Unable to Pass Variable from Controller to Drop Down - laravel

Question

I'm trying to get data from a table called solutions and view the solution names in a dropdown list on a form called products.
I've created a provider called DynamicDropdown in App/Providers.
<?php
namespace App\Providers;
use App\Dropdown;
use Illuminate\Support\ServiceProvider;
class DynamicDropdown extends ServiceProvider
{
public function boot()
{
view()->composer('*', function ($view) {
$view->with('product_array', Dropdown::all());
});
}
}
Controller
<?php
namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Providers\DynamicDropdown;
use App\Product;
use Illuminate\Http\Request;
class ProductsController extends Controller
{
public function index(Request $request)
{
$select = [];
foreach ($view as $data) {
$select [$data->id] = $data->solutionname;
}
return view('products.products', compact('select'));
}
}
I've called the select variable in the view but unfortunately, I'm getting an undefined variable error.
Blade
<div class="form-group <?php echo e($errors->has('solution') ? 'has-error' : ''); ?>">
<?php echo Form::label('solution', 'Solution', ['class' => 'control-label']); ?>
<?php echo Form::select('solution', $select, null,
('' == 'required') ? ['class' => 'form-control', 'required' => 'required'] : ['class' => 'form-control']); ?>
<?php echo $errors->first('solution', '<p class="help-block">:message</p>'); ?>
</div>
Error Message is...
ErrorException thrown with message "Undefined variable: select (View:
E:\Laravel\IBMint\resources\views\products\products\form.blade.php)
I tried many ways to fix it. But still could not find a solution. Appreciate if someone could assist.
Thank You.

It is because you are actually calling the $select variable on the wrong form. You return a view
return view('products.products', compact('select'));
which means get the view products.blade.php on the folder products under the view folder.
and based on the error you put the $select variable on the form.blade.php.
Fix will be you return the view form.blade.php like this.
return view('products.products.form', compact('select'));
