Php – Laravel Auth::attempt() always false

authenticationlaravelPHP

I recently started learning Laravel (PHP MVC framework) and I've been having a lot of issues with Authenticating a user with: Auth::attempt($credentials).

I'll put my code snippets below. In my mySQL database I have a record with the following key=>values:
id=>1, username=>'admin', password=>'admin', created_at=>0000-00-00 00:00:00, updated_at=>0000-00-00 00:00:00

The Validator passes, but the Auth:attempt always fails.

If the code below and my little explanation isn't enough, please let me know! 🙂

Routes.php:

Route::get('login', 'AuthController@showLogin');
Route::post('login', 'AuthController@postLogin');

AuthController:

public function showLogin(){

    if(Auth::check()){
        //Redirect to their home page
    }
    //Not logged in
    return View::make('auth/login');
}

public function postLogin(){

    $userData = array(
        'username' => Input::get('username'),
        'password' => Input::get('password')
    );

    $reqs = array(
        'username' => 'Required',
        'password' => 'Required'
    );

    $validator = Validator::make($userData, $reqs);

    if($validator->passes() && Auth::attempt($userData)){
        return Redirect::to('home');
    }
    return Redirect::to('login')->withInput(Input::except('password'));
}

I believe the attempt() method will hash the password that is sent in. Seeing as your DB entry's password is 'admin' in plaintext, that would fail. Save your password with Hash::make($password); and i believe your problem should be solved.

Php – Auth::user() returns null

I faced a situation where Auth::user() always returns null, it was because I was trying to get the User in a controller's constructor.

I realized that you can't access the authenticated user in your controller's constructor because the middleware has not run yet.

As an alternative, you can define a Closure based middleware directly in your controller's constructor.

namespace App\Http\Controllers;

use App\User;
use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\Controller;

class ProjectController extends Controller
{
    protected $user;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware(function ($request, $next) {

            $this->user = Auth::user();

            return $next($request);
        });
    }
}

Php – Laravel 5 Auth::attempt always return false

You can try this way..

When you registering user use bcrypt to encrypt your password before seving them to database

$password = bcrypt($input['password']);
            // OR
$psssword = bcrypt(Request::get('password'));

And because you are using username in place of default email

Your LoginController..

namespace App\Http\Controllers;

use Request;
use Auth;
use App\Http\Requests;
use Hash;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Redirect;
class LoginController extends Controller
{

 use AuthenticatesAndRegistersUsers;

 public function loginUsername()
 {
     return 'username';
 }

 public function login(){
        $uname = Request::get('username');
        $password = Request::get('password');
            if (Auth::attempt(array('username' => $uname, 'password' => $password))){
                return "success";
            }
            else {        
                return "Wrong Credentials";
            }
        }
}

Hope this will work.
