我现在搜索了几个小时，但找不到任何解决方案。我希望你能帮助我。
我创建了一个网站并使用xampp对其进行了测试，并且一切正常，但是现在我将其上传到服务器上，并且我意识到var now = Date.now();
var 24hoursago = now - ...;
var ref = firebase.database().ref("yourSpecificNode");
var query = ref.orderByChild("timestamp").startAt(24hoursago).end(now);
query.once("value").then(function(snapshot) {
snapshot.forEach(function(user) {
user.ref.update({ yourSpecificProperty: "0" });
});
});
不起作用。
这是我的index.php的代码：
session_start()如果我加载页面，将不会创建会话ID，但是如果我在localhost上测试完全相同的代码，它将起作用。 我认为服务器出现问题，并上传了一个包含以下代码的文件：
<?php
session_start();
echo session_status()."<br>";
echo "SessionID: ".session_id();
error_reporting(E_ALL & ~E_NOTICE);
?>

$(document).ready(function(){
// Add smooth scrolling to all links
$("a").on('click', function(event) {

var hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll

$('html, body').animate({

我现在完全困惑了，不知道我犯了什么错误。
有人可以帮我吗？
谢谢！

执行以下代码并找到session.save_path
<?php
phpinfo();
?>
只需为此路径添加正确的权限
