Question

登录后，我用登录的用户名存储会话变量，然后重定向到/dashboard/index.php。稍后，我在应用程序中单击菜单链接，该菜单链接重定向到/dashboard/kanboard/index.php，而$_SESSION['user']仍在此处，但是如果我在浏览器（或kanboard菜单链接）中按F5键，则该方法将检查{{1} } exist返回false并重定向到登录页面。这种奇怪的行为不会在其他页面上发生，例如$_SESSION['user']，在这里我可以重新加载页面而不会丢失会话变量。显然这些文件非常相似。

dashboard / index.php

/dashboard/index.php

dashboard / kanboard / index.php

$path = $_SERVER['DOCUMENT_ROOT'];
$titulo = "Index";

    include $path.'/dashboard/includes/header.php';
    ?>

    <script>
      $(document).ready(function() {
        var index = new Index(JSON.parse('<?php echo getJSONUser()?>'));
      });

编辑：在我将整个项目移至仪表板文件夹之前，这两个页面都工作正常。在它们直接出现在www / html上之前，并包括相对路径，而不是绝对路径。

编辑2 ：我所做的另一个更改是在Centos 7中使用PHP 7.3.3创建Vagrant机器，并将整个项目移入其中。在此之前，整个项目可以在另一台装有Debian，相同版本的Apache和PHP 7.3.1的服务器上正常运行。

Answer 1

首先，您的userIsAuth()函数名称错误，因为其中仅包含非常简单的身份验证。

其次，您需要先开始会话，然后再进行其他操作，例如：

if(session_id() === '') {
    session_start();
}

在每个页面的HTML之前添加该代码，并按如下方式更改userIsAuth()函数：

function userIsAuth()
{
    return (isset($_SESSION['user']) && !empty($_SESSION['user']));
}

您的userIsAuth()函数现在将像以前一样返回一个布尔值，但是PHP脚本的行要少得多。

页面重新加载后丢失会话变量
