Php 具有多个变量的Laravel 5视图生成器

php laravel laravel-5

Php 具有多个变量的Laravel 5视图生成器,php,laravel,laravel-5,Php,Laravel,Laravel 5,有没有更优雅的方式： abstract class Controller extends BaseController { use DispatchesJobs, ValidatesRequests; function __construct() { view()->composer('includes.topbar', function ($view) { $view->with('nav', $this->topNa

有没有更优雅的方式：

abstract class Controller extends BaseController
{
    use DispatchesJobs, ValidatesRequests;

    function __construct() {
        view()->composer('includes.topbar', function ($view) {
            $view->with('nav', $this->topNav());
        });
        view()->composer('includes.sidebar', function ($view) {
            $view->with('sidebar', $this->sidebar());
        });
    }
    ...
}

使用视图生成器：

如果只想在主布局中访问局部视图，可以执行以下操作

在主布局中，为局部视图创建剖面：

@section('partial_view_1')
@show
@section('partial_view_2')
@show

在控制器的构造函数中，执行此操作时，请确保声明

$layout

$this -> layout  = view('layouts.master');
$this -> layout -> partial_view_1 = view('includes.top_nav'); 
// -> with($data); if you want to pass data to the top nav. 
$this -> layout -> partial_view_2 = view('includes.side_nav');

public function index(){
    $this -> layout -> main_content = view('contents.main');
    return $this -> layout;
 }

现在，如果希望在调用视图时将数据绑定到视图，则可能需要使用

视图生成器

。希望这有帮助

试试这个。这是我的工作。

您可以在view composer函数中使用multiple with chain来检索变量

//For all views
\View::composer('*', function($views){
           $views->with('users', App\User::all())
           ->with('roles', App\Role::all())
           ->with('publishers', Publisher::all());
        });

有关更多信息：

您所做的一切都没有问题。您正在将不同的变量绑定到不同的视图。我不会将view composer放在一个控制器中，而是创建一个服务提供程序，以便在您似乎将所有“全局”内容都放在主控制器中的那一刻使其更有条理。@Gal我已经这样做了，它正在工作，但我不确定boot（）服务提供者中的节。我真的需要将同一个东西绑定到两个视图上两次吗？@imperium2335我不这么认为，这就是为什么我还要将

NavigationComposer

文件一分为二，一个用于topbar，一个用于侧栏，正如您发送到

topbar

查看

sidebar

变量和

sidebar

查看

nav

变量时一样。我不知道您的函数做了什么，但您可能会做一些事情两次。@Gal我有一些函数根据用户角色在其中生成导航，有关NavigationComposer的完整版本，请参见我的编辑
