Php 什么'；我的代码出现在数据库中有什么问题？

请帮帮我，我的数据库是dbindosat，表是formpengajuan

<?php 
foreach($filedata as $data){ 
?>
<tr>
<td><?php echo $data-> kode; ?></td>
<td><?php echo $data-> instansi; ?></td>
<td><?php echo $data-> alamatinstansi; ?></td>
<td><?php echo $data-> judulkegiatan; ?></td>
<td><?php echo $data-> jeniskegiatan; ?></td>
<td><?php echo $data-> dana; ?></td>
<td><?php echo $data-> tanggalacara; ?></td>
<td><?php echo $data-> kontak; ?></td>
<td><?php echo $data-> email; ?></td>
</tr>
<?php } ?>

我的控制器

    <?php 


class Crud extends CI_Controller{

    function __construct(){
        parent::__construct();      
        $this->load->model('m_data');
        $this->load->helper('url');

    }

    function index(){
        $data['filedata'] = $this->m_data->tampil_data()->result();
        $this->load->view('viewdata',$data);
    }
...

<?php 
foreach($filedata as $data){ 
?>
<tr>
<td><?php echo $data-> kode; ?></td>
<td><?php echo $data-> instansi; ?></td>

数据库未显示，请帮助。。谢谢

您必须更改控制器中的这行代码：

<?php 
foreach($filedata as $data){ 
?>
<tr>
<td><?php echo $data-> kode; ?></td>
<td><?php echo $data-> instansi; ?></td>
<td><?php echo $data-> alamatinstansi; ?></td>
<td><?php echo $data-> judulkegiatan; ?></td>
<td><?php echo $data-> jeniskegiatan; ?></td>
<td><?php echo $data-> dana; ?></td>
<td><?php echo $data-> tanggalacara; ?></td>
<td><?php echo $data-> kontak; ?></td>
<td><?php echo $data-> email; ?></td>
</tr>
<?php } ?>

 function index(){
    $data['filedata'] = $this->m_data->tampil_data();
    $this->load->view('viewdata',$data);
}

在您的模型代码中：

<?php 
foreach($filedata as $data){ 
?>
<tr>
<td><?php echo $data-> kode; ?></td>
<td><?php echo $data-> instansi; ?></td>
<td><?php echo $data-> alamatinstansi; ?></td>
<td><?php echo $data-> judulkegiatan; ?></td>
<td><?php echo $data-> jeniskegiatan; ?></td>
<td><?php echo $data-> dana; ?></td>
<td><?php echo $data-> tanggalacara; ?></td>
<td><?php echo $data-> kontak; ?></td>
<td><?php echo $data-> email; ?></td>
</tr>
<?php } ?>

   function tampil_data(){
       return $this->db->get('formpengajuan')->result();
   }

如果您没有自动加载数据库，则通过添加以下行将其加载到控制器中

<?php 
foreach($filedata as $data){ 
?>
<tr>
<td><?php echo $data-> kode; ?></td>
<td><?php echo $data-> instansi; ?></td>
<td><?php echo $data-> alamatinstansi; ?></td>
<td><?php echo $data-> judulkegiatan; ?></td>
<td><?php echo $data-> jeniskegiatan; ?></td>
<td><?php echo $data-> dana; ?></td>
<td><?php echo $data-> tanggalacara; ?></td>
<td><?php echo $data-> kontak; ?></td>
<td><?php echo $data-> email; ?></td>
</tr>
<?php } ?>

 function __construct(){  
    parent::__construct(); 
    $this->load->database();
 }

让我知道这些更改是否帮助您解决了问题

<?php 
foreach($filedata as $data){ 
?>
<tr>
<td><?php echo $data-> kode; ?></td>
<td><?php echo $data-> instansi; ?></td>
<td><?php echo $data-> alamatinstansi; ?></td>
<td><?php echo $data-> judulkegiatan; ?></td>
<td><?php echo $data-> jeniskegiatan; ?></td>
<td><?php echo $data-> dana; ?></td>
<td><?php echo $data-> tanggalacara; ?></td>
<td><?php echo $data-> kontak; ?></td>
<td><?php echo $data-> email; ?></td>
</tr>
<?php } ?>
