Zend Sessionを用いた確認画面の作成

intro

Zend_Sessionを利用して入力した内容を確認する画面を作成します。ソースコードはこちらからダウンロードできます。

1.bootstrap.phpとconfig.iniの作成

以下のようにapplication/bootstrap.phpファイルを作成します。

<?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');

<?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');

以下のようにapplication/config.iniファイルを作成します。
環境に合わせてdatabase.params以下を変更してください。

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

[staging]

database.adapter = pdo_mysql

database.params.host = localhost

database.params.username = db_user

database.params.password = db_password

database.params.dbname = db_name

この記事では以下のSQLを使用しました(MySQL)。

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 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');

2.モデルの作成

以下のようにapplication/models/Profiles.phpファイルを作成します。

<?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);
    }
}

$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);

}

3.コントローラの作成

以下のようにapplication/constorllers/IndexController.phpファイルを作成します。

<?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']))
            {
                // save profile
                $row =$profiles->findByUserId($this->_user_id)->current();
                if (!$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;
                }
            }
        }
        else
        {
            // set default values
            $values = array();
            $row =$profiles->findByUserId($this->_user_id)->current();
            if (isset($session->values))
            {
                $values = $session->values;
            }
            else if ($row)
            {
                $values = $row->toArray();
            }
            $form->setDefaults($values);
        }

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

}

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

}

4.ビューの作成

以下のようにapplication/views/scripts/index/index.phtmlファイルを作成します。

<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 ?>

<?php foreach($this->profile as $key => $value) : ?>

<dt><?= $this->translate($key) ?></dt>

<dd><?= $this->escape($value) ?></dd>

<?php endforeach; ?>

</dl>

<?php endif; ?>

<?= $this->form ?>

以下のようにapplication/views/scripts/index/finish.phtmlファイルを作成します。

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

1 2	<h1><?=$this->translate('Profile Edited')?><h1> <a href="<?= $this->baseUrl?>/index/index"><?= $this->translate('Back') ?></a>

5.確認

Webサーバにアクセスして画面遷移の動作を確認してみてください。
