本文以實(shí)例形式講述Thinkphp實(shí)現(xiàn)的包括用戶的注冊(cè)、登錄以及留言等功能，這里需要大家注意的是，在存在用戶模型的情況下實(shí)例化一個(gè)用戶類的時(shí)候使用D方法來(lái)實(shí)現(xiàn)。
 
UserActiion.class.php頁(yè)面：

<?phpclass UserAction extends Action{public function add(){$user = D("user");$user->create();$result = $user->add();if($result){$this->assign("jumpUrl","__APP__/index/index");$this->success('注冊(cè)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");//$User->where('id=8')->find();這里的where 語(yǔ)句要注意一下，如果是其他字段的話后面一定要有單引號(hào)$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");$this->success('登陸成功！');}else{$this->assign("jumpUrl","__APP__/user/login");$this->error('密碼出錯(cuò)，請(qǐng)重新輸入！');}}else{$this->assign("jumpUrl","__APP__/user/login");$this->error('用戶名不存在！');}}public function loginout(){Cookie::delete('username');Cookie::delete('lastlogintime');$this->assign("jumpUrl","__APP__/index/index");$this->success('您已經(jīng)成功退出，歡迎您的下次登錄！');}} 

IndexAction.class.php頁(yè)面：

<?php// 本類由系統(tǒng)自動(dòng)生成，僅供測(cè)試用途class IndexAction extends Action{public function insert() {   $content = new ContentModel();$result = $content->create();if(!$result){$this->assign("jumpUrl","__URL__/index");$this->error($content->getError());//如果創(chuàng)建失敗，表示驗(yàn)證沒有通過，輸出錯(cuò)誤信息}else{//驗(yàn)證通過，進(jìn)行其他操作$content->userid=Cookie::get('userid');$content->add();$this->assign("jumpUrl","__URL__/index");$this->success('添加成功！');}} // 數(shù)據(jù)查詢操作  public function index() {$content = new ContentModel();$list = $content->findAll();  //用戶的cookie$username = Cookie::get('username');$lastlogintime = Cookie::get('lastlogintime');$this->assign('list',$list);    $this->assign('title','我的首頁(yè)');$this->assign('username',$username);$this->assign('lastlogintime',$lastlogintime);$this->display();  } // 刪除操作public function delete(){$content = new ContentModel();$id = $_GET['id'];if($content->where("id=$id")->delete()){$this->assign("jumpUrl","__URL__/index");$this->success('刪除成功！');}else{$this->assign("jumpUrl","__URL__/index");$this->error('刪除失?。?);}} // 編輯操作public function edit(){$content = new ContentModel();$id = $_GET['id'];if($id != ''){//$data = $content->select($id);$data = $content->where("id=$id")->select();if(!empty($data)){$this->assign('data',$data);}else{echo "數(shù)據(jù)為空！";}}$this->assign('title','編輯頁(yè)面');$this->display();}// 更新操作public function update(){$content = new ContentModel();//直接使用create(),自動(dòng)會(huì)幫你進(jìn)行數(shù)據(jù)的傳值/*$content->create();$content->save(); // 根據(jù)條件保存修改的數(shù)據(jù)echo "更新數(shù)據(jù)成功！";*/// 使用post 傳值過來(lái)，進(jìn)行更新$id = $_POST['id'];if($id != ''){$data['id'] = $id;$data['title'] = $_POST['title'];$data['content'] = $_POST['content'];if($content->save($data))// 根據(jù)條件保存修改的數(shù)據(jù){$this->assign("jumpUrl","__URL__/index");$this->success('更新數(shù)據(jù)成功！');}else{$this->assign("jumpUrl","__URL__/index");$this->success('更新數(shù)據(jù)失??！');}}else{echo "保存數(shù)據(jù)失?。?;}}}?> 

ContentModel.class.php頁(yè)面：

<?phpclass ContentModel extends Model{/** 自動(dòng)驗(yàn)證* array(驗(yàn)證字段，驗(yàn)證規(guī)則，錯(cuò)誤提示，驗(yàn)證條件，附加規(guī)則，驗(yàn)證時(shí)間)*/ protected $_validate = array(array('title','require','標(biāo)題必須填寫!'),array('content','require','內(nèi)容必須填寫!'), );/* * 自動(dòng)填充* array(填充字段，填充內(nèi)容，填充條件，附加規(guī)則)*/protected $_auto = array(array('addtime','time',1,'function'),);}?>

UserModel.class.php頁(yè)面：

<?phpclass UserModel extends Model{protected $_validate = array(array('username','','帳號(hào)名稱已經(jīng)存在！',0,'unique',1), );  }?>

 
這里需要注意的是，使用自動(dòng)驗(yàn)證的時(shí)候 實(shí)例化時(shí)要用 $user = D("user") 而不能用 $user = M("user"),用M這種方法會(huì)報(bào)錯(cuò)，D函數(shù)用于實(shí)例化Model,M函數(shù)用戶實(shí)例化一個(gè)沒有模型的文件。
 
success.html頁(yè)面：
