I think you want to have a batch query that will add data on 2 tables otherwise none of them will have the data. If that so, Try to use

$this->db->trans_begin();

$this->db->query('AN SQL QUERY...');
$this->db->query('ANOTHER QUERY...');
$this->db->query('AND YET ANOTHER QUERY...');

if ($this->db->trans_status() === FALSE)
{
        $this->db->trans_rollback();
}
else
{
        $this->db->trans_commit();
}

please read: https://www.codeigniter.com/user_guide/database/transactions.html

that will allow you to commit or rollback queries .
