Laravel Simple Multi-Model Authentication

readme.md

This is a simple method of implementing multi-model / guard authentication into laravel using the default laravel authentication structure. (NOTE: passport // API integration not included yet)

1. php composer make:auth
2. cp App/User.php App/Admin.php
3. Edit App/Admin.php and change the class name to Admin
4. Edit config/auth.php and add the following

...
'guards' => [
...
    'admin' => [
        'driver' => 'session',
        'provider' => 'admin',
    ],
    'admin_api' => [
        'driver' => 'passport',
        'provider' => 'admin',
        'hash' => false,
    ],
],
...
'providers' => [
...
    'admin' => [
        'driver' => 'eloquent',
        'model' => App\Admin::class,
    ],
],
...
'passwords' => [
...
    'admin' => [
        'provider' => 'admin',
        'table' => 'password_resets',
        'expire' => 60,
    ],
],

5. php make:middleware AuthGuard
6. Edit app/Http/Middleware/AuthGuard.php to contain the following file.
7. Edit app\Http\Kernel.php

...
protected $middlewareGroups = [
    'web' => [
...
        \App\Http\Middleware\AuthGuard::class,
    ],
...

AuthGuard.php

<?php

namespace App\Http\Middleware;

use App\Admin;
use Closure;
use Illuminate\Support\Facades\Auth;

class AuthGuard
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if($request->session()->has('guard'))
            config(['auth.defaults.guard' => $request->session()->get('guard','users')]);

        if($request->is('login') && $request->isMethod('post')){
            if(Admin::where('email',$request->get('email'))->count() > 0){
                config(['auth.defaults.guard' => 'admin']);
                $request->session()->put('guard','admin');
            }
        }


        return $next($request);
    }
}
