[resolved] Perpetual Overdue Notifications


I am interested in a feature that would continually send email alerts for overdue tickets to the assigned staff, based on a scheduled cron job, until overdue tickets have been resolved.

Previously, I was using Lacoste's code, found here: But I noticed that after the upgrade to 1.10, this code no longer functions.

I'm wondering if anyone has created this functionality for 1.10? Maybe someone that knows a bit of php/sql could help me out to modify the code to get it to work properly?

The error received is as follows:

DB Error #1054

[SELECT ticket_id FROM xxx_ticket T1  INNER JOIN xxx_ticket_status status

( AND status.state="open")  LEFT JOIN xxx_sla T2 ON ( AND
T2.isactive=1)  WHERE isoverdue=1  ORDER BY T1.created]


Unknown column 'T2.isactive' in 'on clause'<br />
<br />

---- Backtrace ----<br />

#0 (root)/include/mysqli.php(204):
osTicket->logDBError('DB Error #1054', '[SELECT ticket_...')<br />

#1 (root)/include/class.ticket.php(3687):
db_query('SELECT ticket_i...')<br />

#2 (root)/api/notify_overdue.php(9):
Ticket::triggerOverdue()<br />

#3 {main}


  • This does not appear to be a suggestion or feedback.  Moving thread to Mods and Customizations.
  • I was able to solve the problem and create perpetual notifications successfully by changing Lacoste's custom code to the following:

    // Find overdue tickets and send notify the owners

        function triggerOverdue() {

            $sql='SELECT ticket_id FROM '.TICKET_TABLE.' T1 '

                //.' INNER JOIN '.TICKET_STATUS_TABLE.' status

                //    ON ( AND status.state="open") '

                //.' LEFT JOIN '.SLA_TABLE.' T2 ON ( AND T2.isactive=1) '

                .' WHERE isoverdue=1 '

    .' AND status_id=1'

                .' ORDER BY T1.created';

            if(($res=db_query($sql)) && db_num_rows($res)) {

                while(list($id)=db_fetch_row($res)) {

                    if( $ticket=Ticket::lookup($id) ) 



            } else {

                //TODO: Trigger escalation on already overdue tickets - make sure last overdue event > grace_period.



        static function agentActions($agent, $options=array()) {

            if (!$agent)


            require STAFFINC_DIR.'templates/tickets-actions.tmpl.php';
