Translate select options in Symfony2 class forms

Question

I'm using a class form in Symfony2 Beta3 as follows:

namespace Partners\FrontendBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;

class ConfigForm extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder->add('no_containers', 'choice', array('choices' => array(1 => 'yes', 0 => 'no')));
        ...

I want to translate the 'yes' and 'no' options, but I don't know how to use the translator here.

Answer 1

You can use the translation resources as usual. This worked for me:

    $builder->add('sex', 'choice', array( 
        'choices'   => array(
            1 => 'profile.show.sex.male', 
            2 => 'profile.show.sex.female',
        ),
        'required' => false,
        'label'     => 'profile.show.sex.label',
        'translation_domain' => 'AcmeUserBundle'
    ));

And then add your translations to the Resources->translations directory of your Bundle.

Update from @CptSadface:

In symfony 2.7, using the choice_label argument, you can specify the translation domain like this:

'choice_label' => 'typeName',
'choice_translation_domain' => 'messages',

Without specifying the domain, options are not translated.
