Question

I’m using this URI Language Identifier

http://localhost/internationalisation/index.php/en/
http://localhost/internationalisation/index.php/en/welcome/
http://localhost/internationalisation/index.php/en/contact/
http://localhost/internationalisation/index.php/es/
http://localhost/internationalisation/index.php/es/welcome/

I’ve set $config['lang_ignore'] = FALSE; so the URL shows what language I’m currently using like above.

Question: How can enable users switching between languages?

These codes in View won’t work:

<a href="<?php echo site_url('en'); ?>">English</a>
<a href="<?php echo site_url('es'); ?>">Spanish</a>

because they produce links like this:

http://localhost/internationalisation/index.php/en/en
http://localhost/internationalisation/index.php/en/es

Thanks

Followed LastCoder’s first suggestion:

CONFIG:

$config['lang_ignore'] = FALSE;

VIEW:

<a href="<?php echo site_url('language/en'); ?>">English</a>
<a href="<?php echo site_url('language/es'); ?>">Spanish</a>

CONTROLLER:

class Language extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();

        $this->load->helper('url');

        $lang_uri_abbr = $this->config->item('lang_uri_abbr');

        if ($this->uri->segment(2) === false ||
            ! isset($lang_uri_abbr[$this->uri->segment(2)]))
        {
            redirect();
        }
        else
        {
            $site_url = substr(site_url(), 0, -2);

            redirect($site_url . $this->uri->segment(2));
        }
    }
}
