How do I return a custom 'isEmpty' error message from Zend\Validator\Identical in Zend Framework 2?

Question

zendframework 2 inputfilter customize default error message

I'm trying to use Zend\InputFilter\InputFilter to validate the input from a registration form. I have the code below that:

Validates the email address in the 'email' field; then
Checks the value in 'email_confirm' matches the one in 'email'.

This works in in all instances other than when the user leaves both fields blank. In that instance the validator for 'email_confirm' returns the error Array ( [isEmpty] => Value is required and can't be empty ).

How do I customise this error message? I cannot set it using:

'messages' => array(
    'isEmpty' => 'Message Here' 
),

because that throws an exception saying (quite rightly) that Zend\Validator\Identical does not have a message template for 'isEmpty'. And it's not picking up the messages I've previously set for the 'email' field, otherwise it would be returning Array ( [isEmpty] => Please enter your email address ).

$this->add($inputFactory->createInput(array(
    'name' => 'email',
    'required' => true,
    'filters' => array(
        array('name' => 'StripTags'),
        array('name' => 'StringTrim'),
    ),
    'validators' => array(
        array(
          'name' =>'NotEmpty', 
            'options' => array(
                'messages' => array(
                    'isEmpty' => 'Please enter your email address' 
                ),
            ),
        ),
        array(
            'name' => 'StringLength',
            'options' => array(
                'encoding' => 'UTF-8',
                'max' => 200,
                'messages' => array(
                    'stringLengthTooLong' => "Email addresses cannot be more than 200 characters"
                ),
            ),
        ),
        array(
          'name' =>'EmailAddress', 
            'options' => array(
                'useMxCheck'    => true,
            ),
        ),                
    ),
))); 

$this->add($inputFactory->createInput(array(
    'name' => 'email_confirm',
    'required' => true,
    'filters' => array(
        array('name' => 'StripTags'),
        array('name' => 'StringTrim'),
    ),
    'validators' => array(
        array(
            'name' => 'Identical',                        
            'options' => array(
                'token' => 'email',
                'messages' => array(
                     'notSame' => "Your email addresses do not match, please try again",
                ),
            ),
        ),               
    ),
)));

You have to use Zend\Validator\NotEmpty::IS_EMPTY constant this way:

array(
    'name' =>'NotEmpty', 
        'options' => array(
            'messages' => array(
                \Zend\Validator\NotEmpty::IS_EMPTY => 'Please enter your email address' 
        ),
    ),
),

You can check out the API for further info.

EDIT

Diving into Zend\Validator\NotEmpty source code I see that IS_EMPTY constant has 'isEmpty' value, so it won't fix your problem. Anyway, you should use these constants instead of direct values in order to avoid possible updating issues.

I'm afraid that doesn't work. \Zend\Validator\NotEmpty::IS_EMPTY simply returns the constant 'isEmpty', thus it's the exact same issue as if I was calling `'messages' => array('isEmpty' => 'Message Here')`. – Neil Nov 12 '12 at 12:46
@Neil you are right, see my edit on that. I'm trying to find another way to solve your problem. Do the other validators show their custom messages properly? – Carlos Nov 12 '12 at 12:49
Yes, all the other validators' custom messages work fine. – Neil Nov 12 '12 at 12:51
What's the exact message currently returned by `NotEmpty` when `isEmpty` email address? `"Value is required and can't be empty"`? – Carlos Nov 12 '12 at 14:33
My _NotEmpty_ validator on the 'email' field returns `Array ( [isEmpty] => Please enter your email address )`, as per my custom message. My _Identical_ validator returns `Array ( [isEmpty] => Value is required and can't be empty )`. – Neil Nov 12 '12 at 15:44
