WordPress auto language detection with nginx

My blog uses the “Stella plugin free” wordpress plugin. Unfortunately this plugin doesn’t support auto language detection in the free version. But nginx has a plugin for language detection which can do the job as well. This is my sample configuration which works fine.

server {
    listen 80;
    listen [::]:80;

    server_name hellmi.de www6.hellmi.de www.hellmi.de;

    set_from_accept_language $lang en de;

    location / {
        rewrite ^/(.*) /$lang/$1;
    }

    location = /en {
        rewrite ^ /en/;
    }
    location /en/ {
        rewrite ^/en/(.*) https://www.hellmi.de/en/$1 permanent;
    }

    location = /de {
        rewrite ^ /de/;
    }
    location /de/ {
        rewrite ^/de/(.*) https://www.hellmi.de/$1 permanent;
    }     
}

The nginx module can be found here: nginx_accept_language_module
