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.

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.
