Question

在这里，我有一个艰难的：我有一个运行两个插件的wordpress： - Buddypress - Wordpress精确地理定位（存储数据库中用户的经度，纬度，海拔，位置和ID）。

现在，在我的会员目录页面上，我正在显示该网站的用户。但是，我想向网站的用户展示围绕该页面的用户。

每次我们访问此页面时，为了您的信息，查看器的位置也会被加载并存储在数据库中。

插件存储： - wp_usermeta中的最后位置 - 在wp_options中访问过的所有位置 - 饼干中的当前位置

以下是测试人员数据库中随机位置的值：

a:13:{s:8:"latitude";s:10:"40.6576022";s:9:"longitude";s:18:"-73.58318349999999";s:8:"altitude";s:1:"0";s:8:"accuracy";s:4:"2859";s:16:"altitudeAccuracy";s:1:"0";s:7:"heading";s:3:"NaN";s:5:"speed";s:3:"NaN";s:10:"error_code";s:0:"";s:13:"error_message";s:0:"";s:8:"php_time";i:1449777359;s:8:"php_date";s:19:"2015-12-10 19:55:59";s:15:"php_date_format";s:11:"Y-m-d H:i:s";s:7:"user_id";i:4;}

我希望能够在用户访问页面时显示用户周围的用户。所以基本上：将位置为100米（半径）的ID显示在ID查看器的ID位置。

但是，我不知道如何在数据库中抓取任何东西。

以下是显示成员的页面代码，通常为：

<?php

/**
 * BuddyPress - Members Loop
 *
 * Querystring is set via AJAX in _inc/ajax.php - bp_legacy_theme_object_filter()

您需要使用this answer

获取坐标并与每位用户进行比较

将<?php while ( bp_members() ) : bp_the_member(); ?>替换为：

<?php 
$current_user = wp_get_current_user();
$user_location = get_user_meta($current_user->ID, 'agl_data', true);
$user_lat = floatval($user_location['latitude']); //right now it's a string, you need a float/double.
$user_lng = floatval($user_location['longitude']); //right now it's a string, you need a float/double.
while ( bp_members() ) : bp_the_member();
    $bp_location = get_user_meta(bp_get_member_user_id(), 'agl_data', true);
    $bp_member_lat = floatval($bp_location['latitude']);
    $bp_member_lng = floatval($bp_location['longitude']);

    $distance_in_meters = vincentyGreatCircleDistance($user_lat , $user_lng , $bp_member_lat, $bp_member_lng);
    if($distance_in_meters < 100){
 ?>

然后将您的<?php endwhile; ?>替换为：

<?php } ?>
<?php endwhile; ?>

如何根据Wordpress中的坐标显示用户？
