How would you add an exception for a specific taxonomy? Like for instance to prevent non logged in users from seeing The Events Calendar, except for events published under the category "public" (in this case events in the category "public" would be visible to both logged in and logged out users)?
Thanks!

@nikkoboy I don't even know if this filter works anymore since it's 10 years old, but if it does you could try something like:

if( class_exists('TribeEvents') && isset($wp->query_vars['post_type']) && $wp->query_vars['post_type'] == TribeEvents::POSTTYPE && !$wp->query_vars['taxonomy'] == 'tribe_events_cat' && !$wp->query_vars['terms'] == 'public' && !is_user_logged_in()) {
wp_redirect( wp_login_url( add_query_arg( $wp->query_string, '', home_url( $wp->request ) ) ) ); exit;
}

You might also check their knowledgebase, I just found this: https://theeventscalendar.com/knowledgebase/k/hide-events-of-a-category-on-the-calendar/

I hope that helps!

@jo-snips thanks for replying to my question! And so diligently! I can testify that this filter still works flawlessly, as I've been using it for the past three years. I was trying this time to fine-tune it. I will try and implement the snippet of code you kindly shared, and if needs be, I'll liaise with the team at the event calendar. Anyway, I'll update this thread once I manage to have this work on my site. Could be useful to others.
Thanks again for your help

Sounds good mate :)
