Question

I am a newbie in zf, recently I m making a register form using zend_dojo_form and there are two passwordtextbox elements, which u know, one is for entering password and the other is to confirm the former one, then I using the validator ‘token’ but failed, here is part of my code.

$this->addElement('PasswordTextBox','password',array(
            'label'=>'password:',
            'required'=>true,
            'trim'=>true,
            'regExp'=>'^[a-z0-9]{6,18}$',
            'invalidMessage'=>'password should be 6-18',
            'Decorators' => array(
                'DijitElement',
                'Errors',
                array(array('data'=>'HtmlTag'),array('tag'=>'td','align'=>'left')),
                array('Label',array('tag'=>'td')),
                array(array('row'=>'HtmlTag'),array('tag'=>'tr','align'=>'right'))
                )
            )
        );
    //$this->addElement($password1);

    $this->addElement('PasswordTextBox','password2',array(
        'label'=>'confirm password:',
        'required'=>true,
        'trim'=>true,
        //'regExp'=>'^[a-z0-9]{6,18}$',
        'validators'=>array(array('identical',false,array('token'=>'password'))),
        'invalidMessage'=>'the password you enter not the same',
        'Decorators' => array(
            'DijitElement',
            'Errors',
            array(array('data'=>'HtmlTag'),array('tag'=>'td','align'=>'left')),
            array('Label',array('tag'=>'td')),
            array(array('row'=>'HtmlTag'),array('tag'=>'tr','align'=>'right'))
            )
        )
    );

Here’s a sample that should be functional:

class Application_Form_Register extends Zend_Dojo_Form {

    public function init() {
            $this
                            ->setOptions(array('name' => 'registerForm'))
                            // username
                            ->addElement('TextBox', 'first_name', array(
                                    'filters' => array('StringTrim', 'StringToLower'),
                                    'id' => 'name_register',
                                    'required' => true,
                                    'label' => 'Fornavn(e):',
                            ))
                            ->addElement('TextBox', 'last_name', array(
                                    'filters' => array('StringTrim', 'StringToLower'),
                                    'id' => 'surname_register',
                                    'label' => 'Efternavn:',
                            ))
                            ->addElement('ValidationTextBox', 'email', array(
                                    'filters' => array('StringTrim', 'StringToLower'),

                                    ),

                            ))
                           ->addElement('PasswordTextBox', 'password_confirm', array(
                                    'filters' => array('StringTrim'),

                           ->addElement('PasswordTextBox', 'password_confirm', array(
                                    'filters' => array('StringTrim'),
                                    'validators' => array(
                                            'Alnum',

                                    'label' => 'Gentag password:',
                            ))
                            ->addElement('Hidden', 'action', array(

    }
    // renders nulled empty labels and adds classnames, related to element name
    protected function _decorate() {
            $this->setDecorators(array(
                    'FormElements',
                    array('HtmlTag', array('tag' => 'div', 'class' => 'zend_form_contents')),
                    'DijitForm'
            ));

            foreach ($this->getElements() as $el) {

                    $el->addDecorator('HtmlTag', array('tag' => 'div', 'class' => $el->getName() . '-wrap'));
                    if ($el->helper == 'Button')
                            continue;
                    else if (strlen(trim($el->getLabel())) == 0)
                            $el->addDecorator('Label', array('tag' => null));
                    else
                            $el->addDecorator('Label', array('tag' => 'div', 'class' => $el->getName() . '-label'));
            }
    }
}

Focusing on the two password fields – in terms of what makes clientside validation tick, lets filter out the Zend_Form_Element attributes:

 ->addElement('PasswordTextBox', 'password_2_', array(
       // strictly serverside, only accepts alphanumerical pwds lengths 6 through 20
       'validators' => array(
           'Alnum',
           array('StringLength', false, array(6, 20)),
       ),
       // widget id
       'id' => 'passwordconfirm_register1',
       // both client-/server-side - triggers 'emptyMessage' validation
       'required' => true,
       // runs with the form.validate() and events onblur, oninit, onkeypress
       // if ! dijit.get("value").match(dijit.regExp) show 'invalidMessage'
       // this example matches the serverside reqs
       'regExp' => "^([a-zA-Z0-9_\-!-=]){6,32}$",
       // shown with form.validate(), dijit.validate() and input.blur() if regExp is not  a match against value
       'invalidMessage' => 'Password musts: 6 to 32 chars and only numbers, letters or amongst [ _-!"#%&/()=]',
  ))

And a second pwd field, same attributes but with a different validator

 ->addElement('PasswordTextBox', 'password_2_', array(
       // strictly serverside, only accepts alphanumerical pwds lengths 6 through 20
       'validators' => array(
           array('identical',false,array('token'=>'password'))
       ),
       // widget id
       'id' => 'passwordconfirm_register2',
       'required' => true,
       // in theory, we would define 'validator' in programmatic construct of
       // the validationtextbox. but this will not work with the way Zend handles dojo
       // 'validator' => 'function(value, constraints) { return "BAD PRACTICE" }'
  ));
  // add javascript code to run onload and to extend the 'register2' properly
  $this->getElement()
      ->getView()
      ->headScript()
      ->appendFile($baseUrl . '/js/Validator.js');

By now, only ‘required’ is validated clientside in the passwordconfirm_register2 widget. Lets fix in what markup factory does in regards to ‘bad practice’ in the above lines. Remove that line and add the javascript code instead, containing:

// file: baseUrl/js/Validator.js
dojo.addOnLoad(function() {
  dijit.byId('passwordconfirm_register2').validate = function(value, constraints) {

     if(dijit.byId('passwordconfirm_register1').get("value") != value) {
            this.invalidMessage = "Passwords are not identical";
            return false;
     }

     return true

  });
});
