);
// Only updates password if post value true
if(isset($_POST['password'])) {
$data = array(
'password' => $this->input->post('password');

上传控制器
<?php
class Upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
function index()
{
$this->load->view('upload_form', array('error' => ' ' ));

$config['max_size'] = '0'; // Unlimited
$config['max_width'] = '0'; // Unlimited
$config['max_height'] = '0'; // Unlimited
$this->load->library('upload', $config);
// Alternately you can set preferences by calling the initialize function. Useful if you auto-load the class:
$this->upload->initialize($config);
$input_name = "userfile";
if ( ! $this->upload->do_upload($input_name))
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else

$this->db->where('id', $user_info['id']);
$this->db->update('tablename', $data);
}
$this->load->view('upload_success', $data);

}
public function get_user() {
// your user model data
