  22 advance_notices.pl - cron script to put item due reminders into message queue
  23
  24 =head1 SYNOPSIS
  25
  26 ./advance_notices.pl -c
  27
  28 or, in crontab:
  29 0 1 * * * advance_notices.pl -c
  30
  31 =head1 DESCRIPTION
  32
  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
  37 the OPAC.

  67
  68 =head1 SYNOPSIS

  70 advance_notices.pl
  71   [ -n ][ -m <number of days> ][ --itemscontent <comma separated field list> ][ -c ]
  72
  73 =head1 OPTIONS
  74
  75 =over 8
  76
  77 =item B<--help>
  78
  79 Print a brief help message and exits.
  80
  81 =item B<--man>
  82
  83 Prints the manual page and exits.
  84
  85 =item B<-v>
  86
  87 Verbose. Without this flag set, only fatal errors are reported.
  88
  89 =item B<-n>
  90
  91 Do not send any email. Advanced or due notices that would have been sent to
  92 the patrons are printed to standard out.
  93
  94 =item B<-m>
  95
  96 Defines the maximum number of days in advance to send advance notices.
  97
  98 =item B<-c>
  99
 100 Confirm flag: Add this option. The script will only print a usage
 101 statement otherwise.
 102
 103 =item B<--itemscontent>
 104
 105 comma separated list of fields that get substituted into templates in
 106 places of the E<lt>E<lt>items.contentE<gt>E<gt> placeholder. This
 107 defaults to date_due,title,author,barcode
 108
 109 Other possible values come from fields in the biblios, items and
 110 issues tables.
 111
 112 =back
 113
 114 =head1 DESCRIPTION
 115
 116 This script is designed to alert patrons when items are due, or coming due
 117
 118 =head2 Configuration
 119
 120 This script pays attention to the advanced notice configuration
 121 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
 122 section of Koha is available in the Koha manual.
 123
 124 =head2 Outgoing emails
 125
 126 Typically, messages are prepared for each patron with due
 127 items, and who have selected (or the library has elected for them) Advance or Due notices.
 128
 129 These emails are staged in the outgoing message queue, as are messages
 130 produced by other features of Koha. This message queue must be
 131 processed regularly by the
 132 F<misc/cronjobs/process_message_queue.pl> program.
 133
 134 In the event that the C<-n> flag is passed to this program, no emails
 135 are sent. Instead, messages are sent on standard output from this
 136 program. They may be redirected to a file if desired.
 137
 138 =head2 Templates
 139
 140 Templates can contain variables enclosed in double angle brackets like
 141 E<lt>E<lt>thisE<gt>E<gt>. Those variables will be replaced with values
 142 specific to the overdue items or relevant patron. Available variables
 143 are:
 144
 145 =over
 146
 147 =item E<lt>E<lt>items.contentE<gt>E<gt>
 148
 149 one line for each item, each line containing a tab separated list of
 150 date due, title, author, barcode
 151
 152 =item E<lt>E<lt>borrowers.*E<gt>E<gt>
 153
 154 any field from the borrowers table
 155
 156 =item E<lt>E<lt>branches.*E<gt>E<gt>
 157
 158 any field from the branches table
 159
 160 =back
 161
 162 =head1 SEE ALSO
 163
 164 The F<misc/cronjobs/overdue_notices.pl> program allows you to send
 165 messages to patrons when their messages are overdue.
