Zend Framework Custom Validation Class Error Message

问题

The validation fails as it should but does not return the error message.

       $form->addElement('text', 'phone_number', array(
     'required' => true,
       'validators' => array(
         array('NotEmpty', true, array('messages' => 'Enter a valid Phone Number')),
           array('regex', false, array('pattern' => '/\([0-9]{3}\)\s[0-9]{3}-[0-9]{4}/',
              'messages' => 'Enter a valid Phone Number'
     )),
           'CheckPhoneNumber'),

       ),
   ));

Custom Class:

class Custom_Validators_CheckPhoneNumber extends Zend_Validate_Abstract{
const IN_USE = 'inUse';

protected $_messageTemplates = array(
    self::IN_USE => "'%value%' is currently in use"
);

public function isValid($value)
{
    $this->_setValue($value);

        $user_check = Users::getActive(preg_replace("/[^0-9]/", "", $value));
        if($user_check->id){
            $this->_error(self::IN_USE);
            return false;
        }

  return true;
}

}

Just fails does not give the "IN_USE" error.

回答1:

Is it only the phone_number element which doesn't display errors or are there others?

Have you turned off default decorators with disableLoadDefaultDecorators?

How about this supplying the custom validator in an array:

$form->addElement(
    'text', 'phone_number', array(
        'required' => true,
        'validators' => array(
            array(
                'NotEmpty', true, array(
                    'messages' => 'Enter a valid Phone Number'
                )
            ),
            array(
                'regex', false, array(
                    'pattern' => '/\([0-9]{3}\)\s[0-9]{3}-[0-9]{4}/',
                    'messages' => 'Enter a valid Phone Number'
                )
            ),
            array(
                'CheckPhoneNumber'
            )
        )
    )
);

回答2:

Are you sure that it fails in your custom validator? Try to make sure that it actually fails in the custom validator.

If not, check if you have correct prefix path configured for elements of the form

$form->addElementPrefixPath(
  'Custom_Validators',
  'Custom/Validators',
  'validate'
);

The code for custom validator seems to be fine.

   $form->addElement('text', 'phone_number', array(
 'required' => true,
   'validators' => array(
     array('NotEmpty', true, array('messages' => 'Enter a valid Phone Number')),
       array('regex', false, array('pattern' => '/\([0-9]{3}\)\s[0-9]{3}-[0-9]{4}/',
          'messages'=>array(Zend_Validate_Regex::NOT_MATCH=>'%value% is not a valid phone')
 )),
       'CheckPhoneNumber'),

   ),
));
