Can someone please help me with this block code? I want to truncate or limit the length of long usernames that push my block out of size. Here are the lines of code I am currently using:

$lasturow = $db->sql_fetchrow($db->sql_query("SELECT username FROM $user_prefix"._users." ORDER BY user_id DESC LIMIT 0,1"));
$lastuser = $lasturow['username'];
$numrows = $db->sql_numrows($db->sql_query("SELECT user_id FROM $user_prefix"._users.""));

$result = $db->sql_query("SELECT uname, guest FROM $prefix"._session." WHERE guest='0'");
$member_online_num = $db->sql_numrows($result);
$who_online_now = "";
$i = 1;
while ($session = $db->sql_fetchrow($result)) {
    if (isset($session["guest"]) and $session["guest"] == 0) {
        if ($i < 10) {
            $who_online_now .= " ;; ;;0$i: ;;$session[uname]<br>\n";
        } else {
            $who_online_now .= " ;; ;;$i: ;;$session[uname]<br>\n";
        }
        $who_online_now .= ($i != $member_online_num ? "  " : "");
        $i++;
    }
}

that looks like the wrong code

open modules/Your_Account/index.php
search for instances of:
maxlength=\"25\"

and replace the 25 with the number you like

i suggest 16
be careful if you have registered users with longer names already, they may not be able to log in after.
there are a few instances, likely, one is a couple lines after this bit:
"_REGNEWUSER" thats the signup one, which is likely the one you care about.
if you already have users with longer names, i guess you could email them, or warn them that you will be changing their name, then you can edit their account and do any other instances.

if you just want it to display the first 16 chars of the name, no matter how long, then i'm not sure, and i'm totally wasting my time replying!

lol

$output = substr($input, 0, 16)

of course change $input to the value you want to trim down and 16 to the # of characters you want to display.

Thanks for the replies. I have already limited the new user registrations after I discovered the problem with this template block width. I do not want to ask all the users to modify their usernames unless there is no other option.

Regarding the reply below, where do I add this in the code? I tried a few places but must be doing it wrong.

Thank you for the assistance!

$lasturow = $db->sql_fetchrow($db->sql_query("SELECT username FROM $user_prefix"._users." ORDER BY user_id DESC LIMIT 0,1"));
$lastuser = $lasturow['username'];
$numrows = $db->sql_numrows($db->sql_query("SELECT user_id FROM $user_prefix"._users.""));

$result = $db->sql_query("SELECT uname, guest FROM $prefix"._session." WHERE guest='0'");
$member_online_num = $db->sql_numrows($result);
$who_online_now = "";
$i = 1;
while ($session = $db->sql_fetchrow($result)) {
    if (isset($session["guest"]) and $session["guest"] == 0) {
        if ($i < 10) {
            $who_online_now .= "0$i:".substr("$session[uname]", 0, 16)."<br>\n";
        } else {
            $who_online_now .= " $i:".substr("$session[uname]", 0, 16)."<br>\n";
        }
        $who_online_now .= ($i != $member_online_num ? "  " : "");
        $i++;
    }
}


Try that out.
