https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23925 Bug ID: 23925 Summary: Value builder plugin to check ISBN validity Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: enhancement Priority: P5 - low Component: Cataloging Assignee: koha-bugs@lists.koha-community.org Reporter: pasi.kallinen@koha-suomi.fi QA Contact: testopia@bugs.koha-community.org CC: m.de.rooy@rijksmuseum.nl This patch adds a new value builder plugin ISBN.pl, which should be attached to field 020a. The plugin will perform a simple checksum checking when trying to save the record, and inform the user that the ISBN is illegal if the checksum doesn't match. The ISBN plugin is a test case for additional value builder plugin functionality that lets the plugins check field values and prevent saving if so desired. The example plugin has been updated with information on how to write a pre-save check function. To test: 1) Add the ISBN.pl plugin to the field 020a in MARC subfield structure admin. 2) Go to cataloguing and try to save the record, no complaints about the ISBN (Because the plugin will not complain about empty field) 3) Enter something in the 020a field and try to save, you should receive a complaint about illegal ISBN. 4) Enter a valid ISBN (eg. 978-951-1-27641-8) and try to save, there should be no complaints about the ISBN. -- You are receiving this mail because: You are the assignee for the bug.
