This comprehensive guide will walk you through WordPress development basics step by step, showing you exactly how WordPress works behind the scenes and providing a clear roadmap to start your development journey. By the end, you’ll have the foundation needed to build custom WordPress solutions confidently.
How Does WordPress Work?
Before you understand WordPress development, it is important that how WordPress actually functions. There are majorly three components of WordPress, which include the core, themes as well as plugins.
The core code contains all the detailed functions which make up the WordPress Content Management System. This includes functions like password strength checking, managing the admin backend as well as scheduling posts.
Just like the core function is responsible for maintaining the backend of a website, themes are majorly responsible for the front-end look as well as feel.
Majorly the WordPress admin is used for creating posts, pages as well as other site content. You can either install and activate the pre-built themes or break the box completely by going out of the way to create custom designs.
A plugin, on the other hand, is majorly used for modifying the backend or front end of a website.
Areas of WordPress Development
With WordPress development, you need to work with majorly all the components mentioned above. So let us discuss them in detail.
Themes

By understanding how theme works, you can create a website as well as single pages sites that can balance content and dynamicity. It also helps you to get more client work and delve more into theme sales.
Though you might make less money as a theme developer at the start, learning the right skills and the working process can achieve a great feat.
Plugins
Plugins are the major element in WordPress which transforms everything with just a push of a button. It gives you control over all aspects of your WordPress system and allows you to modify things according to your way.
The plugin marketplace is majorly owned by certain companies which also run the theme marketplace. WordPress currently has a free Plugin Directory with an inventory of around 60,000 plugins, and that is a great way to start.
Core
Apart from the internal WordPress theme, there are almost 624 voluntary contributors to the WordPress theme around the world. You can contribute to the WordPress core if you like however you need a certain amount of experience for this.
REST API
The REST API is a relatively new feature in WordPress and mainly creates applications based on WordPress. This includes iPhone as well as Android applications. With REST API, you can connect to any website and ask for the latest five posts.
You can also delete users, create users as well as edit categories. Thus, with REST API, you can actually use WordPress as a database for information and accordingly build your front and backend.
How to Start with WordPress Development?
The following are some of the steps that you can do in order, to begin with WordPress development.
Have a Good Grip on Coding
WordPress is known for being a content management system that does not need its users to write code or know coding. However, as a developer, you should be well aware of the basics of CSS, PHP, HTML, and JavaScript, thereby extending the functionality of the platform.
You would be required to know the basics of PHP in order to resolve the errors blogs of WordPress on the client site. Similarly, it would be best if you also had a basic understanding of JavaScript so as to create an external link on a WordPress site to automatically open in a new tab.
Additionally, you would require certain skills in HTML and CSS in order to customize a WordPress starter theme.
The following are some of the details of the Coding Languages you need to know to be a WordPress developer.
-
- CSS
Cascading Style Sheets or CSS is majorly used for styling your page as well as the content. It determines how the HTML elements are shown on the screen. This is majorly a stylesheet language that makes significant style to your website.
-
- PHP
PHP is a powerful scripting language necessary for web development and majorly works by performing tasks in the server and then sending back the requests in HTML form. It has features like variables, array functions as well as comparison operators.
-
- JavaScript
JavaScript is a web scripting language necessary for website development which is majorly involved in changing and customizing the content on a page.
-
- AJAX
AJAX, or Asynchronous JavaScript and XML, is a technique that allows you to send as well as receive data without completely reloading a page.
-
- jQuery
A well-liked JavaScript library is jQuery. This tool makes it easier to manipulate or alter a web page using JavaScript by enabling you to link numerous functions together at once. It will be simpler to read and “cleaner” code.
Read Through WordPress Resources
Once you have completed the basics of the coding, you can start reading up on WordPress-specific resources. The following are some of the resources that can help you regarding WordPress development.
WordPress Codex
This is the official manual of WordPress, which is majorly written by the developers of WordPress. It covers holistic information right from the basics to the technical aspects. For example, adding an AJAX functionality to your customized plugin.
WordPress Developer Resources
This is a list of developer resources for WordPress, which includes handbooks, code references, plugins, theme development as well as the block editor. You must have a look at it, especially if you are working on advanced WordPress sites.
Knowing the Code
This e-learning platform offers three different learning paths: one for plugin creators and two for theme developers for those who prefer training videos. This training is for experienced developers because you’ll learn how to create a plugin or theme from scratch.
Choose a Focus Area
As mentioned above, there are majorly three focus areas for WordPress developers, the core software, plugins as well as themes. If you are into dedicated offshore development, you may need to focus on core development.
