Redirect to the same page after switching the language in Codeigniter

Question

I have language switcher on my website, it works fine. However, it redirects to base URL.

But when I write redirect($_SERVER["HTTP_REFERER"]); it doesn't redirect correctly. When I change the new language on the home page, I should stay at the same URL and just make the website change the language.

How do I solve this problem?

Here is my controller:

<?php 
defined('BASEPATH') OR exit('No direct script access allowed');
class LanguageSwitcher extends CI_Controller
{
    public function __construct() {
        parent::__construct();  
        $this->load->helper('url');    
    }

    function switchLang($language = "") {

        $language = ($language != "") ? $language : "azerbaijani";
        $this->session->set_userdata('site_lang', $language);

        redirect(base_url());

    }
}

Also, I have tried this, it did not work for me:

function switchLang($language = "") {

        if($this->uri->uri_string() == '') {

            $language = ($language != "") ? $language : "azerbaijani";
            $this->session->set_userdata('site_lang', $language);

            redirect(base_url());
        } else {

            $language = ($language != "") ? $language : "azerbaijani";
            $this->session->set_userdata('site_lang', $language);

            redirect($_SERVER["HTTP_REFERER"]);
        }


    }

Try this

$url = $_SERVER['HTTP_REFERER'];
redirect($url);

Try using :

redirect($uri, 'refresh');

where $uri is the url of the home page that you want to translate

Should I define URI before? – Javid Abbasov Nov 30 '17 at 12:28

Hope this might help you

$this->load->library('user_agent');
if ($this->agent->is_referral())
{
    echo $this->agent->referrer();
}

 /*
    |--------------------------------------------------------------------------
    | Base Site URL
    |--------------------------------------------------------------------------
    |
    | URL to your CodeIgniter root. Typically this will be your base URL,
    | WITH a trailing slash:
    |
    |   http://example.com/
    |
    | WARNING: You MUST set this value!
    |
    | If it is not set, then CodeIgniter will try guess the protocol and path
    | your installation, but due to security concerns the hostname will be set
    | to $_SERVER['SERVER_ADDR'] if available, or localhost otherwise.
    | The auto-detection mechanism exists only for convenience during
    | development and MUST NOT be used in production!
    |
    | If you need to allow multiple domains, remember that this file is still
    | a PHP script and you can easily do that on your own.
    |
    */
    $config['base_url'] = 'your domain';

Try to change the base_url in your config.php inside application/config directory with your URL address complete.

What I do in all my projects (maybe not an easy solution for what you're asking for, but realy useful for this and other scenarios) is to use two helpers, I called them history() and back().

History saves current url in an array in session:

$history[] = current_url();
$ci->session->set_userdata('history', $history);

Back($num) receives a number and redirect to that position. i.e: back(1) is equivalent to "send me to the last visited page".

$history = $this->session->userdata('history');
$cant = count($history);
$back = $cant - $num;
redirect($history[$back]);

Then in the __construct() of "CI_Controller" (or whatever class you extend your controllers) call history() once to log every method.

Also, you can add a third controller, I call it no_history().

no_history() deletes the last saved URL (I use it in methods that I don't want to save, for example, ajax requests). You can also check $this->input->is_ajax_request() but it's just an idea.

That's it, now you have a history of visited URLs. You can change whatever you want, and then back(1). Also useful for redirect your users to whatever they were doing before login.

Oh! Almost forgot: Remember to limit the size of the array and always delete the oldest url before adding new one. Between five and ten will be fine.

You could do this with sessions, but I prefer this approach which makes use of an uri-query: What it does, is adding a ?my-current-url part to the link where you call the new language.

So, in my view, I've a link (button, etc.) which calls the language switcher, adding the current site url as uri-query like this:

<?php 
  // set pathname from where we came from
     $pn=uri_string();  // the uri class is initialized automatically
?>
<a href="/LanguageSwitcher/switchLang/azerbaijani?<?=$pn?>">Azerbaijani</a>

then in your function switchLang() you take care of the redirect:

function switchLang($language = "") {
    // get pathname from where we came from
    $pn= parse_url($_SERVER['REQUEST_URI'], PHP_URL_QUERY);
    $language = ($language != "") ? $language : "azerbaijani";
    $this->session->set_userdata('site_lang', $language);

    // redirect to where we came from
       redirect($pn, 'refresh');    
}

it means at the url every time will be `?az` or `?rus` ? – Javid Abbasov Nov 30 '17 at 18:19
no, only at the link(button) or whatever you use to click on, there the new language shows. This is obviously based on your quote: "I have language switcher on my website, it works fine" ?$pn will give you the pathname where you came from – Vickel Nov 30 '17 at 18:21
First, it redirects to `LanguageSwitcher/switchLang/russian ` page and in a moment redirects to that page where I have changed the language. Is it normal? – Javid Abbasov Nov 30 '17 at 18:36
no, the part calls the controller, where you are redirected to the new language page, it should be the same as in your original approach, but instead of redirect(base_url()); now it redirects to the page you came from, but in the new language... BUT WAIT i've set $config['index_page'] = ''; and removed the index part with .htaccess, that could mess up the whole strategy – Vickel Nov 30 '17 at 18:44
should I remove it also? – Javid Abbasov Nov 30 '17 at 18:50
I would, as it is much nicer looking, also think about using routes, then you can associate an inmyownlanguage-link to your controller/function, you'll find all about routes in the CI manual – Vickel Nov 30 '17 at 18:53
Last question, if I don't change .htaccess and route, will there be any problems in future? – Javid Abbasov Nov 30 '17 at 18:59
it should work well any way. You said earlier: "it redirects to LanguageSwitcher/switchLang/russian page" but there is no page called in that controller, just a redirect, which works well on my sites Anyway, you can debug your php code quite easy with e.g. adding this line `echo $pn;die();` before your `redirect()` and see what is the outcome. Play around to make the link work as you need. hope this helped.... – Vickel Nov 30 '17 at 19:05

First load under constructor method like as:

function __construct()
  {
    parent::__construct();
$this->load->library('user_agent');
}

After inserting or updating data then it will work fine.

redirect($this->agent->referrer());
