the conroller:

class SortController extends MainController{

public function sortByASC( $category_url,Request $request)

{

$sort = $request->get('sort', 'asc');

if ($category=Categorie::where('url','=', $category_url)){ $products = Product::orderBy('price', $sort) ->get();

return view('content.sort')->with('products', $products) ;

}} view

<form id="order-product-form" method="get" action="{{url('shop/{category_url}/sort=ASC')}}"enctype="multipart/form-data">

      
@if ($products)   
@foreach($products as $product)
