As I will cover this Post with live Working example to develop laravel roles and permissions, so the access control level in laravel for this example is following below.

roles namely Main Admin, Agent(Moderator), and Users Set up migrations:new role column

Schema::create('users', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->string('email')->unique();

            <option value="admin">Admin</option>
            <option value="agent">Agent</option>
            <option value="customer">Customer</option>
        </select> 
    </div>
</div>

Change The User Model

User.php

protected $fillable = [
    'name', 'email', 'password','role',
];

app/Http/Controllers/Auth/RegisterController.php

protected function validator(array $data)
{
    return Validator::make($data, [
        'name' => 'required|string|max:200',
        'email' => 'required|string|email|max:200|unique:users',
        'password' => 'required|string|min:6|confirmed',
        'role' => 'required|in:admin,agent,customer', //Laravel validate role input
    ]);
}

create() simple method on Laravel Controller

protected function create(array $data)
{
    return User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => bcrypt($data['password']),
        'role' => $data['role'],
    ]);
}

Step 3 :Laravel Set-up middlewares:

run this comands

php artisan make:middleware Admin
php artisan make:middleware Agent
php artisan make:middleware Customer

app/Http/Middleware/Admin.php

use Auth; //at the top
 
function handle($request, Closure $next)
{
    if (Auth::check() && Auth::user()->role == 'admin') {
        return $next($request);
    }
    elseif (Auth::check() && Auth::user()->role == 'agent') {
        return redirect('/agent');
    }
    else {
        return redirect('/customer');
    }
}

Agent.php:

use Auth; //at the top
 
function handle($request, Closure $next)
{
    if (Auth::check() && Auth::user()->role == 'agent') {
        return $next($request);
    }
    elseif (Auth::check() && Auth::user()->role == 'customer') {
        return redirect('/customer');
    }
    else {
        return redirect('/admin');
    }
}

Customer.php:

use Auth; //at the top
 
function handle($request, Closure $next)
{
    if (Auth::check() && Auth::user()->role == 'customer') {
        return $next($request);
    }
    elseif (Auth::check() && Auth::user()->role == 'agent') {
        return redirect('/agent');
    }
    else {
        return redirect('/admin');
    }
}

app/Http/Kernel.php $routeMiddleware

protected $routeMiddleware = [
    // ...
    'admin' => 'AppHttpMiddlewareAdmin',
    'agent' => 'AppHttpMiddlewareAgent',
    'customer' => 'AppHttpMiddlewareCustomer',
];

routes/web.php:

Route::get('/admin', function(){
    echo "Hello Admin";
})->middleware('auth','admin');
 
Route::get('/agent', function(){
    echo "Hello Agent";
})->middleware('auth','agent');
 
Route::get('/customer', function(){
    echo "Hello Customer";
})->middleware('auth','customer');

controller’s constructor

public function __construct()
{
    $this->middleware('auth');    
    $this->middleware('admin');
}

Redirect User After Log-in:

Add this to your LoginController.php:

protected function redirectTo( ) {
    if (Auth::check() && Auth::user()->role == 'customer') {
        return redirect('/customer');
    }
    elseif (Auth::check() && Auth::user()->role == 'agent') {
        return redirect('/agent');
    }
    else {
        return redirect('/admin');
    }
}
