Answers.Text: Thanks Brad, that really helps. I feel like I'm close now. I can't seem to find how to get the user's id from that $user var which I believe to be of UserModel type? I've updated my question with the latest code.

Answers.Text: It doesn't :( I'm pretty sure it's not firing. The same code to cancel a membership is used elsewhere so I know that works. I'm not sure `$userId = $user->id;` is correct because I can't see an `id` mentioned in the UserModel documentation.

  (Asked by: username_0 on 2015-11-06)
  
  I'm currently building a plugin that uses a table that contains rows with an 'active' field set to 1.
  
  If an admin deletes a user from the system, I want to change this value to 0.
  
  I found an 'onUserDelete' event documented but can't work out where or how to use it.
  
  Any help would be greatly appreciated!
  
  EDIT UPDATED:
  
  I now have this code in the init() function of my plugin controller but deleting a user does not seem to fire the code:
  
  ```
      parent::init();
  
      craft()->on('users.onDeleteUser', function(Event $event) {
          $user = $event->params['user'];
  
          $userId = $user->id; // ???????
  
          $craft->memberships_membership->cancelMembershipById($userId);
      });
  
  ```
  
  Any ideas?

  From the [documentation](http://buildwithcraft.com/docs/plugins/hooks-and-events#events) on events, they follow this pattern:
  
  ```
  craft()->on('component.eventName', function(Event $event) {
      // ...
  });
  
  ```
  
  So in your example, it'd be something like this and you'd want to add it to your plugin's `init()` method in the main plugin class.
  
  ```
  public function init()
  {
      parent::init();
  
      craft()->on('users.onDeleteUser', function(Event $event) {
          $user = $event->params['user'];
          $userToTransferContentTo = $event->params['transferContentTo']
      });
  }
  
  ```
  
  The full list of available events and the parameters they have can be found [here](http://buildwithcraft.com/docs/plugins/events-reference).
