我想在codeigniter中将此查询转换为Ignited datatable查询

我不知道如何将这个长模型函数转换为ignited datatable查询。我用点燃的数据表完成了一些小的选择功能。有人知道吗？
我不知道如何隐藏它。有什么功能可以做吗

   public function fetch_data() {

              $this->db->from('jil_requirements');
              $this->db->join('jil_users', 'jil_requirements.rqm_userid=jil_users.usr_id', 'left');

              $this->db->where('jil_requirements.rqm_permission!=', '4');
              $this->db->order_by("jil_requirements.rqm_id", "desc");
              $query =  $this->db->get();  
              if ($query->num_rows() > 0) {
              foreach ($query->result() as $row) {
                 $this->db->select('count(jil_mrorfq.rfq_requirementid) as total');

首先，您必须加载ignited dataTables库

    $this->load->library('datatables');

或

将其添加到Autoloader，以便在Codeigniter应用程序启动时自动加载

在那之后，改变一切

      $this->db->

在您的查询中

     $this->datatables

最后，您必须使用它对json数组中的数据进行编码

      $this->datatables->generate();

让我知道我是否还能帮上忙

更新

public function fetch_data() {

          $this->datatables->from('jil_requirements');
          $this->datatables->join('jil_users',         'jil_requirements.rqm_userid=jil_users.usr_id', 'left');
          $this->datatables->join('jil_merchants', 'jil_requirements.rqm_createdempid=jil_merchants.mer_id', 'left');
          $this->datatables->where('jil_requirements.rqm_permission!=', '4');
          $this->datatables->order_by("jil_requirements.rqm_id", "desc");
          $query =  $this->datatables->get();  

         if ($query->num_rows() > 0) {

          foreach ($query->result() as $row) {
             $this->datatables->select('count(jil_mrorfq.rfq_requirementid) as total'); 
            $this->datatables->from('jil_mrorfq'); 
           $this->datatables->join('jil_requirements', 'jil_requirements.rqm_id=jil_mrorfq.rfq_requirementid', 'left'); 
           $this->datatables->where('jil_requirements.rqm_id',$row->rqm_id);
              $query2= $this->datatables->get()->row_object();
             $row->total_count = $query2->total;

            $this->datatables->from('jil_quotemjdetail'); 
           $this->datatables->join('jil_requirements', 'jil_requirements.rqm_id=jil_quotemjdetail.qud_requirementid', 'left');

               echo $this->datatables->generate();

           }

在你的控制器中使用这个，看看它是否工作

public function fetch_data() 
{ 
 $this->load->library("datatables");
 $query =  $this->datatables
        ->select('jil_requirements.*,count(jil_mrorfq.rfq_requirementid) as total,count(jil_quotemjdetail.qud_requirementid) as quotemjtotal,count(jil_quotejcdetail.qud_requirementid) as quotejctotal,count( jil_pocjdetail.pocd_requirementid) as pocjtotal,count(jil_pojmdetail.pojd_requirementid) as pojmtotal')
        ->from('jil_requirements')
        ->join('jil_users', 'jil_requirements.rqm_userid=jil_users.usr_id', 'left')
        ->join('jil_merchants', 'jil_requirements.rqm_createdempid=jil_merchants.mer_id', 'left')
        ->join('jil_mrorfq', 'jil_mrorfq.rfq_requirementid = jil_requirements.rqm_id', 'left')
        ->join('jil_quotemjdetail', 'jil_quotemjdetail.qud_requirementid = jil_requirements.rqm_id', 'left')
        ->join('jil_pocjdetail', 'jil_pocjdetail.pocd_requirementid = jil_requirements.rqm_id', 'left')
        ->join('jil_pojmdetail', 'jil_pojmdetail.pojd_requirementid = jil_requirements.rqm_id', 'left')
        ->where('jil_requirements.rqm_permission!=', '4');  
    echo $this->datatables->generate();
}

不了解数据库查询要求。但我猜你在找这样的东西：。。与此问题无关，您可以使用表的联接，而不是在循环中调用多个查询。但我想从其他表的结果中获取结果。如果这样，您可以使用查询。链接指向你的要求吗？@KiranKrishnan是的，我的要求。你能帮忙吗？是的，我确实加入了，但我不知道这个转换：（你确定吗？关于这一点？我不明白你想用这些查询来实现什么。你能解释一下吗…所以，我可以帮你…我理解每个单独的表查询，但为什么你要把它们放在一起。内部查询取决于每个表查询。）result@Angel现在检查仅用于测试目的，使用我更新的代码i它给了您想要的输出吗？我正在处理您的复杂结构，首先让它看起来简单，然后我们将把它转换为点燃的数据表…：）我在控制台中遇到了一些错误，比如未定义的函数order_by（） etc@AngelOkk然后删除order by并尝试…Ignited datatables不支持order by，因此请在您的jquery

“aaSorting”中使用它：[1，“asc”]]，

2小时后您是否有空？我将在晚上7点回来？如果您有时间，请准时来
