Solution :
Seems like you forgot to load the form helper. Use the application/config/autoload.php or add the following line into your controller before loading the view:
$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 :
$autoload['helper'] = array('url','form');
Load your CI helper in your controller
$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
$autoload['helpers'] = array('form','myhelper');
You need to load Helper ‘Form’ before using this function.
Add this line:
$this->load->helper('form');
Make sure to have following line above view called in controller:
$this->load->library('form_validation'); //make sure to have it, before view call
$this->load->view('profile');
