PHP：
<?php
namespace app\index\controller;
use think\Controller;
use think\View;
use think\Request;
use think\Db;
class Index extends Controller
{
public function useradd(Request $request){
//判断是否有post提交request()->isPost()
if(request()->isPost()){
$data = $request->post();
var_dump($data);
$res = Db::table("users")->insert($data);
if($res){
return "666";
}else{
$this->success("NO","useradd");
}
}else{
//没有post提交，调取添加页面
return view();
}
}
}
如果是多条数据入库可用insertAll（）方法，insertAll 方法添加数据成功返回添加成功的条数
