WordPress Template Hierarchy

Master WordPress Template Hierarchy on AlexHost

Why leverage Template Hierarchy on AlexHost? WordPress’s Template Hierarchy decides which PHP file renders your site’s pages, offering flexibility to customize blogs, e-commerce stores, or custom post types. Hosted on AlexHost’s NVMe-powered VPS with root access, you can tweak templates for lightning-fast, tailored sites. This guide explains the hierarchy and how to customize it on AlexHost for 2025.

What is WordPress Template Hierarchy?

The Template Hierarchy is a set of rules that WordPress follows to choose which template file(s) to use when rendering a page. These templates are stored in your theme folder and allow WordPress to dynamically generate the correct layout and design based on the type of content being displayed.

For example:

• When displaying a single blog post, WordPress will first look for a template called single.php. If it doesn’t find that, it moves down the hierarchy, looking for alternatives like index.php.
• When displaying a category page, WordPress will first look for category-slug.php or category-ID.php, and so on.

Basic Template Files in WordPress

Every WordPress theme has a few essential template files. Here are the most common ones:

• index.php: The fallback template for all pages if no other more specific templates are available.
• header.php: Defines the header section of your site (e.g., logo, navigation).
• footer.php: Defines the footer section of your site (e.g., copyright information, footer widgets).
• single.php: Displays single blog posts.
• page.php: Displays individual pages.
• archive.php: Displays archive pages (e.g., categories, tags, authors).
• category.php: Displays category archive pages.
• tag.php: Displays tag archive pages.
• search.php: Displays search results pages.
• 404.php: Displays a 404 error page when a page is not found.

How WordPress Template Hierarchy Works

WordPress determines which template to use based on the type of content being requested. Let’s go over some common types of pages and how WordPress selects the template:

1. Single Post (single.php)

When displaying a single post, WordPress will look for the following templates in this order:

1. single-{post-type}.php (for custom post types, e.g., single-product.php)
2. single.php
3. index.php

2. Page (page.php)

When displaying an individual page (like an About Us or Contact page), WordPress will follow this order:

1. custom-page-slug.php (if the page has a custom template)
2. page-{slug}.php (e.g., page-about.php)
3. page-{ID}.php (e.g., page-2.php)
4. page.php
5. index.php

3. Category Archive (category.php)

For category archive pages (e.g., a list of posts in a specific category), the hierarchy is as follows:

1. category-{slug}.php (e.g., category-news.php)
2. category-{ID}.php (e.g., category-3.php)
3. category.php
4. archive.php
5. index.php

4. Tag Archive (tag.php)

For tag archive pages, WordPress uses:

1. tag-{slug}.php (e.g., tag-recipes.php)
2. tag-{ID}.php
3. tag.php
4. archive.php
5. index.php

5. Custom Post Types

Custom post types can have their own templates. WordPress looks for:

1. single-{post-type}.php (e.g., single-product.php)
2. single.php
3. index.php

Similarly, for custom post type archives:

1. archive-{post-type}.php (e.g., archive-product.php)
2. archive.php
3. index.php

6. Author Archive (author.php)

For author pages, WordPress follows this hierarchy:

1. author-{nicename}.php (e.g., author-john.php)
2. author-{ID}.php
3. author.php
4. archive.php
5. index.php

7. Search Results (search.php)

When displaying search results, WordPress uses the following order:

1. search.php
2. index.php

8. 404 Error Page (404.php)

When a page is not found, WordPress uses:

1. 404.php
2. index.php

9. Date Archive (date.php)

For date-based archives, WordPress uses:

1. date.php
2. archive.php
3. index.php

10. Home Page

WordPress offers two options for the home page: the blog index or a static page.

• For the blog index:
  1. home.php
  2. index.php
• For a static front page:
  1. front-page.php
  2. home.php
  3. page.php
  4. index.php

Visual Representation of the Template Hierarchy

Here’s a simplified visual flow to better understand the hierarchy:

• Single Post: single-{post-type}.php → single.php → index.php
• Page: custom-page-slug.php → page-{slug}.php → page.php → index.php
• Category Archive: category-{slug}.php → category.php → archive.php → index.php
• Tag Archive: tag-{slug}.php → tag.php → archive.php → index.php
• Author Archive: author-{nicename}.php → author.php → archive.php → index.php
• Search Results: search.php → index.php
• 404 Error: 404.php → index.php
• Home Page: front-page.php → home.php → index.php

Customizing the Template Hierarchy

You can create custom templates by following the naming conventions of the hierarchy. For example, to create a custom template for a specific category (e.g., “News”), create a file named category-news.php and place it in your theme folder. WordPress will automatically use this template when displaying posts from the “News” category.

Additionally, you can override default templates by creating more specific template files, such as single-product.php for a custom post type or page-about.php for a specific page.

Tips for Working with the Template Hierarchy

1. Use Conditional Tags: You can use conditional tags like is_single(), is_page(), or is_category() within index.php or other templates to apply specific code to certain types of content.
2. Template Parts: Use get_template_part() to include reusable code snippets (e.g., a common header or footer) in multiple templates.
3. Child Themes: If you’re making changes to an existing theme, create a child theme so you can modify templates without affecting the original theme files.
4. Debugging: If you’re unsure which template WordPress is using for a particular page, you can use plugins like What The File to find out.
