how to upload path in codeigniter - php

Question

I am new to CI. Currently I have the following:
$config['upload_path'] = './uploads/';
I just want to know how to update path in codeignitor. I have tried the below code. Is there something I'm doing wrong?
<?php
defined('BASEPATH')`enter code here` OR exit('No direct script access allowed');
class Upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
function index()
{
$this->load->view('upload_form', array('error' => ' ' ));
}
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('Upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
}
?>

Answer 1

From Your code Your file will be uploaded at uploads folder which is in your root directory. $config['upload_path'] = './uploads/'; this is the place where your uploaded files are stored.
You make an directory uploads there where an application folder is .
If you want your current code.
You'll need a destination folder for your uploaded images. Create a folder at the root of your CodeIgniter installation called uploads and set its file permissions to 777.
By default the upload routine expects the file to come from a form field called userfile.
from file uploading class

Use this library to upload... Its easy to use
http://demo.codesamplez.com/codeigniter/file-upload-demo
View
<form action="" method="POST" enctype="multipart/form-data" >
Select File To Upload:<br />
<input type="file" name="userfile" multiple="multiple" />
<input type="submit" name="submit" value="Upload" class="btn btn-success" />
</form>
{if isset($uploaded_file)}
{foreach from=$uploaded_file key=name item=value}
{$name} : {$value}
<br />
{/foreach}
{/if}
Controller
/**
* the demo for file upload tutorial on codesamplez.com
* #return view
*/
public function file_upload_demo()
{
try
{
if($this->input->post("submit")){
$this->load->library("app/uploader");
$this->uploader->do_upload();
}
return $this->view();
}
catch(Exception $err)
{
log_message("error",$err->getMessage());
return show_error($err->getMessage());
}
}

}
public function do_upload(){
$this->remove_dir($this->config["upload_path"], false);
$this->ci->load->library('upload', $this->config);
if($this->ci->upload->do_upload())

$this->ci->data['status']->success = TRUE;
$this->ci->data["uploaded_file"] = $this->ci->upload->data();
}
else
{
$this->ci->data['status']->message = $this->ci->upload->display_errors();
$this->ci->data['status']->success = FALSE;
}
}
function remove_dir($dir, $DeleteMe) {
if(!$dh = #opendir($dir)) return;
while (false !== ($obj = readdir($dh))) {
