I can´t concatenate a label with string in symfony3

Question

I can´t concatenate a label with string.

->add('originador', EntityType::class, array(
    'label' =>   "app.label.x_originador".'*',
    'class' => 'AppBundle:Usuario',
    'em' => $options['entityManager'],
    'query_builder' => function (EntityRepository $er) {
        return $er->createQueryBuilder('u');    
    },
    'placeholder' => '',
    'required' => false,
))

In the part of 'label' => "app.label.x_originador".'*', I need that the result be Originador*,because the label is for required value.

The result that I recieve is app.label.x_originador*

Please, help me to get Originador* as result.

You can pass the translator service to your form type and translate then concatenate like this:

class MyFormType extends AbstractType
{
    private $translator;

    public function __construct(TranslatorInterface $translator)
    {
        $this->translator = $translator;
    }

    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('originador', EntityType::class, array(
                'label' =>   $this->translator->trans('app.label.x_originador',[], 'domain').'*',
                'class' => 'AppBundle:Usuario',
                'em' => $options['entityManager'],
                'query_builder' => function (EntityRepository $er) {
                    return $er->createQueryBuilder('u');
                },
                'placeholder' => '',
                'required' => false,
            ));
        }
    }

juste replace "domain" with your translation domain.

EDIT: but yeah, the best solution is probably @ccKep's one
