Yii2 - 检查用户是否登录视图 [英] Yii2 - check if the user is logged in view

问题描述

我正在尝试检查用户是否登录到我的视图文件中，但我不断收到此错误:

I am trying to check is the user logged inside my view file, but I keep getting this error:

Call to undefined method Yii::app()

我尝试在 app 之前添加 $ 但错误仍然存​​在(这次是 未定义变量:app).这是视图可能吗?

I tried adding $ before app but the error is still there (this time it is Undefined variable: app). Is it possible to this is view?

这是我用来检查用户是否登录的代码:

This is the code I use the check if the user is logged:

<?php
        if(Yii::app()->isGuest)
            echo 'User is not logged!';
    ?>

推荐答案

在 Yii2 中正确的语法是

In Yii2 the correct syntax is

Yii::$app->user->getIsGuest();

或

Yii::$app->user->isGuest;
