Taxonomy terms field + Polylang

Hi,

thanks for the reply. I was assuming something like that.
The funny think is, that Polylang Pro allows me to use untranslated taxonomies with the original ACF Taxonomy field.
But this has also a flaw. It saves the values properly in the field and passes them to fields in translated post, but does not save them into the taxonomy for the translated posts. To achieve this you have to open and save the translated post manually.

Currently I’m playing around with some code, that would allow to save those values into the taxonomy when saving the original post, but did not manage to get that working so far as wp_update_post alone is not doing the trick.

// get translated posts -> English
$translated_id = pll_get_post( $post_id, 'en' );

  if ( $translated_id && $translated_id !== $post_id) {

    // unhook this function so it doesn't loop infinitely
    remove_action( 'save_post', 'set_translated_categories' );

    // update the english post, which calls save_post again
    wp_update_post( array( 'ID' => $post_id ) );
  }

This gets me the translated posts and updates them, but does not write the taxonomy field values to the taxonomy. I guess I have to have alter my code with the values from the fields or the taxonomies values from the original post.

If that works, it would allow to use taxonomy fields for untranslated taxonomies (for i.e. brand names, etc.) properly with Polylang and ACF-taxonomy field.

Maybe you have an idea – I would appreciate any hint.
