  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
  65 =head1 SYNOPSIS
  66
  67 advance_notices.pl
  68   [ -n ][ -m <number of days> ][ --itemscontent <comma separated field list> ][ -c ]
  69
  70 =head1 OPTIONS
  71
  72 =over 8
  73
  74 =item B<--help>
  75
  76 Print a brief help message and exits.
  77
  78 =item B<--man>
  79
  80 Prints the manual page and exits.
  81
  82 =item B<-v>
  83
  84 Verbose. Without this flag set, only fatal errors are reported.
  85
  86 =item B<-n>
  87
  88 Do not send any email. Advanced or due notices that would have been sent to
  89 the patrons are printed to standard out.
  90
  91 =item B<-m>
  92
  93 Defines the maximum number of days in advance to send advance notices.
  94
  95 =item B<-c>
  96
  97 Confirm flag: Add this option. The script will only print a usage
  98 statement otherwise.
  99
 100 =item B<--itemscontent>
 101
 102 comma separated list of fields that get substituted into templates in
 103 places of the E<lt>E<lt>items.contentE<gt>E<gt> placeholder. This
 104 defaults to due date,title,author,barcode
 105
 106 Other possible values come from fields in the biblios, items and
 107 issues tables.
 108
 109 =back
 110
 111 =head1 DESCRIPTION
 112
 113 This script is designed to alert patrons when items are due, or coming due
 114
 115 =head2 Configuration
 116
 117 This script pays attention to the advanced notice configuration
 118 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
 119 section of Koha is available in the Koha manual.
 120
 121 =head2 Outgoing emails
 122
 123 Typically, messages are prepared for each patron with due
 124 items, and who have selected (or the library has elected for them) Advance or Due notices.
 125
 126 These emails are staged in the outgoing message queue, as are messages
 127 produced by other features of Koha. This message queue must be
 128 processed regularly by the
 129 F<misc/cronjobs/process_message_queue.pl> program.
 130
 131 In the event that the C<-n> flag is passed to this program, no emails
 132 are sent. Instead, messages are sent on standard output from this
 133 program. They may be redirected to a file if desired.
 134
 135 =head2 Templates
 136
 137 Templates can contain variables enclosed in double angle brackets like
 138 E<lt>E<lt>thisE<gt>E<gt>. Those variables will be replaced with values
 139 specific to the overdue items or relevant patron. Available variables
 140 are:
 141
 142 =over
 143
 144 =item E<lt>E<lt>items.contentE<gt>E<gt>
 145
 146 one line for each item, each line containing a tab separated list of
 147 title, author, barcode, issuedate
 148
 149 =item E<lt>E<lt>borrowers.*E<gt>E<gt>
 150
 151 any field from the borrowers table
 152
 153 =item E<lt>E<lt>branches.*E<gt>E<gt>
 154
 155 any field from the branches table
 156
 157 =back
 158
 159 =head1 SEE ALSO
 160
 161 The F<misc/cronjobs/overdue_notices.pl> program allows you to send
 162 messages to patrons when their messages are overdue.
