problem is that when m getting the results from view it showing me the warning with the result: 
first warning:
A PHP Error was encountered
    Severity: Notice
    Message: Undefined variable: query
    Filename: views/results.php
    Line Number: 16

第二次警告：遇到PHP错误严重性：警告消息：为foreach（）提供的参数无效文件名：views / results.php 行号：16

and page also not redirecting to the next url that is results.php.what is the issue in this code y m getting warning and why page is not redirecting

Answer 1

您已在同一个控制器中加载了两次视图页

$this->load->view('results');

和

 $this->load->view('results',$data);

删除第一个

$这 - ＆GT;负载＆gt;查看（ '结果'，$数据）;

Answer 2

尝试将查询更改为结果!!!

并且还使用error_reporting（0）;（在函数__construct中的控制器中）

foreach（ $ results as $ val）

在codeigniter中使用输出返回警告
