Hi PJ,
You can use the structure following
$bid = htmlentities($_GET['id']);
if(empty($bid) {
$bid=0;
}
if(is_numeric($bid)) {
if($bid==0) {
do something
} else if($bid==1) {
do something
}
}
After this code there will always a number, If the id variable is 0, bid
will be 0 and you can control it.
Thanks.
Caner.
