Filament Translate Field

Filament Translate Field is a library for Filament CMS that simplifies managing multiple translatable fields in different languages.

Installation

You can install the package via composer:

composer require solution-forest/filament-translate-field

Important

• There's a conflict with the Translatable trait in the filament/spatie-laravel-translatable-plugin when used on the EditPage. Avoid using Translatable while editing.

Configuration:

• Define translatable fields in your model using a translatable package (e.g., "spatie/laravel-translatable" or "dimsav/laravel-translatable").
• Configure translatable fields in the model's $translatable property.

Setup

For version before 1.x.x

Adding the plugin to a panel

To add a plugin to a panel, you must include it in the configuration file using the plugin() method:

use SolutionForest\FilamentTranslateField\FilamentTranslateFieldPlugin;
 
public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugin(FilamentTranslateFieldPlugin::make());
}

Setting the default translatable locales

To set up the locales that can be used to translate content, you can pass an array of locales to the `defaultLocales()` plugin method:

use SolutionForest\FilamentTranslateField\FilamentTranslateFieldPlugin;
 
public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugin(
            FilamentTranslateFieldPlugin::make()
               ->defaultLocales(['en', 'es', 'fr']),
        );
}

For version equal or after 1.x.x

Setting the default translatable locales

Since the plugin after 1.x.x is a standalone plugin, which does not need to be related to Filament Panel, so you need to globally set it up in the config file or use the boot method in `AppServiceProvider`.

To set up the locales that can be used to translate content, you can pass an array of locales to the `defaultLocales()` plugin method:

use SolutionForest\FilamentTranslateField\Facades\FilamentTranslateField;
 
class AppServiceProvider extends ServiceProvider
{
   public function boot(): void
   {
       FilamentTranslateField::defaultLocales(['en', 'es', 'fr']);
   }
}

Or, you can publish configuration file config/filament-translate-field.php and add default locales on locales:

return [
    'locales' => ['en', 'es', 'fr'],
];

Usage

Form component

By using the Translate component, you can easily configure your form fields to support multiple languages and provide translations for each locale.

use Filament\Forms\Components\TextInput;
use Filament\Forms\Components\Textarea;
use Filament\Forms\Components\RichEditor;
use SolutionForest\FilamentTranslateField\Forms\Component\Translate;

Translate::make()
    ->schema([
         // Your form fields here
    ])

Setting the translatable locales for a particular fields

By default, the translatable locales can be set globally for all translate form component in the plugin configuration. Alternatively, you can customize the translatable locales for a particular resource by overriding the locales() method in Translate class:

use SolutionForest\FilamentTranslateField\Forms\Component\Translate;

Translate::make()->locales(['en', 'es'])

Label

Setting the translatable label for a particular field

You have the flexibility to customize the translate label for each field in each locale. You can use the fieldTranslatableLabel() method to provide custom labels based on the field instance and the current locale.

use SolutionForest\FilamentTranslateField\Forms\Component\Translate;

 Translate::make()
    ->schema([
        // Fields
    ])
    ->fieldTranslatableLabel(fn ($field, $locale) => __($field->getName(), locale: $locale))

Adding prefix/suffix locale label to the field

If you simply want to add a prefix or suffix locale label to the form field, you can use the prefixLocaleLabel() or suffixLocaleLabel() method. This makes it easier for users to identify the language associated with each field.

use SolutionForest\FilamentTranslateField\Forms\Component\Translate;

Translate::make()
    ->schema([
        // Fields
    ])
    ->prefixLocaleLabel()
    ->suffixLocaleLabel()

`prefixLocaleLabel:

suffixLocaleLabel:

Setting the locale display name

By default, the prefix/suffix locale display name is generated by locale code and enclosed in parentheses, "()". You may customize this using the preformLocaleLabelUsing() method:

use SolutionForest\FilamentTranslateField\Forms\Component\Translate;

Translate::make()
    ->preformLocaleLabelUsing(fn (string $locale, string $label) => "[{$label}]");

Injecting the current form field

Additionally, if you need to access the current form field instance, you can inject the $field parameter into the callback functions. This allows you to perform specific actions or conditions based on the field being processed.

use Filament\Forms\Components\Component;
use SolutionForest\FilamentTranslateField\Forms\Component\Translate;

Translate::make()
    // ...
    ->prefixLocaleLabel(function(Component $field) {
        // need return boolean value
        return $field->getName() == 'title';
    })
    ->suffixLocaleLabel(function(Component $field) {
        // need return boolean value
        return $field->getName() == 'title';
    })

Adding action

You may add actions before each container of children components using the actions() method:

use Filament\Forms\Components\Actions\Action;
use SolutionForest\FilamentTranslateField\Forms\Component\Translate;

Translate::make()
    ->actions([
        Action::make('fillDumpTitle')
    ])

If have multiple Translate components and have action in each component, please add id to Translate component by id() method

Injecting the locale on current child container

If you wish to access the locale that have been passed to the action, define an $arguments parameter and get the value of locale from $arguments:

use Filament\Forms\Components\Actions\Action;
use SolutionForest\FilamentTranslateField\Forms\Component\Translate;

Translate::make()
    ->actions([
        Action::make('fillDumpTitle')
            ->action(function (array $arguments) {
                $locale = $arguments['locale'];
                // ...
            })
    ])

Injecting the locale to form field

If you wish to access the current locale instance for the field, define a $locale parameter:

use Filament\Forms\Components\TextInput;
use SolutionForest\FilamentTranslateField\Forms\Component\Translate;

Translate::make()
    ->schema(fn (string $locale) => [TextInput::make('title')->required($locale == 'en')])

Removing the styled container

By default, translate component and their content are wrapped in a container styled as a card. You may remove the styled container using contained():

use SolutionForest\FilamentTranslateField\Forms\Component\Translate;
 
Translate::make()
    ->contained(false)

Exclude

The exclude feature allows you to specify fields that you don't want to be included in the translation process. This can be useful for fields that contain dynamic content or that shouldn't be translated into other languages.

use SolutionForest\FilamentTranslateField\Forms\Component\Translate;
 
Translate::make([
        Forms\Components\TextInput::make('title'),
        Forms\Components\TextInput::make('description'),
    ])
    ->exclude(['description'])

Without exclude

{
    "title": {
        "en": "Dump",
        "es": "Dump",
        "fr": "Dump"
    },
    "description": {
        "en": null,
        "es": null,
        "fr": null
    }
}

With Exclude

{
    "title": {
        "en": "Dump",
        "es": "Dump",
        "fr": "Dump"
    },
    "description": null
}

Publishing Views

php artisan vendor:publish --provider="SolutionForest\\FilamentTranslateField\\FilamentTranslateFieldServiceProvider" --tag="filament-translate-field-views"

Publishing Configuration file

    public $translatable = ['title', 'short_desc', 'description'];

    public $casts = [
        'title' => 'json',
        'short_desc' => 'json',
        'description' => 'json',

    // ...
}

In resources/lang/en.json:

{
    "title": "Title",
    "short_desc": "Short description",
    "description": "Description"
}

In resources/lang/es.json:

{
    "title": "Título",
    "short_desc": "Breve descripción",
    "description": "Descripción"
}

In resources/lang/fr.json:

{
    "title": "Titre",
    "short_desc": "Brève description",
    "description": "Description"
}

In the given example, when you save the model, the data will be stored in the following format:

{
  "id": 1,
  "title": {
    "en": "Dump",
    "es": "Dump",
    "fr": "Dump"
  },
  "short_desc": {
    "en": null,
    "es": null,
    "fr": null
  },
  "description": {
    "en": null,
    "es": null,
    "fr": null
  }
