22 advance_notices.pl - prepare messages to be sent to patrons for nearly due, or due, items
27 [ -n ][ -m <number of days> ][ --itemscontent <comma separated field list> ][ -c ]
31 This script prepares pre-due and item due reminders to be sent to
32 patrons. It queues them in the message queue, which is processed by
33 the process_message_queue.pl cronjob. The type and timing of the
34 messages can be configured by the patrons in their "My Alerts" tab in
41 use Getopt::Long qw( GetOptions );
42 use Pod::Usage qw( pod2usage );
43 use Koha::Script -cron;
47 use C4::Members::Messaging;
48 use C4::Log qw( cronlogaction );
59 Print a brief help message and exits.
63 Prints the manual page and exits.
67 Verbose. Without this flag set, only fatal errors are reported.
71 Do not send any email. Advanced or due notices that would have been sent to
72 the patrons are printed to standard out.
76 Defines the maximum number of days in advance to send advance notices.
80 Confirm flag: Add this option. The script will only print a usage
83 =item B<--itemscontent>
85 comma separated list of fields that get substituted into templates in
86 places of the E<lt>E<lt>items.contentE<gt>E<gt> placeholder. This
87 defaults to date_due,title,author,barcode
89 Other possible values come from fields in the biblios, items and
92 =item B<--digest-per-branch>
94 Flag to indicate that generation of message digests should be
95 performed separately for each branch.
97 A patron could potentially have loans at several different branches
98 There is no natural branch to set as the sender on the aggregated
99 message in this situation so the default behavior is to use the
100 borrowers home branch. This could surprise to the borrower when
101 message sender is a library where they have not borrowed anything.
103 Enabling this flag ensures that the issuing library is the sender of
104 the digested message. It has no effect unless the borrower has
105 chosen 'Digests only' on the advance messages.
109 select notices for one specific library. Use the value in the
110 branches.branchcode table. This option can be repeated in order
111 to select notices for a group of libraries.
113 =item B<--frombranch>
115 Set the from address for the notice to one of 'item-homebranch' or 'item-issuebranch'.
117 Defaults to 'item-issuebranch'
123 This script pays attention to the advanced notice configuration
124 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
125 section of Koha is available in the Koha manual.
127 =head2 Outgoing emails
129 Typically, messages are prepared for each patron with due
130 items, and who have selected (or the library has elected for them) Advance or Due notices.
132 These emails are staged in the outgoing message queue, as are messages
133 produced by other features of Koha. This message queue must be
134 processed regularly by the
135 F<misc/cronjobs/process_message_queue.pl> program.
137 In the event that the C<-n> flag is passed to this program, no emails
138 are sent. Instead, messages are sent on standard output from this
139 program. They may be redirected to a file if desired.
143 Templates can contain variables enclosed in double angle brackets like
144 E<lt>E<lt>thisE<gt>E<gt>. Those variables will be replaced with values
145 specific to the overdue items or relevant patron. Available variables
150 =item E<lt>E<lt>items.contentE<gt>E<gt>
152 one line for each item, each line containing a tab separated list of
153 date due, title, author, barcode
155 =item E<lt>E<lt>borrowers.*E<gt>E<gt>
157 any field from the borrowers table
159 =item E<lt>E<lt>branches.*E<gt>E<gt>
161 any field from the branches table
167 The F<misc/cronjobs/overdue_notices.pl> program allows you to send
168 messages to patrons when their messages are overdue.
