get_posts() and filters

Question

I've added a custom filter function for the_posts filter in a plugin.

add_filter('the_posts', 'posts_filter');
function posts_filter() { … }

This works pretty well in the main loop, that means the posts are filtered in the way I defined in the posts_filter function.

But I am calling get_posts() within an ajax request to get some posts. And there the filters aren't working. query_posts() or custom wp_query don't work too.

So the question is: How can I get posts beside the main loop which are filtered by the_posts filter?

Answer 1

the_posts does work for all queries including the main query as well as custom queries but doesn't work when using get_posts(). This is because get_posts() automatically suppresses all the filters. If you want to use the filters even when using get_posts, you can pass an extra key 'suppress_filters' => false in the array you pass as argument to get_posts()
