1. Introduction

WordPress is a powerful Content Management System (CMS) that allows users to create, manage, customize, and publish websites without developing every feature from scratch.

However, to understand WordPress professionally, it is important to understand how its internal components work together.

A WordPress website is built using several important components:

• WordPress Core

• Themes

• Plugins

• Posts

• Pages

• Media Library

• Database

• Templates

• WordPress Dashboard

Each component has a specific responsibility.

For example, themes control the visual presentation of a website, plugins extend its functionality, posts organize time-based content, and pages display permanent website information.

WordPress combines these components to generate the pages that visitors see in their browsers.

In this tutorial, we will understand each component, explore its functionality, and build a small educational website using the WordPress dashboard.

1.1 What Will You Learn?

After completing this tutorial, you will understand:

• How WordPress works internally.

• What WordPress Core is.

• What WordPress themes are.

• What WordPress plugins are.

• The difference between themes and plugins.

• What WordPress posts are.

• What WordPress pages are.

• The difference between posts and pages.

• How the WordPress database stores content.

• How the WordPress Block Editor works.

• How templates display website content.

• How WordPress generates frontend pages.

• How to manage themes, plugins, posts, and pages.

• How to create a practical educational website.

2. What Is WordPress?

WordPress is an open-source Content Management System written primarily in PHP.

It uses a database to store website information and provides an administration dashboard for managing website content and functionality.

WordPress can be used to develop:

• Business websites.

• Personal blogs.

• Educational websites.

• Portfolio websites.

• News websites.

• E-commerce websites.

• Membership websites.

• Documentation websites.

One of the main advantages of WordPress is its extensible architecture.

Instead of building every feature independently, developers can use themes, plugins, and built-in WordPress functionality.

2.1 Main Components of WordPress

The major components are:

1. WordPress Core

The main software responsible for WordPress functionality.

2. Themes

Control the visual presentation, styling, and layout of a website.

3. Plugins

Add or extend website functionality.

4. Posts

Store time-based content such as articles, announcements, and blog updates.

5. Pages

Store relatively permanent content such as About, Contact, and Services.

6. Media Library

Manages uploaded images, videos, documents, and other media files.

7. Database

Stores website content, settings, user information, and other structured data.

8. Templates

Define how different types of website content are displayed.

3. Understanding WordPress Core

WordPress Core is the foundation of a WordPress website.

It contains the essential files, functions, APIs, and systems required to operate WordPress.

Without WordPress Core, themes and plugins cannot operate as part of a normal WordPress installation.

3.1 Important WordPress Core Directories

A typical WordPress installation contains the following structure:

public_html/
│
├── wp-admin/
│
├── wp-content/
│   │
│   ├── plugins/
│   │
│   ├── themes/
│   │
│   └── uploads/
│
├── wp-includes/
│
├── index.php
├── wp-config.php
├── wp-login.php
└── wp-load.php

wp-admin/

Contains files responsible for the WordPress administration interface.

Examples of functionality include:

• Dashboard management.

• Post management.

• Page management.

• User management.

• Plugin management.

• Theme management.

wp-content/

Contains the website's customizable content and extensions.

Its major directories include:

• plugins/

• themes/

• uploads/

wp-includes/

Contains important WordPress Core libraries, functions, and internal components.

wp-config.php

Contains important configuration information, including database connection settings and other WordPress configuration values.

Security Note: Never share your wp-config.php file publicly because it may contain sensitive configuration information.

3.2 How WordPress Core Works

When a visitor opens a WordPress website:

1. The browser sends an HTTP request to the server.

2. The web server receives the request.

3. WordPress loads its core functionality.

4. WordPress loads the required configuration.

5. The database is accessed when content or settings are needed.

6. Active plugins and theme functionality participate in processing the request.

7. WordPress selects the appropriate template.

8. The server generates the HTML response.

9. The browser displays the website.

The exact execution sequence involves additional WordPress hooks, queries, caching, and server-level operations.

4. What Are WordPress Themes?

A WordPress theme controls the visual presentation of a website.

It determines how content is displayed to visitors.

Themes can control:

• Website layout.

• Colors.

• Typography.

• Header.

• Footer.

• Navigation.

• Content presentation.

