wordpress - Ordering WP Posts by Custom Meta Key

Question

I created a WordPress custom post type to be able to create events, select the event's date, and display the date on the frontend.

I added a new meta_key in the postmeta of WP's database to store the event's date in a UNIX timestamp.

I've had no trouble creating a new WP query to output my events on my site but I am trying to figure out how to organize the events by their UNIX timestamp in the database, not by the date that WordPress created the events.

I can't seem to wrap my head around the thing.. any advice?

Answer 1

I believe your query can have

'orderby' => 'meta_value_num',
'meta_key' => 'event_timestamp' //or whatever your meta_key is
