In this concise guide, we will illustrate the Laravel model updating event. If you're wondering how to utilize the updating event in Laravel, I'll provide a straightforward example with a solution. This article delves into the details of using the updating event in a Laravel model, offering a practical example of the Laravel updating event model.

In Laravel, model events offer a way to execute actions when a model is created, updated, deleted, and more. To illustrate the utilization of the updating event in a Laravel model, consider the following example. Suppose you have a Post model, and you wish to automatically trigger an event after updating a post record. This can be achieved using the updating event.

Laravel Model Updating Event Example

I'll provide you with a straightforward example of how to invoke the updating event from a model. Let's explore this simple illustration:

Create Post Model:

Create the Post model using the Artisan command:

php artisan make:model Post

In the generated Post model, define the updating event using the static::updating method. Here's an example:


namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;
class Post extends Model
    protected $fillable = ['title', 'content', 'slug'];
     * Write code on Method
     * @return response()
    protected static function boot()
        static::updating(function ($post) {
            info('Updating event call: '.$post);
            $post->slug = Str::slug($post->title);
        static::updated(function ($post) {
            info('Updated event call: '.$post);

Create Post Record:

In this example, when a new Post model is being updated, the updating event is triggered. We utilize a closure to generate a slug based on the title attribute, employing the Str::slug method from Laravel to create a URL-friendly slug from the title.

Now, when you create a new Post instance and save it, the updating event will automatically set the slug for you. Here's how you can create a new post:


namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Post;
class PostController extends Controller
     * Display a listing of the resource.
     * @return \Illuminate\Http\Response
    public function index(Request $request)
        $post = Post::find(1);
        $post->title = "This is Title".
        $post->body = "This is Content".

Now, execute the following controller code, and you will observe the corresponding logs for the calling of the creating event and created event, as shown below:


[2023-10-20 14:37:26] local.INFO: Updating event call: {"title":"This is Title","content":"This is a Content","slug":"this-is-testing","updated_at":"2023-10-20T14:37:26.000000Z","created_at":"2023-10-20T14:37:26.000000Z","id":1}
[2023-10-20 14:37:26] local.INFO: Updated event call: {"title":"This is Title","content":"This is a Content","slug":"this-is-title","updated_at":"2023-10-20T14:37:26.000000Z","created_at":"2023-10-20T14:37:26.000000Z","id":1}
