https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=37865 --- Comment #1 from Peter Vashchuk <stalkernoid@gmail.com> --- Created attachment 171182 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=171182&action=edit Bug 37865: Fix uninitialized value warn Use of uninitialized value $op in string eq at /home/vagrant/kohaclone/circ/circulation.pl line 145.: /home/vagrant/kohaclone/circ/circulation.pl This happened because in cases when $op was undef and circulation.pl tried to directly compare it to string. To reproduce: 1. Go to "Check Out" page of a patron, or refresh already opened one. 2. Check your logs for "Use of uninitialized value $op" warn. 3. Apply patch. 4. Repeat step 1 and check that there's no new "Use of uninitialized value $op" error -- You are receiving this mail because: You are watching all bug changes. You are the assignee for the bug.
