You use the advanced theme for that. File: qa-theme.php
There you insert:
function sidepanel() {
// requires CHAT plugin
// output Chat-Button only on startpage (main page) + questions list page + liveticker
if ($this->template=='qa' || $this->template=='questions' || $this->template=='question' || $this->request=='liveticker' ) {
// get number of online users
$countActiveUsers = qa_db_read_one_value( qa_db_query_sub( 'SELECT COUNT(*)
FROM ^users u, ^chat_users c
WHERE u.userid=c.userid AND c.lastpolled > DATE_SUB(NOW(), INTERVAL 1 MINUTE)' ) );
// logged in see directly who is online
$onlineUsernames = '';
if(qa_is_logged_in()) {
$queryUserNames = qa_db_query_sub( 'SELECT u.userid, u.handle AS username
FROM ^users u, ^chat_users c
WHERE u.userid=c.userid AND c.lastpolled > DATE_SUB(NOW(), INTERVAL 1 MINUTE)
ORDER BY u.handle');
while ( ($row = qa_db_read_one_assoc($queryUserNames,true)) !== null ) {
// first
if($onlineUsernames=='') {
$onlineUsernames .= $row['username']; // 'Es unterhalten sich:<br />'
}
else {
$onlineUsernames .= ', '.$row['username'];
}
}
$onlineUsernames = 'title="Online: '.$onlineUsernames.'"';
}
else {
$onlineUsernames = 'title="Only registered users can join the chat"';
}
if($countActiveUsers>0) {
$this->output('<a '.$onlineUsernames.' class="btnyellow oranged" style="margin-top:10px;" href="'.qa_opt('site_url').'chat" target="_blank">Chat ('.$countActiveUsers.')</a>');
}
else {
$this->output('<a class="btnyellow oranged" style="margin-top:10px;" href="'.qa_opt('site_url').'chat" target="_blank">Community-Chat</a>');
}
}
qa_html_theme_base::sidepanel();
}
