Question

我正在尝试通过ID删除数据，但是它不起作用。我有这样的代码。

控制器：

public function delete()
{
    if (isset($_GET['del'])) {
        $ii = $this->input->post('id');
        $this->P6_model->delete($ii);
        $this->load->view('p6home');
    }
}

型号：

public function delete($i)
{
    return $this->db->delete('contacts', array('id' => $i));
}

路线：

$route['deldata'] = 'p6/delete';

查看：

                foreach ($contacts as $data) {
            ?>
                <tr>
                    <input type="hidden" name="id" value="<?=$data->id?>"/>
                    <td data-label="Name"><?=$data->name?></td>
                    <td data-label="address"><?=$data->address?></td>
                    <td data-label="phone"><?=$data->phone?></td>
                    <td>
                        <button class="positive ui button">Update</button>
                        <button class="negative ui button" onclick="return confirm('Are you sure?')" name="del" href="deldata">Delete</button>
                    </td>
                </tr>
            <?php
            }
            ?>

谢谢。

您必须声明了base_url，对吗？在链接中使用该链接重定向页面。另外，在URL本身中提供get参数。没有表单，POST将无法工作。这应该为您工作。
查看：

<?php 
    foreach ($contacts as $data) {
?>
    <tr>
        <td data-label="Name"><?=$data->name?></td>
        <td data-label="address"><?=$data->address?></td>
        <td data-label="phone"><?=$data->phone?></td>
        <td>
            <button class="positive ui button">Update</button>
            <button class="negative ui button" onclick="return confirm('Are you sure?')" name="del" href="<?php echo base_url('deldata')."/$data->id"; ?>">Delete</button>
        </td>
    </tr>
<?php
    }
?>

控制器：

public function delete($id)
{
    $this->P6_model->delete($id);
    $this->load->view('p6home');    //instead of loading the view here, try redirecting to a controller function and load the view there.
}

使用代码点火器删除数据不起作用
