I have a script that allows users to download pdf files from my site.
To make it simple as possible i just dump a new file in and thats it.
How i make it work is simple.
I turn the file name into effectively an array.
$x = explode("_",$filename);
$title = $x;
$description = $x;
Order displayed is of course automatic as youve discovered. So just put A or B etc or 1 or 2 etc in the file name at start.
