Hi!
I want to get all posts from 1 category and then sort them ascending by date, then by time and then by location. Is that possible and how does one do it?
So far I find only solutions where you can sort by 1 meta_key. Like in this example:
$args = array("category_name" => "program", "order" => "ASC", "orderby" => "meta_value", "meta_key" => "event_date");
$query = new WP_Query($args);

The question wasn't very clear. So I'll try it again.
In 1 template I want to show all posts of the category program. A post contains besides the usual fields some custom values: event_date, event_time, location and 2 or 3 more.
I want to display the posts ordered by event_date, event_time and then by location.
What function or sql statement do I need to use in order to get an array of posts in that specific order?

Yes, I read those pages and I found so many other pages on how to search a post on meta_keys. But I can't figure out how to retrieve all posts from a single category already containing all custom values so I can sort them before I loop through in the template.

I got it (allthough i can probably leave out the joins). I still would like to know how to put the values into the array, but this is the query:
SELECT DISTINCT wposts.*
FROM $wpdb->posts wposts
JOIN $wpdb->postmeta wpostmeta ON wpostmeta.post_id = wposts.ID
JOIN $wpdb->postmeta wpostmeta2 ON wpostmeta2.post_id = wposts.ID
JOIN $wpdb->postmeta wpostmeta3 ON wpostmeta3.post_id = wposts.ID
WHERE wposts.ID = wpostmeta.post_id
AND wposts.ID = wpostmeta2.post_id
AND wposts.ID = wpostmeta3.post_id
AND wpostmeta.meta_key = 'event_date'
AND wpostmeta2.meta_key = 'event_time'
AND wpostmeta3.meta_key = 'location'
ORDER BY wpostmeta.meta_value ASC, wpostmeta2.meta_value ASC, wpostmeta3.meta_value ASC'You must log in to post.
