我有一些很直接的代码,但出了点问题.以下代码
$title = $_POST['templatename'];
$user = $_POST['username'];
$selectedcoordinates = $_POST['templatestring'];
$title = trim($title);
$user = trim($user);
$filename = $title . "_by_" . $user;
var_dump($title);
var_dump($user);
var_dump($filename);
返回:
string(11) "Single Tile"
string(6) "Author"
string(21) "Single Tile_by_Author"
值来自HTML表单.为什么不"Single Tile"成为"SingleTile"？
我正在尝试设置一个简单的页面,使用Google Maps API在某个位置显示标记.不过我不是这个代码,这是基于谷歌的示例代码获取标记在这里.我改变了来源
"https://maps.googleapis.com/maps/api/js?key=API_KEY&sensor=false"
至
"http://maps.google.com/maps/api/js?sensor=false"
因为这里建议避免使用API密钥.var标记声明是从谷歌这里复制的.我的标记出现什么必须改变？
