Unable to read POST variables...

Helllo,

I am trying to create a page that calls itself and checks for variables. I am having some problems, so I figured I would create a simple test page and even that one does not work for me. Here is the code....can anyone help? Thanks!!

<?php
$message="";
if ( ! IsSet($PostVar) )
{
$message="Welcome...please don't forget to set the PostVar on your way out!";
}
else
{
$message = "Thanks for setting the PostVar";
}
?>
<html>
<head>
<title>Self-Fulfilling Prophecy</title>
</head>
<body>
<h1><?php print $message ?> </h1>
<form action="<?php print $PHP_SELF?>" method="POST">
Set the post variable here: <input type="text" name="PostVar">
<input type=submit>
</form>
</body>
</html>

Just found out why this (and many others) did not work anymore. Apparently, the latest builds of php have the "register_globals" setting in the php.ini file set to OFF as the default. Previously this setting was true. So, once i set it back to ON everything worked fine.

Apparently, one reason this change to the default setting was made is to make php code more secure. Now that I know everything is working, I'll probably reset to the default (OFF) and modify my code to get the variables as the Release notes suggest.

i personally find that the global command stops the errors, regardless of what version of php you are using

global $PostVar;

using globals is not good way of programming.
It makes your code less flexible.
IMHO
