Show scheduled posts in archive page

Question

I'd like my archive.php page's daily view (is_day) to display scheduled posts (post_status=future). For example, if I go to mysite.com/2011/05/20 I would see all posts scheduled to appear on May 20.

The archive page's loop starts with:

if ( have_posts() )
the_post();

and ends with:

rewind_posts();
get_template_part( 'loop', 'archive' );

Do I need to make a second loop, or can I modify this single loop to show scheduled posts? If so, how? Thank you.

Answer 1

Keep things simple - leave your archive templates alone and place this in your functions.php;

if ( !is_admin() ) :
function __include_future( $query )
{
    if ( $query->is_date() || $query->is_single() )
        $GLOBALS[ 'wp_post_statuses' ][ 'future' ]->public = true;
}
add_filter( 'pre_get_posts', '__include_future' );
endif;

Essentially, it says;

If we're on a date archive, or viewing a single post, make future posts publicly visible.

As a result, WordPress behaves normally when you view archives for any given date, except now it also includes posts 'from the future'!.
