Este libro es exactamente lo que estaba buscando desde que decidi utilizar CodeIgniter como framework php, te lleva paso a paso a como crear una aplicacion con CI y principalmente esa parte privada de toda aplicacion web.
Lo Recomiendo 100% para todo el que este iniciandose en el mundo del MVC con CodeIgniter.

CodeIgniter is the fastest PHP framework out there, and it works. There are very few bugs in the code. The other thing that CodeIgniter has that other frameworks don't is a good forum and excellent documentation. It has an outstanding Users Guide you can download which lists every function with a code example.

And now, there are two books out on CodeIgniter. I purchased both books, and reviewed "CodeIgniter for Rapid PHP Application Development." "Professional CodeIgniter" is a completely different book. I figure folks might want to know the difference before they buy.

"Professional CodeIgniter" walks you through a complete web application from start to finish. The author is an experienced web developer. It is thorough and very detailed. The first chapter introduces you to how to use the MVC architecture with CodeIgniter. The second chapter introduces you to using the Agile development methodologies with a client who needs an ecommerce site. You are inside the head of a web developer as he talks with the client, and draws up what the site will look like on a piece of paper. Then the fun begins. In Chapter 3 you download CodeIgniter and he walks you through laying out the folders and intial configuration of CodeIgniter followed by the initial screen for the site. Other chapters follow:
Chapter 4 - Creating the main web site
Chapter 5 - Building a shopping cart
Chapter 6 - Creating a Dashboard
Chapter 7 - Improving the Dashboard
Chapter 8 - Last Minute Upgrades
Chapter 9 - Security and Performance
Chapter 10 - Launch

The index is very detailed which makes the book good for a reference. There is lots of code and the code is available on the publishers site.

There are some pitfalls. If your going to get anything out of the book you got to follow along, and create the site for yourself, which makes the going slow. On top of that there are bugs in the code which makes the book frustrating, and slows you down further. You can look at it two ways, there are bugs in the code, so this book is a waste; or you're learning how to fix bugs in CodeIgniter. There are times when I was banging my head against the wall. On the other hand, there are things like how to write a search engine and shopping cart for the site that make the book worthwhile. Four stars, a very slow, but thorough read.
A lot of content, but you've got to dig to get the gold.
