数据表未显示在视图页面上

Question

我正在使用 CodeIgniter，Datatable 无法正常工作。我正在显示数据表中的所有记录。但它没有显示。我得到这样的视图页面。

我正在从我的模型中获取记录。模型没有问题。如果需要型号代码，请告诉我。

你能帮我解决这个问题吗？

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

     }

您不断地在控制器中覆盖相同的变量来构建数据，因此请将其更改为使用[] 来添加数据...

$arr_result = [];    // Initialise the array
foreach ($books as $key => $row) 
{
    $arr_result[] = array(
          // "Sr.No" => $n,
                "id" => base64_encode($this->encryption->encrypt($row->id)),
                "name" => $row->firstname.' ' .$row->lastname,
                "employee_id" => $row->employee_id,
                "mobileno" => $row->mobileno,
                "emp_designation" => $row->emp_designation,
                "emp_role_name" => $row->emp_role_name,
                "emp_teamLeader" => $row->team_leadername
    );

  }
 // Add to main data after loop has finished
 $data['data'] = $arr_result;
