| Code Examples | Component files contain actions or functions that can be used
across all the controllers. A component typically aims to provide
tools to accomplish a main objective.
=> The file name of a component can be anything, but like
models, views, and controllers, more than one word in the
name must be separated by underscores and camel case when
naming the class object.
Including Components in the Controller with the $components Array
var $components = array('Session','RequestHandler');
Running a Component Function in the Controller
$user = $this->Session->read('User');
Components are not intended to work directly with the database, so
the component does not do much more than return a variable, a
string, or an array for the controller to use. |
