CakePHP ORM in your app

We all know that CakePHP is a Full Stack framework, but you may not know that you can pick some of the components and use it in your app when you need. The ORM is not the only one available - you could also have filesystem, validation, utility, core, collection, database, cache, event, form, log, datasource, console and i18n. In this article, we are going to show how to use the ORM component in your slim framework app. You can find the component at: https://github.com/cakephp/?q=read&type=&language=

Why should we use the componentes

You may be asking why to use as component instead of using the framework as it is, and one of the reasons would be that you already have an application, perhaps using slim framework, and now you need to retrieve data from database. This would be a good moment to use a lib to help you, and here is where cakephp/orm comes in handy.

With the componentes you can now solve things with your knowledge in CakePHP, even when your application was not built with CakePHP.

Setting up cakephp/orm in a slim application

The code used in this article can be found at: https://github.com/CakeDC/slim-cakephp4-packages

We could use the package in any PHP application, but for this article we are going to use a slim application skeleton https://github.com/slimphp/Slim-Skeleton. In this app we’re going to change the routes /users and /users/[id] to fetch data from database instead of in-memory data.

Install the package with composer

We are going to install the version 4.0 of the ORM package:

composer require cakephp/orm:~4.0

Update config

The app uses the file app/settings.php to set up the main configs, so we need to add a config for database and set cakephp’s App.namespace config.

First: add this line after the use declaration. Don’t worry about this config now. We’re setting this to avoid error with PHP 7.4.

Configure::write('App.namespace', 'App');

Then add your database config key inside settings array - in this case we’re using mysql database from a docker service:

'database' => [

'className' => \Cake\Database\Connection::class,

'driver' => \Cake\Database\Driver\Mysql::class,

'database' => 'my_db',

'username' => 'root',

'password' => 'secret',

'host' => 'mysql',

]

See https://github.com/CakeDC/slim-cakephp4-packages/blob/main/app/settings.php

Add TableLocator to app dependencies

The app uses the file app/dependencies.php to configure the container of dependencies, and this is a good place for us to define TableLocator as dependency since we normally would use it

In my places. Let’s add this inside $containerBuilder->addDefinitions:

\Cake\ORM\Locator\TableLocator::class => function(ContainerInterface $c) {

$settings = $c->get('settings');

\Cake\Datasource\ConnectionManager::setConfig('default', $settings['database']);

return new \Cake\ORM\Locator\TableLocator();

}

See https://github.com/CakeDC/slim-cakephp4-packages/blob/main/app/dependencies.php

This service gets the settings we defined before,sets the configuration to CakePHP, and returns an instance of TableLocator.

We could use this service in any route action with:

$locator = $this->get(\Cake\ORM\Locator\TableLocator::class);

$users = $locator->get('Users')->find()->all()->toArray();

But for this app it will make sense to use the TableLocator in a custom persistence class.

Using the ORM to fetch data

Now, we are finally going to replace the current way of retrieving data to be able to use CakePHP OR. Since our idea is to have a minimum impact in the app, the best way for this app is to replace the current UserRepository. Keep in mind that you could use the following steps with any other class you have.

Create a new persistence class DatabaseUserRepository:

Create the class at src/Infrastructure/Persistence/User/DatabaseUserRepository.php

Define a constructor method with tableLocator parameter

public function __construct(\Cake\ORM\Locator\TableLocator $tableLocator)

{

$this->tableLocator = $tableLocator;

}

Now we can use the tableLocator to fetch data:

$this->tableLocator->get('Users')->find()->all();

$this->tableLocator->get('Users')->get(10);

////

To make the app work correctly, we need to add the required method findAll and findUserOfId

See: https://github.com/CakeDC/slim-cakephp4-packages/blob/main/src/Infrastructure/Persistence/User/DatabaseUserRepository.php

Now that the repository persistence class was created, we need to connect using dependency injection. Update the UserRepository::class entry in repositories with:

UserRepository::class => \DI\autowire(\App\Infrastructure\Persistence\User\DatabaseUserRepository::class),

https://github.com/CakeDC/slim-cakephp4-packages/blob/main/app/repositories.php

That’s it! Now we can access /users and see the users stored in our database.

I hope you’ve found this information to be helpful! Let us know!

Goodbye to 2025!

