Register settings with register_setting and define sections with add_settings_section. Create fields using add_settings_field for individual options. Use settings_fields and do_settings_sections to render forms. Implement custom validation callbacks for complex requirements. Store […]

Implement automated tests to ensure plugin reliability. Unit tests verify individual functions work correctly. Integration tests check how components work together. Use PHPUnit for testing WordPress plugins. Create test fixtures and mocks for dependencies. Test edge cases and error conditions. Continuous testing catches regressions early. Maintain high code coverage for critical functions. Automated tests save […]

WordPress provides the wpdb class for database interactions. Use wpdb prepare for all queries with variables to prevent SQL injection. Methods like get_results, get_row, and get_var retrieve data efficiently. The insert, update, and delete methods simplify common operations. Create custom tables only when necessary, prefixing with wpdb prefix. Handle database errors gracefully using wpdb last_error. […]

Make your plugin translatable from the start using __() and _e() functions with text domains. Define your text domain in plugin headers. Use load_plugin_textdomain() to load translation files. Proper text domain prevents conflicts with other plugins. Create POT files for translators using tools like Poedit. Avoid concatenating translatable strings; always pass complete strings to translation […]

AJAX enhances user experience by enabling dynamic updates without page reloads. WordPress provides built-in AJAX handling through admin-ajax.php. Register AJAX actions using wp_ajax and wp_ajax_nopriv hooks. Use wp_localize_script to pass the AJAX URL and nonce to JavaScript. Always verify nonces in PHP handlers for security. Return data using wp_send_json_success or wp_send_json_error. Handle both authenticated and […]
