如何使用 Laravel 的 Blade 模板将变量传递给布局? [英] How do I pass a variable to the layout using Laravel' Blade templating?
问题描述
在 Laravel 4 中,我的控制器使用 Blade 布局:
class PagesController extends BaseController {受保护的 $layout = 'layouts.master';}
主布局已输出变量标题,然后显示一个视图:
<代码>...<title>{{ $title }}</title>...@yield('内容')……
但是,在我的控制器中,我似乎只能将变量传递给子视图,而不是布局.例如,一个动作可以是:
公共函数 index(){$this->layout->content = View::make('pages/index', array('title' => '主页'));}
这只会将 $title
变量传递给视图的内容部分.如何将该变量提供给整个视图,或者至少提供给主布局?
如果你在你的内容布局中使用 @extends
你可以使用这个:
@extends('master', ['title' => $title])
注意与上面相同的方法适用于孩子,例如:
<块引用>@include('views.subView', ['my_variable' => 'my-value'])
用法
然后将变量传递到哪里,像这样使用它:
<title>{{ $title ??'默认标题' }}</title>
In Laravel 4, my controller uses a Blade layout:
class PagesController extends BaseController {
protected $layout = 'layouts.master';
}
The master layout has outputs the variable title and then displays a view:
...
<title>{{ $title }}</title>
...
@yield('content')
....
However, in my controller I only appear to be able to pass variables to the subview, not the layout. For example, an action could be:
public function index()
{
$this->layout->content = View::make('pages/index', array('title' => 'Home page'));
}
This will only pass the $title
variable to the content section of the view. How can I provide that variable to the whole view, or at the very least the master layout?
If you're using @extends
in your content layout you can use this:
@extends('master', ['title' => $title])
Note that same as above works with childs, like:
@include('views.subView', ['my_variable' => 'my-value'])
Usage
Then where variable is passed to, use it like:
<title>{{ $title ?? 'Default Title' }}</title>
