Installation

1. Install the package via Composer:

composer require craft-forge/filament-language-switcher

2. Register the plugin in your Filament panel configuration (e.g. AdminPanelProvider):

use CraftForge\FilamentLanguageSwitcher\FilamentLanguageSwitcherPlugin;

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

The plugin will automatically detect available Filament language files and display them in a dropdown menu.

Configuration

Locales

By default, the plugin auto-detects available Filament language files. To define the locale list manually, pass it to locales() - choose one of three formats:

Locale codes - names and flags are resolved automatically from the built-in dictionary (200+ languages):

FilamentLanguageSwitcherPlugin::make()
    ->locales(['en', 'fr', 'de'])

Full control - specify name and flag per locale. Flag codes reference: https://flagicons.lipis.dev.

FilamentLanguageSwitcherPlugin::make()
    ->locales([
        ['code' => 'en', 'name' => 'English', 'flag' => 'us'],
        ['code' => 'fr', 'name' => 'Français', 'flag' => 'fr'],
        ['code' => 'de', 'name' => 'Deutsch', 'flag' => 'de'],
    ])

Dynamic - load locales at runtime (e.g. from a database):

FilamentLanguageSwitcherPlugin::make()
    ->locales(fn () => Language::pluck('code')->toArray())

Remember Locale

Store the selected locale in a cookie to persist across browser sessions (e.g. after logout):

FilamentLanguageSwitcherPlugin::make()
    ->rememberLocale()          // forever
    ->rememberLocale(days: 30)  // for 30 days

Custom Render Hook

Change where the language switcher appears in the panel:

use Filament\View\PanelsRenderHook;

FilamentLanguageSwitcherPlugin::make()
    ->renderHook(PanelsRenderHook::USER_MENU_PROFILE_AFTER)

Popular placements:

• USER_MENU_BEFORE — before the user menu (default)
• USER_MENU_PROFILE_AFTER — after user profile in dropdown
• USER_MENU_AFTER — after the user menu
• SIDEBAR_FOOTER — at the bottom of sidebar
• FOOTER — in the page footer

All available render hooks: https://filamentphp.com/docs/5.x/advanced/render-hooks

Show on Auth Pages

Display the language switcher on login, register, and password reset pages:

FilamentLanguageSwitcherPlugin::make()
    ->showOnAuthPages()

Hide Flags

Display only language names without flag icons:

FilamentLanguageSwitcherPlugin::make()
    ->showFlags(false)

Event

The plugin dispatches a LocaleChanged event whenever a user switches locale, providing both the new and previous locale:

use CraftForge\FilamentLanguageSwitcher\Events\LocaleChanged;
use Illuminate\Support\Facades\Event;

public function boot(): void
{
    Event::listen(LocaleChanged::class, function (LocaleChanged $event) {
        // auth()->user()->setLocale($event->newLocale);
        // Log::info("Locale changed from {$event->oldLocale} to {$event->newLocale}");
    });
}
