Laravel post radio button - laravel

Question

I want to send the value of the radio button to the class, the problem is that the name is different each time because I have an id to finally group it in the view, how can I refer to this name?
#foreach($users as $user)
<tr>
<td>{{ $user->id }}</td>
<td>{{ $user->name }}</td>
<td>{{ $user->email }}</td>
<td>
<form method="post" action="updateprivileges/{{$user->id}}">
#csrf
<div class="row">
<div class="col-4">
<input type="radio" value="1" class="flat" name="privileges_{{ $user->id }}" {{ $user->privileges[0]['roles_id'] == '1' ? 'checked' : '' }} > <div class="uprawnienia-margin">Administrator</div>
</div>
<div class="col-4">
<input type="radio" value="2" class="flat" name="privileges_{{ $user->id }}" {{ $user->privileges[0]['roles_id'] == '2' ? 'checked' : '' }} > <div class="uprawnienia-margin">Serwisant</div>
</div>
<div class="col-4">
<input type="radio" value="3" class="flat" name="privileges_{{ $user->id }}" {{ $user->privileges[0]['roles_id'] == '3' ? 'checked' : '' }} > <div class="uprawnienia-margin">Monter</div>
</div>
</div>
<input type="submit" name="add" class="btn btn-primary input-lg" value="Przeslij" />
</form>
</td>
</tr>
#endforeach

You have dynamic name attributes. You should change this to static ones, so you can always receive the correct value in your controller where you receive the payload. And don't forget to use the correct HTTP Method.
<form method="post" action="{{ URL::to('/updateprivileges/' . $user->id)}}">
#csrf
<input type="radio" name="privilege" value="1"> Administrator</br>
<input type="radio" name="privilege" value="2"> Serwisant</br>
<input type="radio" name="privilege" value="3"> Monter</br>
<input type="submit" value="Przeslij">
</form>
Declare the route in routes/web.php:
// put method
Route::post('updateprivileges/{id}', 'UserController#updatePrivileges');
Now, your UserController receives the privilege variable in the Request $request:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class UserController extends Controller
{
public function updatePrivileges(Request $request, $id)
{
$privilege = $request->input('privilege');
dd($privilege); // dumps $privilege and dies
// more code, perhaps save the users privilege
}
}
I hope this helps.
