您可以使用archive_template 通过使用下面的方案，钩子来处理主题归档模板的内容，但很明显，由于模板基本上可以包含任何旧内容，因此您只能处理一小部分主题。
方案是将模板加载到字符串中($tpl_str) 在archive_template 过滤、替换内容、包括字符串（使用技巧eval( \'?>\' . $tpl_str );), 然后返回一个空白文件，以便include 在“wp-includes/template-loader.php”中，变成了一个no-op。
下面是我在插件中使用的代码的黑客版本，其目标是使用get_template_part 与归档相比，它更关心的是处理单个模板，但应该可以帮助您开始。设置是，插件有一个名为“templates”的子目录，其中包含一个空白文件（“null.php”）和内容模板（例如“content-single-posttype1.php”、“content-archive-posttype1.php”）以及用于单个案例的回退模板“single.php”，并使用get_template_part 在该目录中查找的。

为了完整起见，这里有一个后备的“single.php”，它使用自定义
get_template_part:
<?php
get_header(); ?>
<div id="primary" class="content-area">
<div id="content" class="clearfix">
<?php while ( have_posts() ) : the_post(); ?>
<?php if ( $template = myplugin_get_template( \'content-single\', get_post_type() ) ) include $template; else get_template_part( \'content\', \'single\' ); ?>
<?php
// If comments are open or we have at least one comment, load up the comment template
if ( comments_open() || \'0\' != get_comments_number() ) :
comments_template();
endif;
?>
<?php endwhile; ?>
</div><!-- #content -->
</div><!-- #primary -->
<?php get_sidebar(); ?>
<?php get_footer(); ?>
