php实战第六天

今天学习了做后台页面，很失败就不展示了。

php方面：以下代码可以屏蔽php注意级别的错误，即抛出任何非注意错误

[php] error_reporting(E_ALL&~E_NOTICE);

error_reporting(E_ALL&~E_NOTICE);
开启session的方法，开启后就可以使用$_SESION咯。

session是保存在服务端的东西噢。启动后会给浏览器发送一个 session的ID，是cookies方式的

[php] session_start();

session_start();
如果浏览器禁用了cookies那也不要紧，可以把session写到URL里就好咯.嘿嘿

[php] session_name.'='.session_id()

session_name.'='.session_id() 附上我写好的 adminAction，只有登陆功能哦

[php] <?php
    /**
     *
     **/
    class adminAction extends Action
    {
        protected $db='';
        function __construct()
        {
            // code...
            // //$smarty->force_compile = true;
            /*$this->db = new MySQL("127.0.0.1","root","1234","myly","data");
            $this->db->table('data');*/
            $this->db = MySQL::getClass();
            //var_dump($this->db);
            $this->db -> connect("127.0.0.1","root","1234","myly");

            $this->db -> table('user');

            parent::__construct();
        }

        public function index()
        {
            if($this->is_login()){
                echo "<script>window.location.href='admin.php?m=admin&a=admin';</script>";
            }else{
                echo "<script>window.location.href='admin.php?m=admin&a=login';</script>";
            }
        }

        private function is_login()
        {
            return $_SESSION['login'];

        }

        public function login()
        {
            if (!empty($_POST['userName']) && !empty($_POST['password'])) {
                $userName=$_POST['userName'];
                $password=md5($_POST['password']);
                /*var_dumP($_POST);
                var_dump($password);
                var_dump($password);*/
                if($_SESSION['userData']=$this->db->where("userName='{$userName}' and password='{$password}'")->fine()){
                    echo "<script>window.location.href='admin.php?m=admin&a=admin';</script>";
                    $_SESSION['login']=true;

                }else{

                    echo "登录失败";
                }
            }

            $this->display();
        }

        public function ulogin()
        {
            echo "<script>window.location.href='admin.php?m=admin&a=login';</script>";
            unset($_SESSION);
        }

        public function admin()
        {
            if(!$this->is_login()){
                echo "<script>window.location.href='admin.php?m=admin&a=login';</script>";
            }
            //var_dump($_SESSION);
            $this->assign('userName',$_SESSION['userData']['userName']);
            $this->display();
        }

        function add(){
            /*var_dump($this->db
                ->data(
                    array('userName' => 'admin',
            &nb
