Professional WordPress Plugin Development, 2nd Edition

Me ha servido de mucho, muy bien explicado y con ejemplos claros

This is a great book by guys who know what they are talking about. It is NOT an introduction to programming - you need to have some programming skills before going in. But it is exactly what a programmer who is considering developing plugins for WordPress needs. Highly recommended.

Anyone can write a plugin. In fact, there's an entire guide/developer handbook dedicated to helping anyone create their first plugin. What that said, it's not as easy as it sounds. Just write a plugin and poof, problem solved. Where do you start? What are best practices? You're going to have a lot of questions. This is the book with most, if not all, the answers.

Good book with salient information, nothing extraneous and just what you need to get writing WP plugin's - very happy. Recommend to other programmers.

Amazing book. Does a pretty decent job of explaining WordPress in its entirety.
