从上传的 excel 文件中检索值并将其存储到数据库中

Question

我正在尝试将每个员工的考勤详细信息从 excel 文件保存到数据库中作为批量考勤上传，下面的代码显示 Excel 数据导入成功，但不存储值进入数据库，行 $last_id=$this->mod_common->add_attendence_data($data_user);没有执行，这就是为什么它不起作用，如何让这一行执行？由于这段代码是由其他一些开发人员编写的，我发现它很难理解。

控制器：admin_list.php

 function upload_bulk_attendance(){
  $data['htmltext'] = $this->mod_common->get_allleaves();
