I want to convert this query to codeigniter in an Ignited datatable query

I don't know how to convert this long model function to a flammable datatable query. I made small selection functions with inflamed datatables. No one knows??? I have no idea how to hide it. Are there any features for this?

   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->join('jil_merchants', 'jil_requirements.rqm_createdempid=jil_merchants.mer_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'); 
                $this->db->from('jil_mrorfq'); 
               $this->db->join('jil_requirements', 'jil_requirements.rqm_id=jil_mrorfq.rfq_requirementid', 'left'); 
               $this->db->where('jil_requirements.rqm_id',$row->rqm_id);
                  $query2= $this->db->get()->row_object();
                 $row->total_count = $query2->total;

First you need to load the downloaded dataTables library.

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

OR

add it to the autoloader to load automatically when the Codeigniter application starts.

After that, change everything

      $this->db->

in your inquiries on

     $this->datatables

Finally, you should use this to encode data in a json array

      $this->datatables->generate();

,

UPDATE

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'); 
           $this->datatables->where('jil_requirements.rqm_id',$row->rqm_id);
              $query3= $this->datatables->get()->row_object();
              $row->quotemj_total = $query3->quotemjtotal;

               $this->datatables->select('count(jil_quotejcdetail.qud_requirementid) as quotejctotal'); 
            $this->datatables->from('jil_quotejcdetail'); 
           $this->datatables->join('jil_requirements', 'jil_requirements.rqm_id= jil_quotejcdetail.qud_requirementid', 'left'); 
           $this->datatables->where('jil_requirements.rqm_id',$row->rqm_id);
              $query4= $this->datatables->get()->row_object();
              $row->quotejc_total = $query4->quotejctotal;

                $this->datatables->select('count( jil_pocjdetail.pocd_requirementid) as pocjtotal'); 
            $this->datatables->from('jil_pocjdetail'); 
           $this->datatables->join('jil_requirements', 'jil_requirements.rqm_id=  jil_pocjdetail.pocd_requirementid', 'left');

              $row->pocj_total = $query5->pocjtotal;

               $this->datatables->select('count(jil_pojmdetail.pojd_requirementid) as pojmtotal');

              $query6= $this->datatables->get()->row_object();
              $row->pojm_total = $query6->pojmtotal;

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

           }

Use this in your controller and see if it works

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();
}
