Laravel 5.4 not registrating users to database, - mysql

Question

I'm simply trying to make my register form submit to my database, but my problem is you enter the info to the form press submit and it just reloads the page and does not send anything to the database.
originally it would submit what i entered but when you went to login it would just reload the page and not redirect, so i changed some stuff one thing lead to another now its not doing anything and i cannot pin-point the problems.
RegisterController.php
namespace App\Http\Controllers\Auth;
use App\Admin;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
class RegisterController extends Controller
{
use RegistersUsers;
/**
* Where to redirect users after registration.
*
* #var string
*/
protected $redirectTo = ('index');
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
$this->middleware('guest:admin');
}
