wordpress rss提供多个标签

Question

I would like to change WordPress's RSS feed functionality to only match posts and pages that has all of the tags (not just one) when I specify multiple tags. I've already added code to include pages on top of posts.

Example URL: ~WP~/feed/?tag=holiday,halloween

I'm trying to alter the query inside the pre_get_posts action hook.

Code:

if ($_GET['tag']) {
    $tagsArray = explode(',', $_GET['tag']);

    array_push($query->tax_query, array(
        'taxonomy' => 'post_tag',
        'field' => 'slug',
        'terms' => $tagsArray,
        'operator' => 'AND',
    ));
}

Can someone point me in the right direction on how to make the query match all of the tags? Thanks!

Ok, I figured it out. Posting so others who's in the same situation can solve it.

if ($_GET['tag']) {
    $tagsArray = explode(',', $_GET['tag']);

    if (sizeof($tagsArray) > 1) {
        $query->set('tag__and', $tagsArray);
    }
}
