Question

I created exact same copy as CI User Guide, I even changed
$this->upload->do_upload("name_of_file_input");
I tried both

./data/
./application/data/

as my folder to upload, CHMOD 0777, and still upload does not work.
I started FF and FireBug to see what headers I am sending/getting from my localhost and I figured that problem could be in .htaccess file but no so sure…

I work on subfolder localhost/something/ (or http://192.168.0.101/sms/)
my routes.php should be fine well no 404s or any other problems besides upload script

Also weird thing is I have to make form like this

<?=form_open_multipart("/sms/upload/do_upload")?>

which creates this

<form action="http://localhost/sms/sms/upload/do_upload" method="post" accept-charset="utf-8" enctype="multipart/form-data">

note double sms/sms/ which is obviously wrong, but my htaccess it redirects correctly as you can see here

HTTP/1.1 301 Moved Permanently
Date: Tue, 28 Aug 2012 01:49:47 GMT
Server: Apache/2.4.2 (Win32) OpenSSL/1.0.1c PHP/5.4.4
Location: http://192.168.0.101/sms/upload
Content-Length: 337
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: text/html; charset=iso-8859-1

if I create form like this

<?=form_open_multipart("/upload/do_upload")?>

it throws me a error well of course it does

HTTP/1.1 301 Moved Permanently

Server: Apache/2.4.2 (Win32) OpenSSL/1.0.1c PHP/5.4.4
Location: http://192.168.0.101/upload/do_upload

and obviously http://192.168.0.101/upload does not exist on my localhost my whole installation is under subfolder /sms/

my .htaccess

<IfModule mod_rewrite.c>
# mod_rewrite rules
RewriteEngine on

 RewriteBase /sms/

# This will make the site only accessible without the "www."

NEW info:

it seems that after hitting “upload” button it is redirected “somewhere” (with data “attached”), and from “somewhere” it is redirected to my actual upload script that does all the work (without data “attached”) therefore I think it is problem of .htaccess.
CI throws this error

You did not select a file to upload.

<?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' => ' ' ));
}

function do_upload()
{
    $config['upload_path'] = './data/';
    //$config['allowed_types'] = 'gif|jpg|png';
    //$config['max_size']   = '100';
    //$config['max_width']  = '1024';
    //$config['max_height']  = '768';
    //$config['file_name'] = $_FILES['userfile']['name'];
    $this->load->library('upload', $config);

    if ( ! $this->upload->do_upload("userfile"))
    {
        $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);
    }
   }
  }
 ?>

it is copy of CI guide I linked above

Answer 1

finally 🙂
the problem was in relative / absolute paths or actually my CodeIgniter settings, there is this line in my config.php

$config['base_url'] = 'http://localhost/sms/';

which is all good, but in my .htaccess file there is no localhost mentioned (there is IP).

The whole problem is solved by putting same “path” in both config files and .htaccess file