• Page templates.

• Responsive styling.

For example, the same WordPress content can look completely different when you activate different themes.

The content remains stored in WordPress, while the active theme determines its presentation.

4.1 Types of WordPress Themes

WordPress themes are commonly divided into two major development approaches.

A. Classic Themes

Classic themes primarily use:

• PHP

• HTML

• CSS

• JavaScript

They commonly use PHP template files such as:

index.php
header.php
footer.php
single.php
page.php
functions.php
style.css

Classic themes can provide customization through the WordPress Customizer, theme options, and other supported interfaces.

B. Block Themes

Block themes use WordPress blocks and Full Site Editing.

They commonly include:

• HTML block templates.

• Template parts.

• theme.json.

• Block patterns.

• Global styles.

A typical block theme structure looks like this:

my-block-theme/
│
├── style.css
├── theme.json
├── functions.php
│
├── templates/
│   ├── index.html
│   ├── single.html
│   ├── page.html
│   └── archive.html
│
├── parts/
│   ├── header.html
│   └── footer.html
│
├── patterns/
│
└── assets/

Block themes allow users to edit website layouts through Appearance → Editor.

4.2 How Themes Work

Suppose you create an About page.

The page content is stored in the WordPress database.

When a visitor opens the About page:

1. WordPress identifies the requested page.

2. It retrieves the required content.

3. It selects the appropriate page template.

4. The active theme provides the design and layout.

5. WordPress generates the final webpage.

Therefore, themes control how website content appears rather than acting as the primary storage location for that content.

4.3 Where to Manage Themes

Follow these steps:

1. Log in to your WordPress dashboard.

2. Open Appearance.

3. Select Themes.

4. Review the installed themes.

5. Select Add New to browse available themes.

6. Preview a suitable theme.

7. Install the theme.

8. Activate it when ready.

For block themes, you can customize the site through Appearance → Editor.

For classic themes, the customization options may appear under Appearance → Customize.

The exact menu depends on the active theme.

5. What Are WordPress Plugins?

A WordPress plugin is a software extension that adds or modifies functionality in WordPress.

Plugins allow developers to extend a website without modifying WordPress Core.

For example, a plugin can add:

• Contact forms.

• Search functionality.

• SEO tools.

• Security features.

• Backup functionality.

• E-commerce functionality.

• Performance optimization.

• Membership systems.

• Custom post types.

5.1 How Plugins Work

WordPress plugins contain code that integrates with WordPress through its APIs and hooks.

A plugin can register functionality using:

• Actions.

• Filters.

• Shortcodes.

• Custom database operations.

• REST API endpoints.

• Custom post types.

• Administration menus.

When a plugin is activated, its registered functionality becomes available within WordPress.

5.2 Important Plugin Files

A basic custom plugin can have this structure:

my-first-plugin/
│
├── my-first-plugin.php
│
├── includes/
│   └── functions.php
│
├── assets/
│   ├── css/
│   └── js/
│
└── readme.txt

The main plugin PHP file contains the plugin header and its initialization code.

Example:

<?php
/**
 * Plugin Name: My First Plugin
 * Description: A simple educational WordPress plugin.
 * Version: 1.0.0
 * Author: Param Classes
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

function param_classes_plugin_message() {
    return 'Welcome to Param Classes WordPress Tutorials!';
}

add_shortcode(
    'param_classes_message',
    'param_classes_plugin_message'
);

This example registers a shortcode:

[param_classes_message]

When used in a WordPress page or post, the shortcode displays:

Welcome to Param Classes WordPress Tutorials!

This is a simple demonstration of how plugin functionality can be added to WordPress.

5.3 How to Install a Plugin

Follow these steps:

1. Open the WordPress Dashboard.

2. Navigate to Plugins.

3. Select Add New Plugin.

4. Search for the required plugin.

5. Review its description and compatibility information.

6. Select Install Now.

7. Select Activate.

You can also upload a compatible plugin ZIP file using the Upload Plugin option.

5.4 Examples of Common WordPress Plugins

Contact Form Plugins

Used to create contact forms and collect visitor inquiries.

SEO Plugins

Help manage SEO-related settings, metadata, and website optimization.

Security Plugins

Provide additional security features and monitoring.

