# WooCommerce Backend Development This skill provides guidance for developing WooCommerce backend PHP code according to project standards and conventions. ## When to Use This Skill **ALWAYS invoke this skill before:** - Writing new PHP unit tests (`*Test.php` files) - Creating new PHP classes - Modifying existing backend PHP code - Adding hooks or filters ## Instructions Follow WooCommerce project conventions when adding or modifying backend PHP code: 1. **Creating new code structures**: See [file-entities.md](file-entities.md) for conventions on creating classes and organizing files (but for new unit test files see [unit-tests.md](unit-tests.md)). 2. **Naming conventions**: See [code-entities.md](code-entities.md) for naming methods, variables, and parameters 3. **Coding style**: See [coding-conventions.md](coding-conventions.md) for general coding standards and best practices 4. **Type annotations**: See [type-annotations.md](type-annotations.md) for PHPStan-aware PHPDoc annotations 5. **Working with hooks**: See [hooks.md](hooks.md) for hook callback conventions and documentation 6. **Dependency injection**: See [dependency-injection.md](dependency-injection.md) for DI container usage 7. **Data integrity**: See [data-integrity.md](data-integrity.md) for ensuring data integrity when performing CRUD operations 8. **Writing tests**: See [unit-tests.md](unit-tests.md) for unit testing conventions ## Key Principles - Always follow WordPress Coding Standards - Use class methods instead of standalone functions - Place new internal classes in `src/Internal/` by default - Use PSR-4 autoloading with `Automattic\WooCommerce` namespace - Write comprehensive unit tests for new functionality - Run linting and tests before committing changes ## Version Information To determine the next WooCommerce version number for `@since` annotations: - Read the `$version` property in `includes/class-woocommerce.php` **on the trunk branch** - Remove the `-dev` suffix if present - Example: If trunk shows `10.4.0-dev`, use `@since 10.4.0` - Note: When reviewing PRs against trunk, the version in trunk is correct even if it seems "future" relative to released versions
