WordPress has evolved into a powerful content management system used by millions of websites worldwide. In this article, we explore its architecture, customization options, and best practices for building scalable websites. Understanding the WordPress Core
At its core, WordPress is built using PHP and MySQL. It follows a modular architecture powered by themes and plugins. Key Components
Themes (control design)
Plugins (extend functionality)
Hooks (actions & filters)
Database structure How Hooks Work
Hooks allow developers to modify WordPress behavior without editing core files.
“Hooks are the foundation of WordPress extensibility.”
Example: Using an Action Hook
Below is a simple example of adding custom content to the footer:
add_action('wp_footer', function() { echo '<p>Custom Footer Content</p>'; });
You can also use inline code like add_filter() to modify existing output. Best Practice Tip
Always place custom code inside a child theme or custom plugin to prevent data loss during updates. Creating Custom Post Types
Custom Post Types (CPT) allow you to structure different types of content such as Tutorials, Showcases, and Case Studies. Basic CPT Registration Code
function create_tutorial_cpt() { register_post_type('tutorial', [ 'label' => 'Tutorials', 'public' => true, 'supports' => ['title', 'editor', 'thumbnail'] ]); } add_action('init', 'create_tutorial_cpt'); Advantages of Custom Post Types