Well bakers… another advent calendar is coming to an end. I hope you enjoyed all of the topics covered each day. We are also closing the year with so much gratitude. 2025 was the 20th year of CakePHP, can you believe it? We had an amazing year with our team, the community and the CakePHP core. It was great connecting with those who attended CakeFest in Madrid, and we hope to have the opportunity to see more of you in 2026. I cannot let the year end without getting a little sentimental. There is no better way to say it… THANK YOU. Thank you to the team who worked so hard, the core team that keeps pumping out releases, and most of all … thank you to our clients that trust us with their projects. CakeDC is successful because of the strong relationships we build with our network, and we hope to continue working with all of you for many years. There are a lot of great things still to come in year 21! Could 2026 will be bringing us CakePHP 6?! Considering 2 is rhe legal drinking age in the US, maybe CakePHP 6 should be beer cake? Delicious. Stay tuned to find out. Before I go, I am leaving you with something special. A note from Larry! As we close out this year, I just want to say thank you from the bottom of my heart. Twenty years ago, CakePHP started as a simple idea shared by a few of us who wanted to make building on the web easier and more enjoyable. Seeing how far it has come, and more importantly, seeing how many lives and careers it has impacted, is something I never take for granted. I am deeply grateful for our team, the core contributors, the community, and our clients who continue to believe in what we do. You are the reason CakePHP and CakeDC are still here, still growing, and still relevant after two decades. Here is to what we have built together, and to what is still ahead. Thank you for being part of this journey. Larry

Pagination of multiple queries in CakePHP

A less typical use case for pagination in an appication is the need to paginate multiples queries. In CakePHP you can achieve this with pagination scopes.

Users list

Lest use as an example a simple users list.

// src/Controller/UsersController.php

class UsersController extends AppController
{
    protected array $paginate = [
        'limit' => 25,
    ];

    public function index()
    {
        // Default model pagination
        $this->set('users', $this->paginate($this->Users));
    }
}

// templates/Users/index.php

<h2><?= __('Users list') ?>/h2>
<table>
    <thead>
        <tr>
            <th><?= $this->Paginator->sort('name', __('Name')) ?></th>
            <th><?= $this->Paginator->sort('email', __('Email')) ?></th>
            <th><?= $this->Paginator->sort('active', __('Active')) ?></th>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($users as $user): ?>
        <tr>
            <td><?= h($user->name) ?></td>
            <td><?= h($user->email) ?></td>
            <td><?= $user->active ? 'Yes' : 'No' ?></td>
        </tr>
        <?php endforeach; ?>
    </tbody>
</table>
<?= $this->Paginator->counter() ?>
<?= $this->Paginator->prev('« Previous') ?>
<?= $this->Paginator->numbers() ?>
<?= $this->Paginator->next('Next »') ?>

Pagination of multiple queries

Now, we want to display two paginated tables, one with the active users and the other with the inactive ones.

// src/Controller/UsersController.php

class UsersController extends AppController
{
    protected array $paginate = [
        'Users' => [
            'scope' => 'active_users',
            'limit' => 25,
        ],
        'InactiveUsers' => [
            'scope' => 'inactive_users',
            'limit' => 10,
        ],
    ];

    public function index()
    {
        $activeUsers = $this->paginate(
            $this->Users->find()->where(['active' => true]),
            [scope: 'active_users']
        );

        // Load an additional table object with the custom alias set in the paginate property
        $inactiveUsersTable = $this->fetchTable('InactiveUsers', [
            'className' => \App\Model\Table\UsersTable::class,
            'table' => 'users',
            'entityClass' => 'App\Model\Entity\User',
        ]);
        $inactiveUsers = $this->paginate(
            $inactiveUsersTable->find()->where(['active' => false]),
            [scope: 'inactive_users']
        );

        $this->set(compact('users', 'inactiveUsers'));
    }
}

// templates/Users/index.php

<?php
// call `setPaginated` first with the results to be displayed next, so the paginator use the correct scope for the links
$this->Paginator->setPaginated($users);
?>
<h2><?= __('Active Users') ?>/h2>
<table>
    <thead>
        <tr>
            <th><?= $this->Paginator->sort('name', __('Name')) ?></th>
            <th><?= $this->Paginator->sort('email', __('Email')) ?></th>
            <th><?= $this->Paginator->sort('active', __('Active')) ?></th>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($users as $user): ?>
        <tr>
            <td><?= h($user->name) ?></td>
            <td><?= h($user->email) ?></td>
            <td><?= $user->active ? 'Yes' : 'No' ?></td>
        </tr>
        <?php endforeach; ?>
    </tbody>
</table>
<?= $this->Paginator->counter() ?>
<?= $this->Paginator->prev('« Previous') ?>
<?= $this->Paginator->numbers() ?>
<?= $this->Paginator->next('Next »') ?>

<?php
// call `setPaginated` first with the results to be displayed next, so the paginator use the correct scope for the links
$this->Paginator->setPaginated($inactiveUsers);
?>
<h2><?= __('Inactive Users') ?>/h2>
<table>
    <thead>
        <tr>
            <th><?= $this->Paginator->sort('name', __('Name')) ?></th>
            <th><?= $this->Paginator->sort('email', __('Email')) ?></th>
            <th><?= $this->Paginator->sort('active', __('Active')) ?></th>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($inactiveUsers as $inactiveUser): ?>
        <tr>
            <td><?= h($inactiveUser->name) ?></td>
            <td><?= h($inactiveUser->email) ?></td>
            <td><?= $inactiveUser->active ? 'Yes' : 'No' ?></td>
        </tr>
        <?php endforeach; ?>
    </tbody>
</table>
<?= $this->Paginator->counter() ?>
<?= $this->Paginator->prev('« Previous') ?>
<?= $this->Paginator->numbers() ?>
<?= $this->Paginator->next('Next »') ?>

And with this you have two paginated tables in the same request.

