Laravel 9.18 Released image

The Laravel team released 9.18 jam-packed with amazing features and quality-of-life improvements. Let's look at the high-level details of the standout features now available in Laravel 9!

Improve file attachments for mail and notifications

Tim MacDonald contributed attachable objects, which you can use to implement attachments with models:

namespace App\Models;
use Illuminate\Contracts\Mail\Attachable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Mail\Attachment;
class Photo extends Model implements Attachable
* Get the attachable representation of the model.
* @return \Illuminate\Mail\Attachment
public function toMailAttachment()
return Attachment::fromPath('/path/to/file');

When building an email message, you can pass an instance of the model via the attach() method:

public function build()
return $this->view('photos.resized')

See the new attachable objects documentation for complete details on this beneficial feature!

Invokable validation classes

Tim MacDonald contributed invokable validation classes:

This PR aims to introduce a new class based validation implementation that mixes the brevity + simplicity of Closure based rules with the shareable, extendable, and chainable nature of class based rules by introducing an Invokable validation rule.

Here's an example implementation from Pull Request #42689:

class InvokableQuantity implements InvokableRule
public function __invoke($attribute, $value, $fail)
if (! is_array($value)) {
return $fail('validation.quantity.must_be_an_object')->translate();
if (! array_key_exists('magnitude', $value)) {
if (! array_key_exists('units', $value)) {

Predis 2.0

Dries Vints contributed support for Predis 2.0. Predis 2.0.0 is a maintenance release, so nothing should break.

Define nested "with" relations via a nested array

Tim MacDonald contributed a way to define nested eager loading relationships via a nested array:

// Using dot notation
$books = Book::with('author.contacts')->get();
// Nested array
$books = Book::with([
'author' => [

Add host methods to the Illuminate Request object

Pull Request #42797 provides three convenience methods on the Illuminate Request instance to access underlying Symphony methods:

$request->host(); // getHost()
$request->httpHost(); // getHttpHost()
$request->schemeAndHttpHost(); // getSchemeAndHttpHost()

Invokable validation rules can push messages to nested attributes

Tim MacDonald contributed the ability for invokable validation rules to push errors to nested and other attributes:

class UserRule implements InvokableRule
public function __invoke($attribute, $value, $fail)
if (! is_array($attribute) || array_is_list($attribute)) {
return $fail('Must be an object.'); // apply to $attribute
if (! array_key_exists('name', $attribute)) {
return $fail("{$attribute}.name", 'Is required.'); // apply to nested attribute
/* ... */

Given the above implementation, here's a usage example:

'user_1' => ['xxxx'],
'user_2' => ['age' => 23],
'user_1' => [new UserRule()],
'user_2' => [new UserRule()],
// errors...
'user_1' => ['Must be an object.'],
'' => ['Is required.'],

Introduce fake() helper

Tim MacDonald contributed a global fake() helper function that allows you to easily access a singleton faker instance. Using this helper is helpful when prototyping, testing, and generating factory and seed data:

@for($i = 0; $i < 10; $i++)
<dd>{{ fake()->name() }}</dd>
<dd>{{ fake()->phoneNumber() }}</dd>

Here's an example of locale-specific faker usage:

fake()->name() // config('app.faker_locale') ?? 'en_US'
fake('en_AU')->name() // en_AU

Cumulative query duration limit callback

Tim MacDonald contributed a callback handler after a cumulative query limit duration:

DB::handleExceedingCumulativeQueryDuration(Interval::seconds(5), function (Connection $connection) {
Log::warning("Database queries exceeded 5 seconds on {$connection->getName()}");

To learn more about this feature, check out the official documentation for cumulative query time. Also, check out Pull Request #42744 for implementation details and discussion around this feature.
