A First-Time Developer’s Guide for Contributing to WordPress

WordPress, powering over 40% of all websites, is an open-source project that thrives on community contributions. As a first-time developer, contributing to WordPress can seem daunting, but it’s an excellent way to improve your skills, give back to the community, and potentially make a lasting impact on millions of websites. This guide will walk you through the process of contributing to WordPress, from setting up your development environment to submitting your first patch.

Why Contribute to WordPress?

Before we dive into the how-to, let’s explore why contributing to WordPress is beneficial:

1. Skill Enhancement: Work on real-world problems and learn from experienced developers.
2. Community Recognition: Build your reputation in the WordPress community.
3. Career Opportunities: Many companies value WordPress contributors when hiring.
4. Personal Satisfaction: Help improve a platform used by millions worldwide.

Now, let’s get started with your journey to becoming a WordPress contributor.

Step 1: Set Up Your Development Environment

To contribute effectively, you need a proper local development environment:

1. Install Local by Flywheel or XAMPP to run WordPress locally.
2. Set up version control with Git.
3. Create a GitHub account if you don’t have one already.

Pro Tip: Familiarize yourself with command-line operations, as you’ll be using them frequently.

Step 2: Understand the WordPress Core Structure

Before making changes, it’s crucial to understand how WordPress is structured:

• wp-admin: Administration area files
• wp-content: Themes, plugins, and uploads
• wp-includes: Core WordPress files

Spend some time exploring these directories to get a feel for the codebase.

Step 3: Choose Your Contribution Area

WordPress offers various ways to contribute:

1. Core: The main WordPress software
2. Themes: The official theme directory
3. Plugins: The official plugin repository
4. Documentation: WordPress Codex and developer resources
5. Support: WordPress.org forums
6. Translations: Internationalization efforts

For this guide, we’ll focus on contributing to WordPress Core.

Step 4: Find an Issue to Work On

1. Visit the WordPress Trac (core.trac.wordpress.org).
2. Look for tickets labeled “good-first-bugs” or “needs-patch”.
3. Read through the ticket to understand the issue and proposed solution.

Pro Tip: Start with small, manageable issues to build confidence and familiarity with the process.

Step 5: Set Up the WordPress Core Development Environment

1. Fork the WordPress Core repository on GitHub.
2. Clone your fork to your local machine:

   git clone https://github.com/your-username/wordpress-develop.git

3. Set up the build process:

   npm install
   npm run build

Step 6: Create a Branch for Your Changes

Always work on a new branch for each contribution:

git checkout -b fix/issue-number-brief-description

Replace “issue-number-brief-description” with appropriate details.

Step 7: Make Your Changes

1. Locate the relevant files for the issue you’re working on.
2. Make the necessary code changes.
3. Follow the WordPress Coding Standards:

• Use tabs for indentation
• Follow naming conventions (e.g., function_name, ClassName)
• Add clear, concise comments

Pro Tip: Use PHP_CodeSniffer with the WordPress Coding Standards to check your code automatically.

Step 8: Test Your Changes

Thorough testing is crucial:

1. Run unit tests:

   npm run test:php

2. For JavaScript changes, run:

   npm run test:js

3. Manually test your changes in different scenarios.

Step 9: Create a Patch

WordPress Core still uses patches for contributions:

1. Generate a patch file:

   git diff > 12345.diff

(Replace 12345 with the actual ticket number)

2. If you’ve added new files, create a patch for those:

   git add .
   git diff --staged > 12345.new.diff

Step 10: Submit Your Patch

1. Log in to WordPress Trac.
2. Navigate to the ticket you’re working on.
3. Add a comment describing your changes.
4. Attach your patch file(s) to the ticket.

Pro Tip: Be patient and open to feedback. Core contributors may suggest changes or improvements.

Step 11: Respond to Feedback

1. Review any comments on your patch.
2. Make necessary adjustments based on feedback.
3. Generate and submit a new patch if needed.

Step 12: Celebrate and Continue Contributing

Once your patch is accepted and committed, congratulations! You’ve made your first contribution to WordPress. Keep the momentum going by finding more issues to work on.
