   <li>Sample PDF eBook <small>[ <a href='dl.php?id=6V001313X66714025&file=1'>DOWNLOAD</a> ]</small></li>
   </ul>

   <ul id='dlist'>

   <li><a href='dl.php?id=6V001313X66714025&file=1'>Sample PDF eBook</a></li>
   </ul>

When the download link has expired, the expired message will be put out in a

tag, with ID "expired". Here's an example:

   <p id='expired'>Your download has expired</p>

You can use the ID's "dlist" and "expired" to style your download page with CSS.

While Simple IPN can work with multiple files in your product package, Simple IPN is not designed to cater for multiple products.

To use Simple IPN on your other products, copy the files of Simple IPN into a new folder and define your settings in the settings.php file.

Just like how you previously link to ipn.php?buy, do the same for this new product. Make sure you link to the right file from the right folder.
