include(password.php）[lt；a href='；function.include'；&g

我是yii框架的新手，刚刚4天我就陷入了这个问题，下面是我的代码。。

这是视图。。。

<div class="form">
<?php echo CHtml::beginForm(); ?>
<?php echo CHtml::errorSummary($model); ?>
<div class="row">
    <?php echo CHtml::activeLabel($model,'email'); ?>
    <?php echo CHtml::activeEmailField($model , 'email') ?>
</div>  
<div class="row">
<?php  echo CHtml::activeLabel($model, 'password'); ?>
<?php  echo  CHtml::activePasswordField($model, 'password');  ?>
</div>
 <?php echo CHtml::endForm(); ?>    

我的模型的简单代码

<?php
class C_regsiter extends CFormModel{
public $username;
public $Password;
public $email;
public $data; 
protected  $id;
public function rules(){
return array(
array('username','password','email','required'),
array('email','email'),      
);
 }
public function attributelabel(){

 return array(
 'username'=>'User Name',
 'Password'=>'Password',
 'email'=>'Email Address '
); 
}
}

这是我的控制器

class RegisterController extends Controller
{
 public function actionIndex()
 {
  $model=new C_regsiter();
  $this->render('index',array('model'=>$model));
 }

问题是无论何时调用activepasswordfield都会出错帮助
