What to Know

What are the key code areas involved in developing a new plugin?

The following code features form the backbone of developing a robust WordPress plugin, keeping in mind WordPress's ecosystem, security, performance, and user experience:

Plugin Header:
Every plugin starts with a header in the main PHP file that includes plugin name, description, version, author, and other metadata.

PHP Functions:
Use PHP for all backend logic, including hooks, filters, and custom functions. Functions are crucial for adding new features or modifying existing WordPress behaviors.

Hooks:
Utilize WordPress action and filter hooks to execute code at specific points in WordPress. Actions for doing things, filters for modifying data.

Shortcodes:
Create shortcodes for easily adding custom functionality or content to posts, pages, or widgets via short, memorable codes.

Widgets:
Develop custom widgets to extend the WordPress admin and frontend by adding new sidebar or dashboard elements.

Custom Post Types:
Register new types of content beyond posts and pages to manage different data forms within WordPress.

Options and Settings:
Implement settings pages using the WordPress Settings API to allow users to configure your plugin.

Enqueue Scripts and Styles:
Properly add JavaScript and CSS files to your plugin without conflicting with other scripts or styles on the site.

Database Operations:
Interact with WordPress database using functions like get_option(), update_option(), or even custom queries, but always through WordPress's database abstraction layer.

Security:
Follow WordPress coding standards for security, like sanitizing inputs and escaping outputs, using nonces for form submissions, and validating user capabilities.

Internationalization:
Make your plugin translatable by using functions like __() for translating strings, allowing the plugin to be used in different languages.

Activation and Deactivation:
Include functions to handle what happens when your plugin is activated or deactivated, like adding or removing options from the database.

Uninstall:
Optionally, include an uninstall method to clean up after your plugin when it's deleted, removing options, custom tables, or other data.

Documentation:
Write inline documentation using PHPDoc comments for functions, classes, and methods to make your code more maintainable and understandable.

Version Control:
Keep track of changes using version control systems like Git, even if not hosting on platforms like GitHub or GitLab.

Compatibility:
Ensure your plugin works with different versions of WordPress by testing and using version checks (if ( version_compare( $wp_version, '4.7', '<' ) )).

Error Handling and Logging:
Implement error logging (error_log()) or use WordPress's debugging tools to help diagnose issues.

AJAX Calls:
If needed, set up AJAX handlers for dynamic content loading or user interactions without page reloads.

REST API:
Extend or use the WordPress REST API for modern web applications, allowing interaction with your plugin's data via HTTP requests.

User Roles and Capabilities:
Manage permissions by checking user roles or adding custom capabilities to control who can use features of your plugin.

Performance Considerations:
Optimize code to not slow down WordPress, using techniques like lazy loading, caching, or efficient database queries.

Testing:
While not strictly code, the development process should include unit and integration tests to catch bugs early.
