ZF 2 Form Validation Translations - zend-framework

Question

I use ZF 2.4 and I would like to change form validation messages to German, so I used code compatible with doc - https://framework.zend.com/manual/2.4/en/modules/zend.validator.messages.html
$translator = new \Zend\Mvc\I18n\Translator();
$translator->addTranslationFile(
'phpArray',
'./vendor/zendframework/zendframework/resources/languages/en/Zend_Validate.php', //or Zend_Captcha
'default',
'de_DE'
);
\Zend\Validator\AbstractValidator::setDefaultTranslator($translator);
Unfortunatelly EN is used still.. For example message "Value is required and can't be empty" is displayed from vendor/zendframework/zendframework/library/Zend/Validator/NotEmpty.php and isn't translated from vendor/zendframework/zendframework/resources/languages/de/Zend_Validate.php
No errors are there...
Could somebody help me, please? This is very important for me...

Answer 1

The translator is still pointing to the Locale of EN. What you want to do is set the translator Locale based on the user settings or maybe even a route parameter. To do that use the setLocale($locale) on your Translator.
So you could do this within your Application\Module.php:
$language = $event->getRouteMatch()->getParam('language', 'en_US');
$serviceManager = $event->getApplication()->getServiceManager();
$translator = $serviceManager->get('translator');
$translator
->setLocale($language)
->setFallbackLocale('en_US')
->addTranslationFilePattern(
'phpArray',
\Zend\I18n\Translator\Resources::getBasePath(),
\Zend\I18n\Translator\Resources::getPatternForValidator()
);
AbstractValidator::setDefaultTranslator($translator);
It is up to you to where you get the language locale from. If you don't have a route param defined for the language but want to use the user settings for example:
$language = 'en_US';
$authService = $auth = $serviceManager->get('zfcuser_auth_service');
if ($authService->hasIdentity()) {
$language = $authService->getIdentity()->getUserSettings()->getLanguage();
}

Haa, it works when I used below code:
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
$serviceManager = $e->getApplication()->getServiceManager();
$translator = $serviceManager->get('translator');
//$locale = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
$locale = 'de_DE';
//$locale = 'en_US';
$translator->setLocale(\Locale::acceptFromHttp($locale));
$translator->addTranslationFile(
'phpArray',
'./vendor/zendframework/zendframework/resources/languages/de/Zend_Validate.php',
'default',
'de_DE'
);
\Zend\Validator\AbstractValidator::setDefaultTranslator($translator);
}
I don't understand why it wasn't working before..
