Where do I put my Affiliate Program code?

[zedseven]

Hi there,

I have just started a forum. It has a paid subscription component. I want to run an affiliate program. I need to put a piece of code somewhere that is activated when someone successfully upgrades to the paid subscription.

Can someone point me in the right direction of where to put this code? It needs to be upon successful sign up. It can be either PHP or javascript code.

Thanks for your help.

This is an old post with no replies. Does that mean that this can't be done? I have a similar question and just curious where the snipet might go. Anyone? Please!
