WordPress Plug-in Development (Beginner's Guide) focuses on teaching you all aspects of modern WordPress development. The book uses real and published WordPress plug-ins and follows their creation from the idea to the finishing touches, in a series of carefully picked, easy-to-follow tutorials.

In Chapters 2 to 7 you will develop six concrete plug-ins and conquer all aspects of WordPress development. Each new chapter and each new plug-in introduces different features of WordPress and how to put them to good use, allowing you to gradually advance your knowledge.
