Laravel 5.4 change user role - php

Question

I trying make changing role in my panel admin. But when i made it my form dont sending post request. Now only working showing user role. I cant fix it becouse when i click button to switch i dont get any error and role is not changing.
I use HttpRequester when i use url /admin/change its showing this error:
MethodNotAllowedHttpException in RouteCollection.php line 233
There is my code:
View:
#extends('layouts.app')
#section('content')
<h2>Panel Admina</h2>
<div class="panel-group">
<div class="panel panel-default">
<div class="panel-body">
<table class="table">
<thead>
<tr>
<th>Id</th>
<th>Imię</th>
<th>Nazwisko </th>
<th>E-mail </th>
<th>Nr.tele </th>
<th>Użytkownik </th>
<th>Moderator </th>
<th>Admin </th>
</tr>
</thead>
<tbody>
#foreach($users as $user)
<tr>
<form action="{{route('change')}}" method="post">
{{ csrf_field() }}
<td>{{ $user->id }}</td>
<td>{{ $user->name }}</td>
<td>{{ $user->lastname }}</td>
<td>{{ $user->email }}<input type="hidden" name="email" value="{{ $user->email }}"></td>
<td>{{ $user->phonenumber }}</td>
<td><input type="checkbox" {{ $user->hasRole('User') ? 'checked' : '' }} name="role_user"/></td>
<td><input type="checkbox" {{ $user->hasRole('Moderator') ? 'checked' : '' }} name="role_moderator"/></td>
<td><input type="checkbox" {{ $user->hasRole('Admin') ? 'checked' : '' }} name="role_admin"/></td>
<td><input type="submit" class="btn btn-default btn-sm" value="Przydziel rolę"></td>
</form>
</tr>
#endforeach
</tbody>
</table>
</div>
</div>
</div>
#endsection
Controller:
public function change(Request $request)
{
$user = User::where('email', $request['email'])->first();
$user->roles()->detach();
if ($request['role_user']) {
$user->roles()->attach(Role::where('name', 'User')->first());
}
if ($request['role_moderator']) {
$user->roles()->attach(Role::where('name', 'Moderator')->first());
}
if ($request['role_admin']) {
$user->roles()->attach(Role::where('name', 'Admin')->first());
}
return redirect()->back();
}
Routing:
Route::get('/admin', [
'uses' => 'AdminController#index',
'middleware' => 'roles',
'roles' => ['Admin']
]);
Route::post('/admin/change', [
'uses' => 'AdminController#change',
'as' => 'change',
'middleware' => 'roles',
'roles' => ['Admin']
]);
I really dont know how i can resolve my problem.

Answer 1

try to pass the user id to your route and your form action and instead of post make it put for example:
<form action="{{route('change', $user->id)}}" method="post">
and in your route:
Route::put('/admin/change/{id}', [
'uses' => 'AdminController#change',
'as' => 'change',
'middleware' => 'roles',
'roles' => ['Admin']
]);
and in your controller:
public function change(Request $request, $id)
