On your screenshot, if you select the option "Show System Fields" under the title "Custom Fields Translation", you will get some more fields that appear.
Please try checking if there is a system field (they begin with an underscore "_" ) of the same name as the ones you have checked appear. If they do, please try selecting these as "Copy" as well.
You can think of these as being the "buckets" for the field values that you have already marked previously as "Copy".
If you find them and mark them as "Copy", then go back to your post type and make a small change in one and resave the post type. Please now check if the fields copied over. Without the "system" custom field that begins with an underscore, the copied VALUE that you have already marked as "copy" has no where to go.
I'm understand you're concern about having to do this for many posts.
Could we please first focus on if these steps resolves the issue on one post...and then we can see how to apply these "in batch".
That's ok for the custom field names to be the same. What concern do you have about this? Making a "small change" is only to trigger the system to reread the translatable custom fields. The "change" can be anywhere on the post content.
$args = array(
'post_type' => 'post', // or any custom post type
'posts_per_page' => -1, // get all posts
'fields' => 'ids', // only get post IDs
);
$post_ids = get_posts( $args );
foreach ( $post_ids as $post_id ) {
do_action( 'wpml_sync_all_custom_fields', $post_id );
}
ofc this will only work ones later on new posts problem will continue I need wpml to sync custom fields automatically.
ok this will work for each post saved and synced when needed...
will try it later I have time.
function sync_custom_fields_on_save( $post_id ) {
// If this is just a revision, don't sync.
if ( wp_is_post_revision( $post_id ) )
return;
do_action( 'wpml_sync_all_custom_fields', $post_id );
}
add_action( 'save_post', 'sync_custom_fields_on_save' );
