GPS位置保存在两个post meta字段上：geo_latitude 和geo_longitude.

您可以使用这些元值在Google地图上绘制帖子作为标记。

例如，使用Google Maps API，您可以有如下模板：

<h1>Posts on map</h1>

<div id="map" style="height: 400px;"></div>
<script>

    // init map with the values you need
    function initMap() {
    var map = new google.maps.Map(document.getElementById(\'map\'), {
        zoom: 1,
        center: {lat: 0, lng: 0}
    });


    // get all posts that have meta_key geo_latitude
    <?php $query = new WP_Query( array( \'meta_key\' => \'geo_latitude\' ) ); ?>
    <?php while ( $query->have_posts() ) : $query->the_post(); ?>
        <?php 
            // get latitude and longitude from post meta
            $geo_latitude = get_post_meta( get_the_ID(), \'geo_latitude\', true );
            $geo_longitude = get_post_meta( get_the_ID(), \'geo_longitude\', true ); 
        ?>
        <?php if(!empty( $geo_latitude ) && !empty( $geo_longitude )): ?>
            var pos = {lat: <?php echo $geo_latitude; ?>, lng: <?php echo $geo_longitude; ?>};
            var marker = new google.maps.Marker({
              position: pos,
              map: map,
              title: \'<?php the_title(); ?>\'
            });
        <?php endif; ?>
    <?php endwhile; ?>
    <?php wp_reset_postdata(); ?>
  }
</script>
