title: Guidance related to Paypal Integration Using Codeigniter
body: <p>I need some guidance related to PayPal Integration. It's not similar to a regular cart.
  After checkout, the site offers a form for payment option. Either it's PayPal, or some other payment process. The form directs to controller after the user submits. An array exists, which contains all item values.</p>
  
  <p>From here on how can I proceed to the Paypal site?</p>
