带有 ACF Google 地图的多个标记

Multiple Marks with ACF Google Map

我正在尝试制作一个显示多个自定义标记的 Google 地图。我目前有一个名为 'Map' 的转发器字段设置,在该转发器中有一个名为 'google_map' 的 Google 地图和一个名为 'description'.

的描述文本框

我使用了 ACF Google 地图页面中的代码,但它只显示一个标记。

<?php if( have_rows('map') ): ?>
<div class="acf-map" data-zoom="16">
    <?php while ( have_rows('map') ) : the_row(); 

        // Load sub field values.
        $location = get_sub_field('google_map');
        $title = get_sub_field('description');
        $description = get_sub_field('description');
        ?>
        <div class="marker" data-lat="<?php echo esc_attr($location['lat']); ?>" data-lng="<?php echo esc_attr($location['lng']); ?>"></div>

        </div>
<?php endwhile; ?>
</div>

谁能帮我解决这个问题?

我使用了此页面中的所有代码:https://www.advancedcustomfields.com/resources/google-map/

但是当我使用 'Helper Code' 时,我得到的地图是灰色的,根本不显示。所以我改用了这段代码:
