Seems like you forgot to load the form helper. Use the application/config/autoload.phpor add the following line into your controller before loading the view:
好像你忘记加载表单助手了。application/config/autoload.php在加载视图之前使用或将以下行添加到您的控制器中：
$this->load->helper('form');

You may also load this helpers on all controllers. Go your config folder and open autoload.php in any editor and then load required helper as following :
您还可以在所有控制器上加载此帮助程序。转到您的配置文件夹并在任何编辑器中打开 autoload.php，然后按如下方式加载所需的帮助程序：
$autoload['helper'] = array('url','form');

Load your CI helper in your controller $this->load->helper('form');
在控制器中加载 CI 助手 $this->load->helper('form');
class Create extends CI_Controller{
function index(){
$this->load->view('create_view');
$this->load->helper('form');
or make auto load helpers on all contollers. Open application/config/autoload.php
或在所有控制器上制作自动加载助手。打开 application/config/autoload.php
$autoload['helpers'] = array('form','myhelper');

You need to load Helper 'Form' before using this function. Add this line:
在使用此功能之前，您需要加载 Helper 'Form'。添加这一行：
$this->load->helper('form');
回答by A.Aleem11
Make sure to have following line above view called in controller:
确保在控制器中调用视图上方的以下行：
$this->load->library('form_validation'); //make sure to have it, before view call
$this->load->view('profile');
