  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.

  64 =head1 SYNOPSIS

  66 advance_notices.pl
  67   [ -n ][ -m <number of days> ][ --itemscontent <comma separated field list> ][ -c ]
  68
  69 =head1 OPTIONS
  70
  71 =over 8
  72
  73 =item B<--help>
  74
  75 Print a brief help message and exits.
  76
  77 =item B<--man>
  78
  79 Prints the manual page and exits.
  80
  81 =item B<-v>
  82
  83 Verbose. Without this flag set, only fatal errors are reported.
  84
  85 =item B<-n>
  86
  87 Do not send any email. Advanced or due notices that would have been sent to
  88 the patrons are printed to standard out.
  89
  90 =item B<-m>
  91
  92 Defines the maximum number of days in advance to send advance notices.
  93
  94 =item B<-c>
  95
  96 Confirm flag: Add this option. The script will only print a usage
  97 statement otherwise.
  98
  99 =item B<--itemscontent>
 100
 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
 104
 105 Other possible values come from fields in the biblios, items and
 106 issues tables.
 107
 108 =back
 109
 110 =head1 DESCRIPTION
 111
 112 This script is designed to alert patrons when items are due, or coming due
 113
 114 =head2 Configuration
 115
 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.
 119
 120 =head2 Outgoing emails
 121
 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.
 124
 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.
 129
 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.
 133
 134 =head2 Templates
 135
 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
 139 are:
 140
 141 =over
 142
 143 =item E<lt>E<lt>items.contentE<gt>E<gt>
 144
 145 one line for each item, each line containing a tab separated list of
 146 title, author, barcode, issuedate
 147
 148 =item E<lt>E<lt>borrowers.*E<gt>E<gt>
 149
 150 any field from the borrowers table
 151
 152 =item E<lt>E<lt>branches.*E<gt>E<gt>
 153
 154 any field from the branches table
 155
 156 =back
 157
 158 =head1 SEE ALSO
 159
 160 The F<misc/cronjobs/overdue_notices.pl> program allows you to send
 161 messages to patrons when their messages are overdue.
