Custom coded pro-form fields – Updating the users profile

Hi,

first off – great plugin. The combination of built in features and hooks that allow for custom coding are really providing a lot of flexibility. Currently, I have an authorize.net subscription form and I need for this form to update certain profile fields for logged in users (since I can not add buddypress xprofile fields to this pro form automatically). There are only a handful that I need, and I added them correctly so that these fields are updated for the user upon registration – the problem being I need this same function to occur when the user is simply upgrading the paid membership and already has an account. The hook I am using for registrations is this:

ws_plugin__s2member_during_configure_user_registration

Is there a similar hook for upgrading? Keep in mind I need to be able to access the post vars that are submitted from the pro checkout form. Not having access to those variables on member upgrade seems to be my main problem – I have tried other hooks that will be called after upgrade but they do not have access to the needed post vars.

Thanks
