https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=20592 --- Comment #5 from M. Tompsett <mtompset@hotmail.com> --- Test plan is the same as comment #1. Testing on a kohadevbox after a reset all. blanking the log before clicking update: echo | sudo tee /var/log/koha/kohadev/plack-error.log Used the same url given: http://localhost:8081/cgi-bin/koha/catalogue/moredetail.pl?biblionumber=1&itemnumber=1 Before my two patches, noise and update triggers more. After my two patches, no noise. David's patch works, but if there are other places which need the same check they would have to be modified too. The ModItem function should be validating its parameters. Also, I don't believe you need to check for biblionumber in your condition, David. My first patch adds that validation, so other functions receive the same fix. My second just cleans up some noise, since the first warning wasn't the only noise triggered. -- You are receiving this mail because: You are watching all bug changes.
