I’m currently setting up some forms using Zend. I’m using the FormFilter class to validate the forms.
The default error messages are pretty dry, so I’d like to make them more readable.
The problem is that I have over 13 forms, and with 4 or 5 inputs on each form, I don’t really want to have to set the error message per input. This stock overflow post seemed useful (http://stackoverflow.com/questions/459921/zend-form-nicely-change-setrequired-validate-message), but I’m guessing its based on zf1, because some of the classes don’t seem to be present, or have changed.
In fact I have found that whenever I call a call with Zend as a prefix, like Zend_Validate_Abstract, I get an error message telling me the class does not exists. I have to call it like so: Zend\Validator\AbstractValidator.
I’m not sure if this is the best method of doing things in Zend, but its the method they used in the tutorials on their site.
Edit: Reading through the Stack Overflow question you linked to, I see one of the answers (by John B) makes a similar suggestion. Perhaps the manual page will enable you to update the code to work with ZF2.
$translateValidators = array(
Zend_Validate_NotEmpty::IS_EMPTY => 'Value must be entered',
Zend_Validate_Regex::NOT_MATCH => 'Invalid value entered',
Zend_Validate_StringLength::TOO_SHORT => 'Value cannot be less than %min% characters',
Zend_Validate_StringLength::TOO_LONG => 'Value cannot be longer than %max% characters',
Zend_Validate_EmailAddress::INVALID => 'Invalid e-mail address'
);
$translator = new Zend_Translate('array', $translateValidators);
Zend_Validate_Abstract::setDefaultTranslator($translator);
Except when I drop it into the onBootstrap method in myZendApp/module/Application/Module.php, I get the following error message: ‘Application\Zend_Validate_NotEmpty’ not found in myZendApp/module/Application/Module.php on line 28
I can reference the classes directly, like so:
$translateValidators = array(
\\Zend\\Validator\\NotEmpty::IS_EMPTY => 'Value must be entered',
\\Zend\\Validator\\Regex::NOT_MATCH => 'Invalid value entered',
\\Zend\\Validator\\StringLength::TOO_SHORT => 'Value cannot be less than %min% characters',
\\Zend\\Validator\\StringLength::TOO_LONG => 'Value cannot be longer than %max% characters',
\\Zend\\Validator\\EmailAddress::INVALID => 'Invalid e-mail address'
);
which will get me the correct constants… However the closest thing to Zend_Translate I can find is Zend\Validator\Translator\TranslatorInterface:
/**

namespace Zend\\Validator\\Translator;
interface TranslatorInterface
{
/**
* @param string $message
* @param string $textDomain
* @param string $locale
* @return string
*/
public function translate($message, $textDomain = 'default', $locale = null);
}
OK, I’ve done a little more browsing through the API docs, and it looks like you may be able to do this:
$messages = array(
'Value must be entered' => \\Zend\\Validator\\NotEmpty::IS_EMPTY,
'Invalid value entered' => \\Zend\\Validator\\Regex::NOT_MATCH,
'Value cannot be less than %min% characters' => \\Zend\\Validator\\StringLength::TOO_SHORT,
'Value cannot be longer than %max% characters' => \\Zend\\Validator\\StringLength::TOO_LONG,
'Invalid e-mail address' => \\Zend\\Validator\\NotEmpty::IS_EMPTY
);
Zend\\Validator\\AbstractValidator::setMessages($messages);
which would be simpler.
Edit: I’ve altered the above example, as the keys and values have to be reversed.
I’ve added your code snippet to the onBootstrapper method, and I get the following error message: Fatal error: Call to undefined method Application\Module::setMessage() in /path/to/Zend/Validator/AbstractValidator.php on line 229
here’s the method in full:
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
$messages = array(
'Value must be entered' => Validator\\NotEmpty::IS_EMPTY,
'Invalid value entered' => Validator\\Regex::NOT_MATCH,
'Value cannot be less than %min% characters' => Validator\\StringLength::TOO_SHORT,
'Value cannot be longer than %max% characters' => Validator\\StringLength::TOO_LONG,
'Invalid e-mail address' => Validator\\NotEmpty::IS_EMPTY
);
Validator\\AbstractValidator::setMessages($messages);
}
I notice that Zend\Validator\AbstractValidator::setMessages() is trying to call a setMessage method in the above Module class.
I’m guessing setMessages() needs to be called from within a different class?
Yep, I get: Catchable fatal error: Argument 1 passed to Zend\Validator\AbstractValidator::setDefaultTranslator() must be an instance of Zend\Validator\Translator\TranslatorInterface, instance of Zend\I18n\Translator\Translator given
I tried changing the $translator to an instance of Zend\Validator\Translator\TranslatorInterface, but got the following error: Fatal error: Cannot instantiate interface Zend\Validator\Translator\TranslatorInterface
The __construct method needs to be passed a few variables:
<?php

*/
namespace Zend\\Validator\\Translator;
interface TranslatorInterface
{
/**
* @param string $message
* @param string $textDomain
* @param string $locale
* @return string
*/
public function translate($message, $textDomain = 'default', $locale = null);
}
OK, so I’ve downloaded the ZF getting started app, and I tried this:
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
$translator = $e->getApplication()->getServiceManager()->get('translator');
$translator->addTranslationFile(
'phpArray',
'vendor/zendframework/zendframework/resources/languages/en/Zend_Validate.php',
'default',
'en_US'
);
\\Zend\\Validator\\AbstractValidator::setDefaultTranslator($translator);
}
It doesn’t throw any errors, but I don’t know if it actually translates the messages or not either as I don’t have a form setup, but it looks like it might be worth a try.
