vanishing form variables IIS/PHP4/W2k

[gartside]

I have a problem with IIS5 and php 4 on my W2K web development testing machine.

Form variables from input type="file" disappear without ever being available on the php action page. Other form variable types are fine.

php.ini register_globals is ON. file-upload is ON. Size is default. I have also tested with register_globals OFF using _POST array.

I beleive this is a problem with how I have configured IIS on my Windows 2000/PHP development machine, but simply can't find anything about this problem in IIS forums, so I'm trying here. I would deeply appreciate some help.

Here is my code, stripped to a minimum:

//THE FORM

<form action="test.php" method="post" enctype="multipart/form-data" name="form1">
<input name="file-1" type="file">
<input name="sometext" type="text">
<input type="submit" name="Submit" value="Submit">
</form>

//THE TEST.PHP CODE

<?php
echo $file1;
echo $sometext;
?>

//THE INPUT VALUES

'c:\randomtextfile.txt' (SMALL text file [<1Kb] selected as input for file1 using browse button)
'here's some text' typed in manually to text box "sometext" in form

//THE RESULT IN IE5.5

Notice: Undefined variable: file1 in c:\test.php on line 8
here's some text

Also, could it be my directory permissions on Windows2000?

Thanks for any help.

Sorry, there is a typo in the first post. The line that reads:
<input name="file-1" type="file">
should read:
<input name="file1" type="file">
That should save some time!

Well, hope I didn't waste anyone's time too much.

Here is the solution in case it helps anyone else.

PHP creates a temporary copy of the uploaded file in the directory specified under the file_upload section in php.ini. I had mistakenly restricted the permissions on this directory, failing to allow "write" to everyone.

It seems that because of this, the filename variable is never created, therefore unavailable. Works fine now. I may be able to remove the write permission for everyone and replace it with IUSR_MACHINENAME later, haven't tried that yet.
