Magento already provides several useful classes under Mage/Adminhtml/Model/System/Config/Source. Some of the classes we can find are: ° ° YesNo ° ° Country ° ° Currency ° ° AllRegions ° ° Category ° ° Language By just using XML, we can build complex configuration options for our modules right on the Magento backend, without having to worry about setting up templates for populating fields or validating data.

Magento Fundamentals for Developers Magento is also kind enough to provide a comprehensive amount of form field validation models, which we can use with the tag. Among the following field validators we have: • validate-email • validate-length • validate-url • validate-select • validate-password As with any other part of Magento we can extend the source_model, frontend_ type, and validator functions and even create new ones. We will be tackling this task in a later chapter where we will create a new type of each. But for now, we will explore the concepts of models, views, file layouts, and controllers. Models Magento makes use of the ORM approach; although we can still use Zend_Db to access the database directly, we will be using models to access our data most of the time. For this type of task, Magento provides the following two types of models: • Simple models: This model implementations are a simple mapping of one object to one table, meaning our object attributes match each field and our table structure • Entity Attribute Value (EAV) models: This type of models are used to describe entities with a dynamic number of attributes Magento splits the model layer up into two parts: a model handling the business logic and a resource handling the database interaction. This design decision allows Magento to eventually support multiple database platforms without having to change any of the logic inside the models. Magento ORM uses one of PHP's magic class methods to provide dynamic access to object properties. In the next chapter we will look into models, the Magento ORM, and the data collections in more detail. Magento models don't necessarily have to be related to any type of table in the database or an EAV entity. Observers, who we will be reviewing later, are perfect examples of this type of Magento models. [ 42 ] www.it-ebooks.info
