[fw-general] Re: Zend_Filter_Input and overriding default error message

[Joshua Ross]

Yes, I didn't quite grasp that in the documentation.  That is working, thanks!

  You have to setup the error messages as an array with all of the possible 
error values.  Using your example:


$validators = array('fname' => array('Alpha',
                    'presence' => 'required',
                    'messages' => array(
                        Zend_Validate_Alpha::NOT_ALPHA => 'Custom not alpha 
error message.',
                        Zend_Validate_Alpha::STRING_EMPTY => 'Custom empty 
string error message.'
));
Hope that helps.

I have a question about Zend_Filter_Input.  I have read and reread the 
documentation and I am confused about the what can be done with the messages 
parameter when defining a validator.  The problem is that if I have a value 
string that is empty it seems I cannot override the error message that is 
returned.  Maybe I am just not understanding the documentation fully?  Here 
is the code(generecized):

$validators = array('fname' => array('Alpha',
                                  'presence' => 'required',
                                  'messages' => 'Invalid First Name'));
$filters = array();
$options = array('missingMessage' => 'test message 2',
                          'notEmptyMessage' => 'test message 3');
$input = Zend_Filter_Input($filters, $validators, 
$this->getRequest()->getPost(), $options);

if ($input->hasMissing() || $input->hasInvalid()) {
    $msg ='';
    foreach($input->getMessages() as $error) {
        $msg .= implode("\n", $error);
    }
    throw new My_Exception($msg);
}

I expect to receive one of my three test messages for any error from this 
validator and I have tried both $input->getMessages() and 
$input->getErrors()...  however when the string is empty I always receive 
the following message.

'' is an empty string


When I dump the $input after it processes I see:
...

Any help here understanding my mistake or what I'm doing wrong would be 
appreciated.  Thanks
