Thanks so much, this allows for so many possibilities. Altering the where clause is really powerful.

Question though: if I only want it to apply to one get_posts() and no others, or, say have different get_posts()’s on different parts of the theme have different where filters, should I do something like:

function filter_where( $where = '' ) {
	// posts in the last 30 days
	$where .= " AND post_date > '" . date('Y-m-d', strtotime('-60 days')) . "'";
	return $where;
}
add_filter( 'posts_where', 'filter_where' );
			$posts = get_posts(array(
				'suppress_filters' => false,
				'numberposts' => -1,
				'category__not_in' => explode(',',$subscriber->categories_excluded),
				'post_type' => $post_types_included
				)
			);
remove_filter( 'posts_where', 'filter_where' )

(removing the filter so it doesn’t affect other suppress_filter get_posts()’s)

I’m thinking this is necessary otherwise this filter will be carried out sitewide…

I ended up having filters for posts_where, post_limits, posts_orderby, posts_join, posts_groupby all working together in my plugin!

thanks for the post, it really helped!

Much appreciated,
