Multiple File Upload

I'm looking for a good tutorial to integrate multiple file uploads
into my forms. Like in Mephisto. I can find very little and have
been looking into it for days. Can anyone point me in the right
direction or provide me with a complete example (controller, model,
view)?

thanks in advance.

Mephisto’s source is available… perhaps you could check there. I always learn a lot by looking at Rick’s code.

so after being thoroughly disappointed in every forum post i've ever
read and every solution, I looked into mephisto and reread the pickaxe
and AWDWR 2nd editions and came up with my own tutorial on multiple
file uploads with file field arrays. it borrows heavily from mike
clark's tutorial and downright steals from mephisto.

check it out.
