在此代码中，我创建了一个隐藏类型变量，默认值为false。当条件变为true时，将隐藏类型的值设置为true，然后将调用PHP脚本，并发送表单值，然后我将取消设置发布的值，它将无法再次使用现有值

我希望它

<?php
if($_POST['hid'] == "true")
{
 $name = $_POST['name'];
 echo "Posted Value : ".$name;
 unset($_POST);
 echo "Posted Value is unset".$_POST['name'];
}
?>

function validate()
{ 
  var name = document.getElementById("name").value;
  var hid = document.getElementById("hid").value;
  if(name != '')
  {
    document.getElementById("hid").value = "true";
    console.log("true");
    return true;

函数validateRegistration；简单地返回true，并允许页面在注册为OK的情况下返回true。否则，它会在页面提交客户端验证之前在页面上显示错误。如果返回true，则表单数据将发布到“registration.php”上的同一页面，该页面可能包含ifisset$_POST['elementNames']等内容，然后执行标题“Location:home.php”；如果一切顺利。
