Hi,

So I'm using hook_civicrm_post to make certain mods to objects in CiviCRM and CiviEvent and CiviContribute.  I have a value I'm trying to save in the Participant after an event is registered for.  It is a custom field.  And I can see that it's "custom_27".  But when I'm doing a civicrm_participant_update(), setting just the id and the 'custom_27', doesn't do the trick from what I can tell.  

I looked at the hook_civicrm_buildForm, but I realize that the form is for the Event, not for the Participant, so I can't inject information using this technique, right?  http://wiki.civicrm.org/confluence/display/CRMDOC/Update+custom+fields+in+contributions+and+events+by+passing+variables+in+a+URL

So how do I make this happen?

And if it's not implemented, how can I implement setting the custom field on the post?

Thanks a ton!!!
