Bug ID: 7722
Assignee: [email protected]
Summary: Insidious problem with searching
QA Contact: [email protected]
Severity: enhancement
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: All
Status: NEW
Version: rel_3_8
Component: Searching
Product: Koha
I cannot find the root cause of this issue, but multiple libraries that I am
aware of have problems searching on particular search terms ( and never the
same terms at the same library ). The error they get when they trigger this
problem is:
Tag "" is not a valid tag. at /home/koha/kohaclone/C4/Biblio.pm line 1849
Something somewhere is adding empty keys to C4::Context->marcfromkohafield, I
think it may have something to do with the analytics feature that was added.
In the while loop for TransformKohaToMarc, there is a line
next unless my $dtm = $db_to_marc->{''}->{$name};
I don't think it's working.
If I dump $dtm, for each search, I see the dump twice.
It looks like this:
$VAR1 = [
'952',
'w'
];
$VAR1 = [];
I think the second time, when it is empty is what's breaking this.
The next never fails because even though it is empty, it is still a valid
arrayref.
The solution I have some up with is to skip over the elements where the
arrayref is empty.
