Recording last login information using Laravel events 8.0

 Recording last login information using Laravel events

Laravel’s events provide a simple observer implementation, allowing you to listen for various events that occur in your application. Laravel raises several events throughout the authentication process. This example shows how to attach a listener for the Illuminate\Auth\Events\Login event and store when a user has last logged in and from what IP address.

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.

$ php artisan event:generate

Events and listeners generated successfully!

Edit the LogSuccessfulLogin listener to add the event handling logic.

<?php

namespace App\Listeners;

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

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();
    }
}

Database migrations

The above implementation records the last login information in two columns on the users table. Use the artisan make:migration command to create the migrations for each of the columns that will be added to the users table.

$ php artisan make:migration add_last_login_at_to_users_table --table=users
Created Migration: 2017_03_07_173328_add_last_login_at_to_users_table
$ php artisan make:migration add_last_login_ip_to_users_table --table=users
Created Migration: 2017_03_07_173333_add_last_login_ip_to_users_table

Edit the migrations to 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 AddLastLoginAtToUsersTable 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');
        });
    }

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

<?php

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

class AddLastLoginIpToUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::table('users', function (Blueprint $table) {
            $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_ip']);
        });
    }
}

Use the artisan migrate command to run the migrations.

$ php artisan migrate
