Laravel 5 Facebook Login Tutorial is the tutorial title today we will deep dive. I am going to show you how to Login users with Facebook and save them into your database using Laravel 5.4 I will guide you how to Integrate Facebook socialite login into your Laravel 5.4 application. So let us start.

Step 1: Make a project of Laravel Facebook Login.

Create a Laravel 5.4 project by typing following command.

composer create-project laravel/laravel socialLogin --prefer-dist

Go to that project and start the Laravel server by typing following command.

php artisan serve

Server starts at URL: http://localhost:8000

You need to configure your database in .env file.

Laravel 5.4 ships with by default two tables. So run the following command in your terminal after setting up with the database.

php artisan migrate

Two tables of users and password_reset tables and one migration table generated in MySQL Database

Step 2: Create a Laravel Authentication

Laravel Auth

Laravel provides us basic authentication. Laravel 5.4 makes implementing authentication very simple. In fact, almost everything is configured for you out of the box. We just need to fire one command in our terminal, and we are ready to go.

php artisan make:auth

You can see in the terminal that Authentication scaffolding generated successfully.

Now, if we switch to the routes >> web.php file then there is one added route, and also our view is configured automatically.

<?php // web.php Auth::routes();

Change to this URL: http://localhost:8000/login

You can see something like this and yes, don’t forget to start the server all the time by firing command php artisan serve.

Step 3: Download the laravel/socialite package for laravel 5 facebook integration

Laravel 5 Facebook Login Tutorial

The socialite is a package that makes building authentification with traditional social networks simple. So we are using this Laravel 5.4 specific package.

composer require laravel/socialite

Now, add the service provider to the config/app.php file.

<?php // app.php 'providers' => [ // Other service providers... Laravel\Socialite\SocialiteServiceProvider::class, ],

Moreover, also update an alias array

<?php // app.php 'Socialite' => Laravel\Socialite\Facades\Socialite::class,

Step 4: Create Facebook App To Get Tokens

Go to the Facebook’s developers portal by following URL: https://developers.facebook.com/

Login via your Facebook account. You will see something like this.

You can see in the image that there is Create App button. So click that button, and you will find one pop up window like this.

Here, I have put my name and email id in the popup and press button of Create App ID

You will see your dashboard like this.

In your dashboard, you can see your App ID

Now we need to select Facebook Login option from above image. So click that button, and you will redirect to Facebook Login Dashboard page. In this page, you can see your App ID and App Secret, which we need in our Laravel Application

App ID: xxxxxxxxx App Secret: xxxxxxx

Now, grab both of them and switch to your editor.

Navigate to the config >> services.php file and put one another services array by the following code.

Your App ID becomes your client_id, and App Secret becomes client_secret

<?php // services.php 'facebook' => [ 'client_id' => 'xxxxxxx', 'client_secret' => 'xxxxxxxx', 'redirect' => '', ],

Possible Error:

When you try to login via facebook and if you have not added the domain in your Facebook app. You will get following error.

Can’t load URL: The domain of this URL is not included in the app’s domains. To be able to load this URL, add all domains and sub-domains of your app to the App Domains field in your app settings.

Possible Solution:

You need to add the platform to your Facebook dashboard and in that type your project’s root URL like this.

Step 5: Generate a controller for Laravel Facebook Login

Now, we need to create one controller, which handles the Facebook Authentication routes.

php artisan make:controller SocialAuthFacebookController

We need to implement two methods in this controller, which are following.

1) redirect(): Redirect our users to the Facebook.

2) callback(): Handle callback from Facebook.

<?php // SocialAuthFacebookController.php namespace App\Http\Controllers; use Illuminate\Http\Request; use Socialite; class SocialAuthFacebookController extends Controller { /** * Create a redirect method to facebook api. * * @return void */ public function redirect() { return Socialite::driver('facebook')->redirect(); } /** * Return a callback method from facebook api. * * @return callback URL from facebook */ public function callback() { } }

Next step is going to the routes >> web.php file and register the routes.

