通过WooCommerce上的WP-Query显示不正确的帖子

所以基本上我使用以下代码似乎完全把所有内容都放入查询中，但是，我仍然得到错误的产品 . 例如，我要求的产品类别为“冬季”，但仍然会收到“全季”类别的产品

这是我的代码：

add_action('pre_get_posts', 'advanced_search_query', 1000);
function advanced_search_query($query) {
if ( ! is_admin() && $query->is_main_query() && $query->is_search() ) {
    global $wp_query;
    // category terms search
    $categories = array('winter','all-season','summer','run-flat');
    $category = $_GET['category'];
    $categories = array_diff($categories,array($category));
    $taxonomy = 'product_cat';
    if (isset($category) && !empty($category)) {
        $args = array(
            'relation' => 'AND',
            array(
                'taxonomy' => $taxonomy,
                'field' => 'slug',
                'terms' => $category,
                'operator' => 'IN'
            ),
            array(
                'taxonomy' => $taxonomy,
                'field' => 'slug',
                'terms' => array($categories),
                'operator' => 'NOT IN'
            )
        );
        $query->set('tax_query', $args);
        print_r($query);
    }
    return $query;
    }
}

print_r返回以下内容：
