YII,Model里面取Form提交的值

[艾派德迷你2]

我有一个登录页面,用的是LDAP...
Controller

public function actionLogin() {
        $model = new LoginForm;

        // if it is ajax validation request
        if (isset($_POST['ajax']) && $_POST['ajax'] === 'LoginForm') {
            echo CActiveForm::validate($model);
            Yii::app()->end();
        }

        if (isset($_POST['LoginForm'])) {
            $model->attributes = $_POST['LoginForm'];
            var_dump($model->attributes); //Question One
            if ($model->validate() && $model->login()) {
                $this->redirect(array('form/index'));
            }
        }
        $this->render('login', array('model' => $model));
    }

我的LoginForm Model里面,我要取userdomain的值,但是一直为空

class LoginForm extends CFormModel {

    public $username;
    public $password;
    public $userdomain;
    private $_identity;
    

    /**
     * Declares the validation rules.
     * The rules state that username and password are required,
     * and password needs to be authenticated.
     */
    public function rules() {
        return array(
            // username and password are required
            array('username', 'required', 'message' => 'Pls Key In Your NT Account.'),
            array('password', 'required', 'message' => 'Pls Key In Your NT Password.'),
            array('userdomain', 'required', 'message' => 'Pls Select Your Domain Host.'),
            // password needs to be authenticated
            array('password', 'authenticate'),
        );
    }

    /**
     * Declares attribute labels.
     */
    public function attributeLabels() {
        return array(
            'userdomain'=>'User Domain',
        );
    }

    /**
     * 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, $this->userdomain);
            if (!$this->_identity->authenticate())
                $this->addError('password', 'Incorrect username or password.');
        }
    }

    /**
     * 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->userdomain);
            $this->_identity->authenticate();
        }
        if ($this->_identity->errorCode === UserIdentity::ERROR_NONE) {
            return true;
        } else {
            return false;
        }
    }

}

但是我在Question One这里读取来是有值的
username' => string 'dasdasda' (length=8)
'password' => string 'asdasdasd' (length=9)
'userdomain' => string 'xxxxx' (length=5)

我再仔细查咯一下.. userdomain已经传给Model咯.. 但是我从Model里面传到Component / UserIdentity的没有userdomain/ 问题出在这里 CUserIdentity的构造函数 默认只有构造username,password... 所以不能传值给CUserIdentity. 必须在component / UserIdentity里面再定义一个方法.. 把userdomain给传递进去
