取器配置为自动从FormBuilder::add()调用参数中提取值(请参阅文档)。在您的情况下,它期望'label'是一个字符串,但它包含一个方法调用,并且您的错误出现了。

这实际上意味着您不必将翻译器也传递给FormType
