CODEIGNITER，来自 2 个表的参考数据显示在视图文件中

Question

正在尝试交叉引用来自 2 table 秒的数据并且仅显示来自 table 秒中的 1 秒的数据...

如果 table 001 中的“地区”与 table 002 中的“地区”匹配，那么我想从 table 002

TABLE001

|  month_of_report  |  district  |    org     |  
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
|      January      |   004     |    Dallas  |
|      February     |   029     |    Dallas  |
|      March        |   047     |    Dallas  |

TABLE002

|  coordinator  |  district  |
- - - - - - - - - - - - - - - 
|      Jamie    |   004      |
|      Susie    |   047      |
|      Jimmy    |   029      |

型号

    public function reg_co()
    {
        $this->db->where('report_month', $report_month);
        $query = $this->db->get('non_clinical_total_tests');

        $this->db->select('*');
        $this->db->from('coordinator');
        $this->db->join('non_clinical_total_tests', 'non_clinical_total_tests.district = coordinator.district');

        if($query->num_rows() > 0)
        {
            return $query->row();
        }

    }

控制器

          $data['reg_co'] = $this->Page_model->reg_co();

查看文件

            <?php if($reg_co) : ?>
                  <strong>DISTRICT: </strong><?php echo $reg_co->district; ?><br>

期望的结果

如果来自 2 table 的学区匹配，那么我应该能够回复该学区的协调员。
