"Members who have read thread" question

[bazookajoe]

Is there a way to display the "members who have read this thread" in alphebetical order rather than random order?

There isn't, but you could add a plugin to sort them. Using hook showthread_whoread_list, you could use code something like this:

PHP Code:

if (!function_exists('wrt_compare_username'))
{
   function wrt_compare_username($u1, $u2) { return strcmp($u1['username'], $u2['username']); }
}

uasort($wrtlist, 'wrt_compare_username'); 


(but I haven't tested it at all).

Kevin, that in fact does correctly sort by username, however it does not ensure that all but the last name has a trailing comma.

Oh, OK, do you know how to fix it? I just typed it in without even checking to see if it had typos or anything. Feel free to post a better one.

I briefly tried earlier, but will give it a better go tonight when I am in for the night.

If you replace this ;

PHP Code:

uasort($wrtlist, 'wrt_compare_username'); 


With this ;

PHP Code:

$wrtlist[$count]['comma'] = $vbphrase['comma_space'];
uasort($wrtlist, 'wrt_compare_username');
$wrtlist[$count]['comma'] = ''; 


I *think* it will sort out the commas for you.

This is what I wound up doing, only executing the sort if the user can see the data and I wanted a case-insensitive sort as well:

PHP Code:

if ($show['wrt'])
{

    if (!function_exists('wrt_compare_username'))
    {
        function wrt_compare_username($u1, $u2) { return strcmp(strtolower($u1['username']), strtolower($u2['username'])); }
    }

    $wrtlist[count($wrtlist)]['comma'] = ',';
    usort($wrtlist, 'wrt_compare_username');
    $wrtlist[count($wrtlist)-1]['comma'] = '';
} 


I used usort() so that the keys would not be preserved, otherwise you wouldn't know which is last after the sort.

I have created a product based off of the ideas in this thread here (thank you Kevin and Paul for your contribution ):

Sort Who Read Thread Users

That product will allow you to sort the users either by userid, username, or dateline.
