I think it's a problem with your browser, not with PHP. Anyway, can you try the latest RC from www.php.net/~derick ?

You're right about it being browser related.  Uploading zip and visio files works with IE 6, but not with Netscape 6.2 or 4.7x and not with IE 5.0.  I haven't tested IE 5.5.  Our admin will compile and install the latest RC in the next few days.  I'll report back on how that affected uploads of our problem files.

If this problem persists, it would be very helpful if you could capture (or have someone else capture) the underlying HTTP traffic this transaction produces.

Feel free to email me personally if you would like help in this regard.

any news here?

Finally we have PHP 4.20 installed.  It does solve the problem for uploading zip files with Netscape 4.7.  It still doesn't allow the successful upload of visio files. It puts the file on the server with the correct name, but its a zero KB file.

These PHP commands: 

echo "HTTP_POST_FILES tmpname: ".$HTTP_POST_FILES['attachment'] ['tmp_name']."<br>\n";
echo "attachment_name: ".$attachment_name."<br>\n";
echo "attachment: ".$attachment."<br>\n";
echo "attachment_size: ".$attachment_size."<br>\n";
echo "attachment_type: ".$attachment_type."<br>\n";

result in this output: 

HTTP_POST_FILES tmpname: 
attachment_name: test.vsd
attachment: 
attachment_size: 0
attachment_type: 

PHP 4.2 can get the name but little else from a visio file. 

I'll see if I can get one of the server admins to look at the http traffic that happens during the upload of visio files.

I really think this is a browser issue. What happens if you rename a viso file to .jpg or .gif, or any other extension that does work? If you can upload that file, then it's a browser problem.

I get the identical response after I renamed the file to have the extension .jpg.  Using IE 6.0, Netscape 6.2 or Opera 6.2 doesn't work either for visio files. It looks like visio is the only problem file type. 

This isn't a big problem for us.  I was asked to add a file upload feature to an application, but so far no one has uploaded any files.

Let me guess: the visio file you're uploading is big?
And your php.ini settings for upload_max_filesize and post_max_size are smaller and that's why the file is never
gonna get there..

Try this very simple example:


<form method="post" name="form" action="uploadtest.php" enctype="multipart/form-data">
<input type="file" name="attachment">
<input type="submit">
</form>
<?php print_r($_FILES); ?>

And try submitting one of those problematic files and
paste the output here.
