Hi,
I made action helper which processes my forms. I give it the form, the row
object and the success redirect url which can be modified with row data.
Pros
-thin controller
-can define redirect url in controller where I have possibility to use other
action helpers like url etc.
-Can also make AJAX functionality
Cons (at least at this point)
-Handles only Zend_Db_Table_Row objects
-AJAX responding is now compatible with my systems, what if it must be
different?
In my controller action (example):
public function editAction()
{
$model = new User_Model_User(); // Note! this is Model, not
DbTable
$form = $model->getForm(); // Gets User_Form_Profile class
$user_row = $model->getUser($this->_getParam("id")); // Get
user row to be
edited
$this->_helper->form->process($form, $user_row, "user/:id");
$this->view->form = $form;
}
My own Action helper:
<?php
class My_Controller_Action_Helper_Form extends
Zend_Controller_Action_Helper_Abstract
{
public function process($form, Zend_Db_Table_Row_Abstract $row,
$redirect_url = "")
{
$request = $this->getRequest();
// If there is a POST
if ($request->isPost())
{
// If posted by AJAX and has errors
if ($request->isXmlHttpRequest() &&
!$form->isValidPartial($request->getPost()))
{
$response["messages"] = $form->getMessages();
$this->getActionController()->getHelper("json")->direct($response);
}
// Normal and AJAX post and no errors
if ($form->isValid($request->getPost()))
{
$row->setFromArray($form->getValues());
$id = $row->save();
}
if ($id > 0)
{
$redirect_url =
$this->_setRedirectUrl($redirect_url, $row);
// If posted by AJAX
if ($request->isXmlHttpRequest())
{
$this->getActionController()->getHelper("json")->direct(array("redirect" =>
$redirect_url));
}
else
{
$this->getActionController()->getHelper("redirector")->gotoUrl($redirect_url);
}
}
}
else // Just populate the form with row data
{
$form->populate($row->toArray());
}
}
protected function _setRedirectUrl($url, Zend_Db_Table_Row_Abstract
$row)
{
foreach ($row->toArray() as $field => $value)
{
$url = str_replace(":{$field}", $value, $url);
}
return $url;
}
}
