Non deprecated method in Joomla! 4 to load user by userid

Question

I'm looking for an extension for Joomla! 4.0 to replace a deprecated method which was used to load an user by userid. The method used actually is:

$user = Factory::getUser($userid);

The issue is that in the error log it is recommended to use Factory::getApplication()->getIdentity() instead, but this method doesn't accept params! The other method that I found is Factory::getApplication()->loadIdentity(), but this one accepts User object as its parameter.

So which is the non-deprecated method to load a user object by passing userid?

Answer 1

Use Joomla\CMS\User\UserFactory. You can get it from the service container:

use Joomla\CMS\User\UserFactoryInterface;

$userFactory = $container->get(UserFactoryInterface::class);

Or using alias:

$userFactory = $container->get('user.factory');

Where $container is the container. If you're doing this inside service provider file (services/provider.php), it's already defined. Otherwise, if using container as service locator inside your classes, get it from main factory:

$container = \Joomla\CMS\Factory::getContainer();

To create a user instance:

$user = $userFactory->loadUserById($id);

I've used @Sharky's (thanks!) solution like:

use Joomla\CMS\User\UserFactoryInterface;

$user = Factory::getContainer()->get(UserFactoryInterface::class)->loadUserById($userid);
