DigiFusion follows WordPress’s standard template hierarchy while adding its own organized structure for better maintainability and flexibility. This guide will help you understand how the theme files are organized and how they work together to create your website.
Template Hierarchy Overview
DigiFusion uses WordPress’s template hierarchy system, which determines which template file WordPress uses to display different types of content. The theme includes all essential template files to handle various content types.
Core Template Files
index.php – The fallback template that WordPress uses when no other specific template is found. In DigiFusion, this file handles the main blog listing when no more specific template is available.
header.php – Contains the opening HTML structure, head section, and site header. This file is included at the top of every page and handles responsive navigation, logo display, and essential meta tags.
footer.php – Contains the closing HTML structure and site footer. This file includes the footer widgets, copyright information, and closing body tags.
single.php – Displays individual blog posts. This template includes featured images, post meta information, author boxes, related posts, and comment sections.
page.php – Displays static pages. This template provides a clean layout focused on page content without blog-specific elements.
archive.php – Displays archive pages for categories, tags, and custom taxonomies. It shows a grid of posts with excerpts and featured images.
home.php – Specifically handles the blog posts page when you’ve set a static front page. This template displays your blog posts in a organized grid layout.
search.php – Displays search results with a clean, scannable format that helps users find relevant content quickly.
404.php – Shows a user-friendly error page when content isn’t found, including navigation options to help users find what they’re looking for.
comments.php – Handles the display of comments and comment forms with modern styling and proper validation.
sidebar.php – Contains the sidebar widget area that can be used throughout the site for additional content and navigation.
searchform.php – Provides a consistent search form design that can be used anywhere in the theme.
Template Parts Structure
DigiFusion organizes reusable template components in the template-parts directory to promote code reusability and easier maintenance.
Content Templates
content.php – The default template part for displaying posts in archives and search results. This includes post thumbnails, titles, excerpts, and meta information.
content-archive.php – A specialized version for archive pages with optimized layout and additional taxonomy information display.
content-none.php – Displays when no posts are found, providing helpful messaging and search options for users.
Page Header Component
page-header.php – A reusable component that displays page titles, descriptions, and breadcrumbs. This template part handles different page types including:
- Single posts and pages
- Archive pages
- Search results
- Author pages
- WooCommerce pages (when active)
- Custom post types
The page header automatically detects the current page type and displays appropriate information, including custom titles and descriptions set through page meta fields.
Class-Based Functionality
DigiFusion uses object-oriented programming to organize its functionality into logical classes, making the code more maintainable and extensible.
Core Classes
DigiFusion_Schema_Markup – Handles structured data markup throughout the theme. This class generates appropriate schema.org markup for different content types, improving SEO and helping search engines understand your content structure.
DigiFusion_WooCommerce – Provides complete WooCommerce integration when the plugin is active. This includes cart functionality, product displays, checkout customization, and theme-specific styling for all WooCommerce pages.
DigiFusion_Page_Settings – Manages page-specific customization options. This class allows you to override global settings on individual pages and posts, including header types, custom logos, and display options.
Template Integration
The theme files work together through WordPress hooks and actions. The header.php file includes navigation and branding, while footer.php provides site-wide footer content. Template parts are included using get_template_part() functions, ensuring consistent styling across different page types.
Each template file includes multiple action hooks that allow for customization without modifying core theme files. These hooks follow the pattern digifusion_before_[section] and digifusion_after_[section], providing extensive customization opportunities.
Responsive and Accessibility Features
All template files include responsive design considerations and accessibility features. The theme uses semantic HTML5 elements, proper heading hierarchy, and ARIA labels where appropriate. The navigation system is fully keyboard accessible and works seamlessly across all device sizes.
Customization Approach
DigiFusion’s template structure is designed to be customization-friendly. The organized file structure, extensive use of WordPress hooks, and object-oriented class system make it easy to modify functionality without breaking core features. Template parts can be overridden in child themes, and the class-based approach allows for extending functionality through plugins or custom development.
The theme follows WordPress coding standards and best practices, ensuring compatibility with plugins and future WordPress updates. Each template file includes proper escaping, sanitization, and security measures to maintain site integrity.
