tp框架做留言板
首先是登录的LoginController.class.php
代码内容是
<?php namespace Admin\Controller; use Think\Controller; class LoginController extends Controller { public function dengLu() { if(empty($_POST)){ //判断是不是空 $this->show(); } else{ $a=D("yonghu"); //读取用户表 $b=$_POST; $url=U('LiuYan/zhuYeMian'); //用u方法获取路径 $m=$a->find($b[uid]); //通过提交的密码找表里面的密码 session("uid",$m[uid]); //吧id存进session if($b[pwd]==$m[pwd]&&$m[pwd]!=""){ $this->success("登陆成功",$url); }else{ $this->error("登陆失败"); } } } }
登录页面在View下面叫login文件夹下面的dengLu.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题文档</title> </head> <style type="text/css"> *{ font-family:微软雅黑; padding:0px; margin:0px auto} </style> <body> <form action="__ACTION__" method="post"> <div style=" width:370px; height:210px; background-color: #CCC; text-align:center"> <div style="position:relative; top:30px"><h1>开发部内部留言板</h1></div> <br /> <div style="position:relative; top:30px; height:40px;">用户名:<input id="yonghuming" type="text" name="uid" /></div> <div style="position:relative; top:30px; left:9px; height:40px;">密码:<input id="mima" type="text" name="pwd" / ></div> <div style="position:relative; top:30px; height:40px;"> <input type="submit" value="登录" /> <input type="button" value="复位" onclick="Fuwei()"/></div> </form> </div> <script type="text/javascript"> function Fuwei() { document.getElementById("yonghuming").value = ""; document.getElementById("mima").value = ""; } </script> </body> </html>
然后做一个父级的方法来验证是不是登录了在Controller文件夹下面建立个FuController.class.php
<?php namespace Admin\Controller; use Think\Controller; class FuController extends Controller//造一个FuController类，用来判断session值是否存在。 { public function __construct()//造一个构造函数 { parent::__construct(); if(session('?uid'))//判断session是否存在，如果存在，什么也不做。 { } else//如果不存在 { //$url = U("Home/Login/login"); $this->redirect("Admin/Login/dengLu",array(),1,'请登录');//第一个参数是跳转的地址，第二个参数是要传的值，第三个参数是跳转的时间，第四个参数是跳转时的提示信息。 exit; } } }
做liuYanController.class.php
<?php namespace Admin\Controller; use Admin\Controller\FuController; class LiuYanController extends FuController //将Controller换成FuController { public function zhuYeMian(){ $aa = D("liuyan"); $cc =session("uid"); $nn=$aa->where("fasongren = '$cc' or jieshouren = '$cc' ")->select(); $this->assign("dd",$nn); $this->show(); } public function faSong(){ if(empty($_POST)) { $this->show(); } else { $nnn = D("liuyan"); $ccc =session("uid"); $bbb=$_POST; if(!empty($bbb[jieshouren])&&!empty($bbb[xinxineirong])){ $data[time]=date("Y-m-d H:i:s"); $data[jieshouren]=$bbb[jieshouren]; $data[xinxineirong]=$bbb[xinxineirong]; $data[fasongren]=$ccc; $ff=$nnn->add($data); if($ff) { $this->success("发送成功","faSong"); } else { $this->error("发送失败"); } } else{ $this->error("不能为空","faSong"); } } } public function tuiChu(){ $aaa = session("uid",null); if(!session("?uid")){ $this->success("退出成功","login/denglu");; } } }
然后就是liuyan文件夹下面的主页面和发送页面zhuYeMian.html和faSong.html
