将变量从一页传递到下一页 [英] Passing a variable from one page to the next page

问题描述

我正在开发问题与解答；在网站的答案网站上，向用户显示页面上的五个难题，并在用户尝试页面上的问题时使用JavaScript计算分数.分数保存在Javascript变量score中.我有这样的分页系统:

I am developing a Question & Answer website where a user is presented five puzzles on a page and the score is calculated using JavaScript as he attempts the questions on the page. The score is saved in a Javascript variable score. I have a paging system like this:

现在，当用户单击 3 时，我想将变量score发送到下一页，每个这样的页面上都有require scoreUpdateInDatabase.php，以便获得上一页的得分该数据库永久存在，下面的PHP脚本向他提出了接下来的5个问题.

Now when the user clicks on 3 I want to send the variable score to the next page, where I have require scoreUpdateInDatabase.php on each such page such that the score of previous page is made permanent to the databse and the following PHP script presents him the next 5 questions.

如何安全地传递该score变量?我不能使用GET，因为用户会对其进行修改.即使可以修改POST数据，但我仍然对POST感到满意，但我只希望获得最低的安全性.

How can I pass that score variable in secure way? I can't use GET because the user will modify it. I am satisfied with POST if this can be used, even though POST data can be modified but I just want minimal security.

P.S..请不要建议拨打AJAX电话，我会在一侧发送score，而在返回时会发出接下来的5个问题.我不想使用AJAX刷新内容，因为它是

P.S. Please do not suggest making AJAX call where in one side I will send score and while returning carries next 5 questions. I don't want to use AJAX to refresh content because it is not SEO friendly.
