Get url not just slug

Hi,

I am listing events with my own custom php code. Im also on a multisite installation. So an event object looks like:

Array
(
    [event_id] => 12
    [post_id] => 113
    [event_slug] => event-test-should-show-up-in-events-column
    [event_owner] => 1
    [event_name] => Event Test, Should show up in events column e:1 f:0
    [event_start_time] => 13:15:00
    [event_end_time] => 13:15:00
    [event_all_day] => 0
    [event_start_date] => 2014-01-31
    [event_end_date] => 2014-01-31
    [post_content] =>
    [event_rsvp] => 0
    [event_rsvp_date] =>
    [event_rsvp_time] => 00:00:00
    [event_rsvp_spaces] =>
    [event_spaces] => 0
    [location_id] => 0
    [recurrence_id] =>
    [event_status] => 1
    [event_private] => 0
    [event_date_created] => 2014-01-16 16:29:26
    [event_date_modified] => 2014-01-16 17:00:01
    [event_attributes] => a:2:{s:30:"publish_to_university_homepage";s:1:"1";s:34:"university_homepage_featured_event";s:1:"0";}
    [blog_id] => 2
    [group_id] => 0
    [recurrence] => 0
    [recurrence_interval] =>
    [recurrence_freq] =>
    [recurrence_days] => 0
    [recurrence_byday] =>
    [recurrence_byweekno] =>
)

As you can see the only thing that helps me is “event_slug”. However, since i have subdomains, I don’t know which subdomain this event is on. Say “test.test.com/events/event-test-should-show-up-in-events-column”.

How can ask for the full URL of an event?
