Laravel 5.6 pass variable to view from middleware

Question

Is there a way to pass a variable to the view with middleware?
I was able to do this using a session, but this didn't resolve my problem, so I'm asking for this.

What are you trying to accomplish actually? Mingling request middleware with a view is the worst thing you can do. Don't mix responsibilities. — Mike Doe, May 19 '18 at 13:32

Middleware is used to modify the request.

If you have some dynamical data that you use for each view then its best to use a service provider and not middleware.

For example, you may have on each page some meta data and each view includes a header.blade.php which may look like this:

<head> <meta name="{{$meta_key}}" content="{{$meta_desc}}"> </head>

Then you could create a service provider

 public function boot()
 {
    view()->composer('view', function () {
        $slug = request()->path();

        $meta = \MetaTags::where('slug' ,'=',$slug)->first();

        $view->with('metatag', $meta->tag);
    });
 }

Thanks bro! https://stackoverflow.com/questions/28608527/how-to-pass-data-to-all-views-in-laravel-5 by the way, in the left question there are answers suggest using middleware (if I'm not misunderstanding the question), do you think middleware is also a solution? – shintaroid Mar 04 '20 at 10:38

Using the following code, you can easily access the data in the view:

view()->share('my_variable', $variable);

Now you can use {{$my_variable}} in your views.

You can merge the variable into the request, read it from the request on the controller, and then pass that on to the view.

For example, in the middleware:

public function handle($request, Closure $next)
{
    $foo = 'bar';
    $request->merge(compact('foo'));

    return $next($request);
}

On the controller:

public function create(Request $request)
{
    $foo = $request->foo;
    return view('my.view', compact('foo'));
}

Then on the view, you can reference it as, e.g. {{ $foo }}.

Replace 'view' in composer by path where to you want send data

i.e. if you want to send to header.blade.php which is in partials folder,then replace 'view' as 'partials.header' .

After referring @adam answer and Laracasts episode 25 following code work for me:

\app\Providers\AppServiceProvider.php

Add following codes in boot() function :-

 view()->composer('partials.header', function ($view) {
            //

            $view->with('your_key', 'your_value');
        });

Now your data is available at project_name\resources\views\partials\header.blade.php as

{{$your_key}}

or

<?php echo $your_key; ?>
