74 Prints the manual page and exits.
78 Verbose. Without this flag set, only fatal errors are reported.
82 Do not send any email. Overdue notices that would have been sent to
83 the patrons or to the admin are printed to standard out. CSV data (if
84 the -csv flag is set) is written to standard out or to any csv
89 Items older than max days are assumed to be handled somewhere else,
90 probably the F<longoverdues.pl> script. They are therefore ignored by
91 this program. No notices are sent for them, and they are not added to
92 any CSV files. Defaults to 90 to match F<longoverdues.pl>.
96 select overdues for one specific library. Use the value in the
97 branches.branchcode table. This option can be repeated in order
98 to select overdues for a group of libraries.
102 Produces CSV data. if -n (no mail) flag is set, then this CSV data is
103 sent to standard out or to a filename if provided. Otherwise, only
104 overdues that could not be emailed are sent in CSV format to the admin.
108 Produces html data. if patron does not have a mail address or
109 -n (no mail) flag is set, an html file is generated in the specified
110 directory. This can be downloaded or futher processed by library staff.
112 =item B<-itemscontent>
114 comma separated list of fields that get substituted into templates in
115 places of the E<lt>E<lt>items.contentE<gt>E<gt> placeholder. This
116 defaults to due date,title,barcode,author
118 Other possible values come from fields in the biblios, items and
123 Repetable field, that permit to select only few of patrons categories.
127 Repetable field, permis to exclude some patrons categories.
129 =item B<-t> | B<--triggered>
131 This option causes a notice to be generated if and only if
132 an item is overdue by the number of days defined in a notice trigger.
134 By default, a notice is sent each time the script runs, which is suitable for
135 less frequent run cron script, but requires syncing notice triggers with
136 the cron schedule to ensure proper behavior.
137 Add the --triggered option for daily cron, at the risk of no notice
138 being generated if the cron fails to run on time.
142 Default items.content lists only those items that fall in the
143 range of the currently processing notice.
144 Choose list-all to include all overdue items in the list (limited by B<-max> setting).
150 This script is designed to alert patrons and administrators of overdue
155 This script pays attention to the overdue notice configuration
156 performed in the "Overdue notice/status triggers" section of the
157 "Tools" area of the staff interface to Koha. There, you can choose
158 which letter templates are sent out after a configurable number of
159 days to patrons of each library. More information about the use of this
160 section of Koha is available in the Koha manual.
162 The templates used to craft the emails are defined in the "Tools:
163 Notices" section of the staff interface to Koha.
165 =head2 Outgoing emails
167 Typically, messages are prepared for each patron with overdue
168 items. Messages for whom there is no email address on file are
169 collected and sent as attachments in a single email to each library
170 administrator, or if that is not set, then to the email address in the
171 C<KohaAdminEmailAddress> system preference.
173 These emails are staged in the outgoing message queue, as are messages
174 produced by other features of Koha. This message queue must be
175 processed regularly by the
176 F<misc/cronjobs/process_message_queue.pl> program.
178 In the event that the C<-n> flag is passed to this program, no emails
179 are sent. Instead, messages are sent on standard output from this
180 program. They may be redirected to a file if desired.
184 Templates can contain variables enclosed in double angle brackets like
185 E<lt>E<lt>thisE<gt>E<gt>. Those variables will be replaced with values
186 specific to the overdue items or relevant patron. Available variables
191 =item E<lt>E<lt>bibE<gt>E<gt>
193 the name of the library
195 =item E<lt>E<lt>items.contentE<gt>E<gt>
197 one line for each item, each line containing a tab separated list of
198 title, author, barcode, issuedate
200 =item E<lt>E<lt>borrowers.*E<gt>E<gt>
202 any field from the borrowers table
204 =item E<lt>E<lt>branches.*E<gt>E<gt>
206 any field from the branches table
212 The C<-csv> command line option lets you specify a file to which
213 overdues data should be output in CSV format.
215 With the C<-n> flag set, data about all overdues is written to the
216 file. Without that flag, only information about overdues that were
217 unable to be sent directly to the patrons will be written. In other
218 words, this CSV file replaces the data that is typically sent to the
219 administrator email address.
221 =head1 USAGE EXAMPLES
223 C<overdue_notices.pl> - In this most basic usage, with no command line
224 arguments, all libraries are procesed individually, and notices are
225 prepared for all patrons with overdue items for whom we have email
226 addresses. Messages for those patrons for whom we have no email
227 address are sent in a single attachment to the library administrator's
228 email address, or to the address in the KohaAdminEmailAddress system
231 C<overdue_notices.pl -n -csv /tmp/overdues.csv> - sends no email and
232 populates F</tmp/overdues.csv> with information about all overdue
235 C<overdue_notices.pl -library MAIN max 14> - prepare notices of
236 overdues in the last 2 weeks for the MAIN library.
240 The F<misc/cronjobs/advance_notices.pl> program allows you to send
241 messages to patrons in advance of thier items becoming due, or to
242 alert them of items that have just become due.
