Early View Data Preparation with Laravel View Creators

Laravel view creator allows you to prepare data immediately after view instantiation, earlier than view combinator, which makes them ideal for setting up necessary view data or optimizing performance.

Let's look at a practical example of managing dynamic application menus:

First, register the view creator:

use Illuminate\Support\Facades\View;
// 注册视图创建器
View::creator('dashboard', DashboardCreator::class);

Next, define the view creator class:

<?php namespace App\View\Creators;

use App\Services\MenuService;
use Illuminate\View\View;
use Illuminate\Support\Facades\Auth;

class ApplicationMenuCreator
{
    protected $menuService;

    public function __construct(MenuService $menuService)
    {
        $this->menuService = $menuService;
    }

    public function create(View $view)
    {
        $user = Auth::user();

        $view->with([
            'mainMenu' => $this->menuService->getMainMenu($user),
            'quickActions' => $this->menuService->getQuickActions($user),
            'recentItems' => $this->menuService->getRecentItems($user),
            'notifications' => $this->menuService->getPendingNotifications($user)
        ]);
    }
}

Register view creator in your AppServiceProvider:

// 在你的 AppServiceProvider
public function boot()
{
    View::creator('layouts.app', ApplicationMenuCreator::class);
}

Lastly, use data in layouts/app.blade.php:

<div class="sidebar">
    <nav>
        @foreach($mainMenu as $menuItem)
            <a class="https://www.php.cn/link/a754fc1765a45a6bc1a034140afd0669'active'] ? 'active' : '' }}" href="https://www.php.cn/link/a754fc1765a45a6bc1a034140afd0669'url'%5D%20%7D%7D">
                https://www.php.cn/link/a754fc1765a45a6bc1a034140afd0669'label'] }}
            </a>
        @endforeach
    </nav>

    @if(count($quickActions))
        <div class="quick-actions">
            @foreach($quickActions as $action)

                    {{ $action['label'] }}

            @endforeach
        </div>
    @endif
</div>
