请记住我在yii中无法在我的浏览器上运行的功能

Question

您好我通过数据库用户名和密码登录我的应用程序，我也想检查记住我复选框，但它没有设置我的用户名和密码。

'user' => array(
            // enable cookie-based authentication
            'allowAutoLogin'=>true,

),

main.php。

中的组件代码

    public function login()
    {            
            if($this->_identity===null)
            {
                    $this->_identity=new UserIdentity($this->username,$this->password);
                    $this->_identity->authenticate();
            }
            if($this->_identity->errorCode===UserIdentity::ERROR_NONE)
            {
                    $duration=$this->rememberMe ? 3600*24*30 : 0; // 30 days
                    Yii::app()->user->login($this->_identity,$duration);
                    return true;
            }
            else
                    return false;
    }


    public function authenticate()
    {
        // Create an instance from model Employee and search
        $employee = Employee::model()->findByAttributes(array('email'=>$this->username));

        //Swap original if(!isset($users[$this->username]))
        if(!isset($employee->username))
            $this->errorCode=self::ERROR_USERNAME_INVALID;
        //Swap original elseif($users[$this->password]!==$this->password)
        elseif($employee->password!=$this->password)
            $this->errorCode=self::ERROR_PASSWORD_INVALID;
        else
            $this->errorCode=self::ERROR_NONE;
        return !$this->errorCode;
    }

帮助将不胜感激。
