Question

当我尝试从数据库中的clients表中获取数据时，我遇到了这个问题

DataTables警告：table id = example - 第0行请求的未知参数“0”。有关此错误的详细信息，请参阅http://datatables.net/tn/4

这是我在Codeigniter中的控制器

class Clients extends CI_Controller  {

    function header()
    {
        $data['hms'] = $this->config->item('page_title');
        $this->load->view('header3',$data);
    }

    public function index()
    {

        //$this->datatables->select('*');
        //$this->datatables->from('bookitguests');
        //$data['clients'] = $this->datatables->generate();
        $data = "";
        $this->header();
        $this->load->view('all_guests',$data);
    }

    public function TableClients()
    {
        $this->datatables->select('name, surname, email')->from('bookitguests');
        echo $this->datatables->generate();
    }

}

这是我在Codeigniter中的视图（ps，我没有添加头文件，它太长了）

使用对象数组而不是二维数组时，需要显式指定列。

"columns": [
                { "data": "id" },
                { "data": "name" }
              ]
