Create a Facebook Test App
After creating your Facebook app, you can connect it to your Laravel app by simply editing the
config/services.php file. Add this:
1 'facebook' => [
2 'client_id' => 'yourFacebookAppID',
3 'client_secret' => 'yourFacebookAppSecret',
4 'redirect' => 'http://yourLaravelAppURL/login/facebook/callback',
5 ],
Open database/migrations/timestamps_create_users_table.php file and update the up method:
1 public function up()
2 {
3 Schema::create('users', function (Blueprint $table) {
4 $table->increments('id');
5 $table->string('facebook_id')->unique();
6 $table->string('name');
7 $table->string('email')->unique();
8 $table->string('password', 60);
9 $table->rememberToken();
10 $table->timestamps();
11 });
12 }
php artisan make:migration update_users_table
Open the update_users_table file and update the code as follows:
1 <?php
2
3 use Illuminate\Database\Schema\Blueprint;
4 use Illuminate\Database\Migrations\Migration;
5
6 class UpdateUsersTable extends Migration
7 {
8 public function up()
9 {
10 if(Schema::hasColumn('users', 'facebook_id')) {
11
12 } else {
13 Schema::table('users', function ($table) {
14 $table->string('facebook_id')->unique();
15 });
16 }
17 }
18
19 public function down()
20 {
21 Schema::table('users', function ($table) {
22 $table->dropColumn('facebook_id');
23 });
24 }
25 }

1 protected $fillable = [
2 'name', 'email', 'password', 'facebook_id',
3 ];

The redirectToFacebook method:
1 public function redirectToFacebook()
2 {
3 return Socialite::with('facebook')->redirect();
4 }
The getFacebookCallback method:

2 {
3
4 $data = Socialite::with('facebook')->user();
5 $user = User::where('email', $data->email)->first();
6
7 if(!is_null($user)) {
8 Auth::login($user);
9 $user->name = $data->user['name'];
10 $user->facebook_id = $data->id;

11 $user->save();
12 } else {
13 $user = User::where('facebook_id', $data->id)->first();
14 if(is_null($user)){
15 // Create a new user
16 $user = new User();
17 $user->name = $data->user['name'];
18 $user->email = $data->email;
19 $user->facebook_id = $data->id;
20 $user->save();
21 }
22
23 Auth::login($user);
