问题


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.

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.

I searched a while to find an answer, but finally I found out how Symfony translates form content. The easiest way in your case seems to be to just add a translation for "yes" and "no" by adding a YAML or XLIFF translation file to your application (e.g. app/Resources/translations/messages.de.yml) or your bundle. This is described here: http://symfony.com/doc/current/book/translation.html

The problem - in my opinion - is that you don't seem to be able to use custom translation keys. The guys from FOSUserBundle solve this (or a similar) problem with "Form Themes" (http://symfony.com/doc/2.0/cookbook/form/form_customization.html). Here are two significant lines of code to achieve the usage of the form element id as translation key:

https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/views/Registration/register_content.html.twig#L1 / https://github.com/FriendsOfSymfony/FOSUserBundle/blob/50ab4d8fdfd324c1e722cb982e685abdc111be0b/Resources/views/form.html.twig#L4

By adding a Form Theme you're able to modify pretty much everything of the forms in the templates - this seems to be the right way of doing this.

(Sorry, I had to split two of the links b/c I don't have enough reputation to post more than two links. Sad.)

CptSadface's answer was what helped me with translating my entity choices.

$builder
    ->add(
        'authorizationRoles',
        null,
        [
            'label' => 'app.user.fields.authorization_roles',
            'multiple' => true,
            'choice_label' => 'name', // entity field storing your translation key
            'choice_translation_domain' => 'messages',
        ]
    );
