Mod rewrite directory to .html help

Hi

I have set up a Wordpress blog where I have posts like:

mysite.com/directory/thepost/ and now want this to read
mysite.com/directory/thepost.html

How can I achieve this with my .htaccess file ?

the /directory/ is the cat name so there are many of these so this needs to be a wildcard

Additionally, wordpress has set up all the /directory/ as /category/directory/ so I'd like to redirect /category/directory/ to just /directory/

Does that make sense ?

thanks in advance for any help

 

It's not in the .htaccess rather in the permalinks section under Options. Where it says choose permalinks format click on the custom field and put in /%category%/%postname%.html

 

sure - I can change that in WP - but then all inbound links will produce a 404 so I need to mod rewrite as well

 

Use this ? :

Hi - that would seem to be the solution...

but I followed everything and still got a 404 on my old structure (although the new one worked)

I have a writeable .htaccess

So I guess I still need the mod rules

Anyone ?

 

Last try
RewriteRule ^([-_a-zA-Z0-9]+)/([-_a-zA-Z0-9]+)/$ /$1/$2.html [R=301,L]
