Question

The following code shows the posts made the last 30 days.
Every post I have it has a meta_key named expiring with a meta_value of 2011-10-22 for example.

In my case, I want to remove the post_date and find what posts are near to be expired. For example, today we have 2011-10-18 and I want to show all the posts that have dates from today (18) until 2011-10-21. That means 3 days after today.

Tomorrow 2011-10-19 it must show posts that may also expire in 2011-10-22.

This is how I get the value of the meta_key get_post_meta($post->ID, 'expiring', true);

This is the function I tried to edit.

<?php
function filter_where($where = '') {
    //posts in the last 30 days
    $where .= " AND post_date > '" . date('Y-m-d', strtotime('-30 days')) . "'";
    return $where;
}
add_filter('posts_where', 'filter_where');

query_posts('post_type=post&posts_per_page=10&order=DESC');

while (have_posts()): the_post(); ?>

<li><?php the_title(); ?></li>

<?php
endwhile;
wp_reset_query();
?>

Thank you for any help.

I don’t know if I understand the problem properly, but it seems you want to have this in your function:

$where .= " AND expire_date < '" . date('Y-m-d', strtotime('+3 days')) . "'";

Sort on expire_date, rather than post date, and take everything where the expire date is not later than 3 days in the future.
