The following is intended to sort an array of hash refs based on
id_type. It is not working however. Does anyone know why?
use Data::Dumper;
our %datatype_sort = (
bill => 0,
reg => 10,
);
my @ary = (
{id_type => 'reg', id => 'KY200616813'},
{id_type => 'bill', id => 'CA2005000A5'},
{id_type => 'bill', id => 'CA2005000A250'},
);
my @x = sort _sortval_datatype @ary;
print Dumper(\@x);
sub _sortval_datatype {
my($av, $bv) = @_;
return $datatype_sort{$av->{id_type}} <=>
$datatype_sort{$bv->{id_type}};
}
sub _sortval_datatype {
return $datatype_sort{$a->{id_type}} <=> $datatype_sort{$b->{id_type}};
}
