我的观看页面..（我的编辑和删除按钮显示）

       <?php 
   $this->table->set_heading("Name","Nationality","Number of Guest","Date of Arrival","Package","Other Request","Delete Record","Edit");
   $qry = $this->db->get('booking');
   foreach ($qry->result() as $row) {
$this->table->add_row($row->name,$row->nationality,$row->number_of_guest,$row->date,$row->package,$row->request,anchor('site/delete/'.$row->id, 'Del'),anchor('site/update/'.$row->id, 'edit'));

  }
   echo $this->table->generate();

Answer 1

在codeignitor中，您可以通过提供表中现有记录的引用来更新任何记录。

$this->db->update('booking', $booking);

booking应该是您要更新的表格，$booking必须是包含字段名称和值的键/值对的数组。

检查表格的booking）字段名称是否与$booking中的密钥相同!!

Answer 2

您也可以尝试这种方式。

function update()
{
    $booking=array(
        'name'=>$this->input->post('name'),
        'nationality'=>$this->input->post('nationality'),
        'number_of_guest'=>$this->input->post('number_of_guest'),
        'date'=>$this->input->post('date'),
        'package'=>$this->input->post('package'),
        'request'=>$this->input->post('request')
        );

    $this->db->where('id', 1);
    $this->db->update('booking', $booking);
}

---------更新---

`    function update()
     {
        $booking=array(
        'name'=>$this->input->post('name'),
        'nationality'=>$this->input->post('nationality'),
        'number_of_guest'=>$this->input->post('number_of_guest'),
        'date'=>$this->input->post('date'),
        'package'=>$this->input->post('package'),
        'request'=>$this->input->post('request')
        );    
    $this->db->where('<primary_key>', <pri_key_value>);
    $error =  $this->db->update('<table_name>', $booking);`,

请运行并粘贴您在$error

中获得的内容

试试这段代码......这是我的代码，您可以根据自己的要求进行更改。

查看

<?php $id = "1" ?>
<?php echo form_open_multipart("testimonials_controller/testimonials_edit/$id");?>
    <table width="500" class="table" cellpadding="0" cellspacing="2" align="center">
        <tr>
            <td width="130" align="left">Author: </td>
            <td><?php echo form_input($title); ?></td>
        </tr>
        <tr>
            <td width="130" align="left">Content: </td>
            <td><?php echo form_textarea($content); ?></td>
            <script type="text/javascript">
            CKEDITOR.replace( 'contentbox' );
            </script>
        </tr>
        <tr>
            <td>&nbsp;</td>
            <td><?php echo form_submit('submit', 'Submit');?>
            </td>
        </tr>
    </table>
<?php echo form_close();?>

模型

function updatetestimonials($id, $data)
    {
        $this->db->where('id', $id);
        $this->db->update('testimonials', $data);
