Use $_REQUEST['posted'] instead of $_POST['posted'] and add the "posted" variable to your URL. myscript.com/my/path/myscript.php?slapper=whatever&slapee=whatever&size= whatever&mode=whatever&posted=something $_REQUEST contains GET, POST, and COOKIE data, so using a form or URL with "posted" in it will create that variable within $_REQUEST. > So my question is, is there any way I can look for part of a string, or > do an approximate comparison?
