title: codeigniter paypal url
body: <p>I have downloaded the codeigniter paypal lib. I have few questions regarding this library. </p>
  
  <ol>
  <li><p>My paypal url is set to this, $this->paypal_url = 'https://www.paypal.com/cgi-bin/webscr', Is it for testing!? How can I change it for actual transactions?!</p></li>
  <li><p>My return url is set to a success controller, but I am not able to view the post information returned by paypal. Could anyone tell, what exactly is the problem?!</p></li>
  <li><p>I want to store the transaction details (Amount paid,paid by whom, on what date and for which product), How exactly I can achieve this?</p></li>
  </ol>
  
  <p>thanks</p>
