CiviCRM Community Forums (archive)

Slightly different than a previous poster wrote about where he just needed numbers but no individual participant counts for report:

The client would like to have a participant be able to buy multiple tickets but not have to type in names and emails for each additional participant.

I modified AdditionalParticipants.php (under CRM>Event>Form>Registration) to default additional participants' names and email (using the primary/'paying' first participant's email and having checked the template choice to allow using the same email for all). The additional participants' first and last names are the primary one's names postfixed with _N where N is the participant number, e.g. if Ann Arbor buys tickets for herself and 2 others, the others are Ann_1 Arbor_1 and Ann_2 Arbor_@.
I wanted to add this option as a checkbox in the Event Template and I know this means updating the Event's DAO, adding the element in QuickForm and modifying the .tpl.
 I would contribute this code back, if it is acceptable and someone else wants it.  Is this the wrong approach?  I mean, I know I need to do more than implement a hook to add the element to the form, since this would mean a schema update. I can read documentation on how to package this, as a patch or whatever, but would like to hear whether anyone's interested, and if something I described is not the way to go.
