Hello. Does anyone know why strip_tags() is apparently returning an empty string in the code below? If I get rid of the strip_tags(), it works, but with strip tags, it displays the message about no ticket number being entered. I'm just sending it "http://[omitted].php?ticketNum=1", so there aren't even any tags to remove. This is modeled after some code a professor gave me that worked before, so I'm stumped. Thanks in advance.
if (isset($_GET['ticketNum'])){
if (get_magic_quotes_gpc()){
$_GET['ticketNum'] = stripslashes($_GET['ticketNum']);
}
$ticketNum = trim(strip_tags($GET_['ticketNum']));
}
if (empty($ticketNum)){
$results['success'] = 'false';
$results['reason'] = "No ticket number was entered.";
}
