Codeigniter:如何从数据库获取今天和过去15天之间的数据

Question

我的数据库表如下所示

| id | user_name | address | contact | date | |----|-----------|---------|---------|----------| | 1 | john | NY | 12345 |2015-4-20 | | 2 | Mart | NY | 54345 |2015-4-05 | | 3 | Drew | US | 67340 |2015-3-14 |

我的controller功能是

function orders()
{

  $data['orders'] = $this->common_model->get_data_between_15days('tbl_orders',array('status'=>'1'));
  $data['title']='Orders';
  $data['main_content']='users/orders_view.php';
  $this->load->view('admin/includes/template',$data);

}

我的model功能是

   public function get_data_between_15days($table, $condition)
   { 

    $result = $this->db->get_where($table, $condition);
    if($result)
      {
        return $result->result_array();
      }
   }

现在我想从数据库获取今天和过去15天之间的记录.我试过这样的

 $result = $this->db->query('SELECT * FROM '.$table.' WHERE date BETWEEN DATE_SUB(NOW(), INTERVAL 15 DAY) AND NOW(); AND '.$condition);

但它不起作用.我想获得过去15到30天之间的所有记录.我很感谢你的帮助.谢谢.

使用CodeIgniter标准查询

$this->db->select('*');
$this->db->where('date BETWEEN DATE_SUB(NOW(), INTERVAL 15 DAY) AND NOW()');
$this->db->where($conditions);
$result = $this->db->get($table);
