关于购物车,这个是在电子商务方面使用的比较多,用户选择好自己的商品需要保存起来,最后去收银台,这很像我们实际生活的超市,所以我现来写一个简单的php购物车实例代码,比较详细只要一步步,处理好就ok了。
些购物车会用到php文件
main.php 显示商品
additem.php把商品加入购物车
cearcart.php删除购物车中的商品
shoppingcart.php 操作类
用户的php教程有
inventory
create table inventory (
product tinytext not null,
quantity tinytext not null,
id int(4) default 0 not null auto_increment,
description tinytext not null,
price float(10,2) default 0.00 not null,
category char(1) default not null,
key id (id),
primary key (id),
key price (price)
);
insert into inventory values (硬盘,5,1,80g,5600,1);
insert into inventory values (cpu,12,2,p4-2.4g,6600,1);
insert into inventory values (dvd-rom,7,3,12x,2000,1);
insert into inventory values (主板www.php100.com,3,4,asus,5000,2);
