Hi, thanks so much for this. Helped a lot! But I need some help here, please.

I want my title to have not only the ACF field value, but also the custom taxonomy I’ve created called “pico”. When I run this code,

function my_acf_update_value( $value, $post_id, $field ) {
	
  $terms = wp_get_post_terms($post_id, 'pico');

  $pico = false;
  foreach($terms as $term)
  {
      if($term->parent)
      {
          $parent = get_term($term->parent, 'pico');
          $pico = $term->name;
          break;
      }
  }
  //Default to first selected term name if no children were found
  $pico = $pico ? $pico : $terms[0]->name;

	$new_title = $pico . ' - ' . $value;
	$new_slug = sanitize_title( $new_title );
	
	// Update post
  $my_post = array(
      'ID'           => $post_id,
      'post_title'   => $new_title,
      'post_name'		 => $new_slug,
  );

	// Update the post into the database
  wp_update_post( $my_post );
	
	return $value;
}

add_filter('acf/update_value/name=data_do_boletim', 'my_acf_update_value', 10, 3);

it gives me these error messages:

Notice: Undefined offset: 0 in /Users/Mauricio/Sites/RicoSurf/wp-content/themes/ricosurf/functions.php on line 219

Notice: Trying to get property of non-object in /Users/Mauricio/Sites/RicoSurf/wp-content/themes/ricosurf/functions.php on line 219

But when I go back and see that post, the title is perfect, exactly the way I want.

So I assume the code “is working” just not 100%. Can some one help me find out what’s wrong?
