How is it not working? What does var_dump($attributes) show? > I list my $HTTP_SESSION_VARS, there are none. Is this related to the above? $HTTP_SESSION_VARS would normally be empty unless you start a session and register some session variables. > I would appreciate anyone taking the time to explain to me how this works. > Either it's stupid or I'm stupid. I'm figuring it's me. 1) Usually there is little point putting the request variables ($HTTP_POST_VARS, $HTTP_GET_VARS, $_GET, $_POST) into the local namespace. Just use them directly as you have here: > switch ($_POST['action']){ > case "Add Record": > ...do stuff... 2) If you really must do (1) then instead of: extract($attributes, EXTR_PREFIX_SAME, "this"); you should probably use this: extract($attributes, EXTR_PREFIX_ALL, "this"); that way you'll know that variables prefixed with 'this' came from $HTTP_POST_VARS, $HTTP_GET_VARS. BTW why are you processing $HTTP_GET_VARS? You're using "POST" for your form. 3) To save confusion use only the new "superglobals" ($_POST, $_GET etc) OR only the old, deprecated request variables ($HTTP_POST_VARS, $HTTP_GET_VARS). Do not mix the two in the same code.
