How to integrate paypal with codeigniter?

I am trying to integrate PayPal payment with my codeigniter project. My project is dedicated to a dating site in which two different users interact with each other. Therefore, I sell plans based on which users will be granted access to send messages to others during this period of time. To do this, I developed a very simple page containing switches for choosing from different plans. These are the following plans.

  • one month ( $2)
  • Two months ( $4)
  • Three months ( $6)
  • Four months ( $8)
  • Five months ( $10)

etc.

  • Six months ( $12)

So, the user can choose any plan from the above and then continue on to pay the amount on PayPal. This page will be available to users who have accounts on our site. therefore, we can transfer all the data of the current user to PayPal, such as - name, email address, etc.

I tried to read many articles on how to integrate paypal, but none of them helped me. Since I am new to codeigniter.

I also created a Paypal and sandbox account on paypal. I downloaded php-toolkit from sourceforge.net and used it myself, then it works correctly. but when I try to implement in codeigniter, it will not go anywhere.

Please help me!
