title: Variable 3rd party paypal Shopping cart
body: <p>Simply put a flexible check out paypal button using your own shopping cart.</p>
  
  <p>one that sends each product plus quantity to the paypal payment page.
  I've seen codes for multiple products, but those are not flexible. for example Payment for 2 unique items. but what about if the user buys X amount of different products? when only allows a fixed amount.</p>
  
  <p>Referring to <a href="https://stackoverflow.com/questions/3308898/paying-for-multiple-items-at-once-via-paypal">This page</a></p>
  
  <p>Is this possible to do in PHP? If so I was thinking of something easy like an array listing each product with in the button form.</p>
