It would probably be best to use JavaScript to check for that before the file upload is actually attempted.

Try this script. :webdev:

What are you using as the upload script, PHP, perl, other?

I think you can check for file types with PHP by doing something like this:

PHP Code:

  if($HTTP_POST_FILES['file']['type'] != "image/gif") {

your code here, probably some code to delete the file

}

file would be the name of the input field in the form.

Hi thanks for the help on this (im the mate adam is refering to).

What im actually trying to is set the file field so that when you click browse jpg is the only selectable file type from within the browse window's file type drop down.

I'm sure ive seen this done before i just cant remember where!

Any and all help is appreciated.

Cheers
Carl

I think I may have seen that done somewhere also, but I don't know how or if it's even possible to do from a web page.

I imagine vbScript would probably be something that you may be able to do that with, but I really don't know much about vbScript/asp.

There's the accept attribute that you can use to list what content-types the server can handle correctly.

If I ever learn how to do what you're wanting, I'll be sure to post it here.
