tp5框架增删改查，相对于以前的源生代码而言，非常简单，主要是为了熟练的应用框架，下面的代码主要是tp5框架的增删改查，让我们的更好 掌握框架。
<?php namespace app\index\controller; use think\Controller; use think\Db; use think\Request; class Index extends Controller { public function index(){ return view("index"); } //添加 public function add(){ $data = Request::instance()->param(); $res = Db::table('yun')->insert($data); if($res){ return $this->success("添加成功","show"); }else{ return $this->success("添加失败","index"); } } //展示 public function show(){ $data = Db::table("yun")->order('id asc')->select(); return view("show",['data'=>$data]); } //删除 public function del(){ $id=Request::instance()->param("id"); $res=Db::table("yun")->where('id',$id)->delete(); if($res){ return $this->success("删除成功","show"); }else{ return $this->success("删除失败","show"); } } //查询单条数据 public function update(){ $id=Request::instance()->param("id"); $data = Db::table("yun")->where('id',$id)->find(); return view("update",['data'=>$data]); } //修改 public function updates(){ $id=Request::instance()->param("id"); $data=Request::instance()->param(); $res=Db::table("yun")->where('id',$id)->update($data); if($res){ return $this->success("修改成功","show"); }else{ return $this->success("修改失败","show"); } } }
