Last month, I covered Five Cardinal Sins of WordPress Development. Obviously, there are more (and the comments provided a great example of additional thoughts), but there are also a number of practices that we should all be striving for, as well.
On Envato, I cover a number of best practices for WordPress development.
In the article, I hit on the following points:
- Following programming guidelines
- Document your code
- Use the WordPress unit test
- Debug, Log, Review, Repeat
- Avoid deprecated functions
