6月17 练习ThinkPHP的增删改查

利用ThinkPHP连接数据库的增删改查的例题：用到的数据库表名Info表，Nation表

数据显示页面：MainController.class.php中的ShowInfo方法

//例题        
        //显示所有数据
        public function ShowInfo()
        {
            $model = D("Info");
            $attr = $model->field("Info.Code as InfoCode,Info.Name as InfoName,Info.Sex,Nation.Name as NationName,Info.Birthday ")->join("Nation on Info.Nation=Nation.Code")->select();    
            
            $this->assign("shuju",$attr);
            $this->display();
            //var_dump($attr);
        }
        
        //删除数据的操作方法
        public function ShanChu($code)
        {
            $model = D("Info");
            $z = $model->delete($code);
            if($z)
            {
                $this->success("删除成功",U("ShowInfo"));
            }
            else
            {
                $this->error("删除失败");
            }    
        }
