Farewell

Great is the art of beginning, but greater is the art of ending
Henry Wadsworth Longfellow

I announce that I cease all development and activity in the programming universe indefinitely. My career has reached the turning point I was not expecting for at least another year, leaving me highly off guard and without laid-out plans for this hobby's continuity. I have begun a 5-year residency program in Neurosurgery which is clearly not compatible, time-wise, with programming.

I gave in all my passion for developing, and you gave me back your loyalty and trust, even when I did not deserve that much. Now it is the time for payback. I release all my present and past work as Open Source software, in the hope some talented developer will continue maintaining and expanding my vision of a modern, sleek forum software. The intrinsic flexibility of MyBB is the true hidden gem of an otherwise outdated codebase; I do hope the project can continue and be updated complying to the latest coding standards.

I hereby thank Euan, kawaii, andrewjs18, Ben, Matt, Omar G., effone, Eric J., Devilshakerz, Wildcard, JordanMussi and all the other team members I have had the opportunity to work with when I was a MyBB team member. I thank Tomm M, my mentor, who inspired me to pick up coding with his piece-of-art plugins. And finally, I thank all of you MyBBoost subscribers who have helped me getting through my toughest university years economically.

Yours sincerely, Filippo

Participants variable?

Hello Shade,

I'm curious how you displayed the total number of thread participants. Is there a variable in MyBB to display the number?

I'm hooking into showthread_linear with the following function:

global $mybb$db$tid$participants;

$query $db->write_query("
    SELECT DISTINCT u.uid, u.username, u.usergroup, u.displaygroup, u.avatar
    FROM " 
TABLE_PREFIX "users u
    LEFT JOIN " 
TABLE_PREFIX "posts p ON (p.uid = u.uid)
    WHERE p.tid = '
$tid'
    ORDER BY p.dateline
"
);

$plural '';
$num $db->num_rows($query);
if (
$num 1$plural 's';

$participants '<div class="participants"><h4>' $num ' participant' $plural '</h4><span>';

while (
$user $db->fetch_array($query)) {
    
$avatar "<img src='{$user['avatar']}' title='{$user['username']}' class='avatar' />";
    
$participants .= build_profile_link($avatar$user['uid']);
}

$participants .= '</span></div>'
The template is very ugly, but that just works fine in my case. I can then reference {$participants} into the showthread template. If you are wondering, I am using Hooks by frostschutz to apply this small enhancement.

In the future, quick replies will automatically add the current user avatar if not included.

Wow thank you so much for sharing the code. I'll try it out.

One other think I want to ask. Would it also be possible to get the # of participants in the forumdisplay_thread

You will need to alter the hook and the query (at least for the $tid part, which is the one specifying the thread). However, I'd go with a different approach to reduce queries to the minimum. I might write down a tutorial for both cases as soon as I have some spare time.

Very nice Shade, it worked perfectly. Thank you so much for sharing that.

Shade would there be a way to limit the amount of avatars to output to around 10. I have several threads on my forum with over 600 participants and with all avatars displaying it would slow the load time. Thank you.

Add a LIMIT condition to the query, specifying how many elements should be returned.

$query $db->write_query("
    SELECT DISTINCT u.uid, u.username, u.usergroup, u.displaygroup, u.avatar
    FROM " 
TABLE_PREFIX "users u
    LEFT JOIN " 
TABLE_PREFIX "posts p ON (p.uid = u.uid)
    WHERE p.tid = '
$tid'
    ORDER BY p.dateline
    LIMIT 10
"
); 
If you want to show the real number of participants alongside the last 10 participants, things are a bit more complex as you will need to write down a separate COUNT query.

Thank you. That worked well. Here is the code I'm using if anyone wants to limit the avatars.

        global $mybb$db$tid$participants_num;

$query $db->write_query("
    SELECT DISTINCT u.uid, u.username, u.usergroup, u.displaygroup, u.avatar
    FROM " 
TABLE_PREFIX "users u
    LEFT JOIN " 
TABLE_PREFIX "posts p ON (p.uid = u.uid)
    WHERE p.tid = '
$tid'
    ORDER BY p.dateline
"
); 

$plural '';
$num $db->num_rows($query);
if (
$num 1$plural 's';

$participants_num '<div class="participants">' $num ' participant' $plural '</div>';


        global 
$mybb$db$tid$participants;

$query $db->write_query("
    SELECT DISTINCT u.uid, u.username, u.usergroup, u.displaygroup, u.avatar
    FROM " 
TABLE_PREFIX "users u
    LEFT JOIN " 
TABLE_PREFIX "posts p ON (p.uid = u.uid)
    WHERE p.tid = '
$tid'
    ORDER BY p.dateline
    LIMIT 10
"
); 

$participants '<div class="participants"><span>';

while (
$user $db->fetch_array($query)) {
    
$avatar "<img src='{$user['avatar']}' title='{$user['username']}' class='avatar'/>";
    
$participants .= build_profile_link($avatar$user['uid']);
}

$participants .= '</span></div>'
    } 
Use {$participants} for avatars and {$participants_num} for number of participants.

I'd rather do:

$query $db->simple_select('posts''COUNT(DISTINCT(uid)) AS count''tid = ' $tid);
$num $db->fetch_field($query'count'); 
Which is faster as you don't need to join multiple tables. I'd also subtract the 10 participants to show the last 10 with the avatar, and a label with "... and X more" or something like this.

global $mybb, $db, $tid, $participants;

$query = $db->write_query("
   SELECT DISTINCT u.uid, u.username, u.usergroup, u.displaygroup, u.avatar
   FROM " . TABLE_PREFIX . "users u
   LEFT JOIN " . TABLE_PREFIX . "posts p ON (p.uid = u.uid)
   WHERE p.tid = '$tid'
   ORDER BY p.dateline
");

$plural = '';
$num = $db->num_rows($query);
if ($num > 1) $plural = 's';

$participants = '<div class="participants"><h5>' . $num . ' participant' . $plural . '</h5><span>';

while ($user = $db->fetch_array($query)) {
    $avatar = "<img src='{$user['avatar']}' title='{$user['username']}' class='avatar'/>";
    $participants .= build_profile_link($avatar, $user['uid']);
}



$participants .= '</span></div>';
I am using this, but once there are 30 participants, it gets over the "new reply" button. I don't like to limit, but i want to show all participants, whether the number is high or not.

How could i make it, so if the participants numbers hit 29, it breaks the line? See my screenshots:

How it looks good until 29:

How it should continue after 29, number 30, 31, etc. should continue below the 1st one, without making a space line to the new reply button:

Any idea anyone?
