For the given issue Here is my Controller

public function update(Request $request ,$id){

        print_r($request);
        return redirect()->back();
    }

View

{!! Form::model($website, ['method' => 'PATCH   ', 'route' => ['websites.update', $website->id]]) !!}`
<div class="form-group">


    </div>
{!! Form::submit('Update', ['class' => 'btn btn-primary']) !!}
{!! Form::close() !!}

Here My route

  Route::post('websites/{id}/update',
    ['as' => 'websites.update', 'uses' => 'WebsiteController@update']
);
