The goal is to have this working:

www.pageurl.de -> nothing happens

www.pageurl.de/en/ -> a variable is set and stored in a cookie

this also need to work with permalinks, categories etc. like this:

www.pageurl.de/en/linktopost/

www.pageurl.de/en/categoryname/

i tried to work with
add_rewrite_endpoint('en',EP_PERMALINK|EP_PAGES|EP_ROOT|EP_CATEGORIES);

but the endpoint (that makes sense) only works at the end of the url

i also tried to work with

$language="en"; add_rewrite_rule('^' . $language . '/([^/]*)/?$', 'index.php?lang=$matches[1]', 'top'); but www.pageurl.de/en/ only returns a 404

What is the best way to do this?

I need to have the language pattern in the url on the whole page, lets say after changing the page in a menu the "en" has to be in the url.

You cannot do this by just adding a rewrite rule, you need to change every recorded rules.

Here is a simple way to do this:

function my_rewrite_rules($rules) {

    $new_rules = array();

    $new_rules['(?:de|en)/?$'] = 'index.php';

    foreach ($rules as $key => $val) {

        $key = '(?:de|en)/?' . $key;

        $new_rules[$key] = $val;

    }

    return $new_rules;
}

add_filter('rewrite_rules_array', 'my_rewrite_rules', 11);

Now you still need a way to receipt the language value in order to save it in a cookie.

You could add a parameter for the language, in order to get it inside the $_GET super global. But that would means to offset all other parameters of all other rules, and this would involve a lot of regex.

Instead you can simply get the language by querying the $_SERVER global:

preg_match('/\/(de|en)(\/|$|\?|#)/', $_SERVER['REQUEST_URI'], $matches);

  • thanks alot, that is great, now i set a cookie with the value from the regex. Do you know how it is possible to have the language paramter ("/en/") in the url on the whole page? How to add the parameter to every link an the page? Thank you very much! – buckdanny Sep 6 '16 at 20:24
  • For this you can add a filter to "home_url" (developer.wordpress.org/reference/hooks/home_url) and append the language slug to the returned url. – maxime schoeni Sep 7 '16 at 14:15
  • wow, thanks alot, that is a great hint! one more problem: the rewrite rules are working for the index and for pages but not for custom post type posts, links give a 404, do you know why? – buckdanny Sep 8 '16 at 9:02
  • i think i could fix it by ` $key = '(?:de|en/)?' . $key; ` changing to $key = '(?:de|en)/?' . $key; – buckdanny Sep 8 '16 at 10:28
  • next issue: the home_urlfilter is only modifying permalinks but not echo(home_ur)l or get_bloginfo('url') I dont understand why – buckdanny Sep 8 '16 at 10:49
