Logging Last Login Information Using Laravel Events

Laravel's events provides a simple observer implementation, allowing you to subscribe and listen for various events that occur in your application. Events serve as a great way to decouple various aspects of your application, since a single event can have multiple listeners that do not depend on each other. So, we'll use Laravel Events to log each user's login information.

Registering Events

Edit the EventServiceProvider included in your Laravel application to register the event listener.

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Event;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        'Illuminate\Auth\Events\Login' => [
            'App\Listeners\LogSuccessfulLogin',
        ],
    ];

    /**
     * Register any events for your application.
     *
     * @return void
     */
    public function boot()
    {
        parent::boot();
        //
    }
}

Use the artisan event:generate command to generate the LogSuccessfulLogin listener.

Edit the LogSuccessfulLogin listener to add the event handling logic.

<?php

namespace App\Listeners;

use Illuminate\Http\Request;
use Illuminate\Auth\Events\Login;

class LogSuccessfulLogin
{
    /**
     * Create the event listener.
     *
     * @param  Request  $request
     * @return void
     */
    public function __construct(Request $request)
    {
        $this->request = $request;
    }

    /**
     * Handle the event.
     *
     * @param  Login  $event
     * @return void
     */
    public function handle(Login $event)
    {
        $user = $event->user;
        $user->last_login_at = date('Y-m-d H:i:s');
        $user->last_login_ip = $this->request->ip();
        $user->save();
    }
}

Update table structure

To be able to store the login information to database, we need to modify users table.

$ php artisan make:migration add_last_login_info_to_users_table --table=users

Add the last_login_at and the last_login_ip columns.

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class AddLastLoginInfoToUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::table('users', function (Blueprint $table) {
            $table->timestamp('last_login_at')->nullable()->after('remember_token');
            $table->string('last_login_ip')->nullable()->after('last_login_at');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::table('users', function (Blueprint $table) {
            $table->dropColumn(['last_login_at']);
            $table->dropColumn(['last_login_ip']);
        });
    }
}

Last step is do the migration:

$ php artisan migrate

In most cases, above code is enough. But how if we don't want to update "updated_at" field? It's very easy to solve with Query Builder. Just update the listener LogSuccessfulLogin with code below:

<?php

namespace App\Listeners;

use DB;
use Illuminate\Http\Request;
use Illuminate\Auth\Events\Login;

class LogSuccessfulLogin
{
    /**
     * Create the event listener.
     *
     * @param  Request  $request
     * @return void
     */
    public function __construct(Request $request)
    {
        $this->request = $request;
    }

    /**
     * Handle the event.
     *
     * @param  Login  $event
     * @return void
     */
    public function handle(Login $event)
    {
        $user = $event->user;
        DB::table('users')
            ->where('id', $user->id)
            ->update([
                'last_login_at'    => date('Y-m-d H:i:s'),
                'last_login_ip'    => $this->request->ip(),
            ]);
    }
}
