本文分两篇为大家介绍php实现购物车功能,具有一定的参考价值,相信大家一定喜欢。

1、需求分析

 我们需要找到一种将数据库连接到用户的浏览器的方法。用户能够按目录浏览商品。 用户应该能够从商品目录中选取商品以便此后的购买。我们也要能够记录他们选中的物品。 当用户完成购买,要合计他们的订单,获取运送商品细节,并处理付款。 创建一个管理界面,以便管理员在上面添加、编辑图书和目录。

2、解决方案

2.1 用户视图

2.2 管理员视图

2.3 Book-O-Rama中的文件列表

3、实现数据库3.1 创建book_sc数据库的SQL代码

CREATE DATABASE book_sc; #创建book_sc数据库 
 
USE book_sc; #使用book_sc数据库 
 
CREATE TABLE customers #创建用户表 
( 
 customerid INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, 
 name CHAR(60) NOT NULL, 
 address CHAR(80) NOT NULL, 
 city CHAR(30) NOT NULL, 
 state CHAR(10), 
 zip CHAR(10), 
 country CHAR(20) NOT NULL 
); 
 
CREATE TABLE orders #创建订单表 
( 
 orderid INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, 
 customerid INT UNSIGNED NOT NULL, 
 amount FLOAT(6,2), 
 date DATE NOT NULL, 
 order_status CHAR(10), 
 ship_name CHAR(60) NOT NULL, 
 ship_address CHAR(80) NOT NULL, 
 ship_city CHAR(30) NOT NULL, 
 ship_state CHAR(20), 
 ship_zip CHAR(10), 
 ship_country CHAR(20) NOT NULL 
); 
 
CREATE TABLE books #创建图书表 
( 
 isbn CHAR(13) NOT NULL PRIMARY KEY, 
 author CHAR(80), 
 title CHAR(100), 
 catid INT UNSIGNED, 
 price FLOAT(4,2) NOT NULL, 
 description VARCHAR(255) 
); 
 
CREATE TABLE categories #创建目录表 
( 
 catid INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, 
 catname CHAR(60) NOT NULL 
); 
 
CREATE TABLE order_items #订单物品表 
( 
 orderid INT UNSIGNED NOT NULL, 
 isbn CHAR(13) NOT NULL, 
 item_price FLOAT(4,2) NOT NULL, 
 quantity TINYINT UNSIGNED NOT NULL, 
 PRIMARY KEY(orderid,isbn) 
); 
 
CREATE TABLE admin #管理员表 
( 
 username char(16) NOT NULL PRIMARY KEY, 
 password CHAR(40) NOT NULL 
); 
 
GRANT SELECT,INSERT,UPDATE,DELETE 
on book_sc.* 
to book_sc@localhost IDENTIFIED by 'password'; 

3.2 数据库测试数据文档

USE book_sc; 
 
INSERT INTO books VALUES ('0672329166','Luke Welling and Laura Thomson','PHP and MySQL Web Development',1,49.99, 
'PHP & MySQL Web Development teaches the reader to develop dynamic, secure e-commerce web sites. You will learn to integrate and implement these technologies by following real-world examples and working sample projects.');

INSERT INTO categories VALUES (1,'Internet'); 
INSERT INTO categories VALUES (2,'Self-help'); 
INSERT INTO categories VALUES (5,'Fiction'); 
INSERT INTO categories VALUES (4,'Gardening'); 
 
INSERT INTO admin VALUES ('admin', sha1('admin')); 

4、实现在线目录

 $cat_array = get_categories(); //从数据库获取目录 
 
 display_categories($cat_array); //显示目录链接 
 
 if(isset($_SESSION['admin_user'])) //如果是管理员,显示管理员操作 
 display_button("admin.php","admin-menu","Admin Menu"); 
 do_html_footer(); //页尾 
"htmlcode">
function get_categories() //从数据库中获取目录列表 
 { 
 $conn = db_connect(); //连接数据库 
 $query = "select catid,catname from categories"; 
 $result = @$conn ->query($query); 
 if(!$result) //查询失败,返回false 
 return false; 
 $num_cats = @$result ->num_rows; 
 if($num_cats == 0) //数据库中无目录,返回false 
 return false; 
 $result = db_result_to_array($result); 
 return $result; 
 } 

4.3 output_fns.php文件中的函数display_categories()

 { 
 if(!is_array($cat_array)) 
 { 
 echo "<p>No categories currently available</p>"; 
 return; 
 } 
 echo "<ul>"; 
 foreach($cat_array as $row) 
 { 
 $url = "show_cat.php". $row['catid']; 
 $title = $row['catname']; 
 echo "<li>"; 
 do_html_URL($url,$title); 
 echo "</li>"; 
 } 
 echo "</ul>"; 
 echo "<hr/>"; 
 } 

4.4 db_fns.php文件中的函数db_result_to_array()

function db_result_to_array($result) //结果到数组 
 { 
 $res_array = array(); 
 
 for($count = 0; $row = $result ->fetch_assoc(); $count++) 
 $res_array[$count] = $row; 
 
 return $res_array;

 $result = @$conn ->query($query); 
 if(!$result) //查询失败,原因为查询出错 
 return false; 
 
 $num_cats = @$result ->num_rows; 
 
 if($num_cats == 0) //查询失败,原因为无目录 
 return false; 
 $row = $result ->fetch_object(); 
 return $row ->catname; 
 }

 $result = @$conn ->query($query); 
 if(!$result) //查询失败,原因为查询出错 
 return false; 
 
 $num_books = @$result ->num_rows; 
 
 if($num_books == 0) //查询失败,原因为无图书 
 return false; 
 
 $result = db_result_to_array($result); 
 return $result;

 { 
 echo "<table width = \"100%\" border=\"0\">"; 
 
 foreach($book_array as $row) 
 { 
 $url = "show_book.php". $row['isbn']; 
 echo "<tr><td>"; 
 // 如果图片存在 
 if(@file_exists("images/". $row['isbn'] .".jpg")) 
 { 
 $title = "<img src=\"images/". $row['isbn'] .".jpg\" style=\"border: 1px solid black\"/>"; 
 do_html_URL($url,$title); 
 } 
 else 
 echo " "; 
 
 echo "</td><td>"; 
 $title = $row['title'] ." by ". $row['author'];

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