<?php //web.php /* |-------------------------------------------------------------------------- | 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::get('/', function () { return view('welcome'); }); Auth::routes(); Route::get('/redirect', 'SocialAuthFacebookController@redirect'); Route::get('/callback', 'SocialAuthFacebookController@callback'); Route::get('/home', 'HomeController@index')->name('home');

Go to the config >> services.php file and update the Facebook keyed array with another key called redirect and put the value ‘http://localhost:8000/callback’

<?php // services.php 'facebook' => [ 'client_id' => 'xxxxxxx', 'client_secret' => 'xxxxxxx', 'redirect' => 'http://localhost:8000/callback', ],

Step 6: Create Login view file with blade templating engine.

Now we just need to add the link to our route redirect which will further redirect the user to the Facebook. So go to the resources >> views >> auth >> login.blade.php and add one link like Login with Facebook.

<!-- login.blade.php --> @extends('layouts.app') @section('content') <div class="container"> <div class="row"> <div class="col-md-8 col-md-offset-2"> <div class="panel panel-default"> <div class="panel-heading">Login</div> <div class="panel-body"> <form class="form-horizontal" method="POST" action="{{ route('login') }}"> {{ csrf_field() }} <div class="form-group{{ $errors->has('email') ? ' has-error' : '' }}"> <label for="email" class="col-md-4 control-label">E-Mail Address</label> <div class="col-md-6"> <input id="email" type="email" class="form-control" name="email" value="{{ old('email') }}" required autofocus> @if ($errors->has('email')) <span class="help-block"> <strong>{{ $errors->first('email') }}</strong> </span> @endif </div> </div> <div class="form-group{{ $errors->has('password') ? ' has-error' : '' }}"> <label for="password" class="col-md-4 control-label">Password</label> <div class="col-md-6"> <input id="password" type="password" class="form-control" name="password" required> @if ($errors->has('password')) <span class="help-block"> <strong>{{ $errors->first('password') }}</strong> </span> @endif </div> </div> <div class="form-group"> <div class="col-md-6 col-md-offset-4"> <div class="checkbox"> <label> <input type="checkbox" name="remember" {{ old('remember') ? 'checked' : '' }}> Remember Me </label> </div> </div> </div> <div class="form-group"> <div class="col-md-8 col-md-offset-4"> <button type="submit" class="btn btn-primary"> Login </button> <a class="btn btn-link" href="{{ route('password.request') }}"> Forgot Your Password? </a> </div> </div> <br /> <p style="margin-left:265px">OR</p> <br /> <div class="form-group"> <div class="col-md-8 col-md-offset-4"> <a href="{{url('/redirect')}}" class="btn btn-primary">Login with Facebook</a> </div> </div> </form> </div> </div> </div> </div> </div> @endsection

Now, if you have not started the server, then launch the server and go the following URL

http://localhost:8000/login

Try to login via Facebook and if everything sets up correctly.

Possible Error:

cURL error 60: SSL certificate problem: unable to get local issuer certificate

Possible Solution:

Assuming On Windows

XAMPP server

Similar to another environment – download and extract for cacert.pem here (a clean file format/data)

https://curl.haxx.se/docs/caextract.html put it here

C:\xampp\php\extras\ssl\cacert.pem in your php.ini put this line in this section (“c:\xampp\php\php.ini”):

;;;;;;;;;;;;;;;;;;;; ; php . ini Options ; ;;;;;;;;;;;;;;;;;;;; curl . cainfo = "C:\xampp\php\extras\ssl\cacert.pem"

Moreover, finally, restart your server.

Step 7: Make one model for Social Account

Now, when you try to Log in with Facebook, you will redirect to nothing, and in your URL, you can see the callback with some code in it. So let’s fix that.

Now, we are integrating our Facebook user in our Laravel application. Create one model as well as one migration in our app.

php artisan make:model SocialFacebookAccount -m

Now, add the following code in create_social_facebook_accounts_table.php file. I am putting my final file in here.

<?php // create_social_facebook_accounts.php use Illuminate\Support\Facades\Schema; use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class CreateSocialFacebookAccountsTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::create('social_facebook_accounts', function (Blueprint $table) { $table->integer('user_id'); $table->string('provider_user_id'); $table->string('provider'); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::dropIfExists('social_facebook_accounts'); } }

Run the following command if you have migrated previous tables.

php artisan migrate:refresh

Alternatively, else, if this is your first-time migration then apply following command.

php artisan migrate

Step 8: Give relations to SocialFacebookAccount model.

The column provider_user_id is Facebook’s user id, and in provider this case, will always be Facebook

Add relations and fillable to the SocialFacebookAccount model.

<?php // SocialFacebookAccount.php namespace App; use Illuminate\Database\Eloquent\Model; class SocialFacebookAccount extends Model { protected $fillable = ['user_id', 'provider_user_id', 'provider']; public function user() { return $this->belongsTo(User::class); } }

Next step would be some handling service that will try to register the user or login if the account already exists. Create folder app/Services . Laravel 5.4 has not any Services folder in app directory so create a directory first and put following content in that SocialFacebookAccountService.php file. So our full directory structure would look like this.

app >> Services >> SocialFacebookAccountService.php

<?php namespace App\Services; use App\SocialFacebookAccount; use App\User; use Laravel\Socialite\Contracts\User as ProviderUser; class SocialFacebookAccountService { public function createOrGetUser(ProviderUser $providerUser) { $account = SocialFacebookAccount::whereProvider('facebook') ->whereProviderUserId($providerUser->getId()) ->first(); if ($account) { return $account->user; } else { $account = new SocialFacebookAccount([ 'provider_user_id' => $providerUser->getId(), 'provider' => 'facebook' ]); $user = User::whereEmail($providerUser->getEmail())->first(); if (!$user) { $user = User::create([ 'email' => $providerUser->getEmail(), 'name' => $providerUser->getName(), 'password' => md5(rand(1,10000)), ]); } $account->user()->associate($user); $account->save(); return $user; } } }

It will try to find provider’s account in the system and if it is not present it will create a new user. This method will also try to associate the social account with the email address in case that user already has an account.

Now everything is ready to handle Facebook’s callback to our app.

Step 9: Update callback function.

The last step is to update the SocialAuthFacebookController’s callback() function.

<?php // SocialAuthFacebookController.php namespace App\Http\Controllers; use Illuminate\Http\Request; use Socialite; use App\Services\SocialFacebookAccountService; class SocialAuthFacebookController extends Controller { /** * Create a redirect method to facebook api. * * @return void */ public function redirect() { return Socialite::driver('facebook')->redirect(); } /** * Return a callback method from facebook api. * * @return callback URL from facebook */ public function callback( SocialFacebookAccountService $service ) { $user = $service->createOrGetUser(Socialite::driver('facebook')->user()); auth()->login($user); return redirect()->to('/home'); } }

All the coding is now finally complete. Go to the login URL of our application.

http://localhost:8000/login

Now, Login with Facebook and you will redirect to the home page and the data has been saved in the database.

Step 10: Make live your Laravel 5 Facebook Integration with the public.

Right now your application is in development mode, so when you try to login with another Facebook username and password then It will not work.

For that, you need to do following the steps.

STEP 1:

Log in to Facebook Developer -> Your App

In Settings -> Basic -> Contact Email. (Give any email)

STEP 2:

And in ‘App Review‘ Tab: change

Do you want to make this app and all its live features available to the general public? Yes

And your app will be live now.

Now, you will be able to log in as any Facebook user.

Steps to use Github code

Clone the repo in your local. Go to root of the project and run command “composer update“ Edit .env file and use your MySQL database credentials. Configure developers facebook account get client_id and client_secret and also put your Web URL. Run the command “php artisan migrate“ Now, we need to bootstrap Laravel server so run “php artisan serve“ If now go to this URL: http://localhost:8000/login
