If you want to be a WordPress developer, you must learn the key concepts and skills for the job. This blog will show you the key steps to get started and help you turn your passion for this popular content management system into a rewarding career. 

Who is a WordPress developer? 

A WordPress developer specializes in the WordPress platform. They focus on its structure and features. Their job can involve enhancing WordPress or developing plugins and themes. It may also include working with clients to build, customize, and manage WordPress sites. 

WordPress development covers a wide range of skills. Some developers contribute to the platform by creating tools. These include blocks, plugins, and themes. Others work on the WordPress Core itself. Many successful WordPress developers assist clients in building and maintaining their sites, often doing a mix of both. 

You might wonder why you need developers. WordPress is user-friendly, even for non-coders. It’s true that users can easily install plugins, select themes, create content, and adjust settings without writing code. However, technical challenges still arise. Tasks like securing a site, backing up data, and customizing a theme often require expert knowledge beyond the average user. 

In short, WordPress developers handle the complex parts of creating and managing a WordPress site. Many users lack the knowledge or time to tackle them on their own. 

What WordPress developers really do? 

WordPress developers play a key role in both enhancing the platform and helping clients achieve their website goals. Their responsibilities can vary greatly depending on the project, employer, or type of WordPress website they’re working on. Below are some of the core duties a WordPress developer may handle: 

Creating custom plugins, themes, or modules Developers build features for a client’s specific needs. This includes unique themes and advanced plugins that extend the website’s capabilities. 

Designing sitemaps or wireframes for websites: Developers often start by planning a website’s structure. They use sitemaps or wireframes as a blueprint for the site’s look and function. 

Converting a website to WordPress: Developers help clients move their sites to WordPress. They ensure a smooth transition while keeping the design and functionality intact. 

WordPress developers often redesign websites to boost speed and SEO. This improves user experience and search rankings. 

Developers regularly inspect the website’s code: They do this to find performance issues and ensure efficiency. also fix any bugs or problems that arise. 

They manage both the visible parts of the website (front-end) and the server-side processes (back-end). This ensures everything works seamlessly together. 

Managing multiple projects: Developers often juggle several projects at once, staying organized and ensuring each client’s website is progressing on schedule. 

Communicating with clients: Developers must understand client goals. They must also provide updates on the project’s status. Effective communication is key. 

Developers often meet with potential clients to discuss project ideas, offer insights, and outline how to achieve the clients’ goals. 

Ongoing support and maintenance: This includes regular security scans, backups, and fixing any technical issues that arise after a website’s launch. 

How to become a WordPress developer 

Start by learning essential web development languages like HTML, CSS, JavaScript, and PHP, which are the building block of WordPress. These are crucial for anyone becoming a WordPress developer. Set up a local development environment to practice building custom theme and plugins, and immerse yourself in the WordPress community for support and networking.  

Having foundational knowledge in coding and programming is key, as many educational backgrounds can help, whether through formal education or self-learning. Build a strong portfolio showcasing your projects to attract clients or secure employment opportunities, highlighting your coding knowledge and expertise in essential programming languages. 

Learn what you can build and customize in WordPress 

When developing in WordPress, you’re writing custom code that interacts with the core system. The great thing is, if you make a mistake, the core WordPress software stays intact. So, you can test and experiment freely without needing to reinstall it. 

As a WordPress developer, you can modify almost anything. You can change the site’s design and feel. alsocan tweak admin settings. You can even create new user profile pages. Essentially, the only limit is your knowledge and eagerness to learn. 

Here are the five main things a WordPress developer can create: 

Themes 

Themes control the layout and style of a WordPress site, giving it its overall look and “feel.” A theme is made up of several components like HTML, CSS, PHP, JavaScript, and JQuery. With over 31,000 themes available, there’s still a demand for unique designs, making it a great opportunity to create custom themes and showcase your creativity. Developing a free theme for the WordPress repository can also help you build your reputation as a developer. 

Currently, the trend is creating responsive WordPress themes. These custom themes use flexible grids, smart images, and CSS media queries to ensure that WordPress sites look great on all devices: smartphones, tablets, and large desktops. 

Plugins 

With over 54,000 plugins available in the WordPress directory, plugins are one of WordPress’s most popular features. They let users improve their website’s functions without changing the core WordPress code, making them popular with those with little or no programming experience. 

Plugin development relies heavily on PHP hooks, which allow specific functions or classes to run automatically in WordPress. There are two main types of hooks—actions and filters—and mastering both is essential if you want to build effective plugins. 

A simple yet powerful example of plugin development is Easy Google Fonts, which allows users to easily customize their site’s typography. More advanced WordPress plugins, like WooCommerce and Yoast SEO, involve complex coding and heavy use of hooks. Google Analytics Dashboard is similar, but many simpler plugins, like Search & Filter, offer great features with less complexity. 

