Yes. You are missing the point.

This is exactly the same; you don't need $_SESSION's in this case because all you're doing is POST'ing the data every time..

And that's what you are missing -- it's not continued POSTing! Follow closely, http://www.webbytedd.com/bb/php-run-php/ While I'm using a Submit Post button to go from this script to the next script I am NOT sending any data via the POST. To prove it, use FF and see what's passed. All data is passed/available to the next script because the next script is an include. For example, this parent script has the variable: $test = "This is a test"; And the next script (either a.php, or b.php, or c.php -- your choice) simply echo's $test. Please note, the contents of the variable $test was NOT passed via a POST, but rather retained because the parent script included the next script. Do you see the difference? Here's another example presenting the same technique in a different way: http://www.webbytedd.com/bb/tedd/index.php All the variables remain intact AND there is nothing in the REQUEST, SESSION nor COOKIE arrays. I have a hard time trying to get people to understand this simple concept. It's so simple that people often overlook how powerful it is. For example, with a little forethought, I think there isn't a script I've written that I could not have used this technique and dispensed with SESSION's all together. That's pretty powerful, don't you think? Do you understand what I'm doing now?

no ill-intention meant.

That's Okay -- I realize you meant no ill-intent. Neither do I -- I realize that occasionally simple concepts are hard for you smarter guys to get because you have to dumb down a lot to consider what we're talking about. But I think it's an interesting concept to consider. Cheers, tedd

at it's simplest is this correct..? index.php <?php $variables = $_POST; include 'anotherscript.php'; ?> anotherscript.php <?php print_r( $variables ); //include has access to $variables from parent print_r( $_POST ); //include has access to post data as well ?> I'm struggling to follow here I thinks! lol

I don't think you're missing the point Nathan, I think you've hit it on the head. This technique does not solve the problem of passing variables between requests. I think the only benefit here is to avoid having to repost data by including the next script rather than bouncing off the browser. Or maybe I'm missing the point. -Stut -- http://stut.net/
