Laravel: Drop down options pulled from database in Master blade template are not showing on other pages

I have created a menu in master blade template in Laravel and have extended that to the other pages. That menu has a dropdown, with several options, that get fetched from the database. While, this works on the master template. It throws the same error on rest of the pages.

How should I fix this?

Here’s the error:

"ErrorException
Undefined variable: types (View: /Applications/MAMP/htdocs/bootstrap/laravel-project.app/resources/views/layouts/master.blade.php)"

Here’s the web.php code:

Route::get('/master', [MenuController::class, 'show'])
    ->name('master.show');

Controller.php

    <?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use AppModelsDoshaType;

class MenuController extends Controller
{
    public function show(){
           
        $types = DoshaType::all();
    
        return view('layouts/master', compact('types'));
        
    }

}

                                        <a class="dropdown-item" href="#">{{ $type->dosha }} </a>
                                    @endforeach
                                </div>

Answer

You need to create a global function for that because every page doesn’t have $type data. create the function in the helper file.

function types(){
    $types = DoshaType::all();
    return $type;
}

Now in the master file call this function.

@php $types = types(); @endphp
@foreach ($types as $type)                                        
    <a class="dropdown-item" href="#">{{ $type->dosha }} </a>
@endforeach

Another way make this query in your blade file

@php $types = AppDoshaType::all(); @endphp
@foreach ($types as $type)                                        
    <a class="dropdown-item" href="#">{{ $type->dosha }} </a>
@endforeach
