Zend_Validate_Identical not working.

kmg · #1 (**permalink**) 03-14-2008, 02:32 AM

I can't get Zend_Validate_Identical to work. It just always says "No token was provided to match against", no matter what.

PHP Code:


			


        $form->addElement('text', 'first', 

            array(

                'required'    => true,

                'label'        => 'First Name',

                'validators'    => array(

                    'alnum',

                    array('StringLength', 50, 3),

                    array('regex', false, '/^[a-zA-Z]/i'),

                    array('Identical', 'test')

                    ),

                )

            );

So what's the deal?

Also, I need to compare one form field to another form field (password to confirm password), and the easiest way I could think while following the validation model was to write a custom validator, something like Zend_Validate_IdenticalToField that would just take in a form element, and call it's getValue method for comparison. Is there some better way this could be implemented within the Zend_Form / Zend_Validate pattern? Also, what about a UniqueInModelField validator that checks against a model for any existing entries that would conflict, like for a unique email address? These are probably outside of the scope of Zend_Validate by quite a bit though. What do you guys think?

you should use this:
array('Identical', $variable)

if you set 'test', the validator compares text from your input field with the 'test' word

if you have input field named 'test', you should write something like that:

array('Identical', $this->getRequest()->getParam('test'))

in other words:

Code:

//password entered in the form
$password = $this->getRequest()->getParam('password'); 

//repeat password field in your form
$form->addElement('password', 'repeat_password', 
        array(
                //...
                'validators'    => array(
                 //...
                    array('Identical', $password)

Hi,

I am currently having the same problem and the solution you are provided doesnt work. Any clue ?

I get the "No token was provided to match against".

Thanks for your help.

I solved it this way.

NOTE: - $context['wachtwoordA] is the name of the first passwordfield
- $value is the value of the field which it is validating.
- This is the isValid method from my own custom validator

Code:

    public function isValid($value, $context = null)
    {
        $value = (string) $value;
        $this->_setValue($value);

      	  if (is_array($context))
      	   {
      	      if (isset($context['wachtwoordA'])
     	           && ($value == $context['wachtwoordA']))
     	       {
    	            return true;
    	       }
      	   }
          elseif (is_string($context) && ($value == $context))
           {
            return true;
           }
         
        $this->_error(self::NOT_MATCH);
        return false;
    }

Greetings All,

I have created a more generic solution to this problem, allowing one to validate any field against any other field (e.g. make sure passwords match, emails match, value match captcha challenge, etc.). I couldn't seem to get the markup on this page to look right, so I've provided the code at the this link along with example usage. Enjoy!

Hi,

I ran into the same problems. I tried to fix it like this

PHP Code:


			
$password2        = new Zend_Form_Element_Password('password2');

$password2->setLabel('Repeat password')

            ->setRequired(true)

            ->addValidator(new Zend_Validate_Identical($_POST['password']));

This seems to work just fine, at least for me.
