The skeleton for an object-oriented/MVC WordPress plugin.
- Clean and organized
- Designed with object-oriented principles
- Implements the Model-View-Controller pattern
- Includes basic classes for:
- Custom post type and taxonomies
- A settings page
- Extra user profile fields
- WP-Cron jobs
- Includes examples of common functionality
- Single and network-wide activation
- Upgrade routine
- Shortcodes
- CSS/JavaScript enqueing
- Input validation, output sanitization
- Custom hooks for extensibility
- JavaScript event handlers
- A test suite for unit testing with SimpleTest
- Includes
render_template(), a wrapper for rendering view files that allows other plugins and themes to easily modify or completely override the view.
- I prefer having controllers and models in the same class/file, so I use an unofficial @mvc tag in the phpDoc comments to mentally keep track of which methods are controllers and which are models.
- If you want to learn more about the principles behind the design of this plugin, I gave a presentation on OOP at WordCamp Seattle 2013, and another on MVC at WordCamp Columbus 2013.
- cd /var/www/vhosts/example.com/content/plugins
- git clone --recursive https://github.com/iandunn/WordPress-Plugin-Skeleton.git plugin-slug
- cd plugin-slug
- git remote rm origin
- git rm README.md
- Update bootstrap.php headers
- Reset version number to 0.1
- Find/replace class names/slugs
- git mv files to match class slugs
- Comment out references to classes that aren't needed now. Delete ones that will never be needed.
- Rename generic comments, method names, etc to describe their specific implementations.
- If you're not using a custom post type or something else that updates the rewrite rules, you can comment out the flush_rewrite_rules() call in WordPresPluginSkeleton::activate() and ::deactivate().
- For unit testing, install SimpleTest for WordPress and use a shortcode like this: [simpletest name="WordPress Plugin Skeleton Unit Test Suite" path="/wordpress-plugin-skeleton/tests/wpps-test-suite.php"]
- Security
- Input validation for domain correctness and security.
- Output sanitization when sending untrusted data to browser.
- All data should be considered untrusted.
- Escape hardcoded data to future-proof.
- Pass any manual SQL queries through $wpdb->prepare().
- Add/check nonces for logged in users when submitting forms and AJAX requests.
- Make sure current user is authorized to perform the action with current_user_can().
- If added any kind of custom auth scheme, try to think how you could get around it, then protect against those methods.
- Add custom actions and filters
- Write unit and integration tests
- Throw/catch exceptions when encountering invalid conditions.
