Nginx Config Location Regex With Language Code In Url

nginxregexregular expressionsrewriteurl

Trying to achieve constant language code in url's 1st segment with nginx regex location configuration and could not find the correct syntax.

Necessary result:

  • example.com stays example.com
  • example.com/en stays example.com/en
  • example.com/en/ stays example.com/en or example.com/en/ (don't care)
  • example.com/en/etc stays example.com/en/etc

  • example.com/etc changes to example.com/en/etc
  • example.com/etc/segment changes to example.com/en/etc/segment

Currently I have found out this code but it still stuck in somewhere. It makes permanent loop and doesn't not use $1 argument.

location ~ "^/(?![a-z]{2}/)(.+)$" {
    rewrite / /en/$1 permanent;
}

#Using handler here for removing index.php in uri (example.com/index.php -> example.com);
location / {
    index index.htm index.html index.php;
    try_files $uri $uri/ @handler;
}

location @handler {
    rewrite / /index.php?$query_string;
}

The @handler location will rewrite the URI to /index.php which is then redirected to /en/index.php, which (if it doesn't exist) invokes the @handler location.

Read this document because you need something to handle PHP. The redirect loop is caused because the file or handler does not exist. You need to define a location to handle PHP files, either another regex location or your named location.