Similarly, if you want to work in theme development or create individual plugins for clients, then you need to focus on plugin development.
Create a Suitable Environment for Testing
It is important that a development environment is set up. It not only enhances the development process but also helps to make up a better product. You need to set up a local environment which is essential for storing all the WordPress plugins along with the theme files.
Through testing, you can view changes in the browser accordingly. By creating a testing environment, you can collaborate with a team of other developers and accordingly debug issues before you release them in the market.
Be An Active Member of the WordPress Community
WordPress possesses one of the largest communities which is dedicated to improving the platform. By becoming an active member of the WordPress community, you can reach out to millions of members through support members and even meet them at community events and conferences.
By actively participating in the community, you can stay updated with any new updates related to WordPress, as well as announcements.
Build a Portfolio
If you want to build a career in WordPress development, it is important that you build a portfolio and provide all proof related to your skills and competencies. You can do this by developing a portfolio.
A portfolio helps you to showcase your entire work and thereby improves your chance of being hired as a full-time employee.
Develop a Technical Resume
Just like a portfolio, a technical resume plays a very important role if you want to apply for WordPress development. You can either create a resume and additionally attach your LinkedIn profile with it.
A technical resume is majorly made of certain important sections, which include educational qualifications, professional experience, projects as well as key skills. Additionally, try to make sure all the sections are clearly illustrated with the requisite skills.
Prioritize an Ideal Work Environment
Once you have all the requisite knowledge regarding WordPress and you start applying, it is important that you ask yourself questions like which projects you would want to work on, what administrative job you would be willing to do, the city and country you are comfortable to work, whether you want to work as a solo worker or as a team and whether you prefer a flexible work environment or a structured one.
Why WordPress Development Seems So Complicated at First
The Technology Stack Overwhelm
WordPress isn’t just one technology – it’s a combination of several programming languages and systems working together. When you first encounter terms like LAMP stack (Linux, Apache, MySQL, PHP), it’s natural to feel overwhelmed. The interconnected nature of these technologies makes it seem like you need to master everything at once.
Documentation Scattered Across Multiple Sources
Unlike some programming frameworks with centralized, beginner-friendly documentation, WordPress development knowledge is spread across the official Codex, developer handbooks, community blogs, and forums. This fragmentation makes it challenging to find a logical starting point and learning sequence.
The Gap Between User and Developer Perspectives
Most people start as WordPress users, comfortable with the dashboard and basic site management. However, the jump from user to developer requires understanding WordPress from a completely different angle – as a content management system built on web technologies rather than just a blogging platform.
Understanding How WordPress Actually Works
The WordPress Core Architecture
WordPress operates on a simple but powerful principle: it’s a PHP application that generates HTML pages dynamically. When someone visits your WordPress site, the server runs PHP code that queries a MySQL database, retrieves content, applies formatting rules, and outputs HTML that browsers can display.
The core WordPress files handle this process through several key components:
- The WordPress Loop is the heart of content display. It retrieves posts from the database and cycles through them, applying the appropriate template for each piece of content.
- The Template Hierarchy determines which PHP file WordPress uses to display different types of content. For example, single posts use single.php, while the homepage might use index.php or front-page.php.
- Hooks and Filters provide the plugin system that makes WordPress so extensible. Hooks let you execute custom code at specific points in WordPress processing, while filters let you modify data before it’s displayed.
The Database Structure That Powers Everything
WordPress stores all your content in a MySQL database with a specific structure. Understanding this structure is crucial for WordPress development basics:
- wp_posts stores all content types (posts, pages, custom post types)
- wp_users contains user account information
- wp_options holds site settings and configuration data
- wp_postmeta stores additional data associated with posts
- wp_usermeta contains extra user information
This relational database structure allows WordPress to maintain relationships between different types of content and users, enabling features like author attribution, categories, and tags.
The Request Lifecycle
- When someone visits a WordPress page, here’s what happens behind the scenes:
- The web server receives the request and routes it to WordPress
- WordPress loads its core files and establishes a database connection
- The system determines what type of content is being requested
- WordPress queries the database for the relevant content
- The appropriate template file is loaded and executed
- PHP processes the template, inserting dynamic content
- The final HTML is sent to the visitor’s browser
Understanding this lifecycle helps you know where and how to hook into WordPress with your custom code.
Final Thought
One of the best things about WordPress development is that it can be a great way to foster web development skills and expertise. However, you must ensure that you have a proper skill set as well as an idea of how WordPress functions so that you can excel in this field.
