nginx rewrites vBulletin to XenForo

There is a similar question here but the answer does not work, and the official answer from XenForo does not work either. Apparently they had an issue with forums moving from a /forums setup to the root domain level, but the fix for that does not work.

This does work on non-friendly URLs, but I do not have many of those.

           return 301 /threads/$arg_t/;
        }

        location = /member.php {
           return 301 /members/$arg_u/;
        }

I think what is throwing me off is the swap between text and id. In vBulletin its id-then-the-text

In XenForo its the-text.id

Solution

  • Of course the $arg_u or $arg_t variables are empty with the request example you've provided. These variables hold the value of the corresponding query argument — for example:

    Instead, you need to work with the $args variable, which contains the full query string. Nginx’s built-in string manipulation capabilities are very limited, but the following approach should work for you:

    map $args $xf_id {
    ~^(\d+)-(.+)$  $2.$1;
}
server {
    ...
    location = /forums/member.php {
        return 301 /members/$xf_id/;
    }
    location = /forums/showthread.php {
        return 301 /threads/$xf_id/;
    }
    ...
}

    Nginx does not provide built-in case conversion functions. However, based on a quick test with your URL sample, this setup should work, though it will result in an additional 301 redirect from:

    https://twcenter.net/members/Gaius-Baltar.10263/

    to:

    https://twcenter.net/members/gaius-baltar.10263/

    Note that the map directive must be declared in the http context, at the same level as the server directive, not inside a server block.
