//这应该运行并共享您的模型

//同时检查url它似乎不正确它有重复的名称

帮助我们：您看到了什么错误？没有看到错误，但我无法访问表单中的值您使用浏览器的开发人员工具进行调试了吗？请参阅：或者是，没有错误。只需添加html表单代码函数update\u db\u row\u date$inputdata{$this->db->trans\u start；$sql=update tg\u partner\u data SET followup\u date='。$this->db->escape\u str$inputdata['followup\u date'].'WHERE partner\u data\u id='。$this->db->escape\u str$inputdata['hid_check_id'].$this->db->query$sql；$this->db->trans_complete；}
