我在我的产品页面上有一个锚定链接，链接到页面下方的一个div。div仅在有内容时显示。

是否可以基于div ID为链接编写if语句？是否存在#ID？

这是div：

<div class="upsells products" id="tab-accessories">
            <!--Change related products text-->
            <?php 
            global $post;
            //If Product Page is a Model page, display "Reccomended Accessories"
                if ( has_term( \'Models\', \'product_cat\', $post->ID ) ) {
        echo \'<h2>\' . \'Reccomended Accessories\' . \'</h2>\';
                }
            //If Product Page is an Accessories page, display "Customers Also Bought"
                if ( has_term( \'Accessories\', \'product_cat\', $post->ID ) ) {
        echo \'<h2>\' . \'Customers Also Bought\' . \'</h2>\';
                }
                ?>
        <?php woocommerce_product_loop_start(); ?>
            <?php while ( $products->have_posts() ) : $products->the_post(); ?>
                <?php wc_get_template_part( \'content\', \'product\' ); ?>
            <?php endwhile; // end of the loop. ?>
        <?php woocommerce_product_loop_end(); ?>
    </div>

        <li><a href="#tab-accessories">Accessories</a></li>
