Overview
Building a WordPress plugin means identifying a specific need, writing compact, secure code, and packaging it so WordPress can load it easily. Start small, iterate, and test in a development environment until you have a reliable, maintainable plugin.
Step-by-step guide
- Plan the feature: define the problem, required user interface, and data flow.
- Scaffold files: create a plugin folder and a main PHP file with the correct plugin header comment so WordPress recognizes it.
- Use hooks and APIs: attach actions and filters, register shortcodes or REST endpoints, and use the Settings API or custom post types as needed.
- Enqueue assets correctly: add scripts and styles with the appropriate wp_enqueue functions and only load them where necessary.
- Secure your plugin: sanitize and validate input, use nonces and capability checks, and escape all output.
- Internationalize and document: wrap strings for translation, add a README, and write inline comments for maintainability.
- Test and deploy: test on multiple PHP and WP versions, use version control, and package the plugin as a zip for distribution or submit to a repository.
