DBI is interpreting the ? as a placeholder, and inserting a NULL in its place.

Code like this is cleaner, and will solve your problem:

my $query = q(  INSERT into messages VALUES(?, ?, ?, ?, ?, ?)  );
my $sth = $dbh->($query);
$sth->execute($name, $email, $date, $subject, $message, $id);

DBI takes care of all the quoting for you.
