    增加数据

     
    <?php
    namespace HomeController;
    use ThinkController;
    class IndexController extends Controller {
         
        public function add(){
            $db = D("Info");
            //1.使用数组方式
            $arr =
            array("Code"=>"p005","Name"=>"aaa"
            ,"Sex"=>1,"Nation"=>"n003","Birthday"=>"1999-02-03");
            $db->add($arr);
            //2.使用映射的方式
            $db->Code = "P006";
            $db->Name = "hgjgf";
            $db->Sex = 1;
            $db->Nation = "C004";
            $db->Birthday = "1996-03-04";
            $db->add();
        }
    }

    自动收集表单的方法

    首先在index文件夹中新建一个add文件
