Filename: Replace spaces with underscores

you can't change the filename before the file has been uploaded to your
server.

upload a file using cffile.
#cffile.serverfile# variable will contain the name with which the file
has been saved on your server.
check if the name contains any spaces using find() cf function.
if it does, use cffile action="copy" to copy the file as a file with no
spaces in the name (use replace() cf function to replace spaces with
whatever you want).
[you may want to make sure prior to copying the file that there is not
already a file with same name (with no spaces) in that folder, otherwise
the copy action will overwrite existing file]
delete original file.

details of all the functions are in the CFML Reference. if you do not
have one - download free from adobe.com
