The array elements are hash refs whose keys are name, value and encvalue, and whose values are the name of a search parameter, the value of that search parameter and the URL encoded value of that parameter. The search parameter names are lccn, isbn, issn, title, author, dewey and subject. The search parameter values are obtained from the bibliographic record whose data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData(). If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g. a general purpose search argument. In this case, the returned array contains only entry: the key is 'title' and the value and encvalue are derived from $matchpoints. If a search parameter value is undefined or empty, it is not included in the returned array. The returned array reference may be passed directly to the template parameters. =over 2 =item C * $array containing hash refs as described above =item C =back $data = Biblio::GetBiblioData($bibno); $template->param ( MYLOOP => C4::Search::z3950_search_args($data) ) *OR* $template->param ( MYLOOP => C4::Search::z3950_search_args($searchscalar) ) =cut sub z3950_search_args { my $bibrec = shift; my $isbn = Business::ISBN->new($bibrec); if (defined $isbn && $isbn->is_valid) { $bibrec = { isbn => $bibrec } if !ref $bibrec; } else { $bibrec = { title => $bibrec } if !ref $bibrec; } my $array = []; for my $field (qw/ lccn isbn issn title author dewey subject /) { my $encvalue = URI::Escape::uri_escape_utf8($bibrec->{$field}); push @$array, { name=>$field, value=>$bibrec->{$field}, encvalue=>$encvalue } if defined $bibrec->{$field}; } return $array; } =head2 GetDistinctValues($field); C<$field> is a reference to the fields array =cut sub GetDistinctValues { my ($fieldname,$string)=@_; # returns a reference to a hash of references to branches... if ($fieldname=~/\./){ my ($table,$column)=split /\./, $fieldname; my $dbh = C4::Context->dbh; warn "select DISTINCT($column) as value, count(*) as cnt from $table group by lib order by $column " if $DEBUG; my $sth = $dbh->prepare("select DISTINCT($column) as value, count(*) as cnt from $table ".($string?" where $column like \"$string%\"":"")."group by value order by $column "); $sth->execute; my $elements=$sth->fetchall_arrayref({}); return $elements; } else { $string||= qq(""); my @servers=qw; my (@zconns,@results); for ( my $i = 0 ; $i < @servers ; $i++ ) { $zconns[$i] = C4::Context->Zconn( $servers[$i], 1 ); $results[$i] = $zconns[$i]->scan( ZOOM::Query::CCL2RPN->new( qq"$fieldname $string", $zconns[$i]) ); } # The big moment: asynchronously retrieve results from all servers my @elements; while ( ( my $i = ZOOM::event( \@zconns ) ) != 0 ) { my $ev = $zconns[ $i - 1 ]->last_event(); if ( $ev == ZOOM::Event::ZEND ) { next unless $results[ $i - 1 ]; my $size = $results[ $i - 1 ]->size(); if ( $size > 0 ) { for (my $j=0;$j<$size;$j++){ my %hashscan; @hashscan{qw(value cnt)}=$results[ $i - 1 ]->display_term($j); push @elements, \%hashscan; } } } } return \@elements; } } END { } # module clean-up code here (global destructor) 1; __END__ =head1 AUTHOR Koha Development Team =cut
