Another newbie here toughing my way through the PHP world. I have been plugging away at this upload/download script for some time now. I have it working just great with one exception...I can't delete any files after they have server their purpose. This started out as a borrowed script with my twists and changes to it making it work for me. All I want it to do is list the files in the directory so I can choose which ones to delete.
Here is what I have, please have a look and maybe guide me in the right direction. If anyone is looking for a great upload/download script this is a good beginner one.

I have had this before the prolem usually is that since php runs as nobody you have to have nobody permissions to remove anything it creates.
So you need a delete script.
for your switch you need a case for 'delete' where it just does something like
case "delete":
$file_id = $_GET['fid'];
unlink($file_id);
echo '<p>I just deleted the file with the id of ',$file_id;
break;
now this doesn't really fit exactly, you may have to pass the filename or whatever you use to keep track of the files. How you could pass it is to have a link, or a form and use $_POST, that goes to this script and passes it the filename or file id that it needs to delete.
I would suggest this method for some type of private area or you may find files deleted that you still wanted.
that's roughly the logic of the whole thing though.
Thanx
