本文以實例形式講述ThinkPHP實現的包括用戶的注冊、登錄以及留言等功能,這裡需要大家注意的是,在存在用戶模型的情況下實例化一個用戶類的時候使用D方法來實現。
UserActiion.class.php頁面:
<?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('注冊成功!'); }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();這裡的where 語句要注意一下,如果是其他字段的話後面一定要有單引號 $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,請重新輸入!'); } }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('您已經成功退出,歡迎您的下次登錄!'); } }
IndexAction.class.php頁面:
<?php // 本類由系統自動生成,僅供測試用途 class IndexAction extends Action{ public function insert() { $content = new ContentModel(); $result = $content->create(); if(!$result){ $this->assign("jumpUrl","__URL__/index"); $this->error($content->getError());//如果創建失敗,表示驗證沒有通過,輸出錯誤信息 }else{//驗證通過,進行其他操作 $content->userid=Cookie::get('userid'); $content->add(); $this->assign("jumpUrl","__URL__/index"); $this->success('添加成功!'); } } // 數據查詢操作 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'); $this->assign('username',$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('刪除失敗!'); } } // 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 "數據為空!"; } } $this->assign('title','編輯頁面'); $this->display(); } // 更新操作 public function update(){ $content = new ContentModel(); //直接使用create(),自動會幫你進行數據的傳值 /*$content->create(); $content->save(); // 根據條件保存修改的數據 echo "更新數據成功!";*/ // 使用post 傳值過來,進行更新 $id = $_POST['id']; if($id != '') { $data['id'] = $id; $data['title'] = $_POST['title']; $data['content'] = $_POST['content']; if($content->save($data))// 根據條件保存修改的數據 { $this->assign("jumpUrl","__URL__/index"); $this->success('更新數據成功!'); } else{ $this->assign("jumpUrl","__URL__/index"); $this->success('更新數據失敗!'); } }else { echo "保存數據失敗!"; } } } ?>
ContentModel.class.php頁面:
<?php class ContentModel extends Model{ /* * 自動驗證 * array(驗證字段,驗證規則,錯誤提示,驗證條件,附加規則,驗證時間) */ protected $_validate = array( array('title','require','標題必須填寫!'), array('content','require','內容必須填寫!'), ); /* * 自動填充 * array(填充字段,填充內容,填充條件,附加規則) */ protected $_auto = array( array('addtime','time',1,'function'), ); } ?>
UserModel.class.php頁面:
<?php class UserModel extends Model{ protected $_validate = array( array('username','','帳號名稱已經存在!',0,'unique',1), ); } ?>
這裡需要注意的是,使用自動驗證的時候 實例化時要用 $user = D("user") 而不能用 $user = M("user"),用M這種方法會報錯,D函數用於實例化Model,M函數用戶實例化一個沒有模型的文件。
