IMO, writing programs that work without register_globals to be enabled, is a good thing.
Throughout the book, the code examples will have been created with register_globals on. (The default setting for older PHP installations/versions) just keep in mind that variables are not auto created for you, so you must initialize them first. $author = $_GET['author']; if you change the form method to POST, then you will have to modify the code to reflect that too. Anyways, explicitly initialising your variables is a good habit to get into. Its more secure. -----Original Message----- From: Dash McElroy [mailto:[EMAIL PROTECTED]] Sent: Sunday, 12 January 2003 3:49 PM To: Wade Cc: [EMAIL PROTECTED] Subject: Re: [PHP-WIN] Using the GET Method Ah, You're the latest of the ones to get hit by the register_globals setting. There are two things to do: 1. Change your code to reference the METHOD referenced in the form page GET -> $_GET['varname'] POST -> $_POST['varname'] COOKIE -> $_COOKIE['varname'] SESSION -> $_SESSION['varname'] GPC (Get Post Cookie, in that order) -> $_REQUEST['varname'] See php.net/register_globals for this. 2. Change your php.ini settings from: register_globals = off to register_globals = on then restart your server. Now, I just have to ask myself why I don't have a canned message for this... -Dash Know thyself. If you need help, call the C.I.A.
