Suki:
So, the chat count do work? if so, there should be easy to include your image, we just need a check on that var if it has 1 or more as it's value.

dooie:
Sorry Suki,

No the Chat count does not work, that is the issue I have.
I can not find where $context['num_chat'] is located in any of the files? Could this be the missing variable?
I found all the other variables in Modifications.english.php but I can not find ['num_chat'] anywhere.

Here are the FlashChat variables in Modifications.english.php

--- Code: ---// --- Begin FlashChat Integration ---
$txt['fc_chat'] = 'Chat';
$txt['fc_flashchat'] = 'FlashChat';
$txt['fc_flashchat_settings'] = 'FlashChat Integration Settings';
$txt['fc_in_chat'] = 'in Chat';
$txt['fc_not_found'] = 'FlashChat does not appear to be installed!';
$txt['fc_no_guests'] = 'Sorry, guests aren\'t allowed to use the chat!';
$txt['fc_private_room'] = 'private room';
$txt['fc_users_online'] = 'Users currently in chat';
// For 'Who's Online' page
$txt['whoall_chat'] = 'In the <a href="' . $boardurl . '?action=chat">Chatroom</a>';

// Settings for admin panel
$txt['fc_height2'] = 'Height';
$txt['fc_config'] = 'FlashChat Configuration';
$txt['fc_inForum'] = 'Display chat window "inside" forum?';
$txt['fc_newWindow'] = 'Open chat in new window?';
$txt['fc_showUsers'] = 'Display Users in Chat at top of forum?';
$txt['fc_showUserCount'] = 'Show number of users on Chat button?';
$txt['fc_size_desc'] = 'The height and width must me in px (eg. 600 for 600 pixels)! If no value is set it will default to 80% x 400px';
$txt['fc_width'] = 'Width';
// --- End FlashChat Integration ---
--- End code ---

The Chat button menu code in Subs.php is;

--- Code: ---//Start FlashChat integration
'chat' => array(
'title' => $txt['fc_chat'],
'href' => $scripturl . '?action=chat"', (!empty($modSettings['fc_newWindow']) ? ' target="_blank"' : ''), '>', $txt['fc_chat'], (!empty($modSettings['fc_showUserCount']) && !empty($context['num_chat']) ? ' [' . $context['num_chat'] . ' ' . ($context['num_chat'] == 1 ? $txt['user'] : $txt['users']) . ']' : ''),
'show' => !$user_info['is_guest'],
'sub_buttons' => array(
),
),
//End FlashChat integration
--- End code ---

The Chat count and Flashing icon worked in the previous version of SMF 1.1.1 that I was running with this code;

--- Code: --- // FlashChat!
global $modSettings;
$flashy_image = '<img src="{url_to_image}" alt="Flashy" border="0" />';
if ($context['user']['is_logged'])
echo ($current_action == 'chat' || $context['browser']['is_ie4']) ? '<td class="maintab_active_' . $first . '"> </td>' : '' , '
<td valign="top" class="maintab_' , $current_action == 'chat' ? 'active_back' : 'back' , '">
<a href="', $scripturl, '?action=chat"', (!empty($modSettings['fc_newWindow']) ? ' target="_blank"' : ''), '>', $txt['fc_chat'], (!empty($modSettings['fc_showUserCount']) && !empty($context['num_chat']) ? ' [' . $context['num_chat'] . ' ' . ($context['num_chat'] == 1 ? $txt['user'] : $txt['users']) . '] ' . $flashy_image : ''), '</a>
</td>' , $current_action == 'chat' ? '<td class="maintab_active_' . $last . '"> </td>' : '';
--- End code ---

With the changes in SMF 2.0.2, I am totally lost?
Any idea's?

Cheers.

Suki:
That var is defined on the very same file via a query:

--- Code: ---// --- Begin FlashChat Integration ---
// Only bother grabbing the data if we need it (ie. we're on the board
// index, or the information will be shown at the top of the forum).
// !!! $modSettings['fc_showUserCount'] just needs the count, not the whole query!
if (!empty($modSettings['fc_showUsers']) || !empty($modSettings['fc_showUserCount']) || (empty($context['current_action']) || $context['current_action'] == 'boardindex' || $context['current_action'] == 'forum'))

global $boarddir, $db_prefix, $db_name;
global $request, $fc_prefix, $context, $smcFunc, $link, $scripturl, $row;
// Get the FlashChat database config (for the prefix)
include($boarddir . '/chat/inc/config.srv.php');
// Get the proper database prefix (including database name)
$fc_prefix = is_numeric(substr($GLOBALS['fc_config']['db']['pref'], 0, 1)) ? $db_name . '.' . $GLOBALS['fc_config']['db']['pref'] : '`' . $db_name . '`.' . $GLOBALS['fc_config']['db']['pref'];

// Load all the users currently in the chat
$request = $smcFunc['db_query']('' , '

LEFT JOIN {$fc_prefix}rooms AS fr ON (fc.roomid = fr.id)
WHERE fc.userid IS NOT NULL
AND mem.id_member != 0
ORDER BY mem.real_name ASC');

$context['users_chat'] = array();
$context['list_users_chat'] = array();
$context['num_chat'] = $smcFunc['db_num_rows']($request);

// Loop through all users in chat
while ($row = $smcFunc['db_fetch_assoc']($request))
{
// Does their membergroup have a colour?
if (!empty($row['online_color']))
$link = '<a href="' . $scripturl . '?action=profile;u=' . $row['userid'] . '" style="color: ' . $row['online_color'] . ';">' . $row['real_name'] . '</a>';
else
$link = '<a href="' . $scripturl . '?action=profile;u=' . $row['userid'] . '">' . $row['real_name'] . '</a>';

// Add them to the 'Users Online' list
$context['users_chat'][$row['member_name']] = array(
'id' => $row['userid'],
'username' => $row['member_name'],
'name' => $row['real_name'],
'group' => $row['id_group'],
'href' => $scripturl . '?action=profile;u=' . $row['userid'],
'link' => $link,
'chat' => array(
'color' => $row['color'],
'lang' => $row['lang'],
'room' => array(
'id' => $row['roomid'],
'name' => $row['roomName'],
'public' => ($row['ispublic'] == 'y' ? true : false),
),
),
);

$context['list_users_chat'][$row['member_name']] = $link . ' (' . ($row['ispublic'] != 'y' ? $txt['fc_private_room'] : $row['roomName']) . ')';

// Groups online
if (!isset($context['online_groups'][$row['id_group']]))
$context['online_groups'][$row['id_group']] = array(
'id' => $row['id_group'],

);
}
$smcFunc['db_free_result'];
}
// --- End FlashChat Integration ---

--- End code ---

I don't know how that mod works, apparently it only performs the query if you are on the BoardIndex with no action.

Is there any error on your error log?

dooie:
I just did a test in Chat with two users in chat and no errors in the log.

Cheers.

Suki:
Are you viewing the chat box on the BoardIndex?

find this line:

if (!empty($modSettings['fc_showUsers']) || !empty($modSettings['fc_showUserCount']) || (empty($context['current_action']) || $context['current_action'] == 'boardindex' || $context['current_action'] == 'forum'))

and change it with:

// if (!empty($modSettings['fc_showUsers']) || !empty($modSettings['fc_showUserCount']) || (empty($context['current_action']) || $context['current_action'] == 'boardindex' || $context['current_action'] == 'forum'))
