The Bakery has four new articles/tutorials they've posted lately looking at things like thumbnail generation, data validation and add/delete behavior.

• Thumbnails generation with phpThumb - phpThumb is a great thumbnail generator, it can generate thumbs with GD, GD2 or ImageMagick. There are many features like crop, rotate, watermark,... see all the features on the phpThumb homepage.
• HABTM Add & Delete Behavior - Many people gripe about the HABTM associations in CakePHP and how difficult it is to add or delete a single record. This behavior takes care of the task for you!
• Flexible controller and modelpaths - This short tutorial will show you how to organize your model and controller in subfolders of the controllers and models folders!
• Rails-like Data Validation - Validate your data like in rails: http://rails.rubyonrails.com/classes/ActiveRecord/Validations/ClassMethods.html

There's more great content where these came from, so be sure to check out the rest of The Bakery for more great tips.
