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);
else : // not bookmarked, add
Is there a more official way of checking the current relationship array, and if it exists, removing it?
Here is the answer:
$updated_bookmarks = $current_bookmarks;
