79 Print a brief help message and exits.
83 Prints the manual page and exits.
87 Verbose. Without this flag set, only fatal errors are reported.
91 Do not send any email. Overdue notices that would have been sent to
92 the patrons or to the admin are printed to standard out. CSV data (if
93 the -csv flag is set) is written to standard out or to any csv
98 Items older than max days are assumed to be handled somewhere else,
99 probably the F<longoverdues.pl> script. They are therefore ignored by
100 this program. No notices are sent for them, and they are not added to
101 any CSV files. Defaults to 90 to match F<longoverdues.pl>.
105 select overdues for one specific library. Use the value in the
106 branches.branchcode table. This option can be repeated in order
107 to select overdues for a group of libraries.
111 Produces CSV data. if -n (no mail) flag is set, then this CSV data is
112 sent to standard out or to a filename if provided. Otherwise, only
113 overdues that could not be emailed are sent in CSV format to the admin.
117 Produces html data. If patron does not have an email address or
118 -n (no mail) flag is set, an HTML file is generated in the specified
119 directory. This can be downloaded or futher processed by library staff.
120 The file will be called notices-YYYY-MM-DD.html and placed in the directory
125 Produces plain text data. If patron does not have an email address or
126 -n (no mail) flag is set, a text file is generated in the specified
127 directory. This can be downloaded or futher processed by library staff.
128 The file will be called notices-YYYY-MM-DD.txt and placed in the directory
131 =item B<-itemscontent>
133 comma separated list of fields that get substituted into templates in
134 places of the E<lt>E<lt>items.contentE<gt>E<gt> placeholder. This
135 defaults to due date,title,barcode,author
137 Other possible values come from fields in the biblios, items and
142 Repetable field, that permit to select only few of patrons categories.
146 Repetable field, permis to exclude some patrons categories.
148 =item B<-t> | B<--triggered>
150 This option causes a notice to be generated if and only if
151 an item is overdue by the number of days defined in a notice trigger.
153 By default, a notice is sent each time the script runs, which is suitable for
154 less frequent run cron script, but requires syncing notice triggers with
155 the cron schedule to ensure proper behavior.
156 Add the --triggered option for daily cron, at the risk of no notice
157 being generated if the cron fails to run on time.
161 Default items.content lists only those items that fall in the
162 range of the currently processing notice.
163 Choose list-all to include all overdue items in the list (limited by B<-max> setting).
167 use it in order to send overdues on a specific date and not Now.
171 Allows to specify which type of email will be used. Can be email, emailpro or B_email. Repeatable.
177 This script is designed to alert patrons and administrators of overdue
182 This script pays attention to the overdue notice configuration
183 performed in the "Overdue notice/status triggers" section of the
184 "Tools" area of the staff interface to Koha. There, you can choose
185 which letter templates are sent out after a configurable number of
186 days to patrons of each library. More information about the use of this
187 section of Koha is available in the Koha manual.
189 The templates used to craft the emails are defined in the "Tools:
190 Notices" section of the staff interface to Koha.
192 =head2 Outgoing emails
194 Typically, messages are prepared for each patron with overdue
195 items. Messages for whom there is no email address on file are
196 collected and sent as attachments in a single email to each library
197 administrator, or if that is not set, then to the email address in the
198 C<KohaAdminEmailAddress> system preference.
200 These emails are staged in the outgoing message queue, as are messages
201 produced by other features of Koha. This message queue must be
202 processed regularly by the
203 F<misc/cronjobs/process_message_queue.pl> program.
205 In the event that the C<-n> flag is passed to this program, no emails
206 are sent. Instead, messages are sent on standard output from this
207 program. They may be redirected to a file if desired.
211 Templates can contain variables enclosed in double angle brackets like
212 E<lt>E<lt>thisE<gt>E<gt>. Those variables will be replaced with values
213 specific to the overdue items or relevant patron. Available variables
218 =item E<lt>E<lt>bibE<gt>E<gt>
220 the name of the library
222 =item E<lt>E<lt>items.contentE<gt>E<gt>
224 one line for each item, each line containing a tab separated list of
225 title, author, barcode, issuedate
227 =item E<lt>E<lt>borrowers.*E<gt>E<gt>
229 any field from the borrowers table
231 =item E<lt>E<lt>branches.*E<gt>E<gt>
233 any field from the branches table
239 The C<-csv> command line option lets you specify a file to which
240 overdues data should be output in CSV format.
242 With the C<-n> flag set, data about all overdues is written to the
243 file. Without that flag, only information about overdues that were
244 unable to be sent directly to the patrons will be written. In other
245 words, this CSV file replaces the data that is typically sent to the
246 administrator email address.
248 =head1 USAGE EXAMPLES
250 C<overdue_notices.pl> - In this most basic usage, with no command line
251 arguments, all libraries are procesed individually, and notices are
252 prepared for all patrons with overdue items for whom we have email
253 addresses. Messages for those patrons for whom we have no email
254 address are sent in a single attachment to the library administrator's
255 email address, or to the address in the KohaAdminEmailAddress system
258 C<overdue_notices.pl -n -csv /tmp/overdues.csv> - sends no email and
259 populates F</tmp/overdues.csv> with information about all overdue
262 C<overdue_notices.pl -library MAIN max 14> - prepare notices of
263 overdues in the last 2 weeks for the MAIN library.
267 The F<misc/cronjobs/advance_notices.pl> program allows you to send
268 messages to patrons in advance of thier items becoming due, or to
269 alert them of items that have just become due.
