Provide code delete users via Joomla REST API

Step-by-Step Guide

1. Load the User Model: First, you need to load the user model to access the delete function.

2. Delete the User: Use the `delete` method provided by the user model to remove the user by their ID.

Example Code

Here is a sample PHP code snippet that demonstrates how to delete a user using Joomla's User API:

php
// Load the necessary Joomla framework
defined('_JEXEC') or die;

// Import the user model
jimport('joomla.user.helper');
jimport('joomla.application.component.model');

// Get the user ID to delete
$userId = 123; // Replace with the actual user ID

// Load the user object
$user = JFactory::getUser($userId);

// Check if the user exists
if (!$user->id) {
    echo "User not found.";
    return;
}

// Delete the user
if (!$user->delete()) {
    echo "Failed to delete user.";
} else {
    echo "User deleted successfully.";
}

Explanation

1. Load Joomla Framework: Ensure the Joomla framework is loaded with `defined('_JEXEC') or die;`.

2. Import User Model: Import the necessary Joomla classes using `jimport`.

3. Get User ID: Replace `$userId = 123;` with the actual user ID you want to delete.

4. Load User Object: Use `JFactory::getUser($userId)` to load the user object.

5. Check User Existence: Verify if the user exists by checking `$user->id`.

6. Delete User: Call the `delete` method on the user object to delete the user. Handle success or failure accordingly.

Additional Considerations

- Triggering Plugin Events: The `delete` method triggers `onUserBeforeDelete` and `onUserAfterDelete` events, ensuring that any related data managed by plugins is also deleted[1][2][4].
- Error Handling: Implement proper error handling to manage cases where the user does not exist or the deletion fails.

This approach ensures that all related data and plugin events are handled correctly, avoiding the need to manually write SQL queries for each related table.
