我一直在開發URL的做法：https://developers.google.com/maps/articles/phpsqlinfo_v3和它的作品，但在另一個例子中，我需要出現在同一個窗口HTML表單時，我單擊顯示在地圖上時，我使用的代碼來地理定位我的位置，並把這些信息保存到MySQL數據庫的標記。我使用下面的代碼，但HTML表單窗口一點兒也不顯得保存地理位置數據。谷歌，地圖的API-3 - 以地理定位我的位置，並將其保存到一個MySQL數據庫
這是在網頁中使用的代碼：phpsqlinfo_add.html（網址樣品的相似名稱：https://developers.google.com/maps/articles/phpsqlinfo_v3）另一個互補的網頁：phpsqlinfo_addrow.php和phpsqlinfo_dbinfo.php類似於例子。作者
