I've got a website set up for a friend, and we are wanting to add a members section to the site. For this, I am wanting to utilize my existing page. I want to make payments through PayPal using PHP. I know already that this is NOT too complicated, I've already reviewed the code examples. I need someone to give me existing code, working, well commented, from clicking the registration link, to completion of payment, which i will then plug in my database commands into. Those with experience in this will be looked at first.
Working and well commented code in PHP.
