My providers is

'providers' => [

    /*
     * Laravel Framework Service Providers...
     */
    Illuminate\Auth\AuthServiceProvider::class,
    Illuminate\Broadcasting\BroadcastServiceProvider::class,

    Illuminate\Hashing\HashServiceProvider::class,
    Illuminate\Mail\MailServiceProvider::class,
    Illuminate\Notifications\NotificationServiceProvider::class,
    Illuminate\Pagination\PaginationServiceProvider::class,
    Illuminate\Pipeline\PipelineServiceProvider::class,
    Illuminate\Queue\QueueServiceProvider::class,

    App\Providers\AppServiceProvider::class,
    App\Providers\AuthServiceProvider::class,
    // App\Providers\BroadcastServiceProvider::class,
    App\Providers\EventServiceProvider::class,
    App\Providers\RouteServiceProvider::class,

],

I would like to write something like this in my Blade template:

     @foreach($services as $service)
            <div class="content" data-content="{{ Transliterate::slugify($service->tag) }}">
                <div class="list-previews-cases -closed">
                    <div class="cases">
                        @foreach($service->cases as $case)
                        <div class="case">
                            <img
                                src="{{ $case->preview_img }}"
                                class="img"
                                alt="">
                            <div class="title">{{ $case->title }}</div>
                            <div class="description">{{ $case->description }}</div>
                            <a href="/" class="link -blue">#{{ $service->tag }}</a>
                        </div>
                        @endforeach
                    </div>
                    @if($service->cases->count() > 1)
                    <span class="spoiler">More...</span>
                    @endif
                </div>
            </div>
            @endforeach

But as the result I see the following:

What is wrong? Can I use Facade in my Blade template?

Answer 1

According to MVC, you shouldn't use any complex logic in your view files. Consider moving it to your controller like this:

use ElForastero\Transliterate\Facade as Transliterate;

...
$slug = Transliterate::slugify($service->tag);
return view('your.view', ['slug' => $slug, ...]);

If you still want to access your facade in the view file, you can do this by specifing full path to it's class like so ElForastero\Transliterate\Facade::slugify(service->tag)

You can also wrap it into a helper function, if you expect to call this code multiple times in many places. Just create a new function in your Helpers/functions.php like so:

use ElForastero\Transliterate\Facade as Transliterate;

...
function slugify($tag) {
    return Transliterate::slugify($tag);
}

And then call it in your view like so: {{ slugify($service->tag) }}
