跟使用者互動就透過form啦
1.建立form

// application/forms/Guestbook.php
class Application_Form_Guestbook extends Zend_Form
{
public function init()
{
// Set the method for the display form to POST
$this->setMethod('post');
// Add an email element
$this->addElement('text', 'email', array(
'label' => 'Your email address:',
'required' => true,
'filters' => array('StringTrim'),
'validators' => array(
'EmailAddress',
)
));
// Add the comment element
$this->addElement('textarea', 'comment', array(
'label' => 'Please Comment:',
'required' => true,
'validators' => array(
array('validator' => 'StringLength', 'options' => array(0, 20))
)
));
// Add a captcha
$this->addElement('captcha', 'captcha', array(
'label' => 'Please enter the 5 letters displayed below:',
'required' => true,
'captcha' => array(
'captcha' => 'Figlet',
'wordLen' => 5,
'timeout' => 300
)
));
// Add the submit button
$this->addElement('submit', 'submit', array(
'ignore' => true,
'label' => 'Sign Guestbook',
));
// And finally add some CSRF protection
$this->addElement('hash', 'csrf', array(
'ignore' => true,
));
}
}
2.建立對應action
指令:% zf create action sign Guestbook
Creating an action named sign inside controller
at application/controllers/GuestbookController.php
Updating project profile '.zfproject.xml'
Creating a view script for the sign action method
at application/views/scripts/guestbook/sign.phtml
Updating project profile '.zfproject.xml'
// application/controllers/GuestbookController.php
class GuestbookController extends Zend_Controller_Action
{
// snipping indexAction()...
public function signAction()
{
$request = $this->getRequest();
$form = new Application_Form_Guestbook();
if ($this->getRequest()->isPost()) {
if ($form->isValid($request->getPost())) {
$comment = new Application_Model_Guestbook($form->getValues());
$mapper = new Application_Model_GuestbookMapper();
$mapper->save($comment);
return $this->_helper->redirector('index');
}
}
$this->view->form = $form;
}
}
3.設定view
<!-- application/views/scripts/guestbook/sign.phtml -->
Please use the form below to sign our guestbook!
<?php
$this->form->setAction($this->url());
echo $this->form;
完成啦,檢查一下http://localhost/guestbook/sign
