Note Submitter: luzian dot NO at SPAM dot london dot com ---- Just a reminder if you use sessions: Be careful when you want to use header('Location: XXX'); as a redirect to XXX. In fact, previously written session variables might not be correctly written, which results in loss of these variables in the called script. So if you use sessions, ALWAYS use session_write_close(); BEFORE a header redirect. This makes sure that the session variables previously set by $_SESSION['foo'] = bar; or session_register('foo'); are actually written to the session database before the script is terminated. So a tasty bit of code would be: <?php // whatever you do before, including setting session variables $foo = "bar" session_register('foo'); $_SESSION['foo2'] = $foo; // etc. // so now the important part: session_write_close(); // write session header("Location: http://server.com/file.php"); // redirect exit(); // terminator :o) // that's it! ?>
