View source for Silent Resolve (MuteResolve ReRedux)

I couldn't get either the [[MuteResolve]] or [[MuteResolve Redux]] solutions to work, so here's mine. It seems to work well and is simpler. Tested with RT 4.0.2, but sould probably work with 3.x versions as well.

#Create a Ticket Custom Field called Silent Resolve. ('''Tools->Configuration->Custom Fields->Create''') Name: SilentResolve<br />Type: Select one value<br />Render Type: List (you may have to save it before this option appears)<br />Values: Sort=0, Name='Yes'
#Select it under '''Tools->Configuration->Global->Custom Fields->Tickets'''. (Why the two-step process beats me, especially when they have an Enabled checkbox on the field definition in step 1)
#Create a new Global Template (Your mail server should route nobody@ to /dev/null)<br />Name: Resolved (Check Silent)<br />Type: Perl<br />Content:<br />
 <nowiki>
     { 
     $nobody = 'nobody@localhost';
     if ($Ticket->FirstCustomFieldValue('SilentResolve') eq 'Yes') {
     "To: $nobody\nCc: $nobody\nBcc: $nobody\n";
     } else {
     ;
     }
     }Subject: Resolved: {$Ticket->Subject} 
    
     According to our records, your request has been resolved. If you have any
     further questions or concerns, please respond to this message.
     </nowiki>
: Note that the "}Subject" is not a typo. You need it like that to make sure all that stuff is part of the e-mail header.
#Set the "On Resolve Notify Requestors" scrip to use this template.
#Create a new scrip. ('''Tools->Configuration->Global->Scrips->Select''')<br />Name: Unset Silent Resolve<br />Condition: On Reopen<br />Action: User Defined<br />Template: Global template: Blank<br />Stage: TransactionCreate<br />Custom Condition:<br />
 <nowiki> return ($self->TicketObj->FirstCustomFieldValue('SilentResolve') eq 'Yes' ? 1 : 0);
 </nowiki>
<br />Custom action preparation code:<br />
 <nowiki>
  $self->TicketObj->DeleteCustomFieldValue( Field => 'SilentResolve', Value => 'Yes');
  $RT::Logger->info("Silent Resolve unset on Reopen of ticket ".$self->TicketObj->id);
  return 1;
