I have a simple question that needs to get an element when selecting that reference ID by an input form. I used the following code to do that.

$id2=$locationProducts[0]->inventory_update_stock_details_id;

But this code outs only the first element always. AS an exmple inventory_update_stock_details_id=36, inventory_update_stock_details_id=36, inventory_update_stock_details_id=36 and so on.

But I needs to select as inventory_update_stock_details_id=35, inventory_update_stock_details_id=345, inventory_update_stock_details_id=2 like that.

inventory_update_stock_details_id included ids as 1,2,3,4,5,……1000

The model as follows :

function getInventoryLocationProducts()
    {
        $this->db->select("*");
        $this->db->from('store_inventory_update_stock_details');
        $this->db->join('store_inventory_item', 'store_inventory_item.inventory_item_id=store_inventory_update_stock_details.inventory','left');
        $this->db->join('store_inventory_location_update', 'store_inventory_location_update.inventory_update_stock_id=store_inventory_update_stock_details.inventory_update_stock_id','left');
        $this->db->join('store_inventory_update_stock', 'store_inventory_update_stock.inventory_update_stock_id=store_inventory_location_update.inventory_update_stock_id','left');
        $this->db->where('store_inventory_item.status=1');
        $this->db->where('store_inventory_update_stock_details.serial_no NOT IN (select serial_no from store_inventory_location_update)');
        
        $q = $this->db->get_where();
        
        if ($q->num_rows() > 0) {
            return $q->result();
        }

        return FALSE;
    }

    $this->checkPermissions('add', 'inventoryLocation');

                            </td>

What can modify my code line to do that. Can anyone help me ?