Clean DI in CakePHP 5.3: Say Goodbye to fetchTable()

This article is part of the CakeDC Advent Calendar 2025 (December 23rd, 2025)

Introduction: The Death of the "Hidden" Dependency

For years, accessing data in CakePHP meant "grabbing" it from the global state. Whether using TableRegistry::getTableLocator()->get() or the LocatorAwareTrait’s $this->fetchTable(), your classes reached out to a locator to find what they needed. While convenient, this created hidden dependencies. A class constructor might look empty, despite the class being secretly reliant on multiple database tables. This made unit testing cumbersome, forcing you to stub the global TableLocator just to inject a mock. CakePHP 5.3 changes the game with Inversion of Control. With the framework currently in its Release Candidate (RC) stage and a stable release expected soon, now is the perfect time to explore these architectural improvements. By using the new TableContainer as a delegate for your PSR-11 container, tables can now be automatically injected directly into your constructors. This shift to explicit dependencies makes your code cleaner, fully type-hinted, and ready for modern testing standards. The Old Way (Hidden Dependency):

public function execute() {
    $users = $this->fetchTable('Users'); // Where did this come from?
}

The 5.3 Way (Explicit Dependency):

public function __construct(protected UsersTable $users) {} 

public function execute() {
    $this->users->find(); // Explicit and testable.
}

Enabling the Delegate

Open src/Application.php and update the services() method by delegating table resolution to the TableContainer.

// src/Application.php
use Cake\ORM\TableContainer;

public function services(ContainerInterface $container): void
{
    // Register the TableContainer as a delegate
    $container->delegate(new TableContainer());
}

How it works under the hood

When you type-hint a class ending in Table (e.g., UsersTable), the main PSR-11 container doesn't initially know how to instantiate it. Because you've registered a delegate, it passes the request to the TableContainer, which then:

Validates: It verifies the class name and ensures it is a subclass of \Cake\ORM\Table.
Locates: It uses the TableLocator to fetch the correct instance (handling all the usual CakePHP ORM configuration behind the scenes).
Resolves: It returns the fully configured Table object back to the main container to be injected.

Note: The naming convention is strict. The TableContainer specifically looks for the Table suffix. If you have a custom class that extends the base Table class but is named UsersRepository, the delegate will skip it, and the container will fail to resolve the dependency.

Practical Example: Cleaner Services

Now, your domain services no longer need to know about the LocatorAwareTrait. They simply ask for what they need.

namespace App\Service;

use App\Model\Table\UsersTable;

class UserManagerService
{
    // No more TableRegistry::get() or $this->fetchTable()
    public function __construct(
        protected UsersTable $users
    ) {}

    public function activateUser(int $id): void
    {
        $user = $this->users->get($id);
        // ... logic
    }
}

Next, open src/Application.php and update the services() method by delegating table resolution to the TableContainer.

// src/Application.php
use App\Model\Table\UsersTable;
use App\Service\UserManagerService;
use Cake\ORM\TableContainer;

public function services(ContainerInterface $container): void
{
    // Register the TableContainer as a delegate
    $container->delegate(new TableContainer());

    // Register your service with the table as constructor argument  
    $container  
        ->add(UserManagerService::class)  
        ->addArgument(UsersTable::class);
}

Why this is a game changer for Testing

Because the table is injected via the constructor, you can now swap it for a mock effortlessly in your test suite without touching the global state of the application.

$mockUsers = $this->createMock(UsersTable::class);
$service = new UserManagerService($mockUsers); // Pure injection!

Conclusion: Small Change, Big Impact

At first glance, adding a single line to your Application::services() method might seem like a minor update. However, TableContainer represents a significant shift in how we approach CakePHP architecture. By delegating table resolution to the container, we gain:

True Type-Safety: Your IDE and static analysis tools now recognize the exact Table class being used. This is a massive win for PHPStan users—no more "Call to an undefined method" errors or messy @var docblock workarounds just to prove to your CI that a method exists.
Zero-Effort Mocking: Testing a service no longer requires manipulating the global TableRegistry state. Simply pass a mock object into the constructor and move on.
Standardization: Your CakePHP code now aligns with modern PHP practices found in any PSR-compliant ecosystem, making your application more maintainable and easier for new developers to understand.

If you plan to upgrade to CakePHP 5.3 upon its release, this is one of the easiest wins for your codebase. It’s time to stop fetching your tables and start receiving them. This article is part of the CakeDC Advent Calendar 2025 (December 23rd, 2025)
