• tp框架做留言板


    首先是登录的LoginController.class.php

    代码内容是

    <?php
    namespace AdminController;
    use ThinkController;
    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=" 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" />
        &nbsp;    
        <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 AdminController;
    use ThinkController;
    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 AdminController;
    use AdminControllerFuController;
    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

            <td>{$v.xinxineirong}</td>
        </tr>
        
        </foreach>
        
    </table>

    <body>

    </form>
    <a href="__CONTROLLER__/zhuYeMian"><input type="button" value="返回主页" /></a>
    <a href="__CONTROLLER__/tuiChu"><input type="button" value="退出" /></a>
    </body>
    </html>
