我认为您的form\u open（）方法存在问题

你忘了装东西了

$this->load->helper('form');

尝试阅读手册，了解解决方案：
user_model.php

这个

改为
$query=$this->db->select（'user\u id，email'，'password'）

天哪
 如果你
var\u dump（$result）
，你会得到什么？当我做var\u dump（$result）
array（size=1）0=>object（stdClass）[23]public'user\u id'=>string'19'（length=2）
看起来没有电子邮件我不知道第50行是什么`我已经在autoload中加载了表单：
$autoload['helper']=array（'form'，'url'，'security'）
从check_数据库（$password）中删除$password变量，然后选中并添加$password=$this->input->post（'password'）；在check_database（）函数中仍然存在相同的问题
$this->load->helper('form');

$query = $this->db->select('user_id','email','password')
