There is a way to validate without using models, which can also be used for forms, at least in CakePHP2.

For example, I had to validate params and I saw no point in creating models for each action that requires params.

So, I used this:

1. Before the controller class declaration

   App::uses('Validation', 'Utility');

2. In the action with a $code param

   function checkcode($code) { ... Validation::alphaNumeric($code); ... }
