Make a php script to have it list all the .pdf files in your pdf directory. That way you won't have to worry about it not being up to date. All it takes is something like this:
PHP Code:
<?php
$pdfs = scandir('pdf/directory/');
foreach ($pdfs as $v)
{
if ((stripos($v,'.pdf') !== false) && (strpos($v,'.') !== 0))
{
echo '<a href="pdf/directory'.$v.'">'.$v."</a>\n";
}
}
//Unless server is still on PHP 4, then things get more complicated as you'll have to make your own scandir function and will have to use strpos instead of stripos. Use phpinfo() to determine server information (unless that has been disabled too).
?>
