The forms created with the Symfony Form component translate their labels and help messages automatically. However, the translations cannot contain any custom parameters because in the templates, the trans() Twig filter is called without passing any parameters.
In Symfony 4.3 we improved the translation of Symfony Forms allowing to define
custom translation parameters using three new config options:
label_translation_parameters, help_translation_parameters, and
attr_translation_parameters (this one is useful to translate placeholder
and title):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
class OrderType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('comment', TextType::class, [
'label' => 'Comment for the order of %company%',
'label_translation_parameters' => [
'%company%' => 'Acme Ltd.',
],
'help' => 'The address of %company% is %address%',
'help_translation_parameters' => [
'%company%' => 'Acme Ltd.',
'%address%' => '4 Form street, Symfonyville',
],
])
}
}Help the Symfony project!

Just miss a config-based option to add the "raw" filter after "trans" and it'll be perfect 👍
@Alex there's a new option in Symfony 4.3 called "help_html". Set it to "true" to output HTML contents as "raw". But I think there's no such option for "label".
