Putting data into master blade - Laravel

I have seen a few similar questions to mine, with the common answer being to use a view composer. I have a HomeController that shows articles from a database by passing query data to an associated view, which works see this image link

As you can see there is a nav bar, which is generated by the master layout, layout.master.

For each title in the navigation I am trying to show each article for that section via a for loop which generates the links.

My code is this.

public function index()
{
    $loans_articles = Article::byDepartment('Loans')->get();
    $digital_articles = Article::byDepartment('Digital')->get();
    $consulting_articles = Article::byDepartment('Consulting')->get();

    return view('welcome', 
        [
        'loans_articles' => $loans_articles, 
        'digital_articles' => $digital_articles, 
        'consulting_articles' => $consulting_articles, 
        ]);

}

As you can see I'm returning this data to the welcome blade.

In my nav bar I tried

@if(count($loans_articles) > 0)
            @foreach($loans_articles as $ls)

        <!--for each loop which grabs the articles with department Loans-->
        <li><a href="/article/{{ $ls->id }}">{{  $ls->title }}</a></li>

            @endforeach
        @endif

But as soon as you navigate away from the home page the nav bar doesn't know what $loans_article is.

Is there a clean way to pass this data to the master blade navigation without sending the same data to every subview?

if you would like to share data with all of your blade templates, a simple way is trough appServiceProvider.php and boot method. you can find this file in app/Providers/AppServideProvider.php and do the changes like bellow:


namespace App\Providers;

use Illuminate\Support\Facades\View;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }

    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        View::share('key', 'value');
    }
}

after that you can access to the value in all blade files using {{ $key }}

note: do not forget to use Illuminate\Support\Facades\View in top of the class

<?php $contact = DB:table('tbl_contact')->get(); ?>

Use this code in master.blade.php in top section And Use such as 

<a href='{{ $contact[0]->fbLink ? $contact[0]->fbLink : " " }}'>

The way I tend to achieve this is by making a variable available to every view in this way:

All of your controller should extend a base controller, which is usually located in app/Http/Controllers/Controller.php. Inside this controller you can put some code that will be used by all extending controllers.

In this base controller you can make a variable available to all views, like this...

class Controller extends BaseController
{
    public function __construct()
    {
        // Load your objects
        $loans_articles = Article::byDepartment('Loans')->get();

        // Make it available to all views by sharing it
        view()->share('loans_articles', $loans_articles);
    }
}

All of your controllers must extend this controller for this to work.

If any of your controllers have their own constructors, you must also make sure to call parent::__construct() to ensure the above code is run. If your controllers don't have their own constructors, you can omit calling parent::__construct().

public class HomeController extends Controller
{
    public function __construct()
    {
        parent::__construct();

        // Your constructor code here..
    }
}

This way you should be able to use $loans_articles in all of your views.

You must use View Composer to achieve what you are trying to do :
