RE: File upload and make unique
Robert,
At first glance, I thought this would work, but after looking
closely at the code, it does nothing more that what makeunique already
does, just adds a 1 to the end of the file name if not unique, thus each
time you use the routine, you end up with a file name that increases in
length by 1 char. I may be able to adapt what you sent, by grabbing the
number at the end of upl_fle_nme, taking a val, increment that, and
replace the number into the name and then checking for prior existence.
So you have still helped me go in the right direction.
Jerome

Assuming you are uploading from a form and the name of the file field is
"file", the routine below will do it. You will need to rename the paths
as
necessary. This routine will:
1) Rename the file with incremental numbers (1, 2, 3, etc)
2) Ensure the file name uses only standard characters (so it can be
used in
URL strings if you want to link to the file)
3) Report back the final uploaded file name as the variable "upl_file"
4) Prevent users from uploading dangerous file types (.cfm, .com, .exe,
etc.)
Hope this helps.

Rename it before giving it back to them. Not idea, but then you can't control the users OS. Adrian > -Original Message- > From: Huff, Jerome P.
