ZF2 - How To Translate Zend Form Validation Error Messages? - php

Question

I have the .po and compiled .mo language files for diffrent languages.
But language translation is not working on zend form validation error messages.
I dont want to use extra .php file like fr.php for it.
I got this code from click here
$translator = new Zend\I18n\Translator\Translator();
$translator->addTranslationFile(
'phpArray'
'resources/languages/en.php',
'default',
'en_US'
);
Zend\Validator\AbstractValidator::setDefaultTranslator($translator);
Any solution how to implement it in ZF2.

I do not approve of the selected answer :P
When adding a new translator to your configuration, do NOT use the default translator-text-domain. The Syntax is as follows:
$translator->addTranslationFile(
$type,
$resource,
$textDomain, //<-- this is the important one
$lang
);
In your example you've added a file to the default-textdomain. This, sadly, brings lots of troubles with it, at it will not always work as expected. Whenever you're adding translation files, add them to your own text-domain!
After that, all you need to do is to assign the Zend\Form\View\Helper your text-domain. This is done by the following:
// For Labels
$this->formLabel()->setTranslatorTextDomain('your-textdomain');
// For Buttons (input type submit)
$this->formButton()->setTranslatorTextDomain('your-textdomain');
// For Error-Messages
$this->formElementErrors()->setTranslatorTextDomain('your-textdomain');
How to get the ServiceManager into the Form?
This is pretty easy, too. The simples one is to use constructor-injection and inject the ServiceManager or ServiceLocator into the __construct() of your Form. On a Controller-Level this would look something like this:
$serviceLocator = $this->getServiceLocator();
$form = new My\Form($serviceLocator);
A more in-depth introduction to Form-Dependencies can be found on my Blog, where i illustrate the population of a Zend\Form\Element\Select-Element on dependent Database-Connections.
About the Translator itself
Another thing to note is: as long as there is a Translator-Service attached to your configuration with the name translator, it will automatically be attached to the form as default translator. This is a sample configuration i use within my modules regularly:
'translator' => array(
'locale' => 'de_DE',
'translation_file_patterns' => array(
array(
'type' => 'phparray',
'base_dir' => __DIR__ . '/lang',
'pattern' => '%s.php',
'text_domain' => __NAMESPACE__,
),
),
),

Simply add your .po or .mo files instead of the .php ones, i.e. like this:
$translator = new Zend\I18n\Translator\Translator();
$translator->addTranslationFile(
'gettext'
'resources/languages/fr.mo',
'default',
'fr_FR'
);
Zend\Validator\AbstractValidator::setDefaultTranslator($translator);
And then to translate it, use
echo $this->formElementErrors($form->get("username"),
array('message' => $this->translate("errormessage"))
);
I don't know how it is with performance of the translation in ZF2, but in ZF1 using arrays in .php files was way faster than any other method.
