如何将变量传递给布局? [英] How to pass variables to layout?

问题描述

我知道如何将变量从控制器传递到视图中

I know how to pass variable from controller into a view:

$this->render('view_name', array('variable_name'=>'variable_value'));

但是我想将一些变量传递给布局.控制器和布局之间的唯一连接似乎是控制器类中的public $ layout属性，如下所示:

however I'd like to pass some variables to layout. The only connection between controller and layout seems to be the public $layout attribute in controller class, like this:

public $layout='//layouts/column2';

但是，我看不到将变量传递给它的方法吗?

However, I do not see a way to pass a variable to it?

推荐答案

在您的控制器中，您可以执行以下操作:

From your controller you can do something like this:

$this->render('/mail/registration',array('url'=>$url, 'description'=>'some description'));

，然后从您的视图访问变量，如下所示:

and access the variables from your view like this:

<h3><?php echo $url; ?></h3>

这是您的答案；您可以像这样从布局访问这些相同的变量:

and here is your answer; you can access these same variables from the layout like this:

<h3><?php echo $data['url']; ?></h3>
