登录模块错误:属性“LoginForm._id"没有定义 [英] Login Module Error: Property "LoginForm._id" is not defined

问题描述

我正在尝试在 Yii 中创建登录模块，但出现意外错误:

I am trying to create a login module in Yii but I am getting an unexpected error:

未定义属性LoginForm._id".

Property "LoginForm._id" is not defined.

我在 UserIdentify 类上使用 $_id 变量.为什么会显示 LoginForm._id not defined 的错误?

I am using an $_id variable on UserIdentify class. Why it is showing an error that LoginForm._id not defined?

class UserIdentity extends CUserIdentity {

    /**
     * Authenticates a user.
     */
    private $_id;

    public function authenticate() {
        $user = Users::model()->findByAttributes(array('username' => $this->username));
        if ($user === null)
            $this->errorCode = self::ERROR_USERNAME_INVALID;
        else if ($user->password !== $this->password)
            $this->errorCode = self::ERROR_PASSWORD_INVALID;
        else {
            $this->_id = $user->id;
            $this->setState('lastLoginTime', $user->lastLoginTime);
            $this->errorCode = self::ERROR_NONE;
        }
        return !$this->errorCode;
    }

    public function getId() {
        return $this->id;
    }

}

推荐答案

你应该修正错字:

    /**
     * @return integer the ID of the user record
     */
    public function getId()
    {
        return $this->_id;
    }
