问题
I need to translate validation message.
I found this link
https://zendframework.github.io/zend-validator/messages/
In my global config I have this
'translator' => [
'locale' => ['it_IT','en_US'],
'translation_file_patterns' => [
[
'type' => 'gettext',
'base_dir' => getcwd() . '/data/language',
'pattern' => '%s.mo',
],
],
],
In the view translator , using __('key'), work fine. But validation message remain in english
I used the site's guide to validate the form this is my code
<?php
namespace Admin\Model;
// Add the following import statements:
use DomainException;
use Zend\Filter\StringTrim;
use Zend\Filter\StripTags;
use Zend\Filter\ToInt;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
use Zend\Validator\NotEmpty;
use Zend\Validator\StringLength;
class LoginModel implements InputFilterAwareInterface
{
public $username;
public $user2;
private $inputFilter;
.....
public function getInputFilter()
{
if ($this->inputFilter) {
return $this->inputFilter;
}
$inputFilter = new InputFilter();
$inputFilter->add([
'name' => 'username',
'required' => true,
'validators' => [
[
'name' => NotEmpty::class
],
],
]);
$inputFilter->add([
'name' => 'user2',
'required' => true,
'validators' => [
[
'name' => NotEmpty::class,
],
],
]);
$this->inputFilter = $inputFilter;
return $this->inputFilter;
}
}
Where I put the code of the link above?
Answer to comment
I readed a zend i18n validator doc. But I don't understand where put this code. I've more form to validate
$translator = new Zend\Mvc\I18n\Translator();
$translator->addTranslationFilePattern(
'phpArray',
Resources::getBasePath(),
Resources::getPatternForValidator()
);
AbstractValidator::setDefaultTranslator($translator);

You can add the messages in the options of a validator. Like so:
$inputFilter->add([
'name' => 'user2',
'required' => true,
'validators' => [
[
'name' => NotEmpty::class,
'options' => [
'messages' => [
'messageKey' => 'non-translated message',
'messageKey2' => _('translated message'),
],
],
],
],
]);
To overwrite the message of Zend, you might wish to use the constants used in the Validators instead. E.g. your question uses the NotEmpty validator. If you have a look at that class, you'll find:
/**
* @var array
*/
protected $messageTemplates = [
self::IS_EMPTY => "Value is required and can't be empty",
self::INVALID => "Invalid type given. String, integer, float, boolean or array expected",
];
So, when you define custom messages like I've shown above, you'd best do:
'messages' => [
NotEmpty::IS_EMPTY => 'non-translated message',
NotEmpty::INVALID => _('translated message'),
],
Please note: You do not need to translate all of ZF's default messages, unless the language you want is not supported, of course. More info
zend-validator is shipped with more than 45 different validators with more than 200 failure messages. It can be a tedious task to translate all of these messages. For your convenience, pre-translated messages are provided in the zendframework/zend-i18n-resources package
Supported languages of that repo here
Additional question added to question of where to place config to enable translator + translations
To make sure that the translator knows where to find translation files, add the following to each module in the module.config.php:
'translator' => [
'translation_file_patterns' => [
[
'type' => 'gettext', // This uses the php-gettext module
'base_dir' => __DIR__ . '/../language', // Where the folder with files is in relation to this config file
'pattern' => '%s.mo', // Update extension for what you use
],
],
],
For this to be used you must have a Translator package installed. I would recommend you use the Zend Mvc i18n package.
Enable it in your config/modules.config.php file by adding the namespace to the module array: 'Zend\\Mvc\\I18n',
Add and install the module via the composer.json by adding it to your require list. Current version at time of writing included:
"zendframework/zend-mvc-i18n": "^1.1"
To make sure it'll work in the future, it's a good idea to add these to the require as well:
"ext-intl":"*",
"ext-gettext":"*",
The above will require that the intl and gettext PHP Modules are installed in the currently running PHP instance.

Ok i found solution to problem especially thanks to the support of Rkeet(thanks).
The documentation have some imprecision.
This row
$translator = new Zend\Mvc\I18n\Translator();
generates an error because constructor require parameter. I did change the row in this way:
$translator = $e->getApplication()->getServiceManager()->get('MvcTranslator');
Then i realize that translator search in this directory
vendor\zendframework\zend-i18n-resources\src/../languages/
for locale it_IT
In that path there isn't it_IT folder but only "it". I did rename it and all work fine.
Below complete code of my Module.php file
<?php
namespace Admin;
use Zend\I18n\Translator\Resources;
use Zend\Validator\AbstractValidator;
use Zend\Mvc\MvcEvent;
class Module
{
const VERSION = '3.0.3-dev';
public function onBootstrap(MvcEvent $e)
{
/** @var \Zend\Mvc\I18n\Translator $translator */
$translator = $e->getApplication()->getServiceManager()->get('MvcTranslator');
$translator->addTranslationFilePattern(
'phpArray',
Resources::getBasePath(),
Resources::getPatternForValidator()
);
AbstractValidator::setDefaultTranslator($translator);
}
public function getConfig()
{
return include __DIR__ . '/../config/module.config.php';
}
}

If you want to use default ZF3 translations for validation message you have to modify the "Module.php" file under "src" folder.
First of all install the "zend-mvc-i18n" module via composer using "require" command:
composer require zendframework/zend-mvc-i18n
Then use this code in "Module.php" for example to view validation message in italian language:
<?php
namespace Application;
use Zend\I18n\Translator\Resources;
use Zend\Mvc\I18n\Translator;
use Zend\I18n\Translator\Translator as I18nTranslator;
use Zend\Validator\AbstractValidator;
use Zend\Mvc\MvcEvent;
use Zend\Mvc\ModuleRouteListener;
class Module
{
const VERSION = '3.0.3-dev';
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
$t = new I18nTranslator();
$t->setLocale('it_IT');
$translator = new Translator($t);
$translator->addTranslationFile('phpArray', 'vendor/zendframework/zend-i18n-resources/languages/it/Zend_Validate.php', 'default', 'it_IT');
AbstractValidator::setDefaultTranslator($translator);
}
}
You can change "it_IT" to "es_ES" or "de_DE" to view validation message in other languages.
