Hi icnadmin,
Thanks for reaching out!
I need to find a way to filter and display all events authored (via user listed in author field) by logged in users.
Unfortunately there is no option for this and it would require custom development.
Here are two sample snippets that might give you an idea on how you can modify the query:
Alternatively what you can do is have a category for each author and then use the [tribe_events] shortcode to filter by category.
I also need to display attendees registered next to each event in the view.
If you are using event tickets, then you have an option built-in to do that. When editing an event, go to the Tickets section and click on the settings button. In the opening modal you will see an option to hide or show attendees on the event page.
Hope this helps, let me know.
Cheers,
Andras
