Here is my code Blade.php

<form name="editAttributeForm" id="editAttributeForm" method="post" action="{{url('admin/edit-attributes/'.$productdata['id'])}}" enctype="multipart/form-data">

Answer

Upgrade your ProductsController.php as following, it might work.

public function editAttributes(Request $request, $id)
    {
        if ($request->isMethod('post')) {
            $data = $request->all();

            foreach ($data['attrId'] as $key => $attr) {
                if (!empty($attr)) {
                    ProductsAttribute::where(['id' => $data['attrId'][$key]])
                        ->update(['price' => $data['price'][$key], 'stock' => $data['stock'][$key]]);
                }
            }

            // You can check all attributes, updated or not if you wish
            
            $success_message = "Product attributes has been updated successfully!";
            session::flash("attSuccess_message", $success_message);
            return redirect()->back();
        }
    }
