zend 建立form

參考：Create A Form
跟使用者互動就透過form啦
1.建立form
指令：% zf create form Guestbook
Creating a form at application/forms/Guestbook.php
Updating project profile '.zfproject.xml'


// 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
應該會出現下圖
