Load dynamic content in navbar

Question

I have a select in navbar with the cities registered in the bank. For this I am using ajax to load them.

But I wanted a solution without having to use ajax, but also without having to assemble the query in each method that points to the view. Would have as?

Yes, no need to use AJAX for that. The Laravel has a function called view composer, where it is possible to do exactly what you need.

I will give a brief summary of the two files needed and leave the link to the documentation, where you can consult the correct syntax.

First you have to create inside the directory app/Http, the file that will contain the code that will be displayed in the view. I advise you to create a folder to get more organized.

$cidades = Cidades::get();
$view->with('cidades', $cidades);

Then you need to create a file inside app/Providers, who will be responsible for calling the file created earlier.

view()->composer(
    ['nome-view-navbar'], 'App\Http\nome-pasta-criada\nome-arquivo-cidades'
);

Here is the link to the documentation: https://laravel.com/docs/5.6/views#view-Composers

As you did not specify the version of your project, I put the link to the last.
