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。
