使用setAction时，Zend表单验证失败

Basically isValid is the method to validate a form:

$form = new Application_Form_easy();
$formData = $this->_request->getPost();
if($form->isValid($formData)){
 //Form is valid, do your stuff
} else {
 //Form is not valid re-populate data
 $form->populate($formData);
}

In your case you are setting the form action this one /index.php/releases/connectTracking and you have written your validation code in easyAction which is wrong. you have two ways here to achieve your requirement;

1) Set action of your form this /controllerName/easy and validate your form in easyAction (which you are doing right now) and if form is valid then redirect control to releases/connectTracking action.

2) Another way is to write your validation code in releases/connectTracking Action and if form is not valid then redirect control again to easy Action with all the POST data to re-populate the form. And if form is valid then continue your stuff at releases/connectTracking action.

E.g. for first solution:

Controller:

public function easyAction(){
    $auth = Zend_Auth::getInstance();
    $user_id = $this->_helper->Utilities->getCurrentUserId();

    if ($auth->hasIdentity()) {
        $form       = new Application_Form_easy();
        $form->submit->setLabel('Submit');
        $this->view->form = $form;  
        $formData = $this->getRequest()->getPost();

        if ($form->isValid($formData)) { 
            $username = $form->getValue('username');                
            $password = $form->getValue('password');
            $releasedata = array('username' => $username, 'password' => $password);
            //Form is valid, hence forward controller to another action with formData
            $this->_request->setPost(array('formData' => $formData));
            //Write actual module name in the below line
            $this->_forward('connectTracking', 'releases', 'moduleName');
            //$this->_redirect('/releases/connectTracking');
        } else {
          $form->populate($formData);
        }
    }
}

Form:

class Application_Form_easy extends Zend_Form {
    public function init() {
        $this->setMethod('post');
        $this->setName('easyform');
        //Write actual name of your controller here
        $this->setAction('/controllerName/easy'); # Submitting to same action

        $username = new Zend_Form_Element_Text('username');
        $username->setLabel('Username * :')
                ->setRequired(true)
                ->addValidator('NotEmpty', true, array('messages' => 'Please enter Username'));

        $password = new Zend_Form_Element_Password('password');
        $password->setLabel('Password * :')
                ->setRequired(true)
                ->addValidator('NotEmpty', true, array('messages' => 'Please enter password '));

                $submit = new Zend_Form_Element_Submit('submit');
                $submit->setAttrib('id', 'easyform');
                $submit->setAttrib('name', 'easyform');
                $this->addElements(array($username, $password, $submit));
    }
}
