Looking for a delete file script

I am looking for a tutorial or help creating a delete file script. The multi-upload tutorial on this site is great, but a suggestion at the end led me to wonder if anyone has seen a script posted for the use of a multi-delete function. I've written on that requires more work on the user's side than I want to put them through. Has anyone seen anything easy?

I also am looking for an online editing script for editing php. I was on a month ago asking this same question, and found a site with a contest for an online editor. The results are fantastic, but much more than I want to tackle. I'm just looking to delete files and edit files online.

Just a point in the right direction is all I ask. Thanks.

One more...duplicate entry. I have a form that submits a duplicate entry if the user uses the back command. Any ideas for this?

lbd

for the delete, store the file names in a database,
then build your delete "full paths" from the file names
in the db, and use the php unlink() function to remove the files
As far as the back / dup entry thing, store a session value upon first submission
such as $_SESSION['Form1_AlreadySubmitted']=true;

Then simply check for that before session variable before performing the action

eg.

if(isset($_SESSION['Form1_AlreadySubmitted'])){
//...
}else{
//...
}
