    $leave = $this->one_model->get('table', $id);

    $staff = $this->one_model->get('staff', $leave->created_by);

    $approver = $this->one_model->get('staff', $staff->leave_approver_id);

    $organization = $this->one_model->get('organizations', $leave->org_id);

    $apply_date = date_create($leave->created_at);

    $apply_date = date_format($apply_date, DATE_FORMAT);

    $date_start = date_create($leave->date_start);

    $date_start = date_format($date_start, DATE_FORMAT);

    $date_end = date_create($leave->date_end);

    $date_end = date_format($date_end, DATE_FORMAT);

    // construct msg - with invoice link inside

    $message = '

Tarikh Permohonan: '.$apply_date.'

Tarikh Mula: '.$date_start.'

    $this->load->library('mailgun');

    $this->mailgun->from("$organization->name<postmaster@mg.smap.my>");

    $this->mailgun->reply_to($organization->email);

    $this->mailgun->to($approver->email);

    $this->mailgun->bcc('hello@smap.my');

    $this->mailgun->subject("Permohonan Cuti ($staff->name)");

    $this->mailgun->message($message);

    $this->mailgun->send();

  }

Controller process
