Subject: Re: [ACFUG Discuss] looking for opinions on duplicate form
submissions
Put a unique identifier in the form request, store it in the user's
session before form submission. Once the form is submitted check to see if
the value matches. If so delete it from the session and continue
processing. If the token doesn't match or is nonexistent in the session,
then its a duplicate or out of order submission.

I'm working on an application where a form is submitted along with
various attachments (doc, pdf, xls, etc). Apparently users are submitting
the same request several times and I've been asked to address this issue.
At first thought, it seemed quick and simple to me, but as I've started
working on it I can't decide exactly how to handle the attachments in
associated with the form in the most efficient way.
That brings me here. I was looking for suggestions on how to handle the
attachments while I run validation on the db to see if the input from the
form already exists in the db. It seems like something that would be
perfect for AJAX to handle, but my AJAX skills are virtually nonexistent.
So, without using AJAX (or if you can break it down using AJAX for a novice)
how would you handle the situation?
The main issue I'm having, is that if I do the validation after the form
submission, CF is assigning a temp directory to my attachment file. So what
is submitted as this: "C:\Documents and Settings\JHoward\Desktop\PO Request
mods.doc" ends up as this after submission and validation:
"C:\ColdFusion8\runtime\servers\coldfusion\SERVER-INF\temp\wwwroot-tmp\neotm
p13963.tmp " and then when I pass it to the CFFILE, it tells me the file
doesn't exist.
I'm really just looking at the different ways other people would handle
this situation to try and decide so any input would be great.
Thanks in advance.
Jeff
