正文tp后台方法简化:

 //用户验证
   function checknm($name){
       $info = D('user')->where("user_name ='$name'")->find();
       //dump($info);die;
       $flag = '';
       if($info){
          echo 1;
         
       }else{
          echo 2;
        
       }
   }

后台返回1和2

前端ajax部分 用data接收1和2的状态

当然data的接收 主要看你后台传的是什么格式的数据类型了!这个大家可以百度ajax了!
