The WordPress and Ajax e-book is a comprehensive view on using Ajax with WordPress. It covers Ajax like you've never seen before.
The book contains three real-life examples that provide the rationale and logic behind coding decisions, the reasons for Ajax's use, and the steps from inception to completion of the examples.
First, the book builds a foundation for you to send your first Ajax request.
This includes:
After the foundation has been built, the book introduces you to sending you first request.

After the foundation has been laid and you have a good idea of the theory behind an Ajax request, we begin work on the examples.
The book contains three real-life examples that provide the rationale and logic behind coding decisions, the reasons for Ajax's use, and the steps from inception to completion of the examples.
First, the book builds a foundation for you to send your first Ajax request.
This includes:
- An explanation of Ajax best practices - What Ajax should do, and what it isn't meant to do.
- How to add scripts and styles properly to WordPress - How plugin and theme authors should add scripts to WordPress. This also covers page detection and other advanced techniques.
- Properly formatting scripts using jQuery - How to adhere to the jQuery authoring guidelines for easy-to-read code and maximum compatibility.
- Localizing your JavaScript files - How to add localized JavaScript variables without using PHP.
- An explanation on how to override someone's scripts and styles.
- WordPress security, including nonces and data validation.
- Several different Ajax techniques are explained.
After the foundation has been built, the book introduces you to sending you first request.
Sending your first request includes learning:
- Learning the code foundation for sending that first request.
- Adding server-side security for the request.
- Processing the request on the server-side.
- Responding to the request on the server-side.
- Parsing the response on the client-side.
- Outputting the data to the user.
After the foundation has been laid and you have a good idea of the theory behind an Ajax request, we begin work on the examples.
- Example 1: WP Grins Lite - We take a common and popular plugin and convert it to use Ajax for the loading of the smilies.
- Example 2: Static Random Posts - We take a common widget and add an Ajax function to it. This example will not only teach you how to create a widget, but also an admin panel, and Ajax functionality.
- Example 3: Ajax Registration Form - We take an ordinary registration form and perform data validation on it using Ajax.
