非法使用 $_REQUEST。您必须使用请求 class 或 request_var() 来访问输入数据

Illegal use of $_REQUEST. You must use the request class or request_var() to access input data

有点超出我的深度。我正在将论坛提供商 'phpBB' 与我自己的站点集成,并为 phpBB 本身创建一个外部直接消息传递系统。我正处于收到此错误的阶段:

Warning: Cannot modify header information - headers already sent by (output started at /home/treeves4/public_html/pm/pm/new_pm.php:25) in /home/treeves4/public_html/pm/pm/phpBB/includes/functions.php on line 2474

Illegal use of $_REQUEST. You must use the request class or request_var() to access input data. Found in /home/treeves4/public_html/pm/pm/new_pm.php on line 43. This error message was generated by deactivated_super_global.

我已经试过 $_POST 了,但还是不行。使用 $_REQUEST_VAR 不会引发任何错误,但它会破坏脚本并且在提交信息时没有任何反应。

PHP 文件:

我认为 'superglobals' 在 php.ini 中被禁用并且 $_GET、$_POST 和 $_REQUEST 不可用。

您可以通过使用 'global' 关键字声明它们来将它们拉入范围,但我不确定。

global $_POST;

根据您引用的错误信息:使用request_var()。

https://wiki.phpbb.com/Function.request_var

http://php.net/manual/en/reserved.variables.request.php

Docs say: This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script. There is no need to do global $variable; to access it within functions or methods.

http://php.net/manual/en/language.variables.superglobals.php

伙计们干杯,事实证明对我来说很难,但在你们的帮助下我做到了。我在下面添加了编辑内容。

$_SESSION['userid'] = $user->data['user_id'];
$_SESSION['username'] = $user->data['username'];

$gettitle = request_var('title', '0');
$getrecip = request_var('recip', '0');

超级全局变量已在 phpBB 3.1 中禁用,并且 3.0.x 中的 request_var() 函数已被弃用。

您应该使用 request class,文档在 phpBB 开发维基上 - https://wiki.phpbb.com/PhpBB3.1/RFC/Request_class

@Eeji 的回答是我在大多数情况下所做的:但是,在一些罕见的情况下,使用请求 class 是不可能的,例如当您处理现有的 pre-3.1 时phpBB 实现,并且您想升级论坛而不必弄乱使用 superglobals 的 PHP 脚本,并且您不拥有、不知道或被允许更改。

出现这种情况时,您可以选择全局或以编程方式重新启用超全局变量:

全球

打开 /phpbb/config/parameters.yml 文件并将 core.disable_super_globals 键从 true 更改为 false

以编程方式

这是一个示例代码,可用于临时启用超全局变量(每个请求 范围):

// temporarily enable superglobals
$request->enable_super_globals();

// TODO: do your stuff here.

// disable superglobals again
$request->disable_super_globals();
