This Filament plugin provides an integration for the spatie/laravel-translatable package.

It can easily be combined with the lara-zeus/translatable package as our package only provides the Form integration. To do so, simply remove all lara-zeus specific code from the Create and Edit pages of your Filament Resources.

Instead of rendering a dropdown to select the locale, it wraps the translatable fields in a Tabs component for a better user experience.

⚠️ Caution: V4 is a complete rewrite of the package and logic. Please take a look at the installation instructions below!

#Installation

You can install the package via composer:

composer require outerweb/filament-translatable-fields

Add the plugin to your panel:

use Outerweb\FilamentTranslatableFields\TranslatableFieldsPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugins([
            // ...
            TranslatableFieldsPlugin::make(),
        ]);
}

#Configuration

#Supported locales

By default, the package will try to read out the supported locales from the config/app.php file. It will check for app.supported_locales first and then fallback to app.locales and app.fallback_locale.

You can manually configure the supported locales like this:

use Outerweb\FilamentTranslatableFields\TranslatableFieldsPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugins([
            // ...
            TranslatableFieldsPlugin::make()
                ->supportedLocales(['en', 'de', 'fr']),
        ]);
}

If you want to provide custom labels for the locales, you can do it like this:

use Outerweb\FilamentTranslatableFields\TranslatableFieldsPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugins([
            // ...
            TranslatableFieldsPlugin::make()
                ->supportedLocales([
                    'en' => 'English',
                    'de' => 'Deutsch',
                    'fr' => 'Français',
                ]),
        ]);
}

If you want to dynamically provide the supported locales, you can also pass a Closure to the supportedLocales() method:

use Outerweb\FilamentTranslatableFields\TranslatableFieldsPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugins([
            // ...
            TranslatableFieldsPlugin::make()
                ->supportedLocales(fn () => getSupportedLocales()),
        ]);
}

#Default locale

By default, the active tab will be the one of the app's locale when rendering the form. You can change this behavior by setting a default locale:

use Outerweb\FilamentTranslatableFields\TranslatableFieldsPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugins([
            // ...
            TranslatableFieldsPlugin::make()
                ->defaultLocale('de'),
        ]);
}

If you want to dynamically provide the default locale, you can also pass a Closure to the defaultLocale() method:

use Outerweb\FilamentTranslatableFields\TranslatableFieldsPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugins([
            // ...
            TranslatableFieldsPlugin::make()
                ->defaultLocale(fn () => auth()->user()->preferred_locale),
        ]);
}

#Usage

#Marking single fields as translatable

To mark a single field as translatable, you can use the translatable() method on any Filament form field:

use Filament\Forms\Components\TextInput;

TextInput::make('name')
    ->translatable(),

This will wrap the field in a Tabs component with a tab for each supported locale.

Note: Make sure to place the translatable() method at the end of the field definition to avoid any unexpected behavior.

#Modifying/Validating a field for a specific locale

All modifiers and validation rules applied before calling the translatable() method will be applied field for each locale. If you want to apply a modifier or validation rule for a specific locale only, you can use the modifyLocalizedFieldUsing parameter in the translatable() method:

use Filament\Forms\Components\TextInput;

TextInput::make('name')
    ->translatable(
        modifyLocalizedFieldUsing: function (TextInput $field, string $locale): TextInput {
            return match ($locale) {
                'en' => $field->required(),
                default => $field,
            };
        },
    ),

#Conditionally marking a field as translatable

You can also conditionally mark a field as translatable by passing a bool or Closure to the translatable() method:

use Filament\Forms\Components\TextInput;

// Using a bool
TextInput::make('name')
    ->translatable(false),

// Using a Closure
TextInput::make('name')
    ->translatable(fn () => someCondition()),

#Overriding the supported locales for a single field

You can override the supported locales for a single field by passing an array or Closure to the translatable() method:

use Filament\Forms\Components\TextInput;

// Using an array
TextInput::make('name')
    ->translatable(
        supportedLocales: ['en', 'de']
    ),

// Using a Closure
TextInput::make('name')
    ->translatable(
        supportedLocales: fn () => getSupportedLocales(),
    ),

#Overriding the default locale for a single field

You can override the default locale for a single field by passing a string or Closure to the translatable() method:

use Filament\Forms\Components\TextInput;

// Using a string
TextInput::make('name')
    ->translatable(
        defaultLocale: 'de'
    ),

// Using a Closure
TextInput::make('name')
    ->translatable(
        defaultLocale: fn () => auth()->user()->preferred_locale,
    ),

#Marking a group of fields as translatable

You can also mark a Layout component as translatable. This will make all fields inside the layout translatable:

use Filament\Schemas\Components\Section;

Section::make()
    ->schema([
        TextInput::make('name'),
        TextInput::make('description'),
    ])
    ->translatable(),

This will wrap all fields inside the layout in a Tabs component with a tab for each supported locale.

Note: Make sure to place the translatable() method at the end of the component definition to avoid any unexpected behavior.

All the options described for single fields (modifying/validating a field for a specific locale, conditionally marking as translatable, overriding supported/default locales) are also available when marking a layout component as translatable.

For modifying/validating fields inside a layout component, the provided Closure will be called for each field inside the layout.

Example:

use Illuminate\Support\Str;
use Filament\Forms\Components\TextInput;
use Filament\Schemas\Components\Component;
use Filament\Schemas\Components\Section;

Section::make()
    ->schema([
        TextInput::make('name'),
        TextInput::make('description'),
    ])
    ->translatable(
        modifyLocalizedFieldUsing: function (Component $field, string $locale): Component {
            if ($field instanceof TextInput && Str::startsWith($field->getName(), 'name.')) {
                return match ($locale) {
                    'en' => $field->required(),
                    default => $field,
                };
            }

            return $field;
        },
    ),
