Laravel 5 Add another parameter to check on login - laravel

Question

I'm using Laravel 5.3 and I used the make:auth to scaffold the registration/login system. I was wondering how do I add another parameter to check on the login, besides checking if the username and password correspond to the matching DB row?
EDIT: I tried looking online and I found I could change it in the Auth::Attempt line but those are all for Laravel 5.2 and below. The LoginController has this:
use AuthenticatesUsers;
protected $redirectTo = '/home';
public function __construct()
{
$this->middleware('guest', ['except' => 'logout']);
}
From what I understand, that redirects to the middleware RedirectIfAuthenticated, but then that middleware is like this:
public function handle($request, Closure $next, $guard = null)
{
if (Auth::guard($guard)->check()) {
return redirect('/home');
}
return $next($request);
}
I'm almost sure I have to add a custom guard, but even at the docs I looked online, it was kinda confusing.. Anybody have a link that explains this really well? Or maybe a sample code?

Yes, you could do it by overriding a AuthenticatesUsers's credentials() method in your LoginController.php
use Illuminate\Http\Request;
protected function credentials(Request $request)
{
$credentials = $request->only($this->username(), 'password');
$credentials['active'] = 1;
return $returnArray;
}
This example is of most common use case where user can login only if his account is active.
If you want to use other table instead of users, you need to customize guard
Add one in config/auth.php
'guards' => [
'user' => [
...
],
'customer' => [
'driver' => 'session',
'provider' => 'customers',
],
],
...
'providers' => [
'users' => [
...
],
'customers' => [
'driver' => 'eloquent',
'model' => App\Customer::class,
],
],
And then, add this in your LoginController.php
use Illuminate\Support\Facades\Auth;
protected function guard()
{
return Auth::guard('customer');
}
As specified in docs, you can use the same in RegisterController and ResetPasswordController as well.
