updating global variables
how to cary new variables to other pages

 4:46 am on Sep 17, 2012 (gmt 0)

e.g. I fill in a form for an inquiry on a used car. Then all the other used car inquiry forms will contain the value that I used in the previous form.

How can you create the variables that will used again on another page.

assuming all of your pages are in the same domain, $_SESSION is one way to do what you want.
After submitting your form, you can assign $_POST data to $_SESSION
for example:
$_SESSION['myVar'] = $_POST['myVar'];

session_start() must be always ontop of all your scripts if you're gonna use sessions.

Start reading about $_SESIONS here [php.net]

In addition to using a session, other options are to pass values as hidden fields in the forms; store values in cookies, or store information on the server (for example, in a database).

Oh right, thanks Roger, that makes sense.
