Hello Friends,

I would like to show you laravel fortify custom login. This article will give you a simple example of auth login function in laravel. Let's get started with laravel custom login function.

Sometimes we need to overwrite or custom code for the login method, so here I will give you a very simple example of how to overwrite auth default login function in laravel app.

You can use this example with laravel 6, laravel 7, laravel 8, and laravel 9 versions.

You can see bellow default route for login post method:

<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\LoginController;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::post('login', 'Auth\LoginController@login');

so, Basically you can create new method login into your LoginController and override auth method. let's add code like below:

app/Http/Controllers/LoginController.php

<?php

  
namespace App\Http\Controllers\Auth;

  
use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Auth;

   
class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

  
    use AuthenticatesUsers;

  
    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = RouteServiceProvider::HOME;

   
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

  
     /**
     * Write code on Method
     *
     * @return response()
     */
    public function login(Request $request)
    {
        $request->validate([
            'email' => 'required',
            'password' => 'required',
        ]);

     
        $credentials = $request->only('email', 'password');
        if (Auth::attempt($credentials)) {

  
            return redirect()->route('home');
        }

    
        return redirect("login")->withSuccess('Oppes! You have entered invalid credentials');
    }
}

i hope it can help you....
