Zend_Formによる複数ページフォームの使用例

intro

前回作成した複数ページフォームを使用して実際に画面を作成します。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。
環境に合わせてyourBaseUrlを適切に設定してください。

<?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 users
(
    id integer auto_increment NOT NULL PRIMARY KEY,
    username varchar(20) NOT NULL,
    password varchar(20) NOT NULL
);

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
);

CREATE TABLE users

(

id integer auto_increment NOT NULL PRIMARY KEY,

username varchar(20) NOT NULL,

password varchar(20) NOT NULL

);

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

);

2.モデルの作成

以下のようにapplication/models/Users.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 Users extends Zend_Db_Table_Abstract
{
    protected $_name = 'users';
    protected $_dependentTables = array('Profiles');

    static public function getForm()
    {
        $form = new Zend_Form();

        $username = $form->createElement('text', 'username');
        $username->setLabel('Account Name')
                 ->setRequired(true)
                 ->addFilter('stringTrim')
                 ->addValidator('stringLength', false, array(1,20));
        $password = $form->createElement('password', 'password');
        $password->setLabel('Password')
                  ->setRequired(true)
                  ->addFilter('stringTrim')
                  ->addValidator('stringLength', false, array(1,20));

        $form->addElements(array(
            $username, $password
        ));

        return $form;
    }
}

<?php

require_once 'Zend/Db/Table/Abstract.php';

require_once 'Zend/Form.php';

class Users extends Zend_Db_Table_Abstract

{

protected $_name = 'users';

protected $_dependentTables = array('Profiles');

static public function getForm()

{

$form = new Zend_Form();

$username = $form->createElement('text', 'username');

$username->setLabel('Account Name')

->setRequired(true)

->addFilter('stringTrim')

->addValidator('stringLength', false, array(1,20));

$password = $form->createElement('password', 'password');

$password->setLabel('Password')

->setRequired(true)

->addFilter('stringTrim')

->addValidator('stringLength', false, array(1,20));

$form->addElements(array(

$username, $password

));

return $form;

}

次に以下のように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';
    protected $_referenceMap = array(
        'Account' => array(
            'columns'           => 'user_id',
            'refTableClass'     => 'Users',
            'refColumns'        => 'id'
        )
    );

    static 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;
    }
}

static 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')

$url = $form->createElement('text', 'url');

$url->setLabel('URL')

->setRequired(false)

->addValidator('stringLength', false, array(1,200));

$form->addElements(array(

$first_name, $last_name, $email, $url

));

return $form;

}

3.コントローラの作成

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

<?php
require_once 'Zend/Controller/Action.php';
require_once APP_BASE . '/models/Users.php';
require_once APP_BASE . '/models/Profiles.php';
require_once 'My/Form/MultiPage.php';

class IndexController extends Zend_Controller_Action
{
    protected $_user_id = 1;

    public function preDispatch()
    {
        $this->view->baseUrl = $this->_request->getBaseUrl();
    }

    public function getForm()
    {
        $form = new My_Form_MultiPage('UserProfileForm');
        $form->addForm('Users', Users::getForm());
        $form->addForm('Profiles', Profiles::getForm());
        return $form;
    }

    public function indexAction()
    {
        $this->_forward('list');
    }

    public function listAction()
    {
        $users = new Users();
        $userlist = $users->fetchAll();
        $this->view->userlist = $userlist;
    }

    public function viewAction()
    {
        $users = new Users();
        if (isset($_GET['id']) && intval($_GET['id']))
        {
            $user = $users->find(intval($_GET['id']))->current();
            if ($user)
            {
                $profile = $user->findProfiles()->current();
                if ($profile)
                {
                    $this->view->profile = $profile->toArray();
                }
                $this->view->user = $user->toArray();
            }
        }
    }

    public function addAction()
    {
        $action = $this->_request->getBaseUrl() . '/index/add';
        $form = $this->getForm();
        if ($this->getRequest()->isPost())
        {
            if (isset($_POST['next']) && $form->isValid($_POST))
            {
                if ($form->isConfirm())
                {
                    // confirm values
                    $values = $form->getValues();
                    $this->view->user    = $values['Users'];
                    $this->view->profile = $values['Profiles'];
                    $this->view->form = $form->prepareForm($action, 'add');
                    return $this->render('confirm');
                }
            }
            else if (isset($_POST['add']))
            {
                // save & finish
                $values = $form->getValues();
                $userValues = $values['Users'];
                $profileValues = $values['Profiles'];
                $form->clear();

                $users = new Users();
                $user = $users->createRow($userValues);
                $user_id = $user->save();

                $profiles = new Profiles();
                $profileValues['user_id'] = $user_id;
                $profile = $profiles->createRow($profileValues);
                $profile->save();
                return $this->render('finish');
            }
            else if (isset($_POST['back']))
            {
                $form->back();
            }
            else if (isset($_POST['cancel']))

            }
        }
        $this->view->form = $form->prepareForm($action, 'next');
        $this->view->title = $form->getCurrentFormName();
    }
