How do I check for the presence of an optional $_GET param without throwing a "Notice: Undefined index" when the param is not present?
Tried all three of these, they all produce the Notice when the param is not passed:
if ($_GET['id']) if ($_GET['id'] != "") if (isset $_GET['id'])
isset should *not* be throwing a notice, that's what it's for. Try using parenthesis.
if(isset($_GET['id']))
