I'm looking for some implementation advice (using Joomla 3.4 and CiviCRM 4.6.9).
A client has a price set in place for membership that includes several standard membership levels, plus a few extra optional add-on services members can select. That works well for signups. But for renewals we'd like to be able to remind them what they paid the previous year, which they could then update or accept as given.
My first thoughts on how to do this:
Have a membership renewal page that pre-fills and pre-selects values based on the selections they made the previous year? I don't see a way to set up a membership contribution page in such a way that would do this (can't call up contribution info in a profile for the contribution page?). Could I do this with a hook (which one?)? Or would I need to use the API?
I know 4.6.9 has new invoicing capabilities, could that be used in some way to pre-set the contribution form selection? Or could I set up a process flow whereby we manually create the invoice based on values from last year, and send them an invoice that has a link to a contribution page where they can pay the amount due shown on the invoice?
Any advice would be appreciated -- anyone implemented anything like this before?
