سلام ,

من داخل فرم ثبت نام دو فیلد phone_number و address گذاشتم و در RegisterController  متد validator() و create()  رو ویرایش کردم (mass assignment اوکی هست.)

RegisterController

<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use App\Models\User;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
class RegisterController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Register Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users as well as their
    | validation and creation. By default this controller uses a trait to
    | provide this functionality without requiring any additional code.
    |
    */
    use RegistersUsers;
    /**
     * Where to redirect users after registration.
     *
     * @var string
     */
    protected $redirectTo = '/products';
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }
    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'phone_number' => ['required','string','unique:users.phone_number'],
            'address'=> ['required','string'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);
    }
    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\Models\User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'address' => $data['address'],
            'phone_number' => $data['phone_number'],
            'password' => Hash::make($data['password']),
        ]);
    }
}

و من به این ارور خوردم :

InvalidArgumentException
Database connection [users] not configured.
http://127.0.0.1:8000/register
