vanishing variable names php4 IIS5

[gartside]

I have a problem with IIS5 and php 4 on my 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 believe this is probably 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 $file-1;
echo $sometext;
?>

//THE INPUT VALUES

'c:\randomtextfile.txt' //(SMALL text file [<5Kb] selected as input for file-1 using browse button)
'here's some text' //typed in manually to text box "sometext" in form

//THE RESULT IN IE5.5

Notice: Undefined variable: file-1 in c:\test.php on line 8
here's some text

So, why aren't the file type inputs coming thru? Thanks for any help offered, it's probably a simple config problem I can't work out.

It's easier to work with register_globals off (or at least assume it).
Then the other form fields will be in the $POST array, and the files in the $FILES array.

Also, note that "$file-1" is not a valid variable name (that's "$file minus one"). I'm surprised it's even being recognised as a variable. If it was converted in some way (replacing the hyphen with an underscore, for example) that might do it; you'd have to list all of the defined variables and see if you can spot it in there ... which is one more reason why using $_FILES is preferable.

Or it may be an IIS configuration thing. Perhaps the Windows forum would have more specifically experienced helpers.

Thanks, but changing the variable name makes no diference, nor does working with the _POST array and register_globals off (tried both before posting).

I'll try on the windows forum, thanks.

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.