Backup Plugins

Help create and restore website backups.

E-commerce Plugins

Add online store functionality, product management, and checkout features.

Performance Plugins

Provide caching, optimization, and other performance-related features.

Only install plugins from trusted developers and maintain them regularly.

6. Difference Between WordPress Themes and Plugins

Themes and plugins are both important, but they have different responsibilities.

A theme primarily controls presentation.

A plugin primarily controls functionality.

Consider a business website.

The theme controls:

• Website colors.

• Fonts.

• Header layout.

• Footer layout.

• Page design.

• Navigation presentation.

Plugins can provide:

• Contact forms.

• Security.

• SEO features.

• Online payments.

• Backup functionality.

• Additional website tools.

A professional development principle is to keep important site functionality independent of the active theme whenever possible.

This makes it easier to change the website design without losing essential functionality.

7. What Are WordPress Posts?

Posts are used to publish time-based content.

They are commonly used for:

• Blog articles.

• News.

• Announcements.

• Tutorials.

• Educational updates.

• Industry information.

By default, WordPress displays blog posts in reverse chronological order on the posts index.

The latest published post generally appears before older posts.

7.1 Important Features of Posts

1. Publication Date

Posts are associated with publication dates.

2. Categories

Categories organize posts into broader topics.

3. Tags

Tags identify specific subjects or keywords related to posts.

4. Author

Posts can be associated with an author.

5. Featured Image

Posts can have a featured image when supported by the theme.

6. Comments

Posts can support visitor comments when comments are enabled.

7. Archives

WordPress can organize posts into date-based, category-based, author-based, and other archive views.

7.2 How to Create a Post

Follow these steps:

1. Log in to WordPress.

2. Open Posts.

3. Select Add New Post.

4. Enter the post title.

5. Add paragraphs and other content blocks.

6. Insert relevant images.

7. Select a category.

8. Add relevant tags.

9. Set a featured image if appropriate.

10. Preview the post.

11. Select Publish.

Example:

Post Title: Introduction to WordPress Development

Category: WordPress Tutorials

Tags: WordPress, CMS, Web Development

Content: A beginner-friendly article explaining WordPress and its features.

8. What Are WordPress Pages?

Pages are designed for relatively permanent website content.

They are commonly used for:

• Home.

• About Us.

• Contact Us.

• Services.

• Privacy Policy.

• Terms and Conditions.

• Frequently Asked Questions.

Unlike normal blog posts, pages are not displayed according to the regular chronological blog sequence.

8.1 Important Features of Pages

1. Static Content

Pages generally contain information that does not depend on publication date.

2. Parent and Child Pages

Pages can be arranged hierarchically.

For example:

Services
│
├── Web Development
│
├── Mobile App Development
│
└── Digital Marketing

3. Page Templates

Themes can provide different layouts for different pages.

4. Navigation

Pages can be included in website navigation menus.

5. Featured Images

Pages can use featured images when supported by the theme and its templates.

8.2 How to Create a Page

Follow these steps:

1. Open the WordPress Dashboard.

2. Select Pages.

3. Select Add New Page.

4. Enter the page title.

5. Add the required content.

6. Insert suitable blocks.

7. Configure available page settings.

8. Preview the page.

9. Select Publish.

Example:

Page Title: About Param Classes

Content: Information about Param Classes, educational services, and learning objectives.

9. Posts vs Pages: Important Differences

Although both posts and pages store website content, their purposes are different.

9.1 Posts

Posts are primarily intended for regularly updated content.

Examples:

• Latest technology news.

• WordPress tutorials.

• Programming articles.

• Educational announcements.

Posts normally use categories and tags.

9.2 Pages

Pages are primarily intended for permanent website information.

Examples:

• Home.

• About.

• Contact.

• Services.

• Privacy Policy.

Pages can have parent and child relationships.

9.3 Practical Example

Suppose you are developing an educational website.

You might create the following pages:

• Home.

• About Us.

• Courses.

• Contact Us.

You might publish the following posts:

• What Is WordPress?

• WordPress Themes Explained.

• How to Install WordPress Plugins.

• WordPress Development Tips.

The pages establish the website structure, while posts provide regularly updated educational content.

