CakePHP 2.0中的表單助手出現錯誤

Question

我開始使用CakePHP 2.0，無法通過簡單的登錄。 這是我的代碼：

AppController的：

class AppController extends Controller
{
    function beforeFilter()
    {
        $this->Auth->userModel = 'User';
        $this->Auth->fields = array('username' => 'email', 'password' => 'password'); 
        $this->Auth->loginAction = array('controller' => 'users', 'action' => 'login');
        $this->Auth->loginRedirect = array('controller' => 'hotels', 'action' => 'dashboard');
    }
}

UsersController：

class UsersController extends AppController
{
    var $name = 'Users';
    var $helpers = array('Html','Form');
    var $components = array('Auth','Session');

    function beforeFilter()
    {
        $this->Auth->allow("logout");
        parent::beforeFilter();
    }

    function logout()
    {
        $this->redirect($this->Auth->logout());
    }

    function login()
    {
        if ($this->Auth->login())
        {
            $this->redirect($this->Auth->redirect());
        } else
        {
            $this->Session->setFlash(__('Invalid username or password, try again'));
        }
    }
}

login.ctp：

 echo $this->Form->create(); //'User', array('action' => 'login'));
 echo $form->Form->input('email');
 echo $form->Form->input('password');
 echo $form->Form->end('Login');

我得到的錯誤是這樣的：

 Notice (8): Undefined variable: form [APP\View\Users\login.ctp, line 13]
 Notice (8): Trying to get property of non-object [APP\View\Users\login.ctp, line 13]
 Fatal error: Call to a member function input() on a non-object in E:\proyectos\web\swt\app\View\Users\login.ctp on line 13

有任何想法嗎？ 提前致謝！

Answer 1

這些

echo $form->Form->input('email');
echo $form->Form->input('password');
echo $form->Form->end('Login');

應該

echo $this->Form->input('email');
echo $this->Form->input('password');
echo $this->Form->end('Login');
