capture parameters pass to contribution form via URL

[mikesimaska]

CMS joomla 3.2
Civi 4.4.4

i have a front end to a donation form which is based on a calendar.  an action on the calendar will generate a URL for contribution form with a few params in the URL.  i'd like the contrib form to pick up those URL params and fill a few fields in the form.   i'd also like to pass along any checksum token that the calendar received and forward it to the contrib form.


what's the best approach to solving this problem?

I think you will have to implement buildForm hook and then have a logic that will fetch the params from url and use it for setting defaults.

ok -- this is the path im heading down.

seems like the easiest implementation would be via joomla plugin.  any reason NOT to head down that path?

I would recommend creating a civicrm extension, which is CMS agnostic and if you share this, someone else who wants something similar can use it too for other CMS.
