Creating and Maintaining WordPress Plugins
7 likes7,247 views
The document discusses best practices for creating and maintaining WordPress plugins. It recommends using classes to organize plugin code, hooking into WordPress actions and filters through class methods, storing plugin options in an array, and releasing plugins on WordPress.org for easy community support, professional credibility, and code reuse. Sanity and good coding practices like limiting options and slowing feature additions are also advised.
