将参数从一个HTML页面传递到另一个HTML页面 [英] Pass arguments from one HTML page to the other

问题描述

我从一个HTML页面获取参数到另一个HTML页面有问题。情况是这样的：


我使用PHP和Ajax / jQuery来构建这个网站，第一页是登录表单。当有人点击按钮登录时，我发送POST请求与ajax到一个PHP脚本，将在数据库中搜索此用户/密码（我使用ajax，因为如果发生错误，我会显示一条消息无需重新加载页面）。当PHP脚本完成时，它会将用户标识返回到登录页面。


如何从登录页面转到另一个页面（例如，主页）并保持用户标识在此处使用。我知道如何使用location.href来解决这个问题，但我不想在URL中显示用户标识。

谢谢。

I am having a problem to get arguments from one HTML page to the other. The case is this:

I am using PHP and Ajax/jQuery to build this website and the first page is a login form.
When someone click in the button "login" I am sending a POST request with ajax to a PHP script that will search in the database for this user/password(I am using ajax because if an error occurs I will show a message without reload the page). When the PHP script finishes, it returns the user id to the login page.

How can I go from the login page to another page(e.g. Home) and keep the user id to use there. I know how to resolve this using location.href but I don't want to show the user Id in the URL.
Thank you.

推荐答案

尝试使用会话：

<?php
session_start(); //u have to have this on the top of your page, to be able to use session

$_SESSION["user_id"] = $user_id;

session_destroy(); //u can use this to unset the variables stored in the session. use only   after u are done using with the $_SESSION. 
?>

访问$ _SESSION变量（就像post和get）：

to access the $_SESSION variables(just like post and get):

$variable = $_SESSION["user_id"];

一旦你设置了会话，你可以在你的任何页面中使用它们，就像全局变量一样，只要您将session_start（）放在页面的开头

once u set the session u can use them in any of your page just like a global variable and as long as you put session_start() at the beginning of the page
