KNP Menu Bundle Translation Domain

Question

I'm using Symfony 2.3 and the KnpMenuBundle.

Is it possible to use a translation domain for menu items?

Like this:

$menu['management']->addChild(
    'msg.user.list',
    array(
        'route' => 'user_list',
        'translation_domain' => 'navigation'
    )
);

1. According to the Symfony documentation and KnpMenuBundle documentation,you may set the translation domain (menu in my snippets), while adding menu items in your MenuBuilder class:

   $menu->addChild('Home', array('route' => 'homepage'))
        ->setExtra('translation_domain', 'menu');
   

2. You may better want to add the translation domain into the whole menu instead:

   $menu = $this->factory->createItem('root')
                ->setExtra('translation_domain', 'menu');
   

3. Then create a file named knp_menu.html.twig in:

   app/Resources/views/menu/
   

4. and put this in it:

   {% extends 'knp_menu.html.twig' %}
   
   {% block label %}
       {% if options.allow_safe_labels and item.getExtra('safe_label', false) %}
           {{ item.label | raw | trans(item.getExtra('translation_params', {}), item.getExtra('translation_domain', 'menu'))}}
       {% else %}
           {{ item.label | trans(item.getExtra('translation_params', {}), item.getExtra('translation_domain', 'menu')) }}
       {% endif %}
   {% endblock %}
   

   (If the file already exists, just replace the {% block label %}{% endblock %} part)

5. Be carefull to have translation files (.xliff or whatever) naming strategy like:

   {translation_domain}.{locale}.{extenstion}
   

   for example:

   menu.fa.xliff
   

   In this path:

   app/Resources/translations/
   

6. The last part is:

   # app/config/config.yml
   knp_menu:
       twig:
           template: knp_menu.html.twig
