Bug ID: 41706
Summary: "Use of uninitialized value..." warning in
C4/Record.pm
Initiative type: ---
Sponsorship ---
status:
Product: Koha
Version: Main
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P5 - low
Component: OPAC
Assignee: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
The warning:
[WARN] Use of uninitialized value $2 in split
at /kohadevbox/koha/C4/Record.pm line 924.
appears in the plack-opac-error.log file.
To reproduce in KTD:
1. Observe plack-opac-error.log
2. In OPAC go to record with one word author like Aristophanes,
Aristotle or Xenophon (biblionumbers: 64, 176, 254)
3. Show it in any of "detail" view (Normal, MARC, ISBD)
4. Warning appears in plack-opac-error.log
It happens during the preparation of data for the "Cite" feature
in OPAC. The warning appears because of the overlap of two regular
expression matches - the variable captured from the first regular
expression match is changed (by the second regular expression match)
before it is used.
