How to run Two Wordpress blogs with different themes and with single database and same content

Question

How do you run two Wordpress blogs with different themes using one database where the content remains the same in both sites? The issue that I am getting is at the Domain mapping in both blogs.

Answer 1

I'll try to explain how it might be done, but not sure it will work:

1. Install 2nd website with single db (2 copies).

2. Create new table in your db. Call it wp_options2 and copy everything from wp_options into the new table

3. in second install in wp-config.php, before if ( !defined('ABSPATH') ) add

   define( 'M7_OPTIONS_TABLE', 'wp_options2' );
   

4. in second install go to wp-includes/wp-db.php on line 1054(for WP 5.6) and add this code:

   if ( isset( $tables['options'] ) && defined( 'M7_OPTIONS_TABLE' ) )
       $tables['options'] = M7_OPTIONS_TABLE;
   

   (This code should be added to the public function tables function, before if ( isset( $tables['users'] ) && defined( 'CUSTOM_USER_TABLE' ) ) )

Now you should be able to change the theme, plugins atc. for the second theme, but all posts, taxonomies etc. will be doubled in both websites (wich is bad for seo btw.)

Should you run into problems with links on your second install, add:

define('WP_HOME','http://seccond_website.com');
define('WP_SITEURL','http://seccond_website.com');

in your wp-config.php file .....

but it wouldn't solve the problem if you were to create some post on the 1-st website, on the second website it would link to the first website...

I'll still post this answer, even though it's not correct (because of the problem described above).

As a solution you could create 2 separate installs with different $table_prefix and add an action to each move (save_post, save_taxonomies, save_postmeta etc.) to save from 1 db to the other, but changing the necessary links.

Or you could create a cron job on the second install to parse every post, page etc from the 1-st db to the 2-nd (since you have the access to both of them, it would be easy)

Answer 2

Not sure if it will be enough but this two plugins should give you most of what you want Any hostname - change the content urls to reflect the domain in which the content was requested Domain Theme - change the them according to the domain name.

I haven't tested any of them but it looks like even if they don't work you can get useful pieces of code from them.

Answer 3

If you have two separate WordPress installations (one per domain), you can define WP_SITEURL and WP_HOME in wp-config.php to force a specific address/hostname. Add this code to each wp-config.php:

define('WP_HOME','http://example.com');
define('WP_SITEURL','http://example.com');

And change example.com to the name of the domain in question.

Answer 4

Let me repeat your question in my words: you want two wordpress sites, using the same database and the same content. Just having a different theme and a different domain name?

That's duplicate content an google will rank both your sites badly for doing so.

I highly encourage you not to do so.

If you just want to share parts. Have a look at the switch_to_blog() function provided by WordPress multisite.

Answer 5

You can change the theme based on the current domain like

function select_theme( $current_theme ) {
    if ( 'domain1.com' === $_SERVER['HTTP_HOST']) {
        return 'domain1 theme name';
    } else {
        return 'domain2 theme name';
    }
}

add_filter( 'stylesheet', 'select_theme' );
add_filter( 'template', 'select_theme' );
