将Javascript.append（）变量分配给PHP变量

我如何将以下Javascipt变量“money”作为PHP变量存储在同一页面上

JS

HTML

然后使用$u请求以PHP形式检索值，即

$shipping =$_REQUEST['data-price'];

但是，警报显示我的服务器上随机CSS文件的内容，$\u请求变量数组为空，并返回空/空值

有人能帮忙吗？

试试这个，然后做一个var\u dump$\u帖子：

请看一看，因为您显然不了解php和js是如何工作的，这将使事情变得更简单

然后，您可以在此处执行哪些操作，而不是向服务器发送数据，例如：

$("input[name='shipping']").val(money); 

---

这样，您的隐藏输入将按照您的需要设置值。这就是在客户端使用js所能做的。

谢谢-这真的很有帮助。
