CI transaction on functions

[eluser]Raymondddd[/eluser]
Hi guys,

Currently creating a cart system for a company with CI. In the last step of the checkout i call a lot of functions like; create user, create order, order detail and more.

I need to check if any of these function went ok, and if not; use a transaction.

I've read this: http://ellislab.com/codeigniter/user-gui...tions.html but this will only work if you create a list of DB queries between the trans_start and trans_complete.

Is there something like a transaction possibility using functions?

Looking forward to your reply.

Raymond