10. Understanding the WordPress Database

WordPress uses a database to store important website information.

A standard WordPress installation uses MySQL or a compatible MariaDB database.

The database stores:

• Posts.

• Pages.

• Comments.

• Users.

• Website settings.

• Plugin settings.

• Theme-related options.

• Metadata.

• Taxonomy relationships.

10.1 Important WordPress Database Tables

The following are common default WordPress database tables.

wp_posts

Stores posts, pages, attachments, revisions, and other post-type records.

wp_postmeta

Stores additional metadata associated with posts and pages.

wp_users

Stores user account information.

wp_usermeta

Stores additional user information.

wp_options

Stores website settings and other options.

wp_terms

Stores taxonomy terms such as categories and tags.

wp_term_taxonomy

Stores taxonomy information for terms.

wp_term_relationships

Connects posts with taxonomy terms.

wp_comments

Stores visitor comments.

wp_commentmeta

Stores additional comment metadata.

Important: The database prefix does not always have to be wp_. It can be customized during installation.

10.2 How WordPress Stores Posts and Pages

WordPress stores both posts and pages in the wp_posts table.

They are distinguished using the post_type field.

Common values include:

• post – Blog post.

• page – Static page.

• attachment – Media attachment.

• revision – Content revision.

This is why posts and pages can share the same basic content management system while behaving differently.

11. Understanding the WordPress Block Editor (Gutenberg)

The WordPress Block Editor is the modern content editing interface.

It allows users to create content using individual blocks.

Each content element can be managed independently.

11.1 Common Block Types

Paragraph Block

Used to write normal text.

Heading Block

Used to create headings and subheadings.

Image Block

Used to insert images.

Gallery Block

Used to display multiple images.

List Block

Used to create ordered and unordered lists.

Button Block

Used to create clickable buttons.

Columns Block

Used to organize content into columns.

Group Block

Used to group multiple blocks.

Cover Block

Used to display content over a background image or color.

11.2 How Blocks Work

For example, when creating a tutorial article, you can use:

• Heading blocks for section titles.

• Paragraph blocks for explanations.

• Image blocks for screenshots.

• List blocks for instructions.

• Code blocks for programming examples.

• Button blocks for important links.

Each block can be edited, moved, duplicated, or removed independently.

11.3 Practical Block Editor Workflow

1. Open Posts → Add New Post.

2. Enter a title.

3. Add a paragraph block.

4. Insert a heading block.

5. Add an image block.

6. Insert a list block.

7. Arrange the blocks.

8. Configure block settings.

9. Preview the article.

10. Publish the content.

12. Understanding WordPress Templates

A template determines the layout used to display a particular type of website content.

A theme may provide different templates for:

• Homepage.

• Single posts.

• Pages.

• Archives.

• Search results.

• 404 pages.

For example, a single post template may display:

• Post title.

• Featured image.

• Publication date.

• Author.

• Article content.

• Comments.

A page template may use a different structure.

12.1 Templates vs Themes

A theme is the overall design system.

A template is an individual layout within that theme.

For example:

A theme may provide a complete website design with multiple templates.

One template may control blog posts, while another controls static pages.

12.2 Template Parts

Block themes can also use reusable template parts.

Common examples include:

• Header.

• Footer.

• Sidebar.

When a reusable template part is updated, the change can appear wherever that template part is used.

13. How WordPress Works Together

Now let's understand how all the major components work together.

Imagine a visitor opens a tutorial article on your educational website.

The process works as follows:

Step 1 – Browser Request

The visitor enters a website URL in the browser.

Step 2 – Server Processing

The web server receives the request and invokes WordPress.

Step 3 – WordPress Core

WordPress loads the required core functionality and processes the request.

Step 4 – Plugins

Active plugins can add functionality through their registered hooks and other supported integrations.

Step 5 – Database

WordPress retrieves the requested post and related information from the database.

Step 6 – Theme

The active theme provides the design and presentation rules.

Step 7 – Template

WordPress selects the appropriate template to display the content.

Step 8 – HTML Response

The server generates the final HTML response.

Step 9 – Browser Rendering

The visitor's browser displays the completed webpage.

This process allows WordPress to combine content, functionality, and design into one website experience.
