由于某种原因，这不会更新数据库，数据库登录的值是正确的，对所有页面使用相同的 inc 文件。没有错误，只是数据库中没有更新。似乎无法为我的一生弄清楚。
<?
include("../../inc/config.inc.php");
session_start();
$loggeduser = $_SESSION['myusername'];
if(!session_is_registered(myusername)){
header("location:login/login.php");

if(is_null($userpost)) {
mysql_connect("$host", "$user", "$pwd") or die(mysql_error());

$getdata = mysql_query($server_query_sql) or die("Couldn't execute the query");
$row = mysql_fetch_array( $getdata );
