如何将参数从控制器传递到 YII2 中的布局

2022-01-07 00:00:00 php yii2

我想将参数从控制器发送到布局(即 main.php).但是我无法在 main.php 中获取参数

I want to send a parameter from controller to layout (i.e. main.php). But I am not able to get the param in main.php

我试过:

控制器代码:

$this->render('index',array('param' => $paramValue));

这就是我试图在布局中获得它的方式，即.main.php

And this is how i was trying to get this in layout ie. main.php

  1. $this->param(如 yii 1)
  2. $param
  1. $this->param (as in yii 1)
  2. $param

但是我无法在布局中获取参数值.谁能告诉我怎么做?

But i am not able to get param value in layout. Can anyone tell me how to do this?

推荐答案

yiiaseView 有特殊的 $params 属性.

例如，它用于使用 Gii 在默认生成的 CRUD 代码模板中构建面包屑.

For example it's used for building breadcrumbs in default generated CRUD code templates with Gii.

渲染前可以这样设置:

use Yii;

Yii::$app->view->params['customParam'] = 'customValue';

在控制器中，您可以这样设置:

Inside a controller you can set it like this:

$this->view->params['customParam'] = 'customValue';

然后它将在视图中可用(包括主布局):

Then it will be available in views (including main layout):

/* @var $this yiiwebView */

echo $this->params['customParam'];
