写了个PHP网站,但是每次只能添加一条信息,即只能添加和显示第一条数据,以后添加的数据都看不到;
代码如下:

<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><title>添加商品</title><link rel="stylesheet" type="text/css" href="css/font.css"><style type="text/css"><!--.style1 {color:

回复讨论(解决方案)

为了方便分析,请贴出savenewgoods.php

是不是id什么重复了呀 打印一下提交的数据是否接收到了

<?php            $sql=mysql_query("select * from tb_type order by id desc",$conn);            $info=mysql_fetch_array($sql);            if($info==false)            {              echo "请先添加商品类型!";            }

while($info = mysql_fetch_array($sql)){}

晚上会全部贴出,谢谢大家了

PHP code?1234567$info=mysql_fetch_array($sql); ……

138以下行重写么?最后得while替换到哪里 谢谢

不知道 只能显示第一条数据 是什么意思
你只给出了发布新商品的表单,并没有显示数据的代码

中午我会补贴下,到时候希望能够帮忙 谢谢

我在下面贴了 savenewgoods.php和 changegoods.php 还有conn.php的代码 麻烦大大们看下了……
目前的问题是 后台只能添加一条数据 以后再怎么添加都看不到,但是类别添加却可以看到。。。

不知道 只能显示第一条数据 是什么意思
你只给出了发布新商品的表单,并没有显示数据的代码

我已经贴上来了 谢谢了

是指每次向数据库里只能插一条信息么?
我简单测试了一下应该没有问题的,是不是建表的primary key没有设置对?
