(int)$_SESSION['EventID']); $db->execute(); // expired! bad javascript no workie if ( $db->resultHasRows() ) { // set sessionedit $db->setQuery('UPDATE SystemUsage SET SessionEND = NOW() WHERE EventID = ' . (int)$_SESSION['EventID']); $db->execute(); // log them out! session_destroy(); header('Location: index.php?expired=1'); exit(); } // otherwise hit the last page! $db->setQuery('UPDATE SystemUsage SET LastPage = NOW() WHERE EventID = ' . (int)$_SESSION['EventID']); $db->execute(); } else { // or.. start a new tracking session... $UserAgent = $_SERVER['HTTP_USER_AGENT']; $RemoteAddr = $_SERVER['REMOTE_ADDR']; $db->setQuery('INSERT INTO SystemUsage (UserID, SessionStart, LastPage, UserAgent, RemoteAddr)'); $db->setQuery(" VALUES (" . (int)$_SESSION['UserID'] . ", NOW(), NOW(), '$UserAgent', '$RemoteAddr')"); $db->execute(); $db->setQuery('SELECT LAST_INSERT_ID() EventID'); $row = $db->executeOrDie(); $_SESSION['EventID'] = $row->EventID; }}wc part do you think has a problem? and if ever theres nothing wrong on that part, is there anyway that i could take out the warning message??? coz as soon as i view this link http://mywebsitehere/app/buyer.php?action=notes&BuyerID=1068, it has a warning message but it display the proper results :Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/httpd/vhosts/mywebsitehere/httpdocs/lib.classes/class.MySQL.php on line 132 Link to comment https://forums.phpfreaks.com/topic/19107-more-simple-question/#findComment-82650 Share on other sites More sharing options...
Barand Posted August 30, 2006 Share Posted August 30, 2006 Extra ')' at end$db->setQuery('SELECT EventID FROM SystemUsage WHERE LastPage < DATE_SUB(NOW(), INTERVAL 15 MINUTE) AND EventID = '. (int)$_SESSION['EventID'][color=red])[/color];Also, why the (int) cast when you want to concatenate strings?
