If you are like me, I like to streamline stuff.
I had posed the question if it was possible for the Events+ plugin to share categories and tags as other custom post types do with regular posts.
The answer I had gotten was no, and it is not possible out of the box.
I understood that that it might require some coding, and I am no expert, no novice, but also not afraid to try.
What I found was you CAN!
In your functions.php, add the following code:
register_taxonomy_for_object_type( 'category', 'incsub_event' );
add_action( 'init', 'wpa_categories_for_events' );
register_taxonomy_for_object_type( 'post_tag', 'incsub_event' );
add_action( 'init', 'wpa_tags_for_events' );
This unfortunately adds two versions of categories, and 2 Tags to your Events. One set are custom “Event-Tags” and Event-Categories” The other set are normal WordPress tags and categories that resolve from your normal posts or other WordPress custom post types.
I will add another Blog post on how to disable the Out-Of-The-Box Categories and Tags that the WPMUDEV.org WordPress Events+ Plugin comes with.
But for now, this code should help you!
