Create a controller
All controllers extend
Zend_Controller_Action
Naming conventions

 Controllers end with 'Controller':
IndexController, GuestbookController

 Action methods end with 'Action':
signAction(), displayAction(), listAction()

Controllers should be in the
application/controllers/ directory, and named
after the class, with a “.php” suffix:

application/controllers/IndexController.php

– Controller name used is same as it appears on the
url:
• “GuestbookController” appears on the URL as
“guestbook”
• View script name is the action name as it
appears on the url:
• “signAction()” appears on the URL as “sign”

Create a Form

Zend_Form:

• Flexible form generations
• Element validation and filtering

Decorators for labels and HTML wrappers
• Optional Zend_Config configuraion

Create a form – Identify elements
