Branch	Tools
3.x (master)

Screenshot example

Support

• 3.x depends on AutoFormBundle and has higher requirements (PHP8.1+, Symfony5.4+/6.3+/7.0+). It is compatible with KnpLabs, A2lix and Prezent

Installation

Use composer:

composer require a2lix/translation-form-bundle

After the successful installation, add/check the bundle registration:

// Symfony >= 4.0 in bundles.php
// ...
A2lix\AutoFormBundle\A2lixAutoFormBundle::class => ['all' => true],
A2lix\TranslationFormBundle\A2lixTranslationFormBundle::class => ['all' => true],
// ...

// Symfony >= 3.4 in AppKernel::registerBundles()
$bundles = array(
// ...
new A2lix\AutoFormBundle\A2lixAutoFormBundle(),
new A2lix\TranslationFormBundle\A2lixTranslationFormBundle(),
// ...

Configuration

There is no minimal configuration. Full list of optional parameters:

# Symfony >= 4.0. Create a dedicated a2lix.yaml in config/packages with:
# 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]
    templating: "@A2lixTranslationForm/bootstrap_4_layout.html.twig"      # [2]

1. Custom locale provider service id. Default one relies on [1-*] values:
   • [1-a] List of translations locales to display
   • [1-b] Default locale
   • [1-c] List of required translations locales
2. The default template is Twitter Bootstrap compatible. You can redefine your own here

Usage

use A2lix\TranslationFormBundle\Form\Type\TranslationsType;
...
$builder->add('translations', TranslationsType::class);

            'locale_options' => [                  // [3.b]
                'es' => ['label' => 'descripción'],    // [4]
                'fr' => ['display' => false]           // [4]
            ]
        ]
    ],
    'excluded_fields' => ['details'],           // [2]
    'locale_labels' => [                        // [5]
        'fr' => 'Français',
        'en' => 'English',
    ],

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, ...)
