You can store the value in a session variable session_start(); if (isset($_HTTP_SESSION_VARS['your_variable_name'])) {

</snip> Rather than using isset() you may need to use session_is_registered(). This is specifically for checking the existence of a session variable. I would do something like <?php // need this on all pages where you want to work with // the session var session_start(); // Check for the existence of the session var and create // it if it doesn't exist if (!session_is_registered("ses_username")) {

        session_register("ses_username");

} // Are we getting a form var thru ? if so pop it into the session var if (isset($frm_username)) {

        $ses_username = $frm_username;

} // then in your scripts you can do do_my_amazing_function($ses_username); ?> As long as you have session_start() at the beginning of each script, $ses_username is now available across scripts. <snip>

$value=$_HTTP_SESSION_VARS['your_variable_name']; //get the value }else{ $_HTTP_SESSION_VARS['your_variable_name']=new value; }

</snip> Hope that helps.
