我目前正在一个新闻网站上工作，并使用Wordpress存档功能在一个提要中显示我的所有帖子（当你点击帖子标题时，你会被带到源网站）。我需要为这些帖子（新闻文章的来源）添加另一个元数据。.

这就是它目前的样子，我需要与日期和作者内联的源代码。

我使用高级自定义字段插件为每篇文章创建了一个自定义元框，我可以在其中输入文章的源代码。这似乎工作正常，但我不知道如何在归档页面上显示它。

这是我添加到循环归档的代码。php，因为我想在这里显示自定义字段。但什么都没发生。我从许多不同的网站上获得了这段代码，这使得显示自定义元数据看起来很容易。（这一切都是以儿童为主题的，我使用的主题是报纸）

如何修复此问题？

档案文件php：

<?php get_header();

    $td_archive_title = \'\';
    if (is_day()) {
        $td_archive_title .= __(\'Daily Archives:\', \'newspaper\' ) . \' \' . get_the_date();
    } elseif (is_month()) {
        $td_archive_title .= __(\'Monthly Archives:\', \'newspaper\') . \' \' . get_the_date(\'F Y\');
    } elseif (is_year()) {
        $td_archive_title .= __(\'Yearly Archives:\', \'newspaper\') . \' \' . get_the_date(\'Y\');
    } else {
