Question

我在html页面上有两个下拉列表。数据来自mysql数据库，包含纬度，经度和地址等信息。用户从下拉列表中选择一个项目，然后单击“提交”。

在这个阶段，我想显示一个谷歌地图，并在经度和纬度放置一个标记。然后，当用户从第二个下拉列表中选择选项时，我想在该地图上添加一个标记。

目前，我可以在从第一个下拉列表中点击提交后加载地图，但我尝试删除引脚的所有选项都无效。

这是我到目前为止所获得的代码：

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
require_once('auth.php');
include ('LoginConfig.php');
include ('FetchAgentDetails.php');
include ('FetchDeliveryDetails.php');
?>

我差点忘了，这是我的第一个PHP应用程序，实际上是我的第一个Web应用程序。所以请放轻松我。指出其他错误，但请坚持这个问题。

好的，使用iframe :)和一点php

工作

参考：

echo "<iframe style =\"display: block;
    width: 800px;
    padding-top: 2px;
    height: 400px;
    margin: 0 auto;
    border: 0;\" width=\"425\" height=\"350\" align=\"center\" frameborder=\"0\" scrolling=\"no\" marginheight=\"0\" marginwidth=\"0\"
