Hi all, I am migrating some forums from vbulletin 3.8.x to xenforo, and trying to keep my old link structure alive. Basically, XF provides some php files that I can redirect the old url style to and it handles the proper 301 redirection.

Regardless of that end, I am having difficulty rewriting the rules which I can only find defined in apache's rewrite style:

RewriteRule [\d]+-[^/]+/.+-([\d]+)/([\d]+)/ showthread.php?t=$1&page=$2 [NC,L]
RewriteRule [\d]+-[^/]+/.+-([\d]+)/ showthread.php?t=$1 [NC,L]
RewriteRule ([\d]+)-[^/]+/([\d]+)/ forumdisplay.php?f=$1&page=$2 [NC,L]
RewriteRule ([\d]+)-[^/]+/ forumdisplay.php?f=$1 [NC,L]

I have been experimenting and thought this should work, but obviously not:

 if (!-e $request_filename) {
     rewrite [0-9a-zA-Z\-]/[0-9a-zA-Z\-]-([0-9])/([0-9])/ /showthread.php?t=$1&page=$2 last;
     rewrite [0-9a-zA-Z\-]/[0-9a-zA-Z\-]-([0-9])/ /showthread.php?t=$1 last;
     rewrite ([0-9])-[0-9a-zA-Z\-]/([0-9])/ /forumdisplay.php?f=$1&page=$2 last;
     rewrite ([0-9])-[0-9a-zA-Z\-]/ /forumdisplay.php?f=$1 last;
     rewrite ^(.*)$ /index.php last;
}
