routing

as like @skunkbad  said you need to call it by href you cannot type in url,

let me teach you ya

here is router.php

Code:

$route['default_controller'] = 'welcome';
$route['add'] = 'welcome/table';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

here is controller

Code:

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

class Welcome extends CI_Controller {


public function index()
   {
       $this->load->view('welcome_message');
   }
   public function table()
   {
       $this->load->view('table');        
   }
}

view calling from welcome

Code:

<h1> Here is view from welcome </h1>
<a href="<?php echo site_url('add') ?>">Click here to see router</a>

view calling by function table

Code:

<h1> Here is view from table function </h1>
