Expand fields on artisan make:auth - laravel-5

Question

I have generated Laravel's authentication code using
php artisan make:auth
The auto-generated registration form provides the following fields:
Name, Email, and Password.
I'm trying to add First Name, Last Name instead of just Name. I've successfully created the DB Table and the form(view) with the fields. When I test and register a user the password and email fields are saved but not the First Name and Last Name.
My guess is that I'm missing a file that I have not modified.
What page defines the fields that get written into the database?
This is my validator and auth code in authcontroller:
/**
* 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, [
'first_name' => 'required|max:255',
'last_name' => 'required|max:255',
'email' => 'required|email|max:255|unique:users',
'password' => 'required|min:8|confirmed',
]);
}
/**
* Create a new user instance after a valid registration.
*
* #param array $data
* #return User
*/
protected function create(array $data)
{
return User::create([
'first_name' => $data['first_name'],
'last_name' => $data['last_name'],
'email' => $data['email'],
'password' => bcrypt($data['password']),
]);
}
If I change 'first_name' to 'name' on the controller and the database table it does save. Validator works well.

Answer 1

You need to go to you AuthController which should be in app/Http/Controllers/Auth.
In there you will need to change the validator() and create() methods to include firstname and lastname fields.
Hope this helps!

The modification that I was missing was on the user.php file:
<?php
namespace App;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'first_name', 'last_name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
}
The fields that I added needed to be included as protected $fillable. I made that change and everything is working.
