72 Verbose. Without this flag set, only fatal errors are reported.
76 Do not send any email. Overdue notices that would have been sent to
77 the patrons or to the admin are printed to standard out. CSV data (if
78 the -csv flag is set) is written to standard out or to any csv
83 Items older than max days are assumed to be handled somewhere else,
84 probably the F<longoverdues.pl> script. They are therefore ignored by
85 this program. No notices are sent for them, and they are not added to
86 any CSV files. Defaults to 90 to match F<longoverdues.pl>.
90 select overdues for one specific library. Use the value in the
91 branches.branchcode table.
95 Produces CSV data. if -n (no mail) flag is set, then this CSV data is
96 sent to standard out or to a filename if provided. Otherwise, only
97 overdues that could not be emailed are sent in CSV format to the admin.
99 =item B<-itemscontent>
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 issuedate,title,barcode,author
105 Other possible values come from fields in the biblios, items, and
112 This script is designed to alert patrons and administrators of overdue
117 This script pays attention to the overdue notice configuration
118 performed in the "Overdue notice/status triggers" section of the
119 "Tools" area of the staff interface to Koha. There, you can choose
120 which letter templates are sent out after a configurable number of
121 days to patrons of each library. More information about the use of this
122 section of Koha is available in the Koha manual.
124 The templates used to craft the emails are defined in the "Tools:
125 Notices" section of the staff interface to Koha.
127 =head2 Outgoing emails
129 Typically, messages are prepared for each patron with overdue
130 items. Messages for whom there is no email address on file are
131 collected and sent as attachments in a single email to each library
132 administrator, or if that is not set, then to the email address in the
133 C<KohaAdminEmailAddress> system preference.
135 These emails are staged in the outgoing message queue, as are messages
136 produced by other features of Koha. This message queue must be
137 processed regularly by the
138 F<misc/cronjobs/process_message_queue.pl> program.
140 In the event that the C<-n> flag is passed to this program, no emails
141 are sent. Instead, messages are sent on standard output from this
142 program. They may be redirected to a file if desired.
146 Templates can contain variables enclosed in double angle brackets like
147 E<lt>E<lt>thisE<gt>E<gt>. Those variables will be replaced with values
148 specific to the overdue items or relevant patron. Available variables
153 =item E<lt>E<lt>bibE<gt>E<gt>
155 the name of the library
157 =item E<lt>E<lt>items.contentE<gt>E<gt>
159 one line for each item, each line containing a tab separated list of
160 title, author, barcode, issuedate
162 =item E<lt>E<lt>borrowers.*E<gt>E<gt>
164 any field from the borrowers table
166 =item E<lt>E<lt>branches.*E<gt>E<gt>
168 any field from the branches table
174 The C<-csv> command line option lets you specify a file to which
175 overdues data should be output in CSV format.
177 With the C<-n> flag set, data about all overdues is written to the
178 file. Without that flag, only information about overdues that were
179 unable to be sent directly to the patrons will be written. In other
180 words, this CSV file replaces the data that is typically sent to the
181 administrator email address.
183 =head1 USAGE EXAMPLES
185 C<overdue_notices.pl> - In this most basic usage, with no command line
186 arguments, all libraries are procesed individually, and notices are
187 prepared for all patrons with overdue items for whom we have email
188 addresses. Messages for those patrons for whom we have no email
189 address are sent in a single attachment to the library administrator's
190 email address, or to the address in the KohaAdminEmailAddress system
193 C<overdue_notices.pl -n -csv /tmp/overdues.csv> - sends no email and
194 populates F</tmp/overdues.csv> with information about all overdue
197 C<overdue_notices.pl -library MAIN max 14> - prepare notices of
198 overdues in the last 2 weeks for the MAIN library.
202 The F<misc/cronjobs/advance_notices.pl> program allows you to send
203 messages to patrons in advance of thier items becoming due, or to
204 alert them of items that have just become due.
