我想要你們的幫助。我編寫了允許用戶使用'click'函數創建標記（使用infowindow）的代碼，該函數將緯度/經度和其他信息保存到MySQL數據庫中，然後該數據庫將被調用以在地圖上顯示標記。當你點擊地圖時，它會創建一個標記，但不會將infowindow中的信息保存到數據庫中。我遵循谷歌地圖開發人員指南的指南，但仍然無法實現。我甚至三重檢查，以確保我的MySQL登錄細節工作正確，但仍然沒有。保存谷歌地圖標記onClick到數據庫
下面是代碼的地圖本身：

var latlng = new google.maps.LatLng(37.4419, -122.1419);
var options = {
zoom: 13,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map-canvas"), options);
var html = "<table>" +

這是應該的信息保存到數據庫（phpsqlinfo_addrow.php）：
<?php
require("phpsqlinfo_dbinfo.php");
// Gets data from URL parameters
$name = $_GET['name'];
$address = $_GET['address'];
$lat = $_GET['lat'];
$lng = $_GET['lng'];
$type = $_GET['type'];
// Opens a connection to a MySQL server
$connection=mysql_connect ("localhost", $username, $password);
if (!$connection) {
die('Not connected : ' . mysql_error());
}
// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
die ('Can\'t use db : ' . mysql_error());
}
// Insert new row with user data
$query = sprintf("INSERT INTO markers " .
" (id, name, address, lat, lng, type) " .
" VALUES (NULL, '%s', '%s', '%s', '%s', '%s');",
mysql_real_escape_string($name),
mysql_real_escape_string($address),
mysql_real_escape_string($lat),
mysql_real_escape_string($lng),
mysql_real_escape_string($type));
$result = mysql_query($query);
if (!$result) {
die('Invalid query: ' . mysql_error());
}
?>
第一錯URL <腳本類型= 「文本/ JavaScript的」 SRC = 「http://maps.googleapis.com/maps/api/js？傳感器=假」> Shulod是<腳本類型=」 text/javascript「src =」http://maps.googleapis.com/maps/api/js?sensor=false「> –

@alkis它沒有給我任何錯誤消息，所以我不知道要修復什麼。 –
