Exclude Posts From Loop After Today's Date

Hi

I’ve had a search round the forum and cant seem to find anything about this!

Im using WordPress to list upcoming events on a page.

I’ve created a custom field ‘event-date’ which holds a date in the future when the event will happen.

I’ve ordered the loop to show the closest date at the top of the list but now I need to automatically remove posts for events that have already passes allowing the next event to move to the top of the list.

Here’s an example of my page…
http://www.our-pub.co.uk/Pubs/Duke2.php

Here’s the loop i’m currently using…

<?php
$posts = get_posts('category=3&author=23&numberposts=3&order=ASC&orderby=event-date');
foreach ($posts as $post) : start_wp(); ?>

Any help would be very much appreciated! I’ve been trying to solve this for ages but now I’m really out of ideas!

Thanks,
Bruce
