How to programatically create a user in Joomla 4.x

Question

In Joomla 3.x I used to create a user object with

$user = clone(JFactory::getUser());

(which I would then bind to an array of data, and then call save() on it), but JFactory::getUser() is deprecated now.

What is the new way of creating a new blank user object?

Answer 1

Factory::getContainer()->get(UserFactoryInterface::class)->loadUserById(0);

Joomla uses this line for creating an empty User object around line 287 in ..\libraries\src\User\User.php

// If the $id is zero, just return an empty User.
// Note: don't cache this user because it'll have a new ID on save!
if ($id === 0) {
    return Factory::getContainer()->get(UserFactoryInterface::class)->loadUserById($id);
}

You would need to add the appropriate statements for Factory and UserFactoryInterface in your code to get the object from the container by adding 'Use' statements, or use the following:

$user = \Joomla\CMS\Factory::getContainer()->get('user.factory')->loadUserById(0);
