Code

This code allows the administrator to set the root position for public file browsing on a server. Good for browsing libraries of files.

The attached file contains the images.

Hello, Thanks for your example! I found a missing component from the example "PHP Directory Listing" however. The code below fails to produce a correct link. It begins the link with "<a" and then fails to produce any "href=url" at all. For example: "<a class=`g`><img src=`dlf/jpg.gif`><strong>pict0256.jpg</strong><em>201 KB</em>Nov 30 2005 05:45:00 PM</a>" The failed code is listed below: -------------- if (strlen($files[$x]) > 70) { echo "<a class=`g`><img src=`dlf/" . $icon . strong>" . substr($files[$x],0,70) . "...</strong>"; } else { echo "<a class=`g`><img src=`dlf/" . $icon . "`<strong>" . $files[$x] . "</strong>"; } -------------- Thanks Again! Phil
