Answer 1

在你的代码中试试这个

//view
<tbody>             
<?php for ($i = 0; $i < count($records); ++$i) { ?>
<tr>
<td><?php echo ($i+1); ?></td>
<td><?php echo $records[$i]->fname; ?></td>
<td><?php echo $records[$i]->lname; ?></td>
<td><?php echo $records[$i]->email; ?></td>                                 
<td><a href="<?php echo base_url().'welcome/row_delete?id='.$records[$i]->id;?>">Delete</a></td>                       <td><a href="">Edit</a></td>                                  
</tr>
<?php } ?>
</tbody>

确保将记录ID传递给视图，并在配置文件

上配置base_url

//controller
public function row_delete(){
if(isset($_GET['id'])){
$id=$_GET['id'];
$this->load->model('Model');
$this->mod1->row_delete($id);
redirect($_SERVER['HTTP_REFERER']);}
}

//model
public function delete_row()
{
$this->db->where('id', $id);
$this->db->delete('register');
}

Answer 2

只需将参数传递给where函数和表名即可删除函数：

public function delete_row()
{
    // Set where
    $this->db->where('id', $id);

    // Run query
    return $this->db->delete('register');
}
