2 sites same theme same db different languages

I think I found a way to do this in a post 7 years old

I’ve done this before, having 6 websites shoot out content from the same database.

It’s easy enough to do. Upload WP into both directories. Make sure they have the identical wp-config.php file.

In the second sites directory do the following:
In the wp-settings.php file change the options database value to something like this:

// Table names
$wpdb->posts = $table_prefix . ‘posts’;
$wpdb->users = $table_prefix . ‘users’;
$wpdb->categories = $table_prefix . ‘categories’;
$wpdb->post2cat = $table_prefix . ‘post2cat’;
$wpdb->comments = $table_prefix . ‘comments’;
$wpdb->links = $table_prefix . ‘links’;
$wpdb->linkcategories = $table_prefix . ‘linkcategories’;
$wpdb->options = ‘YOURNEWPREFIX_options’;
$wpdb->postmeta = $table_prefix . ‘postmeta’;
$wpdb->usermeta = $table_prefix . ‘usermeta’;

$wpdb->prefix = $table_prefix;

See how I’ve removed $table_prefix . in the options line?
Instead of YOURNEWPREFIX put something like ‘site2’ or whatever you want.

Then, in PHPmyAdmin duplicate the wp_options table, and rename one of the them to be YOURNEWPREFIX_options, so if you chose ‘site2’, it would be ‘site2_options’.

Bingo. Edit the information in the ‘site2_options’ table to refelct the correct information for your second site and you will be on your way.

but can anyone Tell me if this will work with the latest versions of WP.
My client wants his site (Estate agency) to display the same info photos sizes etc with descriptions in two languages

I am really stuck. Your help greatly apprciated
