为什么我的更新不成功！？
论坛上没有比较详细的说明，呵，我自己写的，玩玩，刚入门，不懂，请大家照顾下控制器：ecms.php
<?php
class Ecms extends Controller {
function Ecms()
{
parent::Controller();
$this->load->helper('url');
$this->load->helper('form');
}
function index()
{
$this->load->database();
$data['title']="ECMS";
$data['heading']="报障内容系统";
$this->load->view('ecms_view',$data);
}
function product()
{
$this->load->database();
$data['title']="报障产品维护";
$data['heading']="报障产品";
$data['query']=$this->db->get('product');
$this->load->view('product_view',$data);
}
function product_insert()
{
$this->load->database();
$this->db->insert('product',$_POST);
redirect('ecms/product/');
}
function product_edit()
{
$this->load->database();
$data['title']="更新报障产品";
$data['heading']="更新报障产品";
$this->db->where('id',$this->uri->segment(3));
$data['query']=$this->db->get('product');
$this->load->view('product_edit',$data);
}
function product_update()
{
$this->load->database();
$this->db->set('products',$_POST['products_name']);
$this->db->where('id',$this->uri->segment(3));
$this->db->update('product');
redirect('ecms/product/');
}
}
?>
VIEW：product_edit.php
<html>
<head>
<title><?=$title?></title>
</head>
<body>
<h1><?=$heading?></h1>
<p><?=anchor('ecms','返回主页');?></p>
<?=form_open('ecms/product_update');?>
<?php if($query->num_rows()==1):?>
<?php foreach($query->result() as $row):?>
<p>报障产品：<input type="text" value=<?=$row->products;?> name="products_name"/></p>
<?php endforeach;?>
<input type="submit" value="更新数据"/>
<?php else:?>
<?php echo"传递的参数数量错误，请返回！";?>
<?php endif;?>
</form>
</body>
</html>
为什么我的update不成功呢？此页面没有报错！请教高人！！！
[ 本帖最后由 tanqimin 于 2008-1-25 22:38 编辑 ] 把 redirect 去掉看看有什么错误提示？ 找到原因了，呵呵，原来是不能获取id值
谢谢HEX
