php - 我必须显示一个新字段计数。这是 jil_mrorfq 表中每个需求 id 的计数

Question

我有一个分页管理页面，其中包含需求服务、发布者、管理者、数量、发布于、表需求中的状态等字段。我必须显示一个新的归档计数。即 jil_mrorfq 表中每个需求 id 的计数。 我完成了管理部分。但我不知道如何显示计数，如何与此代码一起获取。任何人都知道查询，请帮助我完成此任务。 我正确地完成了分页管理页面。但是每个需求 ID 的计数必须显示为表中的下一个字段。我完全困惑它如何获取。查询将如何编写。有人知道答案，那么请帮助我完成这个任务。

使用下面的代码

  public function fetch_data($limit, $start) {
      $this->db->limit($limit, $start);
      $this->db->from('jil_requirements');
      $this->db->join('jil_users', 'jil_requirements.rqm_userid=jil_users.usr_id', 'left');
      $this->db->join('jil_merchants', 'jil_requirements.rqm_createdempid=jil_merchants.mer_id', 'left');
      $this->db->where('jil_requirements.rqm_permission!=', '4');
      $query =  $this->db->get();  
      if ($query->num_rows() > 0) {
      foreach ($query->result() as $row) {
          $this->db->select('count(jil_mrorfq.rfq_requirementid) as total'); 
          $this->db->from('jil_mrorfq'); 
          $this->db->where('jil_mrorfq.rfq_requirementid',$row->rqm_id);
          $this->db->group_by('jil_mrorfq.rfq_requirementid'); 
          $query2= $this->db->get()->row_object();

         $row->total_count = $query2->total;
         $data[] = $row;
                }
               return $data;
            }
            return false;
       }
