When a book takes four pages to describe how to download a .zip file from a website, you know you're in for what might amount to being a tedious read.
Between the terrible grammar, typos in the code examples and standard text, needless repetition ("The Auth component is a built-in component of CakePHP that makes it very easy to authenticate users in a CakePHP application"), bad typesetting (probably to achieve a certain page-count) and parts of the text that simply make you wonder just what are the authors are trying to say you'd be forgiven for wondering if the book had any professional editors at all.
For example: "In Cake, all controllers are subclasses of the AppController class." - fair enough. But, then... "Methods defined inside the AppController class that can be called from different controllers."
'minLength' is continuously spelled incorrectly as 'minLenght' - there are other goofs too. There's no progressive use of Javascript/AJAX in the demonstrations - if a user has Javascript turned off there's no backend/alternative support. This is something that at least one of the technical editors should have caught.
If you're looking for a book to give you an in-depth introduction to CakePHP, you shouldn't buy this one.
Although the book refers to CakePHP 1.2 which is by now outdated by the 1.3 version, it is good enough to get you started right away and teach you all the concepts that a novice CakePHP programmer needs
My only wish is that the examples were a little more interesting and that the book covered more advaced topics.
