Yii如何使用model来上传多个文件

我以前是使用CFormModel来上传图片（单张）。比如RegisterForm来注册用户上传照片并使用缩略图：

<code class="lang-php"><br><?php class RegisterForm extends CFormModel
{
    public $email;
    public $password;
    public $gender;
    public $homeland;
    public $iemi;
    public $registerDate;
    public $wentWhere;
    public $birthday;
    public $avatar; //头像，其最终结果应该是存储的Url
    public $thumb;//缩略图
    private $_identity;
    public function rules()
    {
        return array(

            array('email', 'required'),
            array('email','email','message'=>'email的格式不合法'),
            array('password', 'required'),
            array('gender','in','range'=>array(0,1)),
            array('homeland','required','message'=>'家乡必填，而且不容易更改'),
            array ('homeland','validateHome'),
            array('imei','required','message'=>'imei必填'),
            array('birthday','required','message'=>'birthday必填'),
            array('avatar','file','message'=>'必须设置一个头像')
        );
    }

    /**
     * Declares attribute labels.
     */
    public function attributeLabels()
    {
        return array(
            'email'=>'用户名/邮箱/手机号/漫游号',
            'password'=>'密码',
            'gender'=>'性别',
            ''
        );
    }

    /**
     * Authenticates the password.
     * This is the 'authenticate' validator as declared in rules().
     */
    public function authenticate($attribute,$params)
    {
        if(!$this->hasErrors())
        {
            $this->_identity=new UserIdentity($this->username,$this->password);
            if(!$this->_identity->authenticate())
                $this->addError('password','Incorrect username or password.');
        }
    }

    /**
     *     验证家乡是否合法。扩展到地级市
     *
     *
     */
    public   function validateHome(){

          $this->homeland;


          $this->addError('homeland','家乡不合法啊');



            }
    /**
     * Logs in the user using the given username and password in the model.
     * @return boolean whether login is successful
     */
    public function login()
    {
        if($this->_identity===null)
        {
            $this->_identity=new UserIdentity($this->username,$this->password);


            $this->_identity->setPersistentStates(array());
            $this->_identity->authenticate();
        }
        if($this->_identity->errorCode===UserIdentity::ERROR_NONE)
        {
            $duration=3600*24*10; // 10 days

            Yii::app()->user->login($this->_identity,$duration);
            return true;
        }
        else
            return false;
    }
}
</code>

然后在Controller里面：

<code class="lang-php">public function  actionRegister()
    {
        $registerForm = new RegisterForm();
        if (isset($_POST['RegisterForm'])) {
            $registerForm->attributes = $_POST['RegisterForm'];
            $registerForm->avatar = CUploadedFile::getInstance($registerForm, 'avatar');
            if ($registerForm->avatar) {
                $preRand = time() . mt_rand(0, 99999);
                $imageName='img_big'.$preRand.$registerForm->avatar->extensionName;
                $registerForm->avatar->saveAs('uploads/' . $imageName);
                $registerForm->avatar = $imageName;
            }
            $path = dirname(Yii::app()->BasePath) . '/uploads/';
            $thumb = Yii::app()->thumb; //与 $thumb=new Cthumb()有什么区别？
            $thumb->image = $path . 'img_small' . $preRand . $registerForm->avatar->extensionName;
            $thumb->width = 130;
            $thumb->height = 95;
            $thumb->mode = 4;
            $thumb->directory = $path;
            $thumb->defaultName = $preRand;
            $thumb->createThumb();
            $thumb->save();
            $registerForm->thumb = $thumb->image;
            $registerForm->registerDate = time();
//save方法会自动验证
            if ($registerForm->save() && $registerForm->login()) {
                Yii::app()->db->getLastInsertID(); //取得插入的Id。但是
            }

        }
</code>

上传的时候主要是这里：

<code class="lang-php">$registerForm->avatar = CUploadedFile::getInstance($registerForm, 'avatar');
</code>

但是现在遇到了一个问题。就是$registerForm继承了CFormModel，这个save方法是CActiveRecord的，为什么save方法就调用了呢？

此外，如果我要多文件上传，是不是

<code class="lang-php">$file1=CUploadedFile::getInstance($registerForm, 'file1');
$file2=CUploadedFile::getInstance($registerForm, 'file2');
</code>

就可以了？

你好啊。这个多文件上传的这问题你解决了吗？
