AJAX user registration and JSON returned

Question

I am using business logic plugin to tap into save user event and create some profile field values.

public function init(){
    parent::init();

    craft()->on('users.saveUser', function(Event $event) {

    }
}

On save user returns a success object. I want to return more user profile data to the page on success.

In the save User function I have tried:

 if (craft()->request->isAjaxRequest())
 {
     $return = array(
         'success' => true,
         'errorCode' => 1,
         'uid' => $user->id,
         'urn' => $URN
     );

     return json_encode($return);
 }

but I still get the usual response of success and user id. How do i get a thank you 'page' into the process so I can feedback to the user?

Answer 1

Instead of listening to the onSaveUser event, I'd update my user save form on the front-end to point to a controller's action in my plugin.

You can run similar logic to what Craft's UsersController->actionSaveUser() is doing and return any custom JSON encoded data you want back to your template.
