Hey,

On which process page you try to implement dynamic button? Why? I think you try to same on any product listing page for clicking on button that product will add into current cart session, If yes than you can achieve same with using php/ajax and creating new table like cart_master. And clicking on that button you have write code to that product id goes into cart_master table along with userid.

I hope this will help you!
