如何在没有模块的情况下动态设置错误处理程序的布局 [英] How to set layout for errorhandler dynamically without module

问题描述

我是 Yii2 的新手，

I am new in Yii2,

当我开始创建一个网站时，我发现你可以像这样在配置中设置ErrorAction

When I started creating a website, i found that you can set ErrorAction in configuration like this

 'errorHandler' => [
            'errorAction' => 'site/error',

        ],

使用 layout/main.php 中的布局时出现的错误.当访客访问位于视图/站点"中的页面时使用该布局.但是当用户登录视图页面时，位于不同文件夹中的view/band"布局变得完全不同，并且使用layout/BandLayout".我知道你可以像在 BandController 中一样在控制器中动态更改布局

That error using layout from layout/main.php. That layout was used when guest visit the page that located in 'view/site'. But when the user log in the view page locate in different folder which is 'view/band' the layout become totally different and using 'layout/BandLayout'. I know that you can change layout dynamically in controller like i did in BandController

public $layout ='BandLayout';

这将改变view/band"中的整个布局.但是当出现像404"这样的错误时，布局仍然使用 layout/main.php 中的布局.我已经做了一些搜索，但在模块中使用 init() 的解决方案.由于我还没有学习模块，如何在控制器中为错误布局设置布局?

That will change the entire layout in 'view/band'. But when there is an error like '404' the layout still using layout from layout/main.php. I have done some searching but the solution using init() in module. Since i have not learn module, how do I set layout for error layout in controller?

谢谢

推荐答案

您应该在 SiteController 中更改布局，您可以使用 beforeAction，例如:

You should change layout in SiteController, you could use beforeAction, e.g. :

public function beforeAction($action)
{
    if (parent::beforeAction($action)) {
        // change layout for error action
        if ($action->id=='error')
             $this->layout ='BandLayout';
        return true;
    } else {
        return false;
    }
}
