htaccess重写以支持带有下拉选择器的多语言网站。 如何解决这个问题？

Question

This is my structure:

in my page example.com I have multiple languages. In the index page, I have also a dropdown menu that you can change your language. This dropdown appears in other pages too.

This is my htaccess for the root file

RewriteEngine On
RewriteRule ^(en|pl|cz|hu)?$ index.php?lang=$1 [NC,L]

so, i wrote a code that if the domain is example.com/en it will load the English translations.

My problem is on the other pages I can not change the languages and stay on the same page.

So when i am on www.example.com/en and click on link.php ( example.com/link.php ) I can keep the preffered language this through Session

But when I am on example.com/link.php and change the language, the result is not correct (the result is an output of some PHP code that need fixed and i believe it does not suit here)

What I thought is to include the /en/ (or any other language in the urls, like www.example.com/en/link.php

But this gives me a 404 error. I believe is because of the htaccess file and that I do not have any folder named en etc.

How can I solve this? Is it a htaccess thing?

What I can think as a logic but not know how to implement is like

when the domain contains (en|pl|cz|hu) followed by /*** do it through the ****.php?lang=$1

Answer 1

Try this out :

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(en|pl|cz|hu)/(.*)?$ $2.php?lang=$1 [NC,L]

and you can store you lang variable in session, like following :

// link.php
if (isset($_GET['lang']) {
    $_SESSION['lang'] = $_GET['lang'];
}
$lang = $_SESSION['lang'];

Answer 2

EDITED: **Now htaccess will work only for .php files. **

RewriteEngine On RewriteRule ^(en|pl|cz|hu)/([a-zA-Z0-9-/]+).php$ $2.php?lang=$1 [NC,L] Now your link must be www.domain.com/en/index www.domain.com/en/link www.domain.com/pl/link

If you have questions, please ask.

You don't need to use .htaccess at all for this. You can just have the form $_POST back to the page its on.

if ($_POST['language']) {
    $_SESSION[KEY]['Language'] = $_POST['language'];
}

Then depending on the variable within the session, defines what language to use.
