使用$ .post将JS变量发送到PHP脚本 [英] Using $.post to send JS variables to PHP script

问题描述

我正在尝试将Javascript变量发送到PHP脚本以更新测验游戏的分数。我已经查看了执行此操作的速记方法，即$ .post，但无法在PHP脚本中检索值。我不太熟悉哪个JS，需要我做错什么的帮助。

I am trying to send Javascript variables over to a PHP script for updating scores of a quiz game. I've looked up the shorthand method of doing this, which is $.post, but I am unable to retrieve the values in the PHP script. I am fairly unfamiliar which JS and require help as to what I am doing wrong.

这是Javascript

Here is the Javascript

function updatescore(){
            var thisgamemarks= 2300;
            var thequizid = 5;
            $.post("updatemark.php", { quizidvalue: thequizid, newmarkvalue: thisgamemarks } );
            }

和PHP

$studentnewmark = $POST['newmarkvalue'];
$thisquizid = $POST['quizidvalue'];
$thisstudentid = $_SESSION['studentid'];

推荐答案

键入$ _POST而不是$ POST。此外，在基于Windows的计算机上，您可以使用ctrl + shift + j调试js脚本-如果您的代码有任何问题，这将有所帮助。但是，您向我们展示的js代码看起来很好。

type $_POST instead of $POST. also, on a windows based machine, you can use ctrl + shift + j to debug a js script - which will help if if there's any problems with your code. but, the js code you have shown us looks perfectly fine.
