Taxonomies are not saved via the frontend. But it works in the backend. Why?

  I would like to use this function to activate my taxonomies via a true/false field. And it works perfectly in the backend.

  function update_post_taxonomy( $post_id ) {
  $myfield = get_field('my_field_name');
  if( $myfield ) {
  wp_set_object_terms($post_id, 'myterm', 'mytaxonomy', true);
  } else if ( empty( $myfield ) ) { 
  wp_remove_object_terms( $post_id, 'myterm', 'mytaxonomy', true );
  }
  }
  add_action( 'acf/save_post', 'update_post_taxonomy', 10 );
  

  But unfortunately not in the frontend via acf_form().
  Could someone help me here? Thanks!

  And once again I answer myself 😉
  I forgot the $post_id inside the acf-field. This is how it works perfectly:

  function update_post_taxonomy( $post_id ) {
  $myfield = get_field('my_field_name', $post_id);
  if( $myfield ) {
  wp_set_object_terms($post_id, 'myterm', 'mytaxonomy', true);
  } else if ( empty( $myfield ) ) { 
  wp_remove_object_terms( $post_id, 'myterm', 'mytaxonomy', true );
  }
  }
  add_action( 'acf/save_post', 'update_post_taxonomy', 10 );
