33 This script prepares pre-due and item due reminders to be sent to
34 patrons. It queues them in the message queue, which is processed by
35 the process_message_queue.pl cronjob. The type and timing of the
36 messages can be configured by the patrons in their "My Alerts" tab in

79 Prints the manual page and exits.
83 Verbose. Without this flag set, only fatal errors are reported.
87 Do not send any email. Advanced or due notices that would have been sent to

92 Defines the maximum number of days in advance to send advance notices.

101 comma separated list of fields that get substituted into templates in
102 places of the E<lt>E<lt>items.contentE<gt>E<gt> placeholder. This
103 defaults to due date,title,author,barcode
105 Other possible values come from fields in the biblios, items and
112 This script is designed to alert patrons when items are due, or coming due
116 This script pays attention to the advanced notice configuration
117 performed by borrowers in the OPAC, or by staff in the patron detail page of the intranet. The content of the messages is configured in Tools -> Notices and slips. Advanced notices use the PREDUE template, due notices use DUE. More information about the use of this
118 section of Koha is available in the Koha manual.
120 =head2 Outgoing emails
122 Typically, messages are prepared for each patron with due
123 items, and who have selected (or the library has elected for them) Advance or Due notices.
125 These emails are staged in the outgoing message queue, as are messages
126 produced by other features of Koha. This message queue must be
127 processed regularly by the
128 F<misc/cronjobs/process_message_queue.pl> program.
130 In the event that the C<-n> flag is passed to this program, no emails
131 are sent. Instead, messages are sent on standard output from this
132 program. They may be redirected to a file if desired.
136 Templates can contain variables enclosed in double angle brackets like
137 E<lt>E<lt>thisE<gt>E<gt>. Those variables will be replaced with values
138 specific to the overdue items or relevant patron. Available variables
143 =item E<lt>E<lt>items.contentE<gt>E<gt>
145 one line for each item, each line containing a tab separated list of
146 title, author, barcode, issuedate
148 =item E<lt>E<lt>borrowers.*E<gt>E<gt>
150 any field from the borrowers table
152 =item E<lt>E<lt>branches.*E<gt>E<gt>
154 any field from the branches table
160 The F<misc/cronjobs/overdue_notices.pl> program allows you to send
161 messages to patrons when their messages are overdue.
