LON-CAPA implements its -own messaging system, rather then building on top of email, because of -the features LON-CAPA messages can offer that conventional e-mail can -not: - -=over 4 - -=item * B: A message the recipient B -acknowlegde receipt of before they are allowed to continue using the -system, preventing a user from claiming they never got a message - -=item * B: LON-CAPA can reliably send reciepts informing the -sender that it has been read; again, useful for preventing students -from claiming they did not see a message. (While conventional e-mail -has some reciept support, it's sporadic, e-mail client-specific, and -generally the receiver can opt to not send one, making it useless in -this case.) - -=item * B: LON-CAPA knows about the sender, such as where -they are in a course. When a student mails an instructor asking for -help on the problem, the instructor receives not just the student's -question, but all submissions the student has made up to that point, -the user's rendering of the problem, and the complete view the student -saw of the resource, including discussion up to that point. Finally, -the instructor is reading all of this inside of LON-CAPA, not their -email program, so they have full access to LON-CAPA's grading -interface, or other features they may wish to use in response to the -student's query. - -=item * B: LON-CAPA can block display of e-mails that are -sent to a student during an online exam. A course coordinator or -instructor can set an open and close date/time for scheduled online -exams in a course. If a user uses the LON-CAPA internal messaging -system to display e-mails during the scheduled blocking event, -display of all e-mail sent during the blocking period will be -suppressed, and a message of explanation, including details of the -currently active blocking periods will be displayed instead. A user -who has a course coordinator or instructor role in a course will be -unaffected by any blocking periods for the course, unless the user -also has a student role in the course, AND has selected the student role. - -=back - -Users can ask LON-CAPA to forward messages to conventional e-mail -addresses on their B screen, but generally, LON-CAPA messages -are much more useful than traditional email can be made to be, even -with HTML support. - -Right now, this document will cover just how to send a message, since -it is likely you will not need to programmatically read messages, -since lonmsg already implements that functionality. - -The routines used to package messages and unpackage messages are not -only used by lonmsg when creating/extracting messages for LON-CAPA's -internal messaging system, but also by lonnotify.pm which is available -for use by Domain Coordinators to broadcast standard e-mail to specified -users in their domain. The XML packaging used in the two cases is very -similar. The differences are the use of $uname and -$udom in stored internal messages, compared -with $email in stored -Domain Coordinator e-mail for the storage of information about -recipients of the message/e-mail. - -=head1 FUNCTIONS - -=over 4 - -=cut - use strict; use Apache::lonnet; -use vars qw($msgcount); use HTML::TokeParser(); -use Apache::Constants qw(:common); -use Apache::loncommon(); -use Apache::lontexconvert(); -use HTML::Entities(); -use Mail::Send; use Apache::lonlocal; -use Apache::loncommunicate; -use Apache::lonfeedback; -use Apache::lonrss(); - -# Querystring component with sorting type -my $sqs; -my $startdis; -my $interdis; +use Mail::Send; +use LONCAPA qw(:DEFAULT :match); + +{ + my $uniq; + sub get_uniq { + $uniq++; + return $uniq; + } +} # ===================================================================== Package sub packagemsg { my ($subject,$message,$citation,$baseurl,$attachmenturl, - $recuser,$recdomain,$msgid,$type,$crsmsgid)=@_; + $recuser,$recdomain,$msgid,$type,$crsmsgid,$symb,$error)=@_; $message =&HTML::Entities::encode($message,'<>&"'); $citation=&HTML::Entities::encode($citation,'<>&"'); $subject =&HTML::Entities::encode($subject,'<>&"'); @@ -150,13 +60,13 @@ sub packagemsg { my $course_context; if (defined($env{'form.replyid'})) { my ($sendtime,$shortsubj,$fromname,$fromdomain,$count,$origcid)= - split(/\:/,&Apache::lonnet::unescape($env{'form.replyid'})); + split(/\:/,&unescape($env{'form.replyid'})); $course_context = $origcid; } foreach my $key (keys(%env)) { if ($key=~/^form\.(rep)?rec\_(.*)$/) { my ($sendtime,$shortsubj,$fromname,$fromdomain,$count,$origcid) = - split(/\:/,&Apache::lonnet::unescape($2)); + split(/\:/,&unescape($2)); $course_context = $origcid; last; } @@ -165,10 +75,10 @@ sub packagemsg { $course_context = $env{'request.course.id'}; } my $now=time; - $msgcount++; + my $msgcount = &get_uniq(); unless(defined($msgid)) { $msgid = &buildmsgid($now,$subject,$env{'user.name'},$env{'user.domain'}, - $msgcount,$course_context,$$); + $msgcount,$course_context,$symb,$error,$$); } my $result = ''.$env{'user.name'}.''.
