[geeklog-devel] Re: Article throttle.

[Justin Carlson]

I should probably clean this a little for read-ability, and so it does
not query if the throttle is not on:

// Throttle
if($_CONF['throttle']>0){
    $rs = DB_query( "SELECT DISTINCT uid,remote_ip FROM
{$_TABLES['sessions']} WHERE uid = 1" );
    if(DB_numRows($rs)>=$_CONF['throttle'])}{
        if(!eregi($_CONF['site_url'],$_SERVER['HTTP_REFERER'])){
        $mode='print';
        }
    }
}
