Add to your

include_path

<?phpset_include_path(implode(PATH_SEPARATOR, array( '.', '/home/matthew/zf/library', get_include_path(),)));

Step 1:Create the project

Using the Model in the ControllerUsing the Model in the ControllerLocate the zf utility

In bin/zf.sh of bin/zf.bat of your ZF install (choose based on your OS)

Place bin/ in your path, or create an alias on your path:

alias zf=/path/to/bin/zf.sh

Create the project

# Unix:% zf.sh create project quickstart

# DOS/Windows:C:> zf.bat create project quickstart

# Unix:% zf.sh create project quickstart

# DOS/Windows:C:> zf.bat create project quickstart

Create a vhost

<VirtualHost *:80> ServerAdmin you@atyour.tld DocumentRoot /abs/path/to/quickstart/public ServerName quickstart

<Directory /abs/path/to/quickstart/public> DirectoryIndex index.php AllowOverride All Order allow,deny Allow from all </Directory></VirtualHost>

Step 2: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.phpapplication/controllers/GuestbookController.php

Create a controller

IndexController.php

Step 3:Create the model

Using the Model in the ControllerUsing the Model in the ControllerUsing the Model in the Controller

• Controller needs to retrieve Model

• To start, let's fetch listings

Using the Model in the ControllerUsing the Model in the ControllerAdding the Model to the Controller

Using the Model in the ControllerUsing the Model in the ControllerTable Module – Access Methods

Step 4:Create views

Create a view scriptCreate a view

• View scripts go in application/views/scripts/

• View script resolution looks for a view script in a subdirectory named after the controller

– 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”

index/index.phtml view script

Step 5:Create a form

Create a Form

Zend_Form:

• Flexible form generations

• Element validation and filtering

• Rendering

View helper to render element

Decorators for labels and HTML wrappers

• Optional Zend_Config configuraion

Create a form – Identify elements

Guestbook form:

• Email address

• Comment

• Captcha to reduce spam entries

• Submit button

Create a form – Guestbook form

Using the Form in the Controller

• Controller needs to fetch form object

• On landing page, display the form

• On POST requests, attempt to validate the form

• On successful submission, redirect

Adding the form to the controllerAdding the form to the controller

Step 6:Create a layout
