Automatic translation of legends

[greg-man]

I have a form to which I pass a translation_domain as parameter.

Am I missing something or could it truely be that the legend titles won't be translated automatically?

To be honest, I've never tried it. Perhaps you could share some code and I can try and help. Also, which version of symfony are you using because it appears the recommended way of setting it changes slightly in 2.7?

Sure. As I work with a form that is not tied to an entity I just call (using Symfony 2.7)

$this->createFormBuilder(null, [ 'translation_domain' => $domain ])
    ->add('first', 'fieldset', [
        'label' => false,
        'legend' => 'form.first_fieldset', // is not translated and ignores translation domain
        'fields' => [
            [
                'name'  => 'first_name',
                'type'  => 'text',
                'attr'  => [
                    'label' => 'form.first_name' // is translated properly respecting translation domain
                ]
            ],
            [
                'name'  => 'last_name',
                'type'  => 'text',
                'attr'  => [
                    'label'     => 'form.last_name' / // is translated properly respecting translation domain
                    ]
                ]
            ]
        ]);

Just saw that legend variable in fieldset.html.twig misses the trans modifier. Adding it (see the example beneath) makes translations work, but still ignores the passed translation domain.

{% block fieldset_widget %}
    <fieldset {{ block('widget_container_attributes') }}>

        {% if legend is defined and legend is not empty %}
            <legend>{{ legend | trans }}</legend>
        {% endif %}
        {{ form_widget(form) }}

    </fieldset>
{% endblock %}

I've never tried the translation domain using this bundle, but you could try setting translation_domain in each attr key as these will be passed to the underlying types.

You could also try creating a form class for this form and then setting it as a default option. http://stackoverflow.com/a/18096325
