RE: [PHP] "Use of undefined constant" error

Hi, > "Notice: Use of undefined constant id - assumed 'id' in ..." Try changing this: > if(isset($_GET[id])){ to this: if(isset($_GET['id'])) { ^^^^ note quotes PHP thinks you're trying to use a constant called "id", which you haven't defined - hence the "undefined constant" error ;-) Note how the message says "assumed 'id'", which is what you should change it to - this shouldn't stop your script from running, as the parser can work out what you meant, but your error reporting is set sufficiently high that PHP lets you know about it.
