Today we are going to do login with username or email in Laravel using only one field. Let’s follow these steps:

Table of Contents

1. Make Auth and Update Users Migration File
2. Update User Model
3. Update RegisterController
4. Update LoginController
5. Update Register Blade Template
6. Update Login Blade Template
7. The Output

Step 1 : Make Auth and Update User Migration File

At first, run this artisan command to create auth scaffolding:

php artisan make:auth

Open users migration from datbase>migrations and add username field:

public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name');
        $table->string('username')->unique();
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });
}

Let’s execute the migrate command:

php artisan migrate

Step 2 : Update User Model

We need to add username in the $fillable array. Open User model from app folder and do like this:

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

Step 3 : Update RegisterController

Go to app>Http>Controllers>Auth and open RegisterController. We have to add username field in validator() & create() function.

protected function validator(array $data)
{
    return Validator::make($data, [
        'name' => ['required', 'string', 'max:255'],
        'username' => 'required|string|max:20|unique:users',
        'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
        'password' => ['required', 'string', 'min:6', 'confirmed'],
    ]);
}

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

Step 4 : Update LoginController

Open LoginController from the same path of RegisterController. Here we are going to update login() function to determine email or username from one input. We need to use Illuminate\Http\Request; too.

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
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 = '/home';

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

    /**
     * Override login function for login with email or username.
     */
    public function login(Request $request)
    {
        $this->validate($request, [
            'email' => 'required',
            'password' => 'required|min:6'
        ]);

        $email = $request->get('email');
        $password = $request->get('password');
        $remember_me = $request->remember;

        $login_type = filter_var($email, FILTER_VALIDATE_EMAIL) ? 'email' : 'username';

        if (Auth::attempt([$login_type => $email, 'password' => $password], $remember_me)) {
            //Auth successful here
            return redirect()->intended($this->redirectPath());
        }

        return redirect()->back()
            ->withInput()
            ->withErrors([
                'login_error' => 'These credentials do not match our records.',
            ]);
    }
}

Step 5 : Update Register Blade Template

Open register blade file from resources>views>auth folder. We have to username field here. Let’s do this:

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div class="card-header">{{ __('Register') }}</div>

                <div class="card-body">
                    <form method="POST" action="{{ route('register') }}">
                        @csrf

                        <div class="form-group row">
                            <label for="name" class="col-md-4 col-form-label text-md-right">{{ __('Name') }}</label>

                            <div class="col-md-6">
                                <input id="name" type="text" class="form-control @error('name') is-invalid @enderror" name="name" value="{{ old('name') }}" required autocomplete="name" autofocus>

                                @error('name')
                                <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row">
                            <label for="username" class="col-md-4 col-form-label text-md-right">{{ __('Username') }}</label>

                            <div class="col-md-6">
                                <input id="name" type="text" class="form-control @error('username') is-invalid @enderror" name="username" value="{{ old('username') }}" required autocomplete="username" autofocus>

                                @error('username')
                                <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row">
                            <label for="email" class="col-md-4 col-form-label text-md-right">{{ __('E-Mail Address') }}</label>

                            <div class="col-md-6">
                                <input id="email" type="email" class="form-control @error('email') is-invalid @enderror" name="email" value="{{ old('email') }}" required autocomplete="email">

                                @error('email')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row">
                            <label for="password" class="col-md-4 col-form-label text-md-right">{{ __('Password') }}</label>

                            <div class="col-md-6">
                                <input id="password" type="password" class="form-control @error('password') is-invalid @enderror" name="password" required autocomplete="new-password">

                                @error('password')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row">
                            <label for="password-confirm" class="col-md-4 col-form-label text-md-right">{{ __('Confirm Password') }}</label>

                        <div class="form-group row mb-0">
                            <div class="col-md-6 offset-md-4">
                                <button type="submit" class="btn btn-primary">

                                </button>
                            </div>
                        </div>

                </div>
            </div>
        </div>
    </div>
</div>

Step 6 : Update Login Blade Template

Open login blade file from resources>views>auth folder. We are going to change some text.

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div class="card-header">{{ __('Login') }}</div>

                <div class="card-body">
                    <form method="POST" action="{{ route('login') }}">
                        @csrf

                        <div class="form-group row">
                            <label for="email" class="col-md-4 col-form-label text-md-right">{{ __('Username or Email') }}</label>

                            <div class="col-md-6">
                                <input id="email" type="text" class="form-control @error('email') is-invalid @enderror" name="email" value="{{ old('email') }}" required autocomplete="email" autofocus>

                                @error('email')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row">
                            <label for="password" class="col-md-4 col-form-label text-md-right">{{ __('Password') }}</label>

                            <div class="col-md-6">
                                <input id="password" type="password" class="form-control @error('password') is-invalid @enderror" name="password" required autocomplete="current-password">

                                @error('password')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row">
                            <div class="col-md-6 offset-md-4">
                                <div class="form-check">
                                    <input class="form-check-input" type="checkbox" name="remember" id="remember" {{ old('remember') ? 'checked' : '' }}>

                                    <label class="form-check-label" for="remember">
                                        {{ __('Remember Me') }}
                                    </label>
                                </div>
                            </div>

                                        <span class="text-danger"><strong>{{ $message }}</strong></span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row mb-0">
                            <div class="col-md-8 offset-md-4">

                                </button>

                                @if (Route::has('password.request'))
                                    <a class="btn btn-link" href="{{ route('password.request') }}">
                                        {{ __('Forgot Your Password?') }}
                                    </a>
