Basic to complex request method in laravel

Basic request $name = $request->input('name');

 Different method public function update(Request $request, $id) { // }

 Accessing The Request Via Route Closures Need to use the illuminate command, via route closures 

use Illuminate\Http\Request;

 Route::get('/', function (Request $request) { // });

 if ($request->is('admin/*')) { // }

 // Without Query String...
$url = $request->url(); //

With Query String...

$url = $request->fullUrl();

 Retrieving the method

 $method = $request->method();

 if ($request->isMethod('post')) { // }

 Has clause if ($request->has('name')) { // }

 Flashing Input Then Redirecting Lot to learn:

 return redirect('form')->withInput();

 return redirect('form')->withInput( $request->except('password') ); <input name="username" type="text" value="{{ old('username') }}" />
