Perhaps there is a confusion. Your subroutine
db_retrieve_records returns a reference
to the @loop array, not the @loop array itself. If that
is the return value you want for db_retrieve_records, then
the mail routine needs correcting.
First, save the reference to @loop:
my $loop = db_retrieve_records();
Then access loop information with the -> dereferencing op:
for my $i (0..@$loop-1) {
foreach (qw( action type domain priority target )) {
$body .= $loop->[$i]{$_};
}
$body .= "\n";
}
Note also that I used @$loop-1 for the last element of
the outer loop.
UPDATE: Mr. Freidman's is a much simpler fix.
Consider mine as an alternative way to do it :)
