Sending parameters in LARAVEL 5.8 - php

Question

I need to send parameters to my "show" function in Laravel 5.8 via a select HTML tag but I am not able. I've been there for several days and I'm a little desperate.
In the action of the Form I put the following:
This is the route: {{route('users.show', ['id' => {{$list->id}}])}} but since the variable does not exist, it gives me error. Another option I considered is to use a link <a href='#'></a> where '#' is the route. But $list->id returns the last ID in the List in the Users table.
How can I capture the selected data in my drop-down list and send it as a parameter to the controller's show function?
Route::group(['middleware' => ['verified']], function () {
// Panel de control
Route::get('/home', 'HomeController#index')->name('home');
Route::resource('users', 'UserController');
This is the Controller:
public function index()
{
# Panel de control
$log = Auth::id();
$users = User::orderBy('created_at', 'asc')->where('id',$log)->with('imagenes')->get()->toArray();
$users=Array_chunk($users,3,true);
$imgBorrado = array();
$imgB=null;
//dd($imgBorrado);
$user=User::find('id');
$userslist=User::all();
//$list=User::orderBy('created_at', 'asc')->get('id','name')->toArray();
//dd($userslist);
return view('users.index', compact('user','users','imgBorrado','imgB','userslist'));
}
public function show($id)
{
# Mostrar usuario con sus atributos
$user=User::find($id);
dd($id);
return view('users.show', compact('user'));;
}
This is the view:
<form method="POST" action="#" id="selector" enctype="multipart/form-data">
#csrf
<label for="desplegable" class="col-md-4 col-form-label text-md-right">{{ __('Productor:') }}</label>
<div class="col-md-6">
<select class="form-control{{ $errors->has('id') ? ' is-invalid' : '' }}" id="desplegable" name='workers[]' required>
<option selected>...</option>
#foreach($userslist as $list)
<option value="{{$list->id}}">
{{$list->name}}
</option>
#endforeach
</select>
#if ($errors->has('id'))
<span class="invalid-feedback" role="alert">
<strong>{{ $errors->first('id') }}</strong>
</span>
#endif
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Cerrar</button>
<button type="submit" class="btn btn-primary" form="selector" Value="desplegable">Seleccionar Perfil</button>
</div>
Thanks you!

Answer 1

You cannot have access to the ID of the selected user in your <form> tag.
One option would be to catch the request in your show() method and then fetch the desired user through it.
Here is an example based on your code:
// In your Controller (don't forget to import Request facade)
use Illuminate\Support\Facades\Request
public function show(Request $request)
{
$userId = $request->get('workers'); // Name of the select input
$user = User::find($userId);
return view('users.show', compact('user'));
}
You can even validate the Request passed to the show() method. Read more about that here

Answer 2

I add the modification here:
public function show(Request $request)
{
# Nombre del select (input)
$userId = $request->get('workers');
# Mostrar usuario con sus atributos
$usu=User::find($userId);
foreach($usu as $user) {
$user->name;
}
return view('users.show', compact('user'));;
}
