When allowing the user to upload files, is there a way to verify the file name before the upload starts?

This is to avoid problems with spaces and special characters in file names, which can cause problems when downloading the file.

A way to automatically replace spaces with underscores would be very useful.

So do I assume that it is not possible to check file names before uploading?

I would appreciate a reply to this question ...

Thanks!

Adam,

I'd really like to get that code for checking file names, and to automatically replace spaces with underscores...

I just purchased a server license for CuteEditor, and I want to deploy it this weekend, but I can't allow the users to upload files with spaces or special characters in the names, because that gives problems to download them.

Many thanks

Thanks Adam, I'll check it out over the weekend, and let you know.

Adam,

Thanks for the mods. I have tested them and found a couple of problems:

1. In FilePost.asp, the new function ValidFileName only allows extensions gif, jpg, jpeg and png. This conflicts with the function ValidFileExtension which allows many more. Also, ValidFileName is used both for file type "document" and "image".

2. The ValidFileName function doesn't allow the hyphen character, which is often used in file names. The "\w" character class only allows alpha characters, numbers and underscore.

So to fix both the above, I changed the regexp pattern to: "^[a-zA-Z0-9\._-]+$"

What I would really like, is to automatically replace spaces with underscores when uploading. This would save the user a lot of time. Could you possibly modify the upload to do that?

One other thing, what were the changes in insert_document.asp ?

Regards, Torq

Great job on this fix.  I was jsut noticing this problem this evening.