Entire WordPress websites 

Building a complete WordPress website involves more than just selecting themes and plugins. As a web developer, you’ll integrate themes, plugins, and widgets, along with custom code (SASS, CSS, JavaScript, and PHP) to create a unique web page tailored to specific needs, whether for a client or your own project. This process is a key part of website development, requiring both technical and design expertise. 

Website builders like Bluehost WonderSuite and Squarespace make it easy to create a site. However, there is still high demand for custom web design and website development by developers who can provide fully personalized solutions. 

A tool like Bluehost Website Builder can simplify designing a stunning user interface, but creating a site requires more than just coding skills. You must be creative, understand UI/UX design, and work with template files to achieve a professional look. Additionally, using fast, secure WordPress managed hosting ensures a smooth and polished result. 

Web applications using the REST API 

A web app is dynamic software. It runs on a web server and is accessed via a web browser. This makes it compatible with any device or OS, as long as the browser supports it. Unlike traditional websites, which are mostly static, web applications are interactive and functional. Popular examples include Gmail, Google Docs, and Facebook. 

In 2015, WordPress introduced its REST API. It is a framework for communication. It lets WordPress interact with other web server applications. Think of it as a “bridge” that connects the WordPress core to external systems. 

Master the REST API’s core concepts. Then, use WordPress to build web apps. They will be more dynamic and interactive than a standard website. 

Learn a programming language 

The WordPress core uses key web languages: PHP and MySQL. Its front-end relies on HTML, CSS, JavaScript, jQuery, and AJAX. To become a proficient WordPress developer, you’ll need to understand these languages. Let’s take a closer look at what you’ll need to learn: 

HTML (especially HTML5) 

HTML, or HyperText Markup Language, is essential for creating a smooth user experience. It ensures your website displays correctly across all browsers. If your HTML isn’t valid, browsers might misinterpret your code, causing parts of your page to display incorrectly. 

HTML5 is the latest version. It has advantages over HTML4. It supports video and audio, has better JavaScript compatibility, and adds new elements. 

Valid HTML means following the correct syntax. It requires proper document structure, with elements in the right order and correctly nested. Every HTML document should start with a DOCTYPE declaration. Then, add opening `<html>` tags, a head section (with metadata like page titles), and a body section. Finally, close with the `</html>` tag. 

In HTML, there are three main types of elements: 

Flow elements: These are block-level elements that form the structure of the page, such as `<div>`, `<ul>`, and<footer>. 

Phrasing elements: These are inline elements, like `<b>` (bold), `<i>` (italics), and `<a>` (links), which can be used inside flow elements such as paragraphs. 

Metadata elements: These provide information about the document, such as the `<meta>` tags in the head section. 

For instance, a paragraph tag (`<p>`) can include inline elements like bold or italic text, but it can’t contain block-level elements like lists or divs. 

If you’re unsure if your HTML is valid, tools like the W3C HTML Validator can help. You can also use HTML cheat sheets to quickly look up correct syntax and tags as you practice. With time and patience, mastering HTML becomes much easier. 

CSS (preferably CSS3) 

Cascading Style Sheets (CSS) define your webpage’s look and layout. They control how HTML elements display on screen. With CSS, you can quickly apply consistent styles across your entire website. 

A key feature of CSS is media queries. They let you customize your site’s look on different screen sizes. This is essential for building a responsive website that adapts smoothly to devices like phones, tablets, and desktops. 

CSS uses a simple syntax made up of two components: selectors and declaration blocks. A selector targets the HTML element you want to style. The declaration block contains the styles to apply, like colors, fonts, or layout tweaks. 

The latest version, CSS3, adds several new features to the language. It adds flexible layouts, better text effects, and multi-column support, among other improvements. These updates make it easier to create modern, visually appealing websites. 

If you’re new to CSS, writing custom styles might seem intimidating at first. Luckily, you can reference a CSS Cheat Sheet to help guide you as you practice. 

To build a solid foundation, explore CSS basics on sites like BitDegree. They can teach you this essential language quickly. 

PHP 

PHP (Hypertext Preprocessor) is a powerful scripting language used in web development. It handles server-side tasks and sends the results back as HTML, which is what users see on the front-end. In simple terms, PHP file manages the back-end processes, while HTML presents the output to users after the tasks are completed. 

The WordPress core is built on PHP, along with MySQL for database management. PHP is flexible and compatible with most servers. It can run on nearly all operating systems. This makes it a popular choice for developers. 

Here are some key PHP features you’ll frequently use: 

• Variables: These are used to store information, such as strings of text or numbers. 

• Arrays: These collect data that’s assigned to a variable, allowing you to store multiple values in one place. 

• Functions: These perform tasks and return results, which can be reused or stored in variables for later use. 

• Conditionals: These allow you to define actions based on certain conditions. For example, if a statement like 1 == 1 is true, one action will occur; if false, a different response will be triggered. 

• Comparison operators compare values. Each operator (=, ==, or ===) affects how conditionals are evaluated and what results they produce. 

