route

route::post('/create_user', 'auth\registercontroller@createuser'); 

method

public function createuser(request $request) {     dd($request->all());  } 

possible error "/"

<form role="form" id="reg-form" method="post" class="form-horizontal" action="{{ url('/create_user') }}"> 

so plz remove like

<form role="form" id="reg-form" method="post" class="form-horizontal" action="{{ url('create_user') }}"> {{-- '/' removed --}} 

and in

route::post('create_user', 'auth\registercontroller@createuser'); // '/' removed 

it worked me.
