我正在开发一个移动应用程序，允许用户记录一些关于他们最喜欢的纪念碑的数据。现在，当用户为他们的纪念碑拍照时，会立即记录纬度和经度值。给我两个不同的值。
然后用户将这些数据与我的 PostGreSQL 数据库同步。我想在我的网站服务上处理这些数据。
我想要的只是一个简单的地图插件，它将获取与用户相关的每个（就像一个 foreach 循环）记录（纪念碑的名称、纬度和经度）并将其显示在带有图标标记的地图上。
例如，您可以在加的夫拥有一座最喜欢的纪念碑，在伦敦拥有一座。您的帐户地图上会显示两个标记，当您单击它们时，会弹出“卡迪夫博物馆”和“伦敦眼”。
我在 Google 上尝试了多次搜索，但无济于事。
有没有人实现过类似的东西？我很擅长 PHP 或 JQuery 或两种解决方案！
这是您可以传递多个经纬度组合以为每个用户位置添加标记的代码。
对循环中需要的每个标记重复此代码以遍历位置数组。
t.push('Location Name 1');
x.push(33.84659); // you can write like x.push(<?php echo $userloc[0]['lat']?>)
y.push(-84.35686);
h.push('<p><strong>Location Name 1</strong><br/>Address 1</p>');
完整的代码如下。
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() { initialize(); });
function initialize() {
var map_options = {
center: new google.maps.LatLng(33.84659,-84.35686),
zoom: 14,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var google_map = new google.maps.Map(document.getElementById("map_canvas"), map_options);
var info_window = new google.maps.InfoWindow({
content: 'loading'
});
var t = [];
var x = [];
var y = [];

t.push('Location Name 1');
x.push(33.84659);

t.push('Location Name 2');
x.push(33.846253);
y.push(-84.362125);
h.push('<p><strong>Location Name 2</strong><br/>Address 2</p>');
var i = 0;
for ( item in t ) {
var m = new google.maps.Marker({
map: google_map,
animation: google.maps.Animation.DROP,
title: t[i],
position: new google.maps.LatLng(x[i],y[i]),
html: h[i]
});
google.maps.event.addListener(m, 'click', function() {
info_window.setContent(this.html);
info_window.open(google_map, this);
});
i++;
}
}

此代码可能会对您有所帮助。你可以在这里看到它的工作演示（http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=-33.866603&lon=151.207108&setLatLon=Set）
