run phpinfo() to make sure your register_globals (I assume that is the option you are referring to) is enabled.

YES, register_globals is On!

There are times when submit buttons don't pass values. I always forget the exact circumstances so rarely rely on them but anyway, assuming this is a post form, do:

var_dump(array('p' => $_POST, 'r' => ini_get('register_globals')));

Of course, use $_GET for GET.

I am attempting to port an existing app from php 4.2.2 linux (apache) to Windows XP (iis 5.1) php 4.3.2 -> I do have register globals turned on but I am still getting the Underfined variable messages on any session vars.  Any one else encounter this problem?

Thanks!

I am having the same problem.  I have a PC running Windows XP Pro and it has PHP 4.3.4.  It is really annoying.  Someone posted that they downgraded to 4.0.6 and it fixed the problem.  Here is a test I ran on it and the results....

I created a file called "temp.php":
---
<?php if (!$text) { $text = "Enter Text Here"; } ?>
<form action="temp.php" method="post" enctype="multipart/form-data" name="form1">
  <input name="text" type="text" id="text" value="<?php echo $text; ?>">
  <input type="submit" name="Submit" value="Submit">
</form>

Here is the error it returns...and yes register_globals is "On".  It does nothing to help the issue....
---
Notice: Undefined variable: text in d:\---filepath---\temp.php on line 1

I have a site residing on my development server (debian/linux) that works flawlessly.  On porting it over to a windows server (same version everything), I keep getting these undefined errors.  What can I do about this?
