if($_SERVER['HTTP_REFERER'] == "success.php") 

永远不会是真的$\u服务器['HTTP\u REFERER']
（设置时）包含URL，而不是文件名。因此，继续执行。如果执行（！empty（$\u POST））{

并将用户重定向到success.php，则显示HTML代码或以

开头的块
成功设置会话变量将获得更好的结果。设置该变量后，重定向到mainmenu.php。或者，您可以在重定向语句中使用URL参数：
header("Location: success.php?complete=yes")

然后像这样检查它：
if ($_GET['complete'] == 'yes') {
   // Redirect to the main menu

把代码放在plz上，看起来像是一个缓存页面的问题。
if ($_GET['complete'] == 'yes') {
   // Redirect to the main menu
