Question

Iam developing a site in codeigniter.This is my url http://myserver.net/visio/UBwXo.
Here http://myserver.net/visio/ is my base_url.

After /visio/ here have a variable.When there have any value after /visio/ then i wantto take the corresponding url from database to this value.

That means in my database,

UBwXo => “*any url***“

jshom => “*any url***“

So when getting value after /visio/ i want to take the corresponding url from databse and redirect it in to that url without using htaccess.

I want to done this redirection process in index.php page of root folder.

Is this possible?

The orginal url for http://myserver.net/visio/UBwXo like myserver.net/visio/index.php/admin/index/UBwXo

the default controller is admin

First, create redirect.php file in the controllers folder (application/controllers) and add this code to this file:

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

class Redirect extends CI_Controller
{

    /**
     * Method to redirect from an alias to a full URL
     */
    public function index()
    {

    $alias = $this->uri->segment(1);

    $this->db->select('url');

    $query = $this->db->get_where('links', array('alias' => $alias), 1, 0);

    if ($query->num_rows() > 0)
    {
        foreach ($query->result() as $row)
        {
        $this->load->helper('url');

        redirect($row->url, 'refresh', 301);
        }
    }
    else
    {
        echo "Sorry, alias '$alias' not found";
    }
    }

}

Then create table in your database. Your table must be like this:

CREATE TABLE IF NOT EXISTS `links` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `alias` varchar(6) CHARACTER SET utf8 DEFAULT NULL,
  `url` text CHARACTER SET utf8,
  PRIMARY KEY (`id`),
  UNIQUE KEY `alias` (`alias`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=11 ;

After that, set default controller value to the redirect class.
Open application/config/routes.php. Find $route['default_controller'] , then set redirect as a value to this variable, like this:

$route['default_controller'] = "redirect";

Then enjoy life 😉

EDIT:

I had forgotten to mention URI routing in config/routes.php for redirecting:

$route[':any'] = "redirect/index/$1";
