Zend Framework 1.X

• Zend Framework is an open source, object oriented
web application framework for PHP 5. Zend
Framework is often called a 'component library',
because it has many loosely coupled components
that you can use more or less independently.

It's mobile browser
allows users to find
various items based
upon augmented
reality technology.

Create Project


Config Apps
/application/configs/application.ini


Bootstrap
/application/Bootstrap.php
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initDoctype()
    {
        $this>bootstrap('view');
        $view = $this>getResource('view');
        $view>doctype('HTML5');
    }
    .......
}


Layouts
• $ zf enable layout
• /application/configs/application.ini
– resources.layout.layoutPath = APPLICATION_PATH
"/layouts/scripts/"
• Twitter Bootstrap http://twitter.github.com/bootstrap/

Other Layouts
$this>_helper>layout>setLayout('layout_other');


ZF overview

• Models(db-
tables,objectmodels)
• Views(helpers,scripts,layouts)
• Controllers(actions,helpers)
• Forms


Namespace & Route

• All classes named for their folder
(e.g.Application_Model_Post in
application/models/post.php)
• Every Zend module is auto loaded when
needed
• Default controller/action is Index
• URLformat: /<controller>/<action>


Controller & Actions
$ zf create controller Point
$ zf create action view Point
$ zf create action add Point
$ zf create action update Point
$ zf create action delete Point
create file /application/controllers/PointController.php
class PointController extends Zend_Controller_Action
{
    public function init()
    {
        /* Initialize action controller here */
    }
    public function indexAction()
   {
       // action body
   }

Views e Actions

• Create views
/application/views/scripts/point/[action].phtml
esempio:
<br /><br />
<div id="viewcontent">
<p>View script for controller <b>Point</b> and
script/action name <b>add</b></p>
</div>


Database

/application/configs/application.ini
PostgreSQL DB
resources.db.adapter = PDO_PGSQL
resources.db.params.host = localhost
resources.db.params.username = postgres
resources.db.params.password =
resources.db.params.dbname = wade


Zend_Db
The Zend_Db_Table solution is an implementation of the
Table Data Gateway pattern. The solution also includes a
class that implements the Row Data Gateway pattern.


DbTable - DbTableRow
$ zf create dbtable Points points
$ zf create model Point

/application/models/Point.php
class Application_Model_Point extends Zend_Db_Table_Row_Abstract
{
    function __get($key)
    {
        if (method_exists($this, $key)) {
            return $this>$key();
        }
        return parent::__get($key);
    }
}


Form - Validation
$ zf create form Point

/application/forms/Point.php
class Application_Form_Point extends Zend_Form
{
    public function init()
    {
        $title = new Zend_Form_Element_Text('title');
        $title>setLabel('title')
                >setRequired(true)
                >addFilter('StripTags')
                >addFilter('StringTrim')
                >addValidator('NotEmpty');
    }
}

Controller – Form
/application/controllers/PointController.php
        $form = new Application_Form_Point();
        $form>submit>setLabel('Add');
        $this>view>form = $form;
        if ($this>getRequest()>isPost()) {
            $formData = $this>getRequest()>getPost();
            if ($form>isValid($formData)) {
                $title = $form>getValue('title');
                ....
                $point = new Application_Model_DbTable_Points();
                $point>addPoint($title, $footnote, $description, $lat, $lon,
$alt);
                $this>_helper>redirector('index');
            } else {
                $form>populate($formData);
            }
        }

Views - Form
/application/views/scripts/point/add.phtml
<?php
$this>title = "Add new Point";
$this>headTitle($this>title);
echo $this>form ;
?>


Models and Table
Relationships
class Application_Model_DbTable_Points extends Zend_Db_Table_Abstract
{
    protected $_dependentTables = array('Application_Model_DbTable_Actions');
....

class Application_Model_DbTable_Actions extends Zend_Db_Table_Abstract
{
    protected $_name = 'actions';
    protected $_rowClass = 'Application_Model_Action';
    protected $_primary = 'id';

    protected $_referenceMap = array(
        'Application_Model_DbTable_Points' => array(
         'columns' => array('point_id'),
            'refTableClass' => 'Application_Model_DbTable_Points',
            'refColumns' => array('id')
        ),
