要一个简单的PHP购物网站源码

购物商城类的开源代码，可以用ECShop免费开源网店系统或者ThinkPHP shop开源商城系统来做，当然网上也有很多主题模板可以用。

ECShop比较适合来做简单网店系统，个人或者企业做销售产品用；

而TP shop可用于开发运营商、供货商、采购商、用户分销等多面向、多功能的商城系统，不过开发难度会稍高些，运作成本也会增高。

【高分】急求用php写的购物车代码！！！！！（十万火急）如果您提供的好用还有加分！！！

我也要弄一个这种购物车，

我去写个，贴出来，【嘿嘿，今天上午新写的】。

我懒得新建数据库，用的是我的数据库。

你按照我的改一下就能用了

本人水平有限，高手请指正。

你，大，爷的，虽然不咋地，保证能用

经过调试，

//$my-add_cart(45,3,"茶几系列");//新增购物

//$my-updata_cart(13,13,8); //更新购物

//$my-del_cart(12,5,'Guest'); //删除一种购物

//$my-empty_cart('Guest'); //清空购物车

$ok=$my-get_cart('Guest'); //返回购物车

这些都可用

CREATE TABLE IF NOT EXISTS `shopcart` (

`ID` int(10) NOT NULL auto_increment,

`usr` varchar(50) NOT NULL,

`price` decimal(50,2) NOT NULL default '0.00',

`pcid` varchar(100) NOT NULL,

`psum` decimal(50,2) NOT NULL default '0.00',

`payment` tinyint(1) NOT NULL,

`ptime` timestamp NOT NULL default CURRENT_TIMESTAMP,

PRIMARY KEY (`ID`)

product 里面用的ID CLASS1是

`ID` int(6) NOT NULL auto_increment,

`Class1` varchar(20) NOT NULL,

`Price` int(6) NOT NULL,

PHP 高手 请进来看下这段购物车代码

$sql="SELECT name,price FROM product WHERE id='$id'";

$id是变量，php中虽然双引号和单引号都能表示字符串，但是不同的是，单引号不能解析变量，也就是说'$aaaa'表示的就是字符串$aaaa，而不会解析字符串！

改为：

$sql="SELECT name,price FROM product WHERE id=$id";

请教关于PHP购物车代码的数据库表和字段

PHP Code

$current_url = base64_encode($url="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);

$results = $mysqli-query("SELECT * FROM cart ORDER BY id ASC");

if ($results) {

//fetch results set as object and output HTML

while($obj = $results-fetch_object())
