BUG in csv file uploading

[eluser]colinbird[/eluser]
I ended up making a sub-class of upload that overrode the is_allowed_filetype() method

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

require_once("Upload.php");

class Csvupload extends CI_Upload{

function Csvupload($props = array())
{
parent::CI_Upload($props);
}

function is_allowed_filetype()
{
$data = $this->data();
return $data["file_ext"] == ".csv";
}
}
