如何在具有相应ID的数据表子行中显示辅助记录？

标签： php mysql html5 codeigniter datatables

我正在使用CodeIgniter和带有子行的数据表。 我正在做的是，我有一个具有主要成员和次要成员的主表。主要成员可以使用member_type=1和次要成员member_type=2进行标识。两个成员都与关系表连接。我可以在数据表中显示具有主要成员和次要成员的记录。

现在我正在使用数据表子行插件（https://datatables.net/examples/api/row_details.html）。如果用户要检查特定主要成员的次要成员，则必须在列表中显示主要成员，然后单击加号图像，他们将获得次要成员列表。

因此输出将是

enter image description here

代码说明

现在，我从Listdetails_ajax（）调用两个模型。首先是主要记录（getTotalList_of_primary();），第二是次要记录（getTotalList_of_secondary()）。在第一个模型中，我获得了具有ID的主要详细信息，并将该ID传递给第二个模型，以获取与该ID相关的次要成员记录。

问题是

1）我正在获取数据表中的所有记录（我只需要主记录）

2）如何在数据表中分配子值？

您能帮我解决这个问题吗？ 控制器 

public function Listdetails_ajax(){  
   $draw = intval($this->input->get("draw"));
$start = intval($this->input->get("start"));
$length = intval($this->input->get("length"));
$books = $this->Search_model->getTotalList_of_primary();

$data['draw'] = 1;
$data['recordsTotal'] = count($books);
$data['recordsFiltered'] = count($books);
foreach ($books as $key => $row) 
{
    //print_r($row->customer_id);
    $arr_result = array(
                "member_id" => base64_encode($this->encryption->encrypt($row->member_id)),
                "profile_pic" => $row->profile_pic,
                "name" => $row->first_name.' ' .$row->last_name,
                "phone" => $row->phone,
                "chss_no" => $row->chss_no,
                "emp_id" => $row->emp_id,
                "address" => $row->address
                // "member_type" => $row->member_type
    );
     $data['data'][] = $arr_result;
     $books_of_secondary = $this->Search_model->getTotalList_of_secondary($row->customer_id);
     print_r($arr_result);
     foreach ($books_of_secondary as $key => $row) 
        {
            //print_r($row->customer_id);
            $arr_result2 = array(
                        "s_member_id" => base64_encode($this->encryption->encrypt($row->member_id)),
                        "s_profile_pic" => $row->profile_pic,
                        "s_name" => $row->first_name.' ' .$row->last_name,
                        "s_phone" => $row->phone,
                        "s_chss_no" => $row->chss_no,
                        "s_emp_id" => $row->emp_id,
                        "s_address" => $row->address
            );


            $data['data'][] = $arr_result2;
              print_r($arr_result2);
        }
  }
echo json_encode($data);
exit;
}

模型 

public function getTotalList_of_primary(){
      $this->db->select('*');
      $this->db->from('members');
      $this->db->where('member_type',1);
      $query = $this->db->get();
      $res   = $query->result();        
     return $res;
}
public function getTotalList_of_secondary($id){
      $this->db->select('*');
      $this->db->from('members'); 
      $this->db->join('relation_member', 'relation_member.secondary_member_id = members.member_id'); 
      $this->db->where('relation_member.primary_customer_id',$id);
      $query = $this->db->get();
      $res   = $query->result();
      return $res;
}

数据表 

function format ( d ) {
    // `d` is the original data object for the row
    return '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'+
        '<tr>'+

答案 0 :(得分：1)

按照第一个想法，使用详细信息弹出窗口，控制器将如下所示：

public function Listdetails_ajax(){  
   $draw = intval($this->input->get("draw"));
    $start = intval($this->input->get("start"));
    $length = intval($this->input->get("length"));
    $books = $this->Search_model->getTotalList_of_primary();

    $data['draw'] = 1;
    $data['recordsTotal'] = count($books);
    $data['recordsFiltered'] = count($books);
    foreach ($books as $key => $row) 
    {
        //print_r($row->customer_id);
        $arr_result = array(
                    "member_id" => base64_encode($this->encryption->encrypt($row->member_id)),
                    "profile_pic" => $row->profile_pic,
                    "name" => $row->first_name.' ' .$row->last_name,
                    "phone" => $row->phone,
                    "chss_no" => $row->chss_no,
                    "emp_id" => $row->emp_id,
                    "address" => $row->address
                    // "member_type" => $row->member_type
        );

         $array_secondary = array();
         $books_of_secondary = $this->Search_model->getTotalList_of_secondary($row->customer_id);
         foreach ($books_of_secondary as $key => $row) 
            {
                //print_r($row->customer_id);
                $arr_result2 = array(
                            "s_member_id" => base64_encode($this->encryption->encrypt($row->member_id)),
                            "s_profile_pic" => $row->profile_pic,
                            "s_name" => $row->first_name.' ' .$row->last_name,
                            "s_phone" => $row->phone,
                            "s_chss_no" => $row->chss_no,
                            "s_emp_id" => $row->emp_id,
                            "s_address" => $row->address
                );


                $array_secondary[] = $arr_result2;
            }
         $arr_result['secondary'] =  $array_secondary;  
         $data['data'][] = $arr_result;
      }
    echo json_encode($data);
    exit;
}

然后在format函数中，您将访问secondary字段以获取第二数组。也许像这样：

function format(d) {
    // d is the original data object for the row var val;
    if(d.secondary.length == 0) {
        return "There are no secondary members";
    }

    var display = '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'; 
    for (val of d.secondary) { 
        display += '<tr>' + '<td>Full name:</td>' + '<td>' + val.s_name + '</td>' + '</tr>' + '<tr>' + '<td>Mobile number:</td>' + '<td>' + val.s_phone + '</td>' + '</tr>';
    }
    display += '</table>';
    return display;
}
