Laravel: passing a variable to multiple views

Question

I would like to make the menu dinamically, so instead showing "FILMS OF THE MONTH" it shows "FILMS OF DECEMBER" (see the image); being December the current month that update itself each month

My problem is that the menu does not belongs to an specific route/controller, therefore I can not pass the variable like I do with other routes. Example:

    $month = Carbon::now()->format('F');
    return view('partials._nav')
            ->withMonth($month);

I could "solve" that problem passing the month to ALL controllers/routes, but I am repeating many times the same code.

My questions are

1- Is there any way in Laravel to pass a variable to a kind of rootstate (like in Angular) so, I keep the variable available in All routes of my application?

2- Is there any way that I could return a variable to more than one view? So I just pass the variable to all views possible like:

return view('films.all', 'films.show', 'films.index', 'actors.show', 'actors.index')
                ->withMonth($month);

Any idea would be appreciated

UPDATE

Finally I have the solution:

public function boot()
{
    View::composer('*', function ($view) {
        $month = Carbon::now()->format('F');

        $view->withMonth($month);
    });
}

You can use the share() method to share the data to multiple view. Place the following code in your boot() method of App/Providers/AppServiceProvider:

public function boot()
{
    view()->share('key', 'value');
}

I try to understand what does it mean, but I have not clue how to use this in my solution. What is key?, what is value? I need to pass a variable $month that dynamically changes each month (january, february..) into all views.

You can use the AppServiceProvider, you pass a variable through the layout that you extends.

Your code will be:

public function boot()
{
    View::composer('*', function ($view) {
        $var = 'value';

        $view->with('var', $var);
    });

    View::composer('*', function ($view) {
        $month = Carbon::now()->format('F');

        $view->withMonth($month);
    });
}

And you need to use the following class: use Illuminate\Support\Facades\View;

Hope this works!

I used this solution , changing the line $var = 'value" with this -> "$var = Carbon::now()->format('F');" Since I want the value to be dynamic. I added use Carbon\Carbon at the top but the solution give me an error message: "FatalErrorException in AppServiceProvider.php line 26: Class 'App\Providers\View' not found"

It did not work. I get the error: Undefined variable: month (View: C:\Users\rra\Documents\Personal\Kino\resources\views\partials_nav.blade.php). I think the problem is that I am trying to pass the variable $month into the layout, outside all the views. See the image, I updated the question

@RafaelMunoz I added the code, this will pas to all views in your view folder the variable. Now it will also pass to the views which extends the layout.

It finally worked, but I had to make some changes. See the update in the question

@FarshidRezaei return view(‘admin.dashboard’, compact(‘varname’)); remind to not use the $ in the compact method.

Another way is to use Laravel Session. You can save variable value in session and get it anywhere.

 //To Save value in Session
   $month = 'January';
   Session::put('currentMonth', $month);

 //To Get value from Session
   if((Session::has('currentMonth'))) {
       $month_var = Session::get('currentMonth');
    }
