㈠ 【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,
`pid` int(5) NOT NULL,
`pname` varchar(100) NOT NULL,
`ptl` int(3) 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`)
)
proct 里面用的ID CLASS1是
`ID` int(6) NOT NULL auto_increment,
`Class1` varchar(20) NOT NULL,
`Price` int(6) NOT NULL,
㈡ 求PHP里的TP5的购物车代码
可以参考如下代码
<?php
classCartextendsThink{
//当前购物车名
public$sessionName;
//购物车总价格
public$totalPrice
publicfunction__construct($sessionName)
{
$this->sessionName=$sessionName;
if(!isset($_SESSION[$this->sessionName]))
{
$_SESSION[$this->sessionName]="";
}
}
//获取购物车的信息
publicfunctiongetCart(){
$cur_cart_array=$_SESSION[$this->sessionName];
return$cur_cart_array;
}
//获取购物车商品清单
publicfunctiongetCartList()
{
$cur_cart_array=$_SESSION[$this->sessionName];
if($cur_cart_array!="")
{
$mode_goods_data=M("goods_data");
$len=count($cur_cart_array);
for($i=0;$i<$len;$i++)
{
$goodsid=$cur_cart_array[$i]["id"];
$num=$cur_cart_array[$i]["num"];
$query="select(selectsfilenamefromgoods_picwheregoodsid=a.goodsidorderbysnodesclimit0,1)assfilename,b.clsnameasclsname,a.goodsidasgoodsid,a.goodsnameasgoodsname,a.PriceasPrice,a._dataaleftjoingoods_clsbona.Clsid=b.clsidwherea.goodsid=$goodsid";
$list=$mode_goods_data->query($query);
$list[0]["qty"]=$num;
$list[0]["amount"]=$num*$list[0]["Price"];
$cartList[$i]=$list[0];
$totalPrice+=$list[0]["amount"];
}
//返回商品总价格
$this->totalPrice=$totalPrice;
return$cartList;
}
}
//加入购物车,购物车的商品id和购物车的商品数量
publicfunctionaddcart($goods_id,$goods_num){
$cur_cart_array=$_SESSION[$this->sessionName];
if($cur_cart_array=="")
{
$cart_info[0]["id"]=$goods_id;//商品id保存到二维数组中
$cart_info[0]["num"]=$goods_num;//商品数量保存到二维数组中
$_SESSION[$this->sessionName]=$cart_info;
}
else
{
//返回数组键名倒序取最大
$ar_keys=array_keys($cur_cart_array);
$len=count($ar_keys);
$max_array_keyid=$ar_keys[$len-1]+1;
//遍历当前的购物车数组
//遍历每个商品信息数组的0值，如果键值为0且货号相同则购物车该商品已经添加
$is_exist=$this->isexist($goods_id,$goods_num,$cur_cart_array);
if($is_exist==false)
{
$cur_cart_array[$max_array_keyid]["id"]=$goods_id;
$cur_cart_array[$max_array_keyid]["num"]=$goods_num;
$_SESSION[$this->sessionName]=$cur_cart_array;
}
else
{
$arr_exist=explode("/",$is_exist);
$id=$arr_exist[0];
$num=$arr_exist[1];
$cur_cart_array[$id]["num"]=$num;
$_SESSION[$this->sessionName]=$cur_cart_array;
}
}
}
//判断购物车是否存在相同商品
publicfunctionisexist($id,$num,$array)
{
$isexist=false;
foreach($arrayas$key1=>$value)
{
foreach($valueas$key=>$arrayid)
{
if($key=="id"&&$arrayid==$id)
{
$num=$value["num"]+$num;
$isexist=$key1."/".$num;
}
}
}
return$isexist;
}
thinkphp开发使得我们比较容易的去进行了
//从购物车删除
publicfunctiondelcart($goods_array_id){
//回复序列化的数组
$cur_goods_array=$_SESSION[$this->sessionName];
//删除该商品在数组中的位置
unset($cur_goods_array[$goods_array_id]);
$_SESSION[$this->sessionName]=$cur_cart_array;
//使数组序列化完整的保存到cookie中
}
//清空购物车
publicfunctionemptycart(){
$_SESSION[$this->sessionName]="";
}
//修改购物车货品数量
publicfunctionupdate_cart($up_id,$up_num){
//回复序列化的数组
$cur_goods_array=$_SESSION[$this->sessionName];
$cur_goods_array[$up_id]["num"]=$up_num;
$_SESSION[$this->sessionName]=$cur_cart_array;
}
}
?>
㈢ 一个最简单的用PHP实现购物车功能，请高手指点
这个感觉用cookie就好了啦
你一步步的跟踪一下，看看是哪儿没拿到值，可以在foreach之前把session的数组转存到一个变量里
㈣ 请教关于PHP购物车代码的数据库表和字段
