Currently we use a different template for confirmation / receipt email when a participant is registered offline (contact -> view -> events tab -> New Event Registration uses CRM/Contribute/Form/ReceiptMessageOffline.tpl). This means that the participant email is missing the following:
- event details like start and end date, location, phone and email contact info for the event
- event fee level OR price set information
We should modify Event/Form/Participant.php so it can also use CRM/Event/Form/Registration/ReceiptMessage.tpl - and hence give the participant all the relevant info.
NOTE: We've had a few people report that Price Set info is NOT being included for ONLINE Registration confirmations if the confirmation is sent when a Pending (pay later ) event's contribution record is updated to Completed. Please check this and fix if needed (Lobo thinks the price set id may be need to be retrieved explicitly since in the non-pay-later flow we get it from the session.)
