hi,
this is only a very fast response :))
is solved this kind of problem like that:
(quick solution for a chatboard - user cannot login for xxxxx seconds -
maxidletime)
/***********two functions:******************/
function logoutMsgBoardUser($UserName)
global $MessageBoardTable,$SiteID;
$DB=new connectDB();
$actDate= date("Y-m-d H:i:s");
$newMessage=addslashes($UserName)." logged out.";
$host="System";
$Query="update ".$MessageBoardTable."
set logged_out='1' where
name='".addslashes($UserName)."'
and site_id='".$SiteID."'
and logged_out!='1'
";
$DB->Query($Query);
$Query="insert into ".$MessageBoardTable."
(site_id,name,msg,created,host,archiv,aktiv,logged_out)
values
'".$SiteID."',
'',
'".$newMessage."',
'".$actDate."',
'".$host."',
'0',
'1',
'1'
)";
$DB->Query($Query);
}
function getMsgBoardUserIdleTime($UserName)
global $MessageBoardTable,$SiteID;
$DB=new ConnectDB();
$Query="select created from ".$MessageBoardTable." where
site_id='".$SiteID."' and logged_out='0' and
name='".addslashes($UserName)."' and aktiv='1' order by id desc limit 1";
$DB->Query($Query);
if ($DB->next_record())
$lastUserPost=$DB->Record['created'];
$actDate= date("Y-m-d H:i:s");
$Result=strtotime(date ($actDate))-strtotime($lastUserPost);
} else
$Result=0;
}
return $Result;
}
/***************and the code... i think thats all**************/
if ($msglogin=='1') {
$newMessage=" <b>entered the Messageboard</b>";
if (getMsgBoardUserIdleTime($MName) >0) {
echo "Eine User mit diesem Namen ist bereits Online, bitte waehle einen
anderen...";
$logged_out=true;
$MName="";
}
}
if (isset($MName) && $MName!="") {
$MyIdleTime=getMsgBoardUserIdleTime($MName);
if ($MyIdleTime > $MaxIdleTime) {
logoutMsgBoardUser($MName);
$logged_out=true;
$MName="";
echo " logged out by system after ".$MyIdleTime." seconds without saying
anything ;)";
}
}
