I have made a helper function for me which upload the files and return a array with upload result.It takes a parameter upload directory where to save the files. Here is the my function

function upload_file($save_dir="images")//takes folder name where to save.default images folder
{
    $CI = & get_instance();
    $CI->load->library('upload');
    $config=array();
    $config['upload_path'] = FCPATH.$save_dir;
    $config['allowed_types'] = 'gif|jpg|png';//only images.you can set more
    $config['max_size'] = 1024*10;//10 mb you can increase more.Make sure your php.ini has congifured same or more value like this
    $config['overwrite'] = false;//if file do not replace.create new file
    $config['remove_spaces'] = true;//remove sapces from file
    //you can set more config like height width for images

    $uploaded_files=array();
    foreach ($_FILES as $key => $value)
    {
        if(strlen($value['name'])>0)
        {
            $CI->upload->initialize($config);
            if (!$CI->upload->do_upload($key))
            {
                $uploaded_files[$key]=array("status"=>false,"message"=>$value['name'].': '.$CI->upload->display_errors());
            }
            else
            {
                $uploaded_files[$key]=array("status"=>true,"info"=>$CI->upload->data());
            }

        }

    }
    return $uploaded_files;

}

Sample output
if you print out the function returns you will get the output like this

Array
(
    [file_input_name1] => Array
        (
            [status] => 1//status will be true if uploaded
            [info] => Array //if success it will return the file informattion
            (
                    [file_name] => newfilename.jpg
                    [file_type] => image/jpeg
                    [file_path] => C:/Program Files (x86)/VertrigoServ/www/rnd/images/
                    [full_path] => C:/Program Files (x86)/VertrigoServ/www/rnd/images/newfilename.jpg
                    [raw_name] => newfilename
                    [orig_name] => newfilename.jpg
                    [client_name] => newfilename
                    [file_ext] => .jpg
                    [file_size] => 762.53
                    [is_image] => 1
                    [image_width] => 1024
                    [image_height] => 768
                    [image_type] => jpeg
                    [image_size_str] => width="1024" height="768"
                )

        )


    [file_input_name_2] => Array
    (
         [status] =>//if invalid file status will be false with error message
        [message] => desktop.ini: <p>The filetype you are attempting to upload is not allowed.</p> 
        )

)
