[FX.php List] Retaining $_POST Requests in Form Redux

[Dale Bengston]

You should not need to serialize $_POST to store it in a session  
array element. Each element will be named the same as its POST  
equivalent. It's just one level deeper in an array. Given a form with  
these inputs,
	<input type="hidden" Name="first" value="this">
	<input type="hidden" name="second" value="that">

...and that you store them in a session variable like this:
$_SESSION['postvars'] = $_POST;

You have now stored the post array in an element of the $_SESSION  
array. Then you can address the individual elements like this:
	$_SESSION['postvars']['first'] //value is 'this'
	$_SESSION['postvars']['second'] //value is 'that'
