Hi,
Long question.
Short answer: sessions
A session can be started by adding session_start() at the beginning of each
script.
You store values in a session like in any other associative array, like
this:
$SESSION["visitorname"] = $MyReceivedName;
and retrieve this value from another page like this:
echo $SESSION["visitorname"];
You can store about any value and also complete arrays in a session.
Read more at www.php.net, look up session.
Good luck,
Regards,
