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

<style type="text/css">

</style>
<body>
    <form action="__ACTION__" method="post">
    <div style=" width:370px; height:210px;  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="http://www.mamicode.com/登录" />
    &nbsp;    
    <input type="button" value="http://www.mamicode.com/复位" onclick="Fuwei()"/></div>
    </form>
</div>
<script type="text/javascript">
function Fuwei()
{
    document.getElementById("yonghuming").valuehttp://www.mamicode.com/= "";
    document.getElementById("mima").valuehttp://www.mamicode.com/= "";
}
</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
