Include All Post Types in Search

This snippet will automatically include all public post types, that have not been excluded from searches in your search results.

Code Snippet:

<?php
function pippin_include_post_types_in_search($query) {
	if(is_search() && is_main_query()) {
		$post_types = get_post_types(array('public' => true, 'exclude_from_search' => false), 'objects');
		$searchable_types = array();
		if($post_types) {
			foreach( $post_types as $type) {
				$searchable_types[] = $type->name;
			}
		}
		$query->set('post_type', $searchable_types);
	}
	return $query;
}
add_action('pre_get_posts', 'pippin_include_post_types_in_search');
?>
