Exclude custom post type from search conflict with get_posts

Question

I want to hide my custom post type from search results. So, I followed the codex and used:

exclude_from_search => 'true' while registering my custom post type.

That hides the custom post type and it does not appear in search results any more.

But now I am unable to load posts using get_posts but they appear fine with WP_Query. I wonder why it is happening.

Answer 1

get_posts() uses WP_Query, so you are probably providing wrong arguments, it's worth mentioning that the function has some default arguments.

This should get all posts of the CPT myCPT:

$args = array(
    'posts_per_page' => -1,
    'post_type'      => 'myCPT',
    'post_status'    => 'any',
);
$posts_array = get_posts( $args ); ?>

Answer 2

Can you try this code?

function excludePages($query) {
   if ($query->is_search) {
      $query->set('post_type', 'post');
   }
   return $query;
}
add_filter('pre_get_posts','excludePages');
