README

This plugin provides tools for internationalization in CakePHP 5:

I18nRoute – generate and match routes with language prefixes (/{lang}/{controller}/{action}).

I18nMiddleware – automatically sets locale via I18n::setLocale() based on URL prefix and optionally redirects root / to default or browser-detected language.

DbMessagesLoader – load translation messages from the database instead of .po/.mo files.

Validation translation – auto-translate validation messages.

TimezoneWidget – generate a box of timezones grouped by region. Installation composer require zvezda/cakephp-i18n Usage Load Plugin In CakePHP 5, use Application.php to load plugins: // src/Application.php public function bootstrap(): void { parent::bootstrap(); $this->addPlugin(\ADmad\I18n\Plugin::class); } I18nRoute Define routes with language prefix: use ADmad\I18n\Routing\I18nRoute; $routes->scope('/', function ($routes) { $routes->connect( '/{controller}', ['action' => 'index'], ['routeClass' => I18nRoute::class] ); $routes->connect( '/{controller}/{action}/*', [], ['routeClass' => I18nRoute::class] ); }); Set supported languages in config/app.php: return [ 'I18n' => [ 'languages' => ['en', 'fr', 'de'] ] ]; I18nMiddleware Configure middleware in Application::middleware(): use ADmad\I18n\Middleware\I18nMiddleware; $middlewareQueue->add(new I18nMiddleware([ 'detectLanguage' => true, 'defaultLanguage' => 'en', 'languages' => [ 'en' => ['locale' => 'en_US'], 'fr' => ['locale' => 'fr_FR'], ], ])); Notes: Add after RoutingMiddleware. Configure a root route / to prevent missing route errors: $routes->connect('/', ['controller' => 'Pages', 'action' => 'display', 'home']); DbMessagesLoader Store translation messages in the database instead of .po files. Create i18n_messages table using the SQL file in config/. Configure loader in config/bootstrap.php: use ADmad\I18n\I18n\DbMessagesLoader; use Cake\I18n\I18n; I18n::config('default', function ($domain, $locale) { $loader = new DbMessagesLoader($domain, $locale); return $loader(); }); Extract messages from code: bin/cake admad/i18n extract --languages en,fr,de TimezoneWidget Register in AppView: $this->loadHelper('Form', [ 'widgets' => [ 'timezone' => ['ADmad/I18n.Timezone'], ], ]); Use in forms: // Full timezone list $this->Form->control('field', ['type' => 'timezone']); // Specific regions $this->Form->control('field', [ 'type' => 'timezone', 'options' => [ 'Asia' => DateTimeZone::ASIA, 'Europe' => DateTimeZone::EUROPE, ], ]);
