本文实例讲述了ThinkPHP基本的增删查改操作,是ThinkPHP项目开发中最常用的基础操作,有着十分重要的应用价值。现将完整的实例代码与大家分享,希望能对大家有所帮助。具体如下:
一、表aoli_user字段设置:
表aoli_user主要有以下几个字段:
id username password createtime createip
二、view模板部分
1.用户首页模板:
aoli/Home/Tpl/default/User/index.html页面代码如下:

< form action = "__URL__/add" method = "post" > 用户名:< input type = "text" name = "username" />< br /> 密码:< input type = "password" name = "password" />< br /> 重复密码:< input type = "repassword" name = "repassword" />< br /> < input type = "submit" value = "注册" /> </ form > < volist name = "alist" id = "vo" > < li >< span >ID:</ span >{$vo['id']}< span >用户名:</ span >{$vo['username']}< span >注册ip:</ span >{$vo['createip']}< a href = "__URL__/del/id/{$vo['id']}" >删除</ a > < a href = "__URL__/edit/id/{$vo['id']}" >编辑</ a ></ li > </ volist > |
2.用户编辑模板:
