From 37902b25a7aa5c9e1b3f90e8cbb50741b27dae1d Mon Sep 17 00:00:00 2001 From: Paul Poulain Date: Fri, 2 Sep 2011 18:39:53 +0200 Subject: [PATCH] Bug 6840 warning in logs In staff interface, in search (catalogue/search.pl), there is a warning saying: [Fri Sep 2 18:20:24 2011] search.pl: Use of uninitialized value $key in hash element at /home/paul/koha.dev/koha-community/C4/Templates.pm line 227. The problem happens when searching from the quick search toolbar, not when you search from advanced search. Investigating, it seems it's because the sort_by is not defined in this case. This patch * fixes the problem in Search.pl by setting the parameter only if there is a sort_by field * modify te Template->param sub to get a better error message. Instead of having just "use of uninitia..." get the value you try to set to an empty key.
