error in uploading the image to the upload folder - php

Question

I've been trying to get this to work since this morning, but have no idea why it doesn't. The uploaded image gets stored in the database, but when I check my upload folder --where I want to store the images -- there's nothing there.
Can anyone help me with this problem?
Home.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Home extends CI_Controller {
public function __construct()
{
parent::__construct();
//load database libray manually
$this->load->database();
//load Model
$this->load->model('Contact_model');
// load form and url helpers
$this->load->helper(array('form', 'url'));
// load form_validation library
$this->load->library('form_validation');
}
public function Latest_news()
{
$this->form_validation->set_rules('first_content', 'First content', 'required');
$this->form_validation->set_rules('second_content', 'Second content', 'required');
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload', $config);
if (($this->form_validation->run() == FALSE )&&(!$this->upload->do_upload('filename')))
{
$this->load->view('Latest_news');

else

Answer 1

Use function form_open_multipart() in Latest_news.php instead form_open()
