Набор данных MySQL Codeigniter не отфильтрован

У меня есть простая программа магазинов, разработанная с использованием Codeigniter. Ниже приведены основные таблицы.

store_item 

+---------+----------------+---------------+--------+
| item_id |   item_name    | item_sub_type | status |
+---------+----------------+---------------+--------+
|       1 | A4             |           100 |      1 |
|       2 | A5             |           100 |      1 |
|       3 | CFL Bulb 15W   |           102 |      1 |
|       4 | Toilet Cleaner |           102 |      1 |
+---------+----------------+---------------+--------+

item_sub_type

| sub_type_id | sub_type_name | cat | status |

|         101 | Electric Item | S   |      1 |
|         102 | Consumable    | S   |      1 |
|         103 | Vehicle Spare | V   |      1 |
+-------------+---------------+-----+--------+

store_update_stock 

+-----------------+----------------+--------------+-----------------+--------+

Выданные количества в таблице store_update_stock_details помечены знаком минус (-).

Я пытался получить отфильтрованную сводку по элементу & item_sub_type

Контроллер отчетов 

public function stockReport()
    {
        $bc = array(array('link' => '#', 'page' => 'Stationary Stock Report'));
        $meta = array('page_title' => 'Stationary Stock Report', 'bc' => $bc);
        $where = NULL;
        if ($this->input->post('item')) {
            $item = $this->input->post('item');

            $where .= " AND store_item.item_id = '$item' ";

        } else {
            $item = NULL;
        }

        $where = NULL;
        if ($this->input->post('subType')) {
            $subType = $this->input->post('subType');
            $where .= " AND store_sub_type.sub_type_id = '$subType' ";
        } else {
            $subType = NULL;
        }

        $this->data['item'] = $this->Item_Model->getItem();        
        $this->data['subType'] = $this->Item_Model->getSubType();
        $this->data['summary'] = $this->Report_model->stockSummary($where);    
        $this->render('reports/stockReport', $meta, $this->data);
    }

Item_model 

function getItem()
    {
        $q = $this->db->get_where('store_item', array('status' => '1'));
        if ($q->num_rows() > 0) {
            return $q->result();
        }
        return FALSE;
    }

    function getSubType()
    {
        $this->db->select("*");
        $this->db->from('store_sub_type');        
        $this->db->where("status=1 and cat='S'  ");       
        $this->db->order_by('sub_type_id');
        $q1 = $this->db->get();
        if ($q1->num_rows() > 0) {
            return $q1->result();
        }
        return FALSE;
    }

Приведенные выше таблицы и коды правильно генерируют следующий вывод 

+---------+----------------+---------------+-------+--------+---------+
| item_id |   item_name    | item_sub_type | p_qty | is_qty | balance |
+---------+----------------+---------------+-------+--------+---------+
|       1 | A4             | Stationary    |    30 |     15 |      15 |
|       2 | A5             | Stationary    |     5 |      0 |       5 |
|       3 | CFL Bulb 15W   | Consumable    |   100 |     10 |      90 |
|       4 | Toilet Cleaner | Consumable    |    15 |      2 |      13 |
+---------+----------------+---------------+-------+--------+---------+

Затем мне нужно отфильтровать этот отчет по item_name & item_sub_type следующим образом 

+---------+-----------+---------------+-------+--------+---------+
| item_id | item_name | item_sub_type | p_qty | is_qty | balance |
+---------+-----------+---------------+-------+--------+---------+
|       1 | A4        | Stationary    |    30 |     15 |      15 |
|       2 | A5        | Stationary    |     5 |      0 |       5 |
+---------+-----------+---------------+-------+--------+---------+

+---------+----------------+---------------+-------+--------+---------+
| item_id |   item_name    | item_sub_type | p_qty | is_qty | balance |
+---------+----------------+---------------+-------+--------+---------+
|       3 | CFL Bulb 15W   | Consumable    |   100 |     10 |      90 |
|       4 | Toilet Cleaner | Consumable    |    15 |      2 |      13 |
+---------+----------------+---------------+-------+--------+---------+

Но фильтры (item_name & item_sub_type) не фильтровали записи правильно. Я думаю, что я сделал коды для фильтров хорошо. Что может быть не так?

Кто-нибудь может мне помочь?

Вы установили $ where = NULL 2 раза, поэтому для его удаления 1-го условия из предложения where,

просто удалите 2-е $ где = NULL, все будет хорошо. 

public function stockReport()
{
