Zend_Dojo_Form passwordTextBox validator don't work - zend-framework

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'),
'validators' => array(
'EmailAddress',
array('StringLength', false, array(3, 60)),
),
'regExp' => "^(([^<>()[\]\\.,;:\s#\"]+(\.[^<>()[\]\\.,;:\s#\"]+)*)|(\".+\"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$",
'id' => 'email_register',
'required' => true,
'label' => 'E-mail:',
))
//password
->addElement('PasswordTextBox', 'password', array(
'filters' => array('StringTrim'),
'validators' => array(
'Alnum',
array('StringLength', false, array(6, 20)),
),
'regExp' => "^([a-zA-Z0-9_\-!-=]){4,32}$",
'tooltipPosition' => 'above',
'invalidMessage' => 'Krav til password: mellem 4 og 32 i længde og kun karakterer som tal, bogstaver eller blandt [ _-!"#%&/()=] er tilladt',
'id' => 'password_register',
'onKeyDown' => 'arguments[0].keyCode == dojo.keys.ENTER && application.submitRegistration(dijit.byId(\'registerForm\'));',
'required' => true,
'label' => 'Password:',
))
->addElement('PasswordTextBox', 'password_confirm', array(
'filters' => array('StringTrim'),
'validators' => array(
'Alnum',
array('StringLength', false, array(6, 20)),
),
'id' => 'passwordconfirm_register1',
'onKeyDown' => 'arguments[0].keyCode == dojo.keys.ENTER && application.submitRegistration(dijit.byId(\'registerForm\'));',
'required' => true,
'label' => 'Gentag password:',
))
->addElement('PasswordTextBox', 'password_confirm', array(
'filters' => array('StringTrim'),
'validators' => array(
'Alnum',
array('StringLength', false, array(6, 20)),
),
'id' => 'passwordconfirm_register2',
'onKeyDown' => 'arguments[0].keyCode == dojo.keys.ENTER && application.submitRegistration(dijit.byId(\'registerForm\'));',
'required' => true,
'label' => 'Gentag password:',
))
->addElement('Hidden', 'action', array(
'id' => 'action_register',
'value' => 'register',
))
->addElement('Button', 'foo', array(
'id' => 'foo_register',
'onClick' => 'application.submitRegistration(dijit.byId(\'registerForm\'))',
'label' => 'Register'
)
);
$this->_decorate();
}
// 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
});
});
