get_posts() no older than X days with comments enabled

I don’t think get_posts() knows how to natively query the comment status column, but I could be wrong. Should be able to get at it using the ‘posts_where’ filter. Certainly can get the results using a $wpdb method that accepts a raw SQL query. I can’t easily write SQL queries off the top of my head, so I can’t give you an accurate idea how it would really look. It is possible, so worth figuring out.

As a really crude suggestion with syntax and naming errors a plenty, something like this could be a direction to follow:

global $wpdb;
$posts = $wpdb->get_results("
  SELECT post_ID
  FROM $wpdb->posts
  WHERE comment_status = 'enabled'
  AND DATEDIFF(NOW(), publish_date) < 30");

Once cleaned up, this should give you an array of post IDs no older than 30 days in which comments are enabled.

That did the trick, thanks mate.
