cakephp Form

The FormHelper is a new addition to CakePHP. Most of the heavy lifting in form creation is now done using this new class, rather than (now deprecated) methods in the HtmlHelper. The FormHelper focuses on creating forms quickly, in a way that will streamline validation, re-population and layout. The FormHelper is also flexible - it will do almost everything for you automagically, or you can use specific methods to get only what you need.
