Check Relationship Field and Add/Remove

  I’m trying to create a “bookmark” button of sorts … where when the user bookmarks a post, I save it to a Relationship field. If the user then unbookmarks it, I check the relationship field and remove it from the collection of relationships.

  Adding is easy. Removing is proving to be a pain in the butt and just destroys the entire array:

  $current_bookmarks = get_field( 'webinar_bookmarks', 'user_' . get_current_user_id() );
  	
  	if ( in_array($webinar_post, $current_bookmarks) ) : // bookmarked, remove
  	
  		$key = array_search($webinar_post, $current_bookmarks);
  		unset($current_bookmarks, $key);
  	
  	else : // not bookmarked, add

  Is there a more official way of checking the current relationship array, and if it exists, removing it?

  Thanks!

  Here is the answer:

  unset($current_bookmarks[$key]);
  	
  $updated_bookmarks = $current_bookmarks;
