Laravel 9 Login with Username or Email

Sometimes you will see that there are many web applications and their user can login with a username or email. In this example, we will see how to login in laravel with email or username. For laravel 9 login with username or email, laravel provides some convenient helper function to create login with email or phone number laravel.

I will simply create a login request and login controller to show you the source code of laravel login using username or email. 

Now, update the LoginController with the following code: 

app\Http\Controllers\LoginController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests\LoginRequest;
use Illuminate\Support\Facades\Auth;

class LoginController extends Controller
{
    /**
     * Display login page.
     * 
     * @return Renderable
     */
    public function show()
    {
        return view('auth.login');
    }

    /**
     * Handle account login request
     * 
     * @param LoginRequest $request
     * 
     * @return \Illuminate\Http\Response
     */
    public function login(LoginRequest $request)
    {
        $credentials = $request->getCredentials();

        if(!Auth::validate($credentials)):
            return redirect()->to('login')
                ->withErrors(trans('auth.failed'));
        endif;

        $user = Auth::getProvider()->retrieveByCredentials($credentials);

        Auth::login($user);

        return $this->authenticated($request, $user);
    }

    /**
     * Handle response after user authenticated
     * 
     * @param Request $request
     * @param Auth $user
     * 
     * @return \Illuminate\Http\Response
     */
    protected function authenticated(Request $request, $user) 
    {
        return redirect()->intended();
    }
}

 

And now update the login request like below:

app\Http\Requests\LoginRequest.php

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Contracts\Validation\Factory as ValidationFactory;

class LoginRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'username' => 'required',
            'password' => 'required'
        ];
    }

    /**
     * Get the needed authorization credentials from the request.
     *
     * @return array
     * @throws \Illuminate\Contracts\Container\BindingResolutionException
     */
    public function getCredentials()
    {
        // The form field for providing username or password
        // have name of "username", however, in order to support
        // logging users in with both (username and email)
        // we have to check if user has entered one or another
        $username = $this->get('username');

        if ($this->isEmail($username)) {
            return [
                'email' => $username,
                'password' => $this->get('password')
            ];
        }

        return $this->only('username', 'password');
    }

    /**
     * Validate if provided parameter is valid email.
     *
     * @param $param
     * @return bool
     * @throws \Illuminate\Contracts\Container\BindingResolutionException
     */
    private function isEmail($param)
    {
        $factory = $this->container->make(ValidationFactory::class);

        return ! $factory->make(
            ['username' => $param],
            ['username' => 'email']
        )->fails();
    }
}
