我正在为这个拔头发。我正在尝试在我正在构建的 wordpress 主题中创建一个短代码，当使用时，会显示用户的推文。
我在这里使用安德鲁·比格特（Andrew Biggart）提供的代码 https://github.com/andrewbiggart/latest-tweets-php-o-auth 来创建Twitter提要。
这是我的代码是如何设置的，我在我的主题根目录中有一个名为"tweets.php"的 php 文件，这是我设置消费者密钥等的地方 - 现在我已经对这些进行了硬编码，以便我可以让它工作。完整的 php 代码如下所示：
<?php
/**
* Twitter feed which uses twitteroauth for authentication
*
* @version 1.0
* @author Andrew Biggart
* @link https://github.com/andrewbiggart/latest-tweets-php-o-auth/
*
* Notes:
* Caching is employed because Twitter only allows their RSS and json feeds to be accesssed 150
* times an hour per user client.
* --
* Dates can be displayed in Twitter style (e.g. "1 hour ago") by setting the
* $twitter_style_dates param to true.
*
* You will also need to register your application with Twitter, to get your keys and tokens.
* You can do this here: (https://dev.twitter.com/).
*
* Don't forget to add your username to the bottom of the script.
*

我还有一个名为twitteroauth的子目录，其中包含相关文件（直接取自Andrew Biggart的github页面）
最后，在我的函数中.php我有以下代码来创建简码：
function twitter_feed( $atts ){
get_template_part('tweets');
}
add_shortcode( 'tweets', 'twitter_feed' );
这个想法是，当用户写[推文]时，它会显示最新的推文。目前，我只是想通过对所有用户信息进行硬编码来使其工作，但现在它只是输出日期"1 月 1 日凌晨 1.00"，并链接到用户的 Twitter 帐户。
我不知道我哪里出错了，但我也不知道如何调试它，所以任何正确方向的帮助将不胜感激！
你可以
试试这个，它可能会解决你的问题，因为get_template_part基本上反应像PHP's require，它不会返回，而是立即回显被调用的内容。
add_shortcode('twitter_feed', 'fn-twitter_feed');
function fn-twitter_feed($attr, $content)
{
ob_start();
get_template_part('path/to', 'tweets');
$ret = ob_get_contents();
ob_end_clean();
return $ret;
}
