I want to be able to customize my theme from any of my sites (mainsite or any subsite) and have that change impact on the entire network.

Right now when I customize, i.e., my main site it doesn't replicate the changes to the rest of subsites.

I know this data is stored under theme_mods_themename, but I need to "copy and paste" this new values (New values generated when I use the customizer) on every site.

Is there a way to "unify" this setting?

Thank you in advance.

UPDATE (DECEMBER 21 2021):

I've found another thing that was making me lose my mind. At least in my case, theme colors are not stored with the rest of the theme settings in theme_mods_kadence-child, they are stored under kadence_global_palette in the wp-options database table.

Still haven't found a way to "Sync" all customizer settings tho. I've been reading about what Pat J said in the first comment, but couldn't crack it yet.

UPDATE (DECEMBER 23 2021)

I finaly solved it! Answer bellow !

  • If I was developing this, I'd start by looking at using the update_option_theme_mods_{$theme} action hook to update a network option when your theme mods are updated, and then pulling that network option's data back out with the theme_mod_{$name} filter.

Finally Solved it! If you are going to use this code make sure to change the options names to the ones that your theme uses (change "theme_mods_kadence-child" and "kadence_global_palette").

I used get_option to get the recently saved data, then I looped through all sites and used update_option to set the new data on all subsites. Finally I used the customize_save_after action so this function activates just after the new customizer data is saved.

add_action( "customize_save_after", "update_customizer_networkwide");
function update_customizer_networkwide () {
    // Get current theme mods
    $theme_mods_kadence = get_option("theme_mods_kadence-child");
    $global_palette = get_option("kadence_global_palette");


    // loop through all sites and set new theme mods
    $sites = get_sites();
    foreach ($sites as $site) {
        switch_to_blog( $site->blog_id );

        update_option("theme_mods_kadence-child", $theme_mods_kadence);
        update_option("kadence_global_palette", $global_palette);
        
        restore_current_blog();
    }
}

Hope this helps some of you!

  • I'm glad you found a solution. Be aware, though, that on a large Multisite installation, switch_to_blog() can start to slow things down. I'd still recommend saving the data in a network option, which can be accessed from any site (see update_site_option() and its relations).

    Thank you so much! I will look into it. It should work with update_site_option() and get_site_option(). Dec 25, 2021 at 21:40
