The following is an example code for thinkphp to use model general data editing to add and delete. The content is quite good, so I will share it with you now and give it as a reference.

Data Add Function Example

//数据添加
  public function newData($strName="")
  {

    if (IS_POST) {
      //如果用户提交数据
      $model = D("$strName");
      if (!$model->create()){
        // 如果创建失败 表示验证没有通过 输出错误提示信息
        $info = array(
          "info"=>"{$model->getError()}",
          "status"=>"n",
        );
        $this->ajaxReturn($info,'json');
        exit();
      } else {
        if ($model->add()){
          $info = array(
            "info"=>"恭喜操作成功！",
            "status"=>"y",
          );
          $this->ajaxReturn($info,'json');
        } else {
          $info = array(
            "info"=>"操作失败！",
            "status"=>"n",
          );
          $this->ajaxReturn($info,'json');
        }
      }
    }
  }

Data Update Function Example

//数据更新
  public function update($strName="")
  {

    if (IS_POST) {
      //如果用户提交数据
      $model = D("$strName");
      if (!$model->create()){
        // 如果创建失败 表示验证没有通过 输出错误提示信息
        $info = array(
          "info"=>"{$model->getError()}",
          "status"=>"n",
        );
        $this->ajaxReturn($info,'json');
        exit();
      } else {
        if ($model->save()){
          $info = array(
            "info"=>"恭喜操作成功！",
            "status"=>"y",
          );
          $this->ajaxReturn($info,'json');
        } else {
          $info = array(
            "info"=>"操作失败！",
            "status"=>"n",
          );
          $this->ajaxReturn($info,'json');
        }
      }
    }
  }

Data deletion function example

//数据删除
  public function delete($strNmae = '')
  {

    if(IS_POST)
    {
      $id = I('post.id');
      if(!empty($id))
      {
        //用户提交数据删除当前id
        $model = D("$strName");
        $result = $model->delete("$id");

        if($result !== false){
          $info = array(
            "info"=>"操作成功！",
            "status"=>"y",
          );
          $this->ajaxReturn($info,'json');
        }else{
          $info = array(
            "info"=>"操作失败！",
            "status"=>"n",
          );
          $this->ajaxReturn($info,'json');
        }
      }

    }
