本文以实例形式讲述ThinkPHP实现的包括用户的注册、登录以及留言等功能，这里需要大家注意的是，在存在用户模型的情况下实例化一个用户类的时候使用D方法来实现。
UserActiion.class.php页面：
<?php
class UserAction extends Action{
public function add(){
$user = D("user");
$user->create();
$result = $user->add();
if($result){
$this->assign("jumpUrl","__APP__/index/index");
$this->success('注册成功！');
}else{
//echo $user->getError();
$this->assign("jumpUrl","__APP__/user/register");
$this->error($user->getError());
}
}
public function register(){
$this->display();
}
public function login(){
$this->display();
}
public function checklogin(){
$username = $_POST['username'];
$passwd = $_POST['passwd'];
$user = D("user");
//$User->where('id=8')->find();这里的where 语句要注意一下，如果是其他字段的话后面一定要有单引号
$userinfo = $user->where("username ='$username'")->find();
if(!empty($userinfo)){
if($userinfo['passwd'] == $passwd){
Cookie::set('userid',$userinfo['id'],time()+3600*24);
Cookie::set('username',$username,time()+3600*24);
Cookie::set('lastlogintime',time(),time()+3600*24);
$this->assign("jumpUrl","__APP__/index/index");
$this->success('登陆成功！');
}else{
$this->assign("jumpUrl","__APP__/user/login");
$this->error('密码出错，请重新输入！');
}
}else{
$this->assign("jumpUrl","__APP__/user/login");
$this->error('用户名不存在！');
}
}
public function loginout(){
Cookie::delete('username');
Cookie::delete('lastlogintime');
$this->assign("jumpUrl","__APP__/index/index");
$this->success('您已经成功退出，欢迎您的下次登录！');
}
}
IndexAction.class.php页面：
<?php
// 本类由系统自动生成，仅供测试用途
class IndexAction extends Action{
public function insert() {
$content = new ContentModel();
$result = $content->create();
if(!$result){
$this->assign("jumpUrl","__URL__/index");
$this->error($content->getError());//如果创建失败，表示验证没有通过，输出错误信息
}else{//验证通过，进行其他操作
$content->userid=Cookie::get('userid');
$content->add();
$this->assign("jumpUrl","__URL__/index");
$this->success('添加成功！');
}
}
// 数据查询操作
public function index() {
$content = new ContentModel();
$list = $content->findAll();
//用户的cookie
$username = Cookie::get('username');
$lastlogintime = Cookie::get('lastlogintime');
$this->assign('list',$list);
$this->assign('title','我的首页');
$this->assign('username',$username);
$this->assign('lastlogintime',$lastlogintime);
$this->display();
}
// 删除操作
public function delete(){
$content = new ContentModel();
$id = $_GET['id'];
if($content->where("id=$id")->delete()){
$this->assign("jumpUrl","__URL__/index");
$this->success('删除成功！');
}else{
$this->assign("jumpUrl","__URL__/index");
$this->error('删除失败！');
}
}
// 编辑操作
public function edit(){
$content = new ContentModel();
$id = $_GET['id'];
if($id != '')
{
//$data = $content->select($id);
$data = $content->where("id=$id")->select();
if(!empty($data)){
$this->assign('data',$data);
}else{
echo "数据为空！";
}
}
$this->assign('title','编辑页面');
$this->display();
}
// 更新操作
public function update(){
$content = new ContentModel();
//直接使用create(),自动会帮你进行数据的传值
/*$content->create();
$content->save(); // 根据条件保存修改的数据
echo "更新数据成功！";*/
// 使用post 传值过来，进行更新
$id = $_POST['id'];
if($id != '')
{
$data['id'] = $id;
$data['title'] = $_POST['title'];
$data['content'] = $_POST['content'];
if($content->save($data))// 根据条件保存修改的数据
{
$this->assign("jumpUrl","__URL__/index");
$this->success('更新数据成功！');
}
else{
$this->assign("jumpUrl","__URL__/index");
$this->success('更新数据失败！');
}
}else
{
echo "保存数据失败！";
}
}
}
?>
ContentModel.class.php页面：
<?php
class ContentModel extends Model{
/*
* 自动验证
* array(验证字段，验证规则，错误提示，验证条件，附加规则，验证时间)
*/
protected $_validate = array(
array('title','require','标题必须填写!'),
array('content','require','内容必须填写!'),
);
/*
* 自动填充
* array(填充字段，填充内容，填充条件，附加规则)
*/
protected $_auto = array(
array('addtime','time',1,'function'),
);
}
?>
UserModel.class.php页面：
<?php
class UserModel extends Model{
protected $_validate = array(
array('username','','帐号名称已经存在！',0,'unique',1),
);
}
?>
这里需要注意的是，使用自动验证的时候 实例化时要用 $user = D("user") 而不能用 $user = M("user"),用M这种方法会报错，D函数用于实例化Model,M函数用户实例化一个没有模型的文件。
success.html页面：

<html>
<head>
