我一直在开发 URL 的做法:https ://developers.google.com/maps/articles/phpsqlinfo_v3并且它可以工作,但在另一个示例中,我需要在单击显示的标记时出现相同的窗口 HTML 表单当我使用代码定位我的位置并将该信息保存到 MySQL 数据库中时映射。我正在使用下面的代码,但 HTML 表单窗口似乎没有保存地理位置数据。
这是网页中使用的代码:phpsqlinfo_add.html(URL 示例的类似名称:https ://developers.google.com/maps/articles/phpsqlinfo_v3 ) 其他补充网页:phpsqlinfo_addrow.php 和 phpsqlinfo_dbinfo.php 类似到例子。
代码:phpsqlinfo_add.html
