开发WordPress主题：模板文件与条件标签该如何抉择？

Hey fellow WordPress dev! I totally get why you’d want to switch to conditional tags here—cutting down on duplicate code is always a win, just like leveraging template parts. Let me break down how to implement this cleanly:

First, let’s recap your current setup to align on the goal:

• singular.php: Handles single posts/pages, shows full content + comments
• home.php: Handles the blog homepage, shows full content (no comments)
• index.php: Catches all other cases, shows post excerpts

Instead of maintaining three separate files with overlapping code, you can consolidate this logic into a single base template (I’d recommend using index.php as your core file, or keep the other templates if you prefer organizational structure—but centralize the content logic).

Here’s the conditional tag implementation: #

Drop this code into your base template file where you want to display post content:

// Check if we're on a single post/page
if ( is_singular() ) {
    // Display full post content
    the_content();
    // Load the comments template
    comments_template();
} 
// Check if we're on the blog homepage
elseif ( is_home() ) {
    // Display full post content (no comments)
    the_content();
} 
// All other archive/non-specific pages
else {
    // Display post excerpt
    the_excerpt();
}

Why this approach shines: #

• Less duplicate code: No more copying the the_content() call across singular.php and home.php—all your content display logic lives in one place.
• Easier maintenance: If you ever need to tweak how full content is rendered (like adding a custom read-more button or wrapping it in a specific div), you only have to edit one section instead of multiple files.
• Consistent behavior: You avoid accidental inconsistencies that creep in when updating separate template files independently.

If you still want to keep separate template files for organization, you can even have singular.php and home.php load the core logic from a template part (e.g., get_template_part( 'content', 'main' )) where you’ve placed the conditional code above—this combines clean file structure with minimal code duplication.
