如何在WordPress中添加副标题并在浏览循环仅显示标题？

Hey there! Let's tackle your two WordPress issues step by step—fixing the subtitle display format and hiding post content on archive/category loops.

The default "Main Title: Secondary Title" format from the Secondary Title plugin can be easily adjusted using a PHP filter (no need to edit plugin core files, which would get overwritten on updates).

• Open your theme's functions.php file (or use a code snippet plugin like Code Snippets for safer edits) and add this code:

add_filter('secondary_title_the_title', 'custom_secondary_title_layout', 10, 3);
function custom_secondary_title_layout($combined_title, $main_title, $secondary_title) {
    // Customize the HTML structure here—this example puts the subtitle on a new line with a custom class
    return $main_title . '<br><span class="secondary-title">' . $secondary_title . '</span>';
}

You can tweak the HTML to fit your design: wrap titles in divs, add spacing, or use different text styles. The secondary-title class lets you add custom CSS later (e.g., make it smaller or grayed out).

To make loop pages (categories, archives, tags) only show titles + subtitles (no content/excerpt), you have two straightforward options:

Option 1: Use Code Snippets (No Template Edits) #

Add this code to functions.php or your code snippet plugin to suppress content on loop pages:

add_filter('the_content', 'remove_content_from_archives');
function remove_content_from_archives($content) {
    // Check if we're on an archive, category, or tag page
    if (is_archive() || is_category() || is_tag()) {
        return ''; // Return empty to hide content
    }
    return $content; // Keep content visible on single post pages
}

If your theme uses the_excerpt() instead of the_content() on loops, swap the filter to target excerpts:

add_filter('the_excerpt', 'remove_excerpt_from_archives');
function remove_excerpt_from_archives($excerpt) {
    if (is_archive() || is_category() || is_tag()) {
        return '';
    }
    return $excerpt;
}

Option 2: Edit Theme Template Files (More Direct) #

Locate your theme's loop template files (usually category.php, archive.php, or index.php if it uses a universal template). Find the section that displays post content/excerpt—it’ll look something like this:

<div class="entry-content">
    <?php the_content(); ?>
</div>

Delete or comment out the the_content() (or the_excerpt()) line. Only keep the title output (the_title()) to show just the main and secondary titles.

Pro tip: Always use a child theme when editing template files—this prevents your changes from being lost when the parent theme updates.

After making these changes, refresh your category/archive pages: you’ll see only the formatted main + secondary titles, with no post content. Single post pages will still display full content as expected.
