PHP基础示例:商品信息管理系统v1.1

实现目标:使用php和mysql写一个商品信息管理系统,并带有购物车功能

一、创建数据库和表

  1.创建数据库和表:demodb

  2.创建表格:goods

  字段:商品编号,商品名称,商品类型,商品图片,单价,商品描述,库存量,添加时间

二、创建php文件编写代码(以下为要创建的php文件及其用途)

  add.php  商品添加页面

  edit.php      商品信息编辑表单页

  index.php  商品信息浏览页

  action.php  执行商品信息添加和修改及删除等操作处理

  dbconfig.php  公共配置文件,数据库连接配置信息

  menu.php  网站公共导航栏

  uploads/   上传图片的存放目录

  function.php 公共函数库文件:图片信息的上传,等比缩放等处理函数

  addCart.php 添加购物车信息的操作(向SESSION放入要购买的信息)

  myCart.php  实现了购物车信息的浏览操作,并且实现商品信息的统计(小计和总价)

  clearCart.php 实现了购物车信息的单个商品删除或清空购物车操作

  updateCart.php  修改购物车中商品的数量,防止过小约束

 

各php文件关系图示:

好,那下面是代码部分:

首先是建表语句:
