我想将 codeigniter 中的这个查询转换为 Ignated 数据表查询答案

【问题标题】：I want to convert this query in codeigniter to Ignited datatable query我想将 codeigniter 中的这个查询转换为 Ignated 数据表查询

【问题描述】：

我不知道如何将这个长模型函数转换为点燃的数据表查询。我已经用点燃的数据表完成了小的选择功能。有人知道吗？？？
我不知道如何隐藏它。有什么功能可以做到吗？

   public function fetch_data() {

              $this->db->from('jil_requirements');

【问题讨论】：

不了解数据库查询要求。但我猜你正在寻找这样的东西：github.com/IgnitedDatatables/Ignited-Datatables、ahmed-samy.com/…、stackoverflow.com/questions/11355542/… .. 与这个问题无关，你可以使用表的连接而不是在循环中调用多个查询。
但我想从另一个表的结果中获取结果
如果是这样，您可以使用查询。链接是否指向您的要求？
@KiranKrishnan 是的，我的要求。你能帮忙吗？
是的，我加入了，但我不知道这个转换:(

【解决方案2】：

首先你必须加载被点燃的dataTables库。

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

或

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

之后，全部更改

      $this->db->

在您的查询中

     $this->datatables

最后你必须使用它来编码 json 数组中的数据

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

              $row->pojm_total = $query6->pojmtotal;

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

           }

【讨论】：

你确定吗？关于这个？
我不明白你想通过所有这些查询一起实现什么。
你能解释一下......所以，我可以帮忙......我理解每个单独的表查询，但你为什么要把所有这些放在一起。
内部查询取决于该 foreach 结果

【解决方案3】：

在你的控制器中使用它，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();
}

【讨论】：

@Angel 现在检查仅用于测试目的，仅使用我更新的代码是否为您提供所需的输出？我正在研究你的复杂结构，先给它一个简单的外观，然后我们将其转换为 Ignited 数据表...... :)
我在控制台中遇到了一些错误，例如未定义的函数 order_by() 等
@Angel Okk 然后删除 order by 并尝试... 点燃的数据表不支持 order_by 所以在你的 jquery 中使用它"aaSorting": [[1, "asc"]],
2小时后有空吗？
我会在晚上 7 点回来吗？如果你有时间，请到时候来
