Creating Confirmation Screen using Zend_Session

The example to use Zend_Session and create confirmation screen is shown in this article. You can download the source code of this article from here.

Create the file application/bootstrap.php with the following content.

<?php
set_include_path('../library' . PATH_SEPARATOR . get_include_path());
define('APP_BASE', '../application');
define('CONFIG_PATH', APP_BASE . '/config.ini');
 
require_once 'Zend/Controller/Front.php';
require_once 'Zend/Layout.php';
require_once 'Zend/Db.php';
require_once 'Zend/Config/Ini.php';
require_once 'Zend/Db/Table/Abstract.php';
 
$layout = Zend_Layout::startMvc();
//$layout->getView()->baseUrl = '/yourBaseUrl';
 
$config = new Zend_Config_Ini(CONFIG_PATH, 'staging');
$params = $config->database->params->toArray();
$params['options'][Zend_Db::CASE_FOLDING] = Zend_Db::CASE_LOWER;
$dbAdapter = Zend_Db::factory($config->database->adapter, $params);
Zend_Db_Table_Abstract::setDefaultAdapter($dbAdapter);
 
Zend_Controller_Front::run(APP_BASE . '/controllers');

Create the file application/config.ini with the following content.
Please modify database.params.* properly.

[staging]
database.adapter         = pdo_mysql
database.params.host     = localhost
database.params.username = db_user
database.params.password = db_password
database.params.dbname   = db_name

In this article, we will use the following sql.

CREATE TABLE profiles
(
    id integer AUTO_INCREMENT NOT NULL PRIMARY KEY,
    user_id integer         NOT NULL,
    first_name varchar(100) NOT NULL,
    last_name varchar(100)  NOT NULL,
    email varchar(200)      NOT NULL,
    url varchar(200)        NOT NULL
);
 
INSERT INTO profiles (user_id, first_name, last_name, email, url)
    VALUES (1, 'Myfirstname', 'Mylastname', 'my@emailaddress',
        'http://myurl/my/page');

Create the file application/models/Profiles.php with the following content.

<?php
require_once 'Zend/Db/Table/Abstract.php';
require_once 'Zend/Form.php';
 
class Profiles extends Zend_Db_Table_Abstract
{
    protected $_name = 'profiles';
 
    public function getForm()
    {
        $form = new Zend_Form();
 
        $first_name = $form->createElement('text', 'first_name');
        $first_name->setLabel('First Name')
                   ->setRequired(true)
                   ->addFilter('stringTrim')
                   ->addValidator('stringLength', false, array(1,100));
        $last_name = $form->createElement('text', 'last_name');
        $last_name->setLabel('Last Name')
                   ->setRequired(true)
                   ->addFilter('stringTrim')
                   ->addValidator('stringLength', false, array(1,100));
        $email = $form->createElement('text', 'email');
        $email->setLabel('E-Mail')
              ->setRequired(true)
              ->addFilter('stringTrim')
              ->addValidator('emailAddress', false)
            ->addValidator('stringLength', false, array(1,200));
        $url = $form->createElement('text', 'url');
        $url->setLabel('URL')
            ->setRequired(false)
            ->addFilter('stringTrim')
            ->addValidator('stringLength', false, array(1,200));
 
        $form->addElements(array(
            $first_name, $last_name, $email, $url
        ));
 
        return $form;
    }
 
    public function findByUserId($user_id)
    {
        $select = $this->select()->where('user_id = ?', $user_id);
        return $this->fetchAll($select);
    }
}

Create the file application/constorllers/IndexController.php with the following content.

<?php
require_once 'Zend/Controller/Action.php';
require_once 'Zend/Session/Namespace.php';
require_once APP_BASE . '/models/Profiles.php';
 
class IndexController extends Zend_Controller_Action
{
    protected $_user_id = 1;
 
    protected function prepareForm($form, $label, $back)
    {
        $form->setAction($this->_request->getBaseUrl() . '/index/index')
             ->setMethod('post');
        $submit = $form->createElement('submit', $label);
        $submit->setLabel($label);
        $form->addElement($submit);
 
        if ($back)
        {
            $back = $form->createElement('submit', 'back');
            $back->setLabel('Back');
            $form->addElement($back);
        }
 
        return $form;
    }
 
    public function indexAction()
    {
        // get default form values
        $session = new Zend_Session_Namespace('index');
        $profiles = new Profiles();
 
        $form = $profiles->getForm();
        $label = 'confirm';
        $back = false;
        if ($this->getRequest()->isPost())
        {
            if (isset($_POST['confirm']))
            {
                if ($form->isValid($_POST))
                {
                    // confirm
                    $session->values = $form->getValues();
                    $this->view->profile = $form->getValues();
                    $form = new Zend_Form();
                    $label = 'save';
                    $back = true;
                }
            }
            else if (isset($_POST['save']))

                if (!$row)
                {
                    $row = $profiles->createRow(array('user_id' => $this->_user_id));
                }
                $values = $session->values;
                $session->values = null;
                $row->setFromArray($values);
                $row->save();
                return $this->render('finish');
            }
            else if (isset($_POST['back']))
            {
                // restore values
                if (isset($session->values))
                {
                    $form->setDefaults($session->values);
                    $session->values = null;
                }
            }

                $values = $session->values;
            }
            else if ($row)
            {

        }
 
        $this->view->form = $this->prepareForm($form, $label, $back);
    }
}

Create the file application/views/scripts/index/index.phtml with the following content.

 
<h1><?= $this->translate('Your Profile') ?></h1>
 
<?php if ($this->profile) : ?>
<dl>
<?php foreach($this->profile as $key => $value) : ?>
<dt><?= $this->translate($key) ?></dt>
<dd><?= $this->escape($value) ?></dd>
 
<?php endforeach; ?>
</dl>
 
<?php endif; ?>
<?= $this->form ?>

Create the file application/views/scripts/index/finish.phtml with the following content.

 
<h1><?=$this->translate('Profile Edited')?>
<h1>
<a href="<?= $this->baseUrl?>/index/index"><?= $this->translate('Back') ?></a>

Access the web server and check the screen flow.

I will extend this controller.
