title: Make Transactions with PayPal and PHP
body: <p>So I have a basic form for the users Name, Email, Address, and Gender. At the end is a normal Submit button and the Form's action is a file called register.php which uses POST. It then does a standard check to see whether the information entered was correct. But now I want to integrate PayPal payment into it.</p>
  
  <p>Now, if you can head over to <a href="https://btguard.com/join?service=socks" rel="nofollow noreferrer">https://btguard.com/join?service=socks</a>, the site works pretty much just like how I want mine. Enter your info, it checks if it's legit, then it sends you to a payment page <a href="http://img.photobucket.com/albums/v248/NessDan/BillingInformation-PayPal_1280767417135.png" rel="nofollow noreferrer">Example of Payment Page</a>.</p>
  
  <p>When PayPal comes up, it should charge $99 if it's before Oct. 8, $129 afterwards. Then, if they do complete payment, it would add them our database (but how would PayPal let you know if they paid or not? Through POST/GET data?)</p>
  
  <p>I've never used an API before but if someone can provide information on the PayPal API I should use, I'm a quick learner. Thanks for the help.</p>
