Question

我想要实现的是一个商店目录，列出附近的商店，按距离排序。我设法抓住指定半径范围内的所有商店并显示它们，并计算了距离，但排序让我头疼不已！

以下是代码：

function mbdmaster324_show_stores_in_radius_outside_city_shortcode() {

  ob_start();

  $latitude = get_field('location_latitude', $post_id->ID);
  if (!isset($latitude)) $latitude = '';
  $longitude = get_field('location_longitude', $post_id->ID);
  if (!isset($longitude)) $longitude = '';

  global $wpdb, $paged, $max_num_pages;

  /**
   * Get current paged value, for pagination
   */
  if ( get_query_var('paged') ) {
     $paged = get_query_var('paged');
  } else if ( get_query_var('page') ) {
     $paged = get_query_var('page');
  } else {
     $paged = 1;
  }

  /*
   * Get option from settings, how many posts per page to display
   */
  $post_per_page = 9999;

  /*
   * Calculate offset for pagination
   */
  $offset        = ($paged - 1)*$post_per_page; 

  /*
  * Define variables
  */

  $sort           = 'ASC'; // Sort posts
  $range          =  get_field('radius', $item->ID);
  $city_name      =  get_field('city_name', $item->ID);
  $search_lat     =  get_field('location_latitude', $item->ID);
  $search_lng     =  get_field('location_longitude', $item->ID);
  $table_name     = $wpdb->prefix . 'my_geodata';
  $table_name_2   = $wpdb->prefix . 'postmeta';

 /*
  * Construct basic SQL query
  * Query will return all posts sorted by post title
  */

  $sql_query1  = "SELECT SQL_CALC_FOUND_ROWS * FROM $wpdb->posts";
  $sql_join1   = " INNER JOIN $table_name AS geo ON ($wpdb->posts.ID = geo.post_id)";
  $sql_join1_2   = "  INNER JOIN $table_name_2 m1 
                    ON ($wpdb->posts.ID = m1.post_id)";
  $sql_join1_3   = "  INNER JOIN $table_name_2 m2 
                    ON ($wpdb->posts.ID = m2.post_id)";
  $sql_where1  = " WHERE (
    $wpdb->posts.post_status = 'publish' 
    AND $wpdb->posts.post_type = 'stores' 
    AND (m1.meta_key = 'store_level' AND m1.meta_value != 'Featured')
    AND (m2.meta_key = 'store_city' AND m2.meta_value != '$city_name')
  )";
  $sql_group1  = " GROUP BY {$wpdb->posts}.ID";
  $sql_order1  = " ORDER BY $wpdb->posts.post_title $sort";
  $sql_limit1  = " LIMIT $offset, $post_per_page";

/*
 * If latitude and longitude are defined expand the SQL query
 */
if( $search_lat && $search_lng ) {
    /*
     * Calculate range
     * Function will return minimum and maximum latitude and longitude
     */
    $minmax = bar_get_nearby( $search_lat, $search_lng, 0, $range );

    /*
     * Update SQL query
     */
$sql_where1 .= " 
  AND ( 
        ( 
          (geo.lat BETWEEN '$minmax[min_latitude]' 
          AND '$minmax[max_latitude]'
        ) 
      AND (
        geo.lng BETWEEN '$minmax[min_longitude]' 
        AND '$minmax[max_longitude]'
      ) 
    ) 
  )";

}



/*
* Construct SQL query and get results
*/
$sql1   = $sql_query1 . $sql_join1 . $sql_join1_2 . $sql_join1_3 . $sql_where1 . $sql_group1 . $sql_order1 . $sql_limit1;
$query1 = $wpdb->get_results($sql1, OBJECT);

  /*
   * Calculate pagination
   */
  $sql_posts_total = $wpdb->get_var( "SELECT FOUND_ROWS();" );
  $max_num_pages   = ceil($sql_posts_total / $post_per_page);

  if ( $query1 ){
echo '<div class="w2dc-listings-block">';
echo '<div class="store-listings-container"><h3>Nearby stores</h3>';

/**
 * Loop through posts
 */
global $post;

/**
 * Calculate the distance from the location to the store
 */

  $lat2 = get_field('store_latitude', $item->ID);
  $lng2 = get_field('store_longitude', $item->ID);

  $distance = getDistance( $search_lat, $search_lng, $lat2, $lng2 );

function mysort($a, $b) {
  return strcmp($a['distance'], $b['distance']);
}

usort($option, 'mysort');

foreach ($query1 as $post):

  /**
 * Calculate the distance from the location to the store
 */

  $lat2 = get_field('store_latitude', $item->ID);
  $lng2 = get_field('store_longitude', $item->ID);

  $distance = getDistance( $search_lat, $search_lng, $lat2, $lng2 );


    setup_postdata($post);
    get_template_part( 'content', 'store-list' );



endforeach;


  }
  wp_reset_postdata(); 


  $content =  ob_get_contents();
    ob_clean();
    return $content;
}

正如我所说的那样，它的工作范围是显示正确的商店，并计算距离，但我需要的是按距离订购结果。

我试图使用usort但是我必须承认我完全不确定我在做什么！

在研究方面，我发现了一些相关信息，但无法看到如何将其应用于此案例。

非常感谢正确方向的推动。
