htaccess code to 301 Wordpress subdomain to subfolder

Hi there,

Please could you help me write a piece of code for the .htaccess file of a wordpress site?

We've managed to get the site mirrored from a subdomian to a subfolder for SEO purposes.  I now need to update the htaccess code so that ALL PAGES of the blog are 301'd across to the relevant subfolder pages as in the example below:

Current Structure
homepage: http://blog.domain.com
post example: http://blog.domain.com/post-titles/
page example: http://blog.domain.com/page-titles/

New Structure:
homepage: http://www.domain.com/blog/
post example: http://wwwdomain.com/blog/post-titles/
page example: http://wwwdomain.com/blog/page-titles/

However, the only way to access the Wordpress CMS is still through the sub domain, therefore the path http://blog.domain.com/wp-admin/ would need to be excluded from the redirect.

Here is the only other code in the file:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

Please help. Thank you.

In the htaccess in the subdomain folder use

RewriteEngine on
RewriteCond %{HTTP_HOST} blog.domain.com$
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]

Open in new window

Update the .htaccess in the blog.domain.com with the following code (this includes the WP code already installed):

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteCond %{HTTP_HOST} blog.domain.com [NC]
RewriteCond %{REQUEST_URI} !^/wp-admin/$
RewriteRule ^(.*)$ http://www.domain.com/blog/$1 [R=301,L]

Open in new window

This will provide a 'parallel redirect' which allows the old files and folders, to point to the new files and folders, rather than just redirecting everything to the new root folder and losing potential link juice, while also excluding the wp-admin folder from the redirect process.

Why don't you just change the wordpress site structure?
You can add a plugin called search and replace https://wordpress.org/plugins/search-and-replace/

Check mark all tables
search for: blog.domain.com
replace with: domain.com/blog

Now you would be able to use domain.com/blog/wp-admin to login!
