iDevAffiliate plugin

Hello,

i make some test to make working iDevAffiliate with Membership Pro.
iDev have a plugin for MP. As i understand, this plugin make 2 things :

1. it store the IP address and the order ID in a database additional.
2. it get the different data and compile it. After that, it send the data in an url, with the IP address, product name, etc etc.
That make the commission in my iDev admin panel.

All of that work fine, but... I want more control on my commissions. Actually, with iDevAffiliate, you cant define easily different percentage of commission amount depending of different plan.

But, i can override the data passed to the url to force the amount i want to commission.
So for do that, i want use the PHP plugin of Membership pro.
Normally, i can perform the 2 thing that the actual idev plugin do.

So i have tested that in a dev site, and i cant make it work. Honnestly, i thing i dont put the code correctly in the 2 php filed of Membership Pro.
So my question is can you please take a look at the plugin code and tell me how i have to cut it and past in the 2 Membership pro field ?

Because if i can make it work, i could make commission by plan, and dont use the iDev plugin anymore.

I attach the php code of the plugin in zip because i cant write it here (firewall).

Regards,
Frédéric