To build complex, OOP systems in PHP, learn about PHP classes. Classes help organize related variables and functions in a tidy and structured way. 

For more detailed information about PHP classes, you can explore the WordPress Codex page on Class Reference/WP Object Cache. 

MySQL 

MySQL is the database that stores all the content and information on a WordPress site, including posts, pages, user data, and more. Whenever content is needed, PHP retrieves it from the MySQL databases dynamically. Essentially, MySQL holds the content, while PHP acts as the bridge to display that content on your site. 

WordPress provides a set of PHP functions to safely interact with the MySQL, ensuring smooth data retrieval and updates. Some of these functions use standard SQL statements, while others rely on arrays to process information. 

For more details on how WordPress interacts with MySQL databases, you can refer to the wpdb Class on the WordPress Developer Codex. 

JavaScript 

JavaScript is a key scripting language used to enhance website interactivity. It enables you to change how content behaves on a page, such as showing text only after a user clicks a button. JavaScript transforms static HTML into an interactive web experience. 

You can embed JavaScript directly within an HTML file, and it will automatically run when the page loads. JavaScript also integrates seamlessly with CSS, giving you even more control over the look and behavior of your site. 

JavaScript mainly runs in web browsers, but it can run outside them using Node.js. This tool lets you use JavaScript for tasks like database management, mobile apps, and robotics. 

For WordPress developers, learning JavaScript is essential. Understanding how to add JavaScript correctly to WordPress is crucial, as improper use can lead to conflicts that affect the site’s performance. You can find more details on this topic in the Using JavaScript section of the WordPress Codex. 

jQuery & AJAX 

jQuery is a widely-used JavaScript library that simplifies tasks like manipulating web pages, creating animations, and managing CSS with cleaner, easier-to-read code. By learning jQuery, you can streamline large JavaScript projects and speed up development. It offers handy features like hiding HTML elements, creating sliding effects, and more.  

Additionally, AJAX (Asynchronous JavaScript and XML) is a technique that enables data transfer without reloading a page, making sites more interactive. For example, AJAX allows live search results to appear instantly without refreshing the page.  

WordPress uses AJAX for auto-saving drafts in the admin panel to prevent data loss. While both JavaScript and jQuery can run AJAX, jQuery is often preferred for its simplicity. Together, these tools help create more responsive and user-friendly websites. 

Setting up your development environment 

A well-organized development environment is crucial for efficient coding and testing. It helps speed up your workflow and ensures a smoother process when building and debugging your projects, especially when working with WordPress features like themes and plugins. 

Choosing the right code editor or IDE 

The right code editor can greatly enhance your productivity. Some popular options include: 

• VS Code: A lightweight and highly customizable editor. 

• Sublime Text: A fast and versatile editor that supports multiple languages. 

• PHPStorm: An IDE built specifically for PHP development, with WordPress support. 

Installing a local server environment 

To build and test WordPress sites, you need a local server environment. Here are some great options: 

• XAMPP: A free, cross-platform web server solution. 

• MAMP: A local server for macOS users. 

• Local by Flywheel: Tailored specifically for WordPress development. 

Utilizing debugging tools: Debugging is a critical part of development. Tools like Xdebug and WordPress’s built-in debugging features can help you quickly identify and fix issues, streamlining your workflow and enhancing website security. 

Setting up a local development environment is essential for any developer. It allows you to store and test your WordPress theme, plugin, and core files directly on your computer. While it looks like a regular website in your browser, the files are pulled from your local setup rather than a hosting server.  

This is beneficial when installing WordPress, making changes, collaborating with other developers, and debugging issues before releasing your work. You can either set up this environment manually or use a tool like Bluehost WonderSuite to automate the process and streamline development. 

Join the WordPress community 

One of the biggest strengths of WordPress is its large, active global community. Unlike other content management systems, WordPress has millions of dedicated members working to improve the platform. You can connect with these members via support forums, Slack, WordPress meetups, or in person at WordCamp events and other gatherings worldwide. 

Being part of this community offers numerous benefits. You can get help with troubleshooting issues, stay informed about updates and new releases, and build valuable connections with other developers and users. Engaging with the WordPress community, including attending WordPress meetups, is a great way to grow your development skills and stay connected. 

Create a portfolio 

When applying for any job, showcasing your skills is key, and this is especially important in WordPress development. One of the best ways to “show, not tell” is by building a professional portfolio. A strong portfolio that highlights your personal projects and development process can boost your chances of landing a full-time job or freelance gigs. 

A good professional portfolio might showcase a range of WordPress projects, like custom themes, eCommerce sites, and review sites, allowing you to display your varied work to potential clients or employers. 

That said, a portfolio isn’t always needed, especially if you’ve contributed to open-source projects like the WordPress Core. In back-end development, personal projects or contributions to larger projects can sometimes matter more than a polished portfolio. 

Continuing education and resources
