After reading documentation on paypals developers website for quite a while, I've come to stack. I'm a bit confused on how the whole API deal works, and I decided to take it simpler, find out if I even need to use anything more complex than buttons. So...
What I Need: Multiple options for digital goods (IE - 2 Posts for $5, 10 posts for $10)
I obviously could use a button to have them pay, but I need to be able to get a response to know which of the 2 (or more in the future) things they bought, so I can modify the database accordingly. Is this possible with something like https://www.x.com/community/ppx/wps
Or am I going to have to use the API? I installed Leon's Barretts' library for paypal in CodeIgniter: http://www.leonbarrett.com/code/paypal/
And I'm just completely unsure where to go from here, ideally I'd like the user to be able to pay with credit card w/o a paypal account, or pay with paypal with a paypal account.
Any thoughts to help me get going? Thanks guys!
