I am developing a Zend Framework 2 Application and now I want to implement a language switcher from where guest/registered user can choose the language they want, the thing I can't understand is how is it made in Zend Framework 2 using the storage ( not from urls ), I want to keep the preffered language of guest in the storage once he selects one, and for the registered users I can retrieve the preffered one from cookie/database and reuse it with storage. But where and how should I start/implement this? Thank you in advance.

Setup your
Locales
in yourglobal.config.php
:'locale' => array( 'default' => 'en_US', 'available' => array( 'de_DE' => 'Deutsch', 'nl_NL' => 'Dutch', 'en_US' => 'English', 'fr_FR' => 'French', ), ),
So in your
Application\Module.php
you can add a method which sets the defaultZend\Translator\Translator
:class Module { public function onBootstrap(MvcEvent $e) { $applicaton = $e->getApplication(); $serviceManager = $application->getServiceManager(); // Just a call to the translator, nothing special! $serviceManager->get('translator'); $this->initTranslator($e); // Etc, more of your bootstrap function. } protected function initTranslator(MvcEvent $event) { $serviceManager = $event->getApplication()->getServiceManager(); // Zend\Session\Container $session = New Container('language'); $translator = $serviceManager->get('translator'); $translator ->setLocale($session->language) ->setFallbackLocale('en_US'); } }
So now the default Locale is en_US as the session has no Locale available. For changing the locale you need to catch the users input and validate the available locales you support, provided in your
global.config.php
. So in order to change it you might need to add a controller action which catches the input of the user and sets the new locale. Example of the controller action without any form usage!public function changeLocaleAction() { // New Container will get he Language Session if the SessionManager already knows the language session. $session = new Container('language'); $language = $this->getRequest()->getPost()->language; $config = $this->serviceLocator->get('config'); if (isset($config['locale']['available'][$language]) { $session->language = $language; $this->serviceLocator->get('translator')->setLocale($session->language); } }
The session allows the users to change their locale and remember it until the session ends, so they won't need to change it when they get back after a while. Hope this will help you and can help you to write some code to save it for your registered users on your application.
