I'm looking for a mod to change my default theme when my site hits a certain amount of online users. I haven't seen one that exists already but if there is i apologize (and would like a link) icon_smile.gif

Does anybody out there feel like working on this with me? I know nuke very well.... but i'm not a coder at ALL. I would think it shouldn't be too hard and i think it would be a useful mod that a lot of people who lack dedicated server resources would utilize.

If you think you're able to tackle this or can point me in the right direction i would REALLY appreciate it!

Thanks,
Diab

If there a user then there theme is stored in thier cookie kinda hard to change that unless you re set the cookie and do a page refresh everytime you hit the number. Now for people that arn't a user you could just do something this inside your function online located in your mainfile.php. If you paste the code I'll show you what to put there.

Thanks a bunch man. Yeah, i'm not worried about users logged in, only visitors. In 99% of the situations when a lot of users are online they're mostly visitors.

Here is my function online... running PNP 7.6

function online() {
    global $user, $cookie, $prefix, $db;
    cookiedecode($user);
    $ip = $_SERVER["REMOTE_ADDR"];
    $uname = $cookie[1];
    if (!isset($uname)) {
        $uname = "$ip";
        $guest = 1;
    }
    $past = time()-1200;
    $db->sql_query("DELETE FROM ".$prefix."_session WHERE time < '$past'");
    $result = $db->sql_query("SELECT time FROM ".$prefix."_session WHERE uname='$uname'");
    $ctime = time();
    if ($uname!="") {
    $uname = substr("$uname", 0,25);
    if ($row = $db->sql_fetchrow($result)) {
   $db->sql_query("UPDATE ".$prefix."_session SET uname='$uname', time='$ctime', host_addr='$ip', guest='$guest' WHERE uname='$uname'");
    } else {
   $db->sql_query("INSERT INTO ".$prefix."_session (uname, time, host_addr, guest) VALUES ('$uname', '$ctime', '$ip', '$guest')");
    }
  }
}
]

*edit* just some quick notes...
if the # of users could be easily configurable though a variable or whatever that would probably help keep the mod nice and easy. also, it's probably obvious but the code should check for greater then X amount of users then change to the "lite" theme but also check for less then X amount of users to change it back to the default theme. thx again in advance.

Try this out..


function online() {
    global $user, $cookie, $prefix, $db;
    cookiedecode($user);
    $ip = $_SERVER["REMOTE_ADDR"];
    $uname = $cookie[1];
    if (!isset($uname)) {
        $uname = "$ip";
        $guest = 1;
    }
    $past = time()-1200;
    $db->sql_query("DELETE FROM ".$prefix."_session WHERE time < '$past'");
   
    $maxswitch = 100; //Online number that theme will switch at
    $maxswitchtheme = "DeepBlue"; //When $maxswitch is reached
    $minswitchtheme = "ExtraLite"; //Under $maxswitch
    $result = $db->sql_query("select Default_Theme from ".$prefix."_config");
    list($maintheme) = $db->sql_fetchrow($result);
    $onlinenum = $db->sql_numrows($db->sql_query("SELECT * FROM ".$prefix."_session"));
    if ($onlinenum > $maxswitch) {
           if ($maintheme != $maxswitchtheme) {
               $db->sql_query("UPDATE ".$prefix."_config SET Default_Theme='$maxswitchtheme'");
           }
    } elseif ($onlinenum < $maxswitch) {
           if ($maintheme != $minswitchtheme) {
               $db->sql_query("UPDATE ".$prefix."_config SET Default_Theme='$minswitchtheme'");
           }
    }

    $result = $db->sql_query("SELECT time FROM ".$prefix."_session WHERE uname='$uname'");
    $ctime = time();
    if ($uname!="") {
    $uname = substr("$uname", 0,25);
    if ($row = $db->sql_fetchrow($result)) {
   $db->sql_query("UPDATE ".$prefix."_session SET uname='$uname', time='$ctime', host_addr='$ip', guest='$guest' WHERE uname='$uname'");
    } else {
   $db->sql_query("INSERT INTO ".$prefix."_session (uname, time, host_addr, guest) VALUES ('$uname', '$ctime', '$ip', '$guest')");
    }
  }
}

I had pieced something together that worked but i'm going to use yours since you know what you're doing. icon_smile.gif

only problem with the above code... in case anybody else wants to use this...

when telli grabbed all the sessions he used $onlinenum

when he checks twice if it's above or below he used $onlinnum (with no e). otherwise this works great and i've already taken advantage of it. i'm on shared hosting and the current main theme i use is XHalo, made by the techgfx team. It's a great looking theme but is very intensive. I'm looking into changing away from it totally but for now this is great. I set it to 85 members (a little low but mine as well start saving resources early) and my site was flying with a lot of members on... without this switch my site really started to crawl with the same number.

Thanks telli, you rock!
