What are the steps to trigger onUserBeforeDelete and onUserAfterDelete events

1. Load the user object:

php
$userId = 123; // Replace with the actual user ID
$user = JFactory::getUser($userId);

2. Use the delete() method on the user object:

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

The delete() method internally triggers the onUserBeforeDelete and onUserAfterDelete events[1][2]. This ensures that any plugins listening for these events will be notified and can perform any necessary cleanup or additional actions.

Key points:

- The onUserBeforeDelete event is triggered before the user is deleted from the system[1].
- The onUserAfterDelete event is triggered after the user has been deleted[2].
- Using the User::delete() method is the recommended way to delete users as it handles related data and triggers the appropriate events[5].

By using this approach, you don't need to manually write SQL queries or handle the event triggering yourself. The Joomla User API takes care of it for you, ensuring that all related data and plugin events are handled correctly[3][5].

Remember to implement proper error handling and user existence checks in your actual code. This method is safe and consistent with Joomla's architecture, allowing plugins to respond to user deletion events as needed.
