Validation of Zend Form using Zend Validate | Open Programming Laboratory

intro

Let’s validate submitted data using Zend Form.You can download the source code of this article from here.

1.Create Controller

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

<?php
require_once 'Zend/Controller/Action.php';
require_once 'Zend/Form.php';

class IndexController extends Zend_Controller_Action
{
    public function getProfileForm()
    {
        $form = new Zend_Form();
        $form->setAction($this->_request->getBaseUrl() . '/index/profile')
             ->setMethod('post');

        $givenName = $form->createElement('text', 'givenName');
        $givenName->setLabel('Given Name')
                  ->setRequired(true)
                  ->addFilter('stringTrim')
                  ->addValidator('stringLength', false, array(1,50));
        $familyName = $form->createElement('text', 'familyName');
        $familyName->setLabel('Family Name')
                   ->setRequired(true)
                   ->addFilter('stringTrim')
                   ->addValidator('stringLength', false, array(1,50));
        $email = $form->createElement('text', 'email');
        $email->setLabel('E-Mail')
              ->setRequired(true)
              ->addFilter('stringTrim')
              ->addValidator('emailAddress', false);
        $url = $form->createElement('text', 'url');
        $url->setLabel('URL')
            ->setRequired(false)
            ->addFilter('stringTrim')
            ->addValidator('stringLength', false, array(1,100));
        $submit = $form->createElement('submit', 'submit');
        $submit->setLabel('Send');

        $form->addElements(array(
            $givenName, $familyName, $email, $url, $submit
        ));

        return $form;
    }

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

    public function profileAction()
    {
        $form = $this->getProfileForm();
        if ($this->getRequest()->isPost()) {
            if ($form->isValid($_POST)) {
                $values = $form->getValues();
                $this->view->values = $values;
            }
        }
        $this->view->form = $form;
    }
}

<?php

require_once 'Zend/Controller/Action.php';

require_once 'Zend/Form.php';

class IndexController extends Zend_Controller_Action

{

public function getProfileForm()

{

$form = new Zend_Form();

$form->setAction($this->_request->getBaseUrl() . '/index/profile')

->setMethod('post');

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

$givenName->setLabel('Given Name')

->setRequired(true)

->addFilter('stringTrim')

->addValidator('stringLength', false, array(1,50));

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

$familyName->setLabel('Family Name')

->setRequired(true)

->addFilter('stringTrim')

->addValidator('stringLength', false, array(1,50));

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

$email->setLabel('E-Mail')

->setRequired(true)

->addFilter('stringTrim')

->addValidator('emailAddress', false);

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

$url->setLabel('URL')

->setRequired(false)

->addFilter('stringTrim')

->addValidator('stringLength', false, array(1,100));

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

$submit->setLabel('Send');

$form->addElements(array(

$givenName, $familyName, $email, $url, $submit

));

return $form;

}

public function indexAction()

{

$this->_forward('profile');

}

public function profileAction()

{

$form = $this->getProfileForm();

if ($this->getRequest()->isPost()) {

if ($form->isValid($_POST)) {

$values = $form->getValues();

$this->view->values = $values;

}

$this->view->form = $form;

}

2.Create View

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Zend Framework Quick Start</title>
  </head>
  <body>
  <h1 id="5_basic-blog_1" ><?= $this->translate('Your Profile'); ?></h1>
    <?php if($this->values) : ?>
    <h3 id="5_submitted" >
      <?= $this->translate('You just submitted the following values'); ?>:
    </h3>
    <ul>
      <?php foreach ($this->values as $value) :?>
      <li>
        <?= $this->escape($value); ?>
      </li>
      <?php endforeach; ?>
    </ul>
    <?php else : ?>
        <?= $this->form; ?>
    <?php endif; ?>
  </body>
</html>
