Hi Yigit,

thanks for your message and the copy-and-paste example on how to activate ALB for LearnDash pages.
Allow me to add the following line of code, which activates ALB on the “topics” level:

$supported_post_types[] = ‘sfwd-topic’;

Strangely enough, LearnDash’s custom taxonomies for courses and lessons are plural (sfwd-lessons, sfwd-courses), whereas the taxonomy for the lowest level of content, the topics, are labelled as singular (sfwd-topic).

So if you are using LearnDash, the whole code to go into your functions.php should read like this:

function avf_alb_supported_post_types_mod( array $supported_post_types )
{
  $supported_post_types[] = 'sfwd-lessons';
  $supported_post_types[] = 'sfwd-courses';
  $supported_post_types[] = 'sfwd-topic';
  return $supported_post_types;
}
add_filter('avf_alb_supported_post_types', 'avf_alb_supported_post_types_mod', 10, 1);

Best regards,
Sebastian
