[FX.php List] Passwords

[andy at fmpug.com]

Peter -

Look into Sessions with PHP http://us3.php.net/manual-lookup.php?pattern=sessions. When you use sessions you need to ensure on each page you start with a session_start tag. 

session_start();

You can also set your php.ini to auto start sessions for you

When your users log-in you can set a session variable to their access level;

$_SESSION['accesslevel'] = 'x'

where x is either a, b or c

Then when you go to those pages you can check the session variable value. If access is not allowed you can use a header redirect to take them out of the page.

<?php 
session_start();

if ($_SESSION[accesslevel] != 'x')) {
//Set x to the relevant access level
//Access not allowed for this page
	$thankyouurl = "index.php";
	header( "Location: $thankyouurl" );
	exit;
} 
?>

I find the easiest way to ensure the session is started is to place that call in an included php page that is on every single page.

Anyhow, hope this helps you out.
