No. You should read (repeatedly if necessary) manual > Session Handling Functions and try out the examples and understand what's going on. Executive summary: do not enable register_globals $_SESSION['variable'] = 'something'; // to register a session variable > If I send this form action post to a page where I > have: > <?php > session_start(); > ?. > .............. > <?php > echo "\$myname = ".$myname."<br/>"; > ?> $myname is taken straight from your form, and because you have enabled register_globals it is available in the GLOBAL scope. That has nothing to do with your sessions. > The variable print out fine. > BUT - if I add another page between first and > printout, > echo "\$myname = ".$myname."<br/>"; - returns nothing 1) understand the paragraph above 2) realise that at no stage have you actually registered any session variables 3) realise that you have not propagated $myform from page2 to page3 either through a form or through the URL hence $myname is not available on page3.
