foreach codeigniter内のアクセスクエリ

Question

誰でも私を助けることができます、私はcodeigniterフレームワークの新機能です。私は、test_kindテーブルに接続されている会計テーブルの下に価格フィールドを取得しようとしていますか？

ありがとう..

モデル

public function get_pending_test($row_id){ 

    $where = "statust='0' and tyre_no=$row_id"; 
    $this->db->select('lab_id, tyre_no, test') 
      ->from('test_kind') 
      ->where($where); 
    $query = $this->db->get(); 

    //return $query->result_array(); If i put this code it will return the lab_id, tyre_no, test, but I need to get the price field on the accounting table. 

    foreach($query->result_array() as $row){ 

     $this->db->select('price') 
       ->from('accounting') 
       ->where('test', $row['test']) 
       ->where('sample_idacc', $row['tyre_no']); 
     $query = $this->db->get()->row(); 
    } 
}

$query = $this->db->query(

          test_kind.lab_id, 
          test_kind.tyre_no,

          accounting 
         ON 
          test_kind.tyre_no = accounting.sample_idacc 
         WHERE 
          statust='0' and 
          tyre_no= $row_id;" 
        ); 
$result = $query->result_array(); 
return $result;

このようなレコードを取得するには、Joinを使用します。

$this->db->select('tk.lab_id, tk.tyre_no, tk.test,a.price') 
$this->db->from('test_kind' as tk) 
$this->db->join("accounting as a","a.sample_idacc = tk.tyre_no","LEFT"); 
$this->db->where('tk.status',0); 
$this->db->where('tk.tyre_no',$row_id); 
$query = $this->db->get(); 

return $query->result_array();
