Exclude child posts

Anything is possible when using the relevanssi_hit_filter filter hook. Simply create a function that removes all child posts from the search results.

Hi

I’ve been unsuccessful writing the filter.

add_filter('relevanssi_modify_wp_query', 'mod_q');
function mod_q($wp_query) {
	if (is_search()) {
		global $wp_query;
		$wp_query->query_vars['post_parent'] = 0;
	}
	return $wp_query;
}

Could you offer any guidence to simply filter out any child posts from a search.
many thanks

Relevanssi does not care about $wp_query->query_vars[‘post_parent’].

Like I said, relevanssi_hits_filter is your friend here:

add_filter('relevanssi_hits_filter', 'no_kids_allowed');
function no_kids_allowed($hits) {
    $all_children_left_behind = array();
    foreach ($hits[0] as $post) {
        if ($post->post_parent == 0) $all_children_left_behind[] = $post;
    }
    return $all_children_left_behind;
}

Thanks Mikko –
However, the filter is returning error:

PHP Fatal error: Cannot use object of type stdClass as array in …/relevanssi/lib/search.php on line 918

Fixed: Seems I just needed to return $all_children_left_behind as an array!

add_filter('relevanssi_hits_filter', 'no_kids_allowed');
function no_kids_allowed($hits) {
    $all_children_left_behind = array();
    foreach ($hits[0] as $post) {
        if ($post->post_parent == 0) $all_children_left_behind[] = $post;
    }
    return array($all_children_left_behind);
}

Many thanks – saved the day!

Ah, yes, sorry about that – the filter does expect the result in an array. Glad you got it sorted out.
