How to update record 'pay' laravel? - php

Question

I'm trying to update my 'pay' record in the DB after pressing a button in a table row, but it shows this error when pressing the button:
ErrorException in 0db55b8fee884912074e1a4700061051aeb18bcc.php line
15: Undefined variable: users (View:
/Users/mauricio/code/cnr/resources/views/pages/users.blade.php)
I don't know why it gives me that error when I have use the users variable before in the blade file.
Here is my Registration Controller:
<?php
namespace App\Http\Controllers;
use DB;
use App\User;
class RegistrationController extends Controller
{
public function updatePay(User $id)
{
DB::table('users')->where('id', $id)->update(['pay' => 1]);
return view('pages.users');
}
}
Welcome controller:
public function usersAdmin()
{
$users = DB::table('users')->get();
return view('pages.users', compact('users'));
}
Routes file:
// for admin only
Route::get('/users', 'WelcomeController#usersAdmin');
Route::post('/users/{id}', 'RegistrationController#updatePay');
Here is my view
#extends('layouts.master')
#section('content')
<table class="highlight">
<thead>
<tr>
<th data-field="id" hidden="">ID</th>
<th data-field="name">Nombre</th>
<th data-field="last_name">Apellidos</th>
<th style="text-align: right;">Acciones</th>
</tr>
</thead>
<tbody>
#foreach($users as $user)
<tr>
<td>{{$user->id}}</td>
<td>{{$user->name}}</td>
<td>{{$user->last_name}}</td>
<td style="text-align: right; width: 30em">
#if( $user->isAdmin )
{{"ADMINISTRADOR"}}
#elseif( $user->pay )
<a class="waves-effect waves-light btn yellow darken-2"><i class="material-icons left" style="margin:0">create</i></a>
<a class="waves-effect waves-light btn red darken-1"><i class="material-icons left" style="margin:0">delete</i></a>
#else
<form method="POST" action="/users/{{$user->id}}">
{{ csrf_field() }}
<button type="submit" class="waves-effect waves-light btn green lighten-1"><i class="material-icons left" style="margin:0">done</i></button>
</form>
#endif
</td>
</tr>
#endforeach
</tbody>
</table>
#endsection

You need to retrieve users and send it to the view similar like this:
Controllers:
public function methodName()
{
$users = User::all();
return view('path.to.view')->with(compact('users'));
}
Also, You have two choice to use:
First
public function updatePay($id)
Second
public function updatePay(User $user)
{
DB::table('users')->where('id', $user->id)->update(['pay' => 1]);
and instead of return view('pages.users'); use return redirect()->url('users'); in the updatePay method.
