与 XF\Pub\Controller\AbstractController 相关的类型错误

TypeError related to XF\Pub\Controller\AbstractController

免责声明:我是 XenForo 2.X 编程新手,请放轻松。

我不知道我做错了什么...这是我目前的攻击计划,我有一段非常短的代码(下面包含一个函数),我想在使用 PHP 回调的 XenForo 页面。回调的标准是使用控制器和回复参考,如 xf:

所述
  1. \XF\Pub\Controller\AbstractController $controller 控制器 实例。从这里您可以检查请求、响应等。
  2. \XF\Mvc\Reply\AbstractReply &$reply页面标准回复 控制器。

作为页面的节点中包含的回调是 Pages\Providers::getData()。但是 运行 所以给了我 TypeError。根据我的理解,$controller 参数 1 的类型不正确是对我大喊大叫,但如何呢?我的代码甚至不需要它。任何关于如何解决这个问题的想法将不胜感激!谢谢。

<?php

namespace Pages;

class Providers
{
    /**
     * @param \XF\Pub\Controller\AbstractController $controller
     * @param \XF\Mvc\Reply\AbstractReply           &$reply
     */
    public static function getData(
        \XF\Pub\Controller\AbstractController $controller,
        \XF\Mvc\Reply\AbstractReply &$reply
    ) {
        if ($reply instanceof \XF\Mvc\Reply\View) {
                $finder = \XF::finder('XF:Thread');
                $thread = $finder->where('thread_id', 1)->fetchOne();
                $firstPost = \XF::app()->finder('XF:Post')->where('post_id', $thread['first_post_id'])->fetchOne();
                $viewParams = [
                    'title' => $thread['title'],
                    'message' => $firstPost['message']
                ];

                // return $firstPost['message'];
                $reply->setParam('providers', $viewParams);
        }
    }
}

我不知道什么是 xenforo。但是您的错误消息清楚地表明:

An exception occurred: [TypeError] Argument 1 passed to Pages\Providers::getData() must be an instance of XF\Pub\Controller\AbstractController, string given in src/addons/Pages/Providers.php on line 23

在您的代码第 23 行中,我认为是这个:

$reply->setParam('providers', $viewParams);

所以只需传递第一个参数而不是字符串,而是您拥有的实例:

$reply->setParam($controller, $viewParams);
