I wrote a web based ftp client using php5 and RAD upload (http://www.radinks.com/upload/) and I am getting strange results when using -some- instances of IE (versions 8,7, and 6 have been tested).

The upload is ultimately getting its information from a simple html form using the input type="file" tag. So the users are all using the "browse" button provided by this tag, moving to a document on their filesystem and clicking submit. In all cases the file uploads succeed. The problem is that on IE in most cases the filename on the server ends up being the full dos path of the file on the client's machine.

For example, if I upload a file "c:/documents and settings/mike/desktop/Image001.jpg" it shows up on the server file system as a single file named "c:/documents and settings/mike/desktop/Image001.jpg". The server is running CentOS 5 and can handle this name, but it is ugly and looks wrong. It also breaks my display and download script, but I can fix that part if I have to deal with these filenames.

On my copy of IE8 and all copies of Firefox 3.6.3 that I have used have worked as expected and shows up on the server as "Image001.jpg".

Any thoughts/workarounds/solutions would be appreciated.

Without poking through the code, I can only suggest to you what I did for my own software: Deny IE and/or put up a big, ugly warning box about using it.

I had similar issues, and decided that I wasn't going to ignore web standards and best programming practices, to 'fix' a browser that was broken. I put a disclaimer that essentially said "use a standards-compliant browser, or quityerbitchen", and moved on. Some folks complained, but most were happy about it, since page loads were faster (less code and work-arounds, obviously), and it forced some managers to quit dragging their feet about upgrading stuff.

Just FWIW.

Also make sure you have enctype="multipart/form-data" and method="post" as attribute to the form tag in the html. I can't remember seeing such filenames on uploads, but I remember strange things happened without.

This is the form. postIt just checks the form for valid data.
The other parts are from the RAD package. I don't believe I made any significant additions or deletions besides some configuration type things.
I can post the rest of it, but it is spread over several files and would be a few pages of code probably.
