// Symfony >= 3.4. Add in your app/config/config.yml:

a2lix_translation_form:
    locale_provider: default       # [1]
    locales: [en, fr, es, de]      # [1-a]
    default_locale: en             # [1-b]
    required_locales: [fr]         # [1-c]

5. Additional

TranslationsFormsType

A different approach for entities which don't share fields untranslated. No strategy used here, only a locale field in your entity.

use A2lix\TranslationFormBundle\Form\Type\TranslationsFormsType;
...
$builder->add('translations', TranslationsFormsType::class, [
    'locales' => ['en', 'fr', 'es', 'de'],   // [1]
    'default_locale' => ['en']               // [1]
    'required_locales' => ['fr'],            // [1]
    'form_type' => ProductMediaType::class,     // [2 - Mandatory]
    'form_options' => [                         // [2bis]
         'context' => 'pdf'
    ]
]);

• [1] Optional. If set, override the default value from config.yml
• [2] Mandatory. A real form type that you have to do
• [2bis] Optional. - An array of options that you can set to your form

TranslatedEntityType

Modified version of the native 'entity' symfony form type to translate the label in the current locale by reading translations

use A2lix\TranslationFormBundle\Form\Type\TranslatedEntityType;
...
$builder->add('medias', TranslatedEntityType::class, [
    'class' => 'A2lix\DemoTranslationBundle\Entity\Media',   // [1 - Mandatory]
    'translation_property' => 'title',                           // [2 - Mandatory]
    'multiple' => true,                                             // [3]
));

• [1] Path of the translatable class
• [2] Property/Method of the translatable class that will be display
• [3] Common options of the 'entity' Symfony form type (multiple, ...)
