Use mod_rewrite to remove year and month from wordpress post's url, while keeping year and month permalink structure

I've been around the world and back with this mod_rewrite syntax and I'm having a hard time constructing some working rewrite rules.

Scenario:

Working in Wordpress, I want to remove "year/month" from the url structure while keeping the year/month custom permalink activated. Reason being I'm using a plugin that generates a category specific archive, but the plugin is dependent on the permalink structure being:

/%cateogry%/%year%/%monthnum%/%postname%

Goal:

I want to change this path: category/2010/12/post-name

to this path: category/post-name

Condition:

If the year/month is present in the url and it is followed by a forward slash (/) with characters after the slash (eg. category/2010/12/post-name) {

Remove the year/month from the url;

// intended output: category/post-name

// in this case I am directly clicking on a link.

} else {

//leave it alone; 
//intended output: category/2010/12/


/*=======
In this case I am already in the archive section and will want the 
plugin to display the archive according to the year & category

=======*/

}

I have this rule written in the .htaccess file

RewriteRule ^category/[0-9]{4}/[0-9]{2开发者_Python百科}/$         news/$1 [L, NC]

Can anyone help please (if you can, explain some of the things you are doing so I can familiarize myself more with it)?

Your question is a little confusing, but let me see if I understand.

You want to change:

http://somehost.com/category/2011/11/some-post

to:

<webroot>/category/some-post

If that's the case, you're almost there. In the rewrite you have a backreference ($1), but that backreference isn't defined anywhere in the search pattern. In order to define a backreference, you surround the portion with parenthesis. Updating your rule would look like this (also taking into account a variable category):

RewriteRule ^(.*)/[0-9]{4}/[0-9]{2}/(.*)$ $1/$2 [L,NC]

goto Admin - Settings - Permalinks

Select custom structure and use

/%postname%/
