web典型应用

关于web 典型应用;

此处是以传智的论坛为模板写的项目;具有注册用户,登录,发帖,回复等功能;

第一个功能的实现:用户的注册

先是创建MySQL数据表:

1 create table user(
2     user_id int unsigned primary key auto_increment comment '主键ID',
3     user_name varchar(20) not null unique key comment '用户名',
4     user_password char(32) not null comment '用户密码'
5 );

查看表结构:

 1 <?php
 2 /**
 3  * 项目初始化文件;
 4  */
 5 
 6 //1.设置响应头(设置文字编码)
 7 header("Content-type:text/html;charset=utf-8");
 8 //定义常量目录;
 9 //定义根目录常量;
10 define("DIR_ROOT", str_replace('\','/',__DIR__).'/');
11 //定义配置文件目录常量;
12 define("DIR_CONFIG", DIR_ROOT.'config/');
13 //定义核心文件目录常量;
14 define("DIR_CORE",DIR_ROOT.'core/');
15 //定义逻辑处理目录常量;
16 define("DIR_MODEL",DIR_ROOT.'model/');
17 //定义模板文件目录常量;
18 define("DIR_VIEW",DIR_ROOT.'view/');
19 //定义公开文件目录常量;
20 define("DIR_PUBLIC",'/public');

加载初始视图文件index.php

1 <?php
2 //1,加载项目初始化文件;
3 include './init.php';
4 
5 //2.加载视图文件;
6 include DIR_VIEW.'index.html';

编写index.html文件:

效果如图:

创建register.php文件

用于加载视图文件;

1 <?php 
2 //1加载项目初始化文件;
3 include '../init.php';
4 
5 //2.加载视图文件;
6 include DIR_VIEW .'register.html';

编写register.html文件:
