未定义属性：codeigniter中的stdClass :: $ datetime

Question

我想显示基于已登录用户的数据，但根据用户显示错误，而根据用户显示第1行（id_laporan），而其余部分不显示。

型号：

class user_model extends CI_Model{

    public function tampil_data()
    {
        $sesdata = $this->session->userdata('ses_user');
        $this->db->select('id_laporan','datetime','jenis_keg','object');
        $this->db->where('username',$sesdata );
        $this->db->from('tb_laporan');
        $query = $this->db->get();          

        return $query;
    }
}

控制器

class user_data extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->model('user_model');
    }
    public function index(){
        $kon['konten'] = 'view_laporan/index';
        $kon['tampil_data']=$this->user_model->tampil_data();
        $this->load->view('view_laporan/index',$kon);
    }
}

查看首页

 <div id="content-wrapper" class="container Home">

      <?php $this->load->view($konten); ?>

  </div>

在家用电脑中，是view_laporan / tampil

            <table id="tampil_data" class="table table-hover">
                <thead>
                    <tr>
                        <th>id laporan</th>
                        <th>waktu</th>
                        <th>jenis kegiatan</th>
                        <th>object</th>
                    </tr>
                <?php 
                   if($tampil_data->num_rows() > 0)  
                   {  
                        foreach($tampil_data->result() as $row)  
                        {  
                   ?>  
                        <tr>  
                             <td><?php echo $row->id_laporan; ?></td>  
                             <td><?php echo $row->datetime; ?></td>   
                             <td><?php echo $row->jenis_keg; ?></td>  
                             <td><?php echo $row->object; ?></td>    
                        </tr>  
                   <?php       
                        }  
                   }  
                   else  
                   {  
                   ?>  
                        <tr>  
                             <td colspan="5">No Data Found</td>  
                        </tr>  
                   <?php  
                   }  
                   ?>  
                </thead>
                <tbody></tbody>
            </table>
