Form handling

[dan <info@xxxxxxxxxxxxxxxx>]

Hello, all -

I've been researching how to handle forms properly, and I think I 
figured out a way that might be beneficial for me to use.  It is as follows:

(index.php)

session_start();
if (isset($_SESSION['step'])) {
	switch $_SESSION['step'] {
		case "1":
			require('step1.php');
			break;
		case "2":
			require('step2.php');
			break;
		case "3":
			require('step3.php');
			break;
		// add more case statements here if I need to
		default:
			require('step1.php');
			break;
	}
} else {
	$_SESSION['step'] = '1';
	require('step1.php');
}

Each stepX.php file would look something similar to this:

(step1.php)

// if submitted, check data for completeness
// if complete, set 'step' to 2, to be used as argument to index.php
	$_SESSION['step'] = '2'
// redirect back to index.php, use new value of 'step' to direct
	header('Location: http://somesite.com/index.php');
// else display form data




Now, this is, really, one of my first experiences with doing forms.  I 
just want to know if I can/should/would anticipate any problems down the 
road while doing this.  I think it would work quite well, but I've only 
been doing this for a short while.

Thanks!
