的index.php

Question

我试图在php会话中存储大量的POST数据。数据似乎保存没有任何问题，但当我尝试访问下一页加载时的数据时，它是未设置的。我不知道我做错了什么。这是我可以做的最小工作示例：

的index.php

<?php
session_start();
$_SESSION['roles'] = $_POST['ext_roles'];
var_dump($_SESSION);

session.php文件

<?php
session_start();
var_dump($_SESSION);

当我向index.php发布POST时，数据会按预期显示：

/var/www/default/index.php:4:
array (size=1)
  'roles' => string '00000000000000000' (length=17)

但是当我加载session.php时，我明白了：

/var/www/default/session.php:3:
array (size=1)
  'roles' => null

所有数据都不会发生，只是我真正关心的数据。如果我只是使用邮递员提交随机POST数据，它可以正常工作，但是从我尝试保存的外部源进入初始POST的数据始终设置为null或空数组。我在这里完全失败了。

这是我试图在会话中坚持的表单数据：

Answer 1

尝试改变：

$_SESSION['post-data'] = $_POST;

成：

if ($_POST) $_SESSION['post-data'] = $_POST;

否则，任何$ _GET调用都会将post-data设置为空数组。

会话变量未设置

的index.php

session.php文件
