请在 /var/www/html/zend1app/application/controllers/CountryController.php 中查看我的编辑功能:
public function editAction() {
$data = $this->getRequest()->getParams();
$id = (int)$data['id'];
$options = array();
$country = $this->getCountryModel()->fetchRow("id=$id");
if(!$country)
{
throw new Exception("Invalid Request Id!");
}
$form = new Application_Form_Country();
$form->addIdElement();
if ($this->getRequest()->isPost()) {
if ($form->isValid($this->getRequest()->getPost())){
$data = new Application_Model_Country();
if($data->save($form->getValues()))
{
$message = array("sucess" => "Country has been updated!");
}
else {
$message = array("danger" => "Country could not be updated!");
}
$this->_helper->FlashMessenger->addMessage($message);
return $this->_helper->redirector('index');
}
}
$options = array (
'id' => $country->id,
'name' => $country->name,
'code' => $country->code
);
$form->populate( $options ); // data binding in the edit form
$this->view->form = $form;
}
和 /var/www/html/zend1app/application/forms/Country.php 的表单类:
class Application_Form_Country 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', 'name', array(
'label' => 'Enter Country Name:',
'required' => true,
'filters' => array('StringTrim'),
'validators' => array(
array('validator' => 'StringLength', 'options' => array(0, 20))
)
));
// Add the comment element
$this->addElement('text', 'code', array(
'label' => 'Enter Country Code:',
'required' => true,
'validators' => array(
array('validator' => 'StringLength', 'options' => array(0, 20))
)
));
// Add the submit button
$this->addElement('submit', 'submit', array(
'ignore' => true,
'label' => 'Save',
));
// And finally add some CSRF protection
$this->addElement('hash', 'csrf', array(
'ignore' => true,
));
}
public function addIdElement()
{
$this->addElement('hidden', 'id');
}
}
