Laravel 5.1 $this->validate(...) throws error - php

Question

I'm trying to add validation to my resource controller using the laravel's validation (http://laravel.com/docs/5.1/validation) but I get this error:
ErrorException in ValidatesRequests.php line 30:
Argument 1 passed to App\Http\Controllers\Controller::validate() must be an
instance of Illuminate\Http\Request,
instance of Illuminate\Support\Facades\Request given,
called in
/Users/lextoc/Documents/Sites/partyrecycler/app/
Http/Controllers/MarkerController.php on line 30 and defined
This is the controller:
namespace App\Http\Controllers;
use Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Marker;
class MarkerController extends Controller
{
...
public function create()
{
return view('markers.create');
}
public function store(Request $request)
{
$this->validate($request, [
'name' => 'required|max:255',
'x' => 'required',
'y' => 'required',
]);
$marker=Request::all();
Marker::create($marker);
return redirect('markers');
}
...
}
And the view:
<h1>Create marker</h1>
#if (count($errors) > 0)
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
{!! Form::open(array('route' => 'markers.store')) !!}
{!! csrf_field() !!}
<div>
Name
<input type="text" name="name">
</div>
<div>
x
<input type="text" name="x">
</div>
<div>
y
<input type="text" name="y">
</div>
<div>
<button type="submit">Create</button>
</div>
{!! Form::close() !!}
I don't know why it's using the wrong Request class, and why are there two being used in the controller?

Answer 1

The error is due to your include headers:
Try
use Illuminate\Http\Request;
Instead of
use Request;
Example:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Marker;
