Localization in Routes

Hi, thanks for your comments !

I think you both have valuable arguments, storing the language in a cookie is indeed a valid solution to this problem, however it is not our preferred approach.

To answer my own question, I found that I could implement the desired functionality through the creation of a Filter (see code below)

application\Filters\Localization.php :

PHP Code:

<?php namespace App\Filters;

use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use CodeIgniter\Filters\FilterInterface;

class Localization implements FilterInterface
{
    public function before(RequestInterface $request)
    {
        $supportedLocales = $request->config->supportedLocales;

        if(sizeof($supportedLocales) > 1){
        
        // more than one locale...
        $seqments = $request->uri->getSegments();

        if($request->uri->getTotalSegments() > 0 && !in_array($request->uri->getSegment(1), $supportedLocales)){

        // TODO: check for exceptions (non-localized routes)

        return redirect($request->config->defaultLocale);
        }

        }

    }

    //--------------------------------------------------------------------

    public function after(RequestInterface $request, ResponseInterface $response)
    {
        // Do something here
        // var_dump($response);
    }
} 


application\Config\Filters.php:

PHP Code:

<?php namespace Config;

use CodeIgniter\Config\BaseConfig;

class Filters extends BaseConfig
{
    // Makes reading things below nicer,
    // and simpler to change out script that's used.
    public $aliases = [
        'localization'    => \App\Filters\Localization::class,
        'csrf'            => \App\Filters\CSRF::class,
        'toolbar'        => \App\Filters\DebugToolbar::class,
        'honeypot'        => \App\Filters\Honeypot::class
    ];

    // Always applied before every request
    public $globals = [
        'before' => [
            'localization'
            //'honeypot'
            // 'csrf',
        ],
        'after'  => [
            'toolbar',
            //'honeypot'
        ]
    ];

    // Works on all of a particular HTTP method
    // (GET, POST, etc) as BEFORE filters only
    //     like: 'post' => ['CSRF', 'throttle'],
    public $methods = [];

    // List filter aliases and any before/after uri patterns
    // that they should run on, like:
    //    'isLoggedIn' => ['before' => ['account/*', 'profiles/*']],
    public $filters = [];
}
