I had found the proplem, INVO uses stable 2.0.[http://stackoverflow.com/questions/35708732/phalcon-invo-project-register-process-fails]

I am new to Phalcon framework. After I finish filling the register form, and click submit, then I got a white page. There is not anything else error report.

My enviroment is Phalcon 2.1.0.RC1 - Windows x64 for PHP 5.5.0 (vc11) .

Here is th snippet of code:

public function indexAction() { $form = new RegisterForm;

    if ($this->request->isPost()) {
        //var_dump($this->request);exit;
        $name = $this->request->getPost('name', array('string', 'striptags'));
        $username = $this->request->getPost('username', 'alphanum');
        $email = $this->request->getPost('email', 'email');
        $password = $this->request->getPost('password');
        $repeatPassword = $this->request->getPost('repeatPassword');

        if ($password != $repeatPassword) {
            $this->flash->error('Passwords are different');
            return false;
        }
        $user = new Users();
        // it seems wrong from here
        $user->username = $username;
        $user->password = sha1($password);
        $user->name = $name;
        $user->email = $email;
        $user->created_at = new Phalcon\Db\RawValue('now()');
        $user->active = 'Y';
        // to here
        var_dump($user->save());exit;
        if ($user->save() == false) {
            foreach ($user->getMessages() as $message) {
                $this->flash->error((string) $message);
            }
        } else {
            $this->tag->setDefault('email', '');
            $this->tag->setDefault('password', '');
            $this->flash->success('Thanks for sign-up, please log-in to start generating invoices');
            return $this->forward('session/index');
        }
        //echo 8989898;
    }
    $this->view->form = $form;
}
