本文实例讲述了PHP实现的简单留言板功能。分享给大家供大家参考，具体如下：
入口文件 文件名 index.php
<?php// 应用入口文件// 检测PHP环境if(version_compare(PHP_VERSION,"5.3.0","<")) die("require PHP > 5.3.0 !");// 开启调试模式 建议开发阶段开启 部署阶段注释或者设为falsedefine("APP_DEBUG",True);//开发调试模式//define("APP_DEBUG",false);//生产模式// 定义应用目录define("APP_PATH","./Message/");// 引入ThinkPHP入口文件require "./ThinkPHP/ThinkPHP.php";// 亲^_^ 后面不需要任何代码了 就是如此简单配置文件 文件名 config.php
<?phpreturn array( //"配置项"=>"配置值" "SHOW_PAGE_TRACE"=>true, "DB_TYPE" => "mysqli", // 数据库类型 "DB_HOST" => "127.0.0.1", // 服务器地址 "DB_NAME" => "msg", // 数据库名 "DB_USER" => "root", // 用户名 "DB_PWD" => "root", // 密码 "DB_PORT" => "3306", // 端口 "DB_PREFIX" => "ms_", // 数据库表前缀);
控制器 文件名 MsgController.class.php
<?phpnamespace HomeController;use ThinkController;use ThinkModel;class MsgController extends Controller{ public function index(){ $msg = D("Msg"); $info = $msg->order("id DESC")->select(); $this->assign("info",$info); $this->display(); } public function sendMsg(){ $msg = new HomeModelMsgModel(); if (!empty($_POST)){ $data = $msg->create(); if($data){ $data["user_hobby"] = implode(",",$data["user_hobby"]); $z = $msg->add($data); if ($z){ $this->redirect("Msg/sendMsg"); } }else{ $this->assign("errorInfo",$msg->getError()); } } $this->display(); } public function upd($id){ $msg = D("Msg"); if (!empty($_POST)){ $z = $msg->save($_POST); if ($z){ $this->redirect("index",array(),2,"修改成功"); }else{ $this->redirect("upd",array("id"=>$id),2,"修改失败"); } }else{ $info = $msg->find($id); $this->assign("info",$info); $this->display(); } } public function addMsg(){ $msg = D("Msg"); if (!empty($_POST)){ $z = $msg->add($_POST); if ($z){ $this->redirect("index",array(),2,"添加成功"); }else{ $this->redirect("addMsg",array(),2,"添加失败"); } }else{ $this->display(); } } public function del($id){ if(D("Msg")->delete($id)){ $this->success("成功",U("index"),2); }else{ $this->error("失败",U("index"),2); } }}模板 文件名 MsgModel.class.php
<?phpnamespace HomeModel;use ThinkModel;class MsgModel extends Model{ //是否批量验证 protected $patchValidate = true; protected $_validate = array( array("title","require","标题不能为空！"), //默认情况下用正则进行验证 array("user","require","留言人不能为空！"), array("msg","require","内容不能为空！"), ); protected $_auto = array ( array("status","1"), // 新增的时候把status字段设置为1 array("id","NULL"), array("admin_user","ms"), array("replay","NULL"), array("update_time","time",3,"function"), // 对update_time字段在更新的时候写入当前时间戳 array("send_msg_time","time",3,"function"), );}视图 文件名 addMsg.html
