嗨，我有此删除的东西，然后在Ajax上使用它来删除数据。我的问题是，它不会在数据库上删除，当我刷新浏览器时，数据保留时，有人可以帮助我弄清楚这件事吗？这是我的控制器下面的控制器
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
session_start();
class News_and_events extends CI_Controller {
public function __construct(){
parent::__construct();
$this->load->library('form_validation');
$this->load->model('admin_model', 'am');
}
public function index(){
if($this->session->userdata('logged_in')){
$this->data['title'] = 'News and Events | Spring Rain Global Consultancy Inc Admin Panel';
$this->data['logout'] = 'Logout';
$session_data = $this->session->userdata('logged_in');
$this->data['id'] = $session_data['id'];
$this->data['username'] = $session_data['username'];
$this->data['allData'] = $this->am->getAllData();
$this->load->view('pages/admin_header', $this->data);
$this->load->view('content/news_and_events', $this->data);
$this->load->view('pages/admin_footer');
}else{
redirect('login', 'refresh');
}
}
public function add(){
if($this->session->userdata('logged_in')){
$this->form_validation->set_rules('date', 'Date', 'trim|required|xss_clean');
$this->form_validation->set_rules('event', 'Event', 'trim|required|xss_clean');
$this->form_validation->set_rules('description', 'Description', 'trim|required|xss_clean');
if($this->form_validation->run() == FALSE){
$this->data['title'] = 'News and Events | Spring Rain Global Consultancy Inc Admin Panel';
$this->data['logout'] = 'Logout';
$session_data = $this->session->userdata('logged_in');
$this->data['id'] = $session_data['id'];
$this->data['username'] = $session_data['username'];
$this->data['allData'] = $this->am->getAllData();
$this->load->view('pages/admin_header', $this->data);
$this->load->view('content/news_and_events', $this->data);
$this->load->view('pages/admin_footer');
}else{
$array = array(
'Date' => $this->input->post('date'),
'Event' => $this->input->post('event'),
'Description' => $this->input->post('description')
);
$this->am->saveData($array);
$this->session->set_flashdata('add_another',1);
redirect('news_and_events', 'refresh');
}
}else{
redirect('homepage', 'refresh');
}
}
public function delete(){
$id = $this->uri->segment(2);
$this->am->delete($id);
redirect(base_url().'news-and-events');
}
}
和我的观点
<script type="text/javascript">
$(document).ready(function(){
$("#add_another").click(function(){
});
});
function goDelete(id){
var agree = confirm("Are you sure you want to delete this?");
if(agree){
$("#news-and-event"+id).fadeOut('slow');
$.post('<?php echo base_url().'news-and-events/delete/'?>', {id:id}, function(){
});
}else{
return false;
}
}
</script>
<div class="container" >
<br />
<br />
<br />
<ul id="nav">
<li><a href="<?php echo base_url().'homepage'?>" title="Home"><h4>Home</h4></a></li>
<li><a href="<?php echo base_url().'news-and-events'?>" title="News and Events"><h4>News and Events</h4></a></li>
<li><a href="" title="Activities"><h4>Activities</h4></a></li>
</ul>
<div class="starter-template">
<h1>News And Events</h1>
<?php if(!$this->session->flashdata('add_another')):?>
<form action="<?php echo base_url().'news-and-events/add'?>" method="post">
<?php echo validation_errors('<div class="error">', '</div>');?>
<table class="table-striped">
<tr>
<td>Date: </td>
<td><input type="text" id="datepicker" name="date" value="<?php echo set_value('date');?>" /></td>
</tr>
<tr>
<td> </td>
</tr>
<tr>
<td >Event: </td>
<td ><input type="text" name="event" value="<?php echo set_value('event');?>" /></td>
</tr>
<tr>
<td> </td>
</tr>
<tr>
<td width="20%">Description: </td>

</tr>
<tr>
<td width="20%"> </td>
<td><input type="submit" value="Add" class="btn btn-success" /></td>
</tr>
</table>
</form>
<?php else: ?>
<div id="add_another" style="float:left;">
<input type="button" value="Add Another" class="btn btn-primary" />
</div>
<?php endif; ?>
<br />
<br />
<table class="table" >
<tr>
<th>Date</th>
<th width="47%" >Event</th>
<th width="32%">Description</th>

<?php foreach($allData as $x => $allDatas): ?>
<tr id="news-and-event<?php echo $allDatas->id; ?>">

<td style="text-align:left;"><?php echo $allDatas->Event; ?></td>
<td style="text-align:left;"><?php echo $allDatas->Description; ?></td>
<td width="10%">
<a href="<?php echo base_url().'news-and-events/edit/id/'.$allDatas->id;?>">Edit</a> |
<a href="javascript:;" onclick="return goDelete('<?php echo $allDatas->id;?>');" >Delete</a>
</td>
</tr>
<?php endforeach; ?>
</table>
</div>
</div><!-- /.container -->
<script>
var date = new Date();
var currentMonth = date.getMonth();
var currentDate = date.getDate();
var currentYear = date.getFullYear();
$('#datepicker').datepicker({
minDate: new Date(currentYear, currentMonth, currentDate),
dateFormat: "yy-mm-dd"
});
</script>
和我的模型删除数据库
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
Class Admin_model extends CI_Model{
public function saveData($array){
$this->db->insert('news_and_updates', $array);
}
public function getAllData(){
return $this->db->order_by("Date", "desc")
->get('news_and_updates')
->result_object();
}
public function delete($id){
$this->db->where('id', $id)->delete('news_and_updates');
}
}
?>
im使用$ this-> uri->段（2）;有帮助吗？非常感谢谢谢
您正在通过POST发送数据，但是您正在尝试根据uri segment删除数据。而不是在控制器中尝试一下：
public function delete(){
$id = $this->input->post('id');
$this->am->delete($id);
redirect(base_url().'news-and-events');
}
