如何进行查询以便显示所有产品，但缺货除外，但如果元字段是“可见的”，则显示商品和缺货商品？

由于

function test_function($query) {
    if (!$query->is_main_query() || is_admin()) {
        return;
    }

    if ($outofstock_term = get_term_by('name', 'outofstock', 'product_visibility')) {
        $tax_query = (array) $query->get('tax_query');

        $tax_query[] = array(
            'taxonomy' => 'product_visibility',
            'field' => 'term_taxonomy_id',
            'terms' => array($outofstock_term->term_taxonomy_id),
            'operator' => 'NOT IN'
        );

        $query->set('tax_query', $tax_query);
    }


    $meta_query = array(
        array(
            'key'       => 'test_visibility',
            'value'     => 'hidden', 
            'operator'  => 'NOT LIKE'
        )
    );

    $query->set('meta_query', $meta_query);
}

add_action('pre_get_posts', 'test_function');
