Question

I have conroller baner, and when I try to run it (run upload function http://localhost/010/baner/upload_img), I got 404 error:

The page you requested was not found

What is wrong here?

The controller:

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

class Upload_Baner extends CI_Controller {

    protected $path_img_upload_folder;
    protected $path_img_thumb_upload_folder;

Your controller is named Upload_Baner so unless you have a route defined that maps baner to upload_Baner this won’t work. Does this url work?:

http://localhost/010/upload_Baner/upload_img

That is what your current controller will map to without the route.
