php - Laravel 5 具有多个变量的 View 编辑器

Question

有没有更优雅的做法:

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 View 编辑器:

导航 Composer

 namespace App\Http\ViewComposers;

use Illuminate\Contracts\View\View;
use Illuminate\Support\Facades\Auth;

class NavigationComposer
{
    protected $user;

    public function __construct()
    {
        $this->user = Auth::user();
    }

    public function compose(View $view)
    {
        $view->with(['nav' => $this->topNav(), 'sidebar' => $this->sidebar()]);
    }

    public function topNav()
    {
        $nav['Dashboard'] = [
            'route' => 'dashboard'
        ];
        $nav['Sales'] = [
            'route' => 'sales',
            'subitems' => [
                'Enquiries' => 'sales.enquiries',
                'Quotes' => 'sales.quotes',
                'Orders' => 'sales.orders'
            ]
        ];
        $nav['CRM'] = [
            'route' => 'crm',
            'subitems' => [
                'Companies' => 'crm.companies',
                'Conversion report' => 'crm.conversion-report'
            ]
        ];
        return $nav;
    }

    public function sidebar()
    {
        return 'sidebar';
    }
}

ComposerServiceProvider

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class ComposerServiceProvider extends ServiceProvider
{
    /**
     * Register bindings in the container.
     *
     * @return void
     */
    public function boot()
    {
        // Using class based composers...
        view()->composer(
            'includes.topbar', 'App\Http\ViewComposers\NavigationComposer'
        );
        view()->composer(
            'includes.sidebar', 'App\Http\ViewComposers\NavigationComposer'
        );
    }
    ...
}

我按照@Gal 的建议将它们分成两部分

ComposerServiceProvider

...
public function boot()
    {
        // Using class based composers...
        view()->composer('includes.topbar', 'App\Http\ViewComposers\TopNavigationComposer');
        view()->composer('includes.sidebar', 'App\Http\ViewComposers\SidebarComposer');
    }
...

TopNavigationComposer

...
public function compose(View $view)
    {
        $view->with('nav', $this->topNav());
    }

    public function topNav()
    {
        $nav['Dashboard'] = [
            'route' => 'dashboard'
        ];
        $nav['Sales'] = [
            'route' => 'sales',
            'subitems' => [
                'Enquiries' => 'sales.enquiries',
                'Quotes' => 'sales.quotes',
                'Orders' => 'sales.orders'
            ]
        ];
        $nav['CRM'] = [
            'route' => 'crm',
            'subitems' => [
                'Companies' => 'crm.companies',
                'Conversion report' => 'crm.conversion-report'
            ]
        ];
        return $nav;
    }
...

侧边栏 Composer

...
public function compose(View $view)
    {
        $view->with('sidebar', $this->sidebar());
    }

    public function sidebar()
    {
        return 'sidebar';
    }
...

您可以在 View 编辑器函数中使用多个 with 链来检索变量。

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