Pass a form with post method to another controller - zend-framework

Question

I have a simple Zend Form that contains a textbox with setRequired(TRUE) and other validators and a simple submit button in IndexController.
My question is, is it possible another controller will process and validate my post form?
Login.php
<?php
class Application_Form_Login extends Zend_Form
{
public function init()
{
$username = $this->createElement('text', 'username');
$username->setLabel('Username:');
$username->setRequired(TRUE);
$username->addValidator(new Zend_Validate_StringLength(array('min' => 3, 'max' => 10)));
$username->addFilters(array(
new Zend_Filter_StringTrim(),
new Zend_Filter_StringToLower()
)
);
$this->addElement($username);
// create submit button
$this->addElement('submit', 'login',
array('required' => false,
'ignore' => true,
'label' => 'Login'));
}}
IndexController.php
<?php
class AttendantController extends Zend_Controller_Action
{
public function indexAction()
{
$loginForm = new Application_Form_Login();
$loginForm->setAction('/Auth/process');
$loginForm->setMethod('post');
$this->view->loginForm = $loginForm;
}
}
AuthController.php
class AuthController extends Zend_Controller_Action
{
public function processAction()
{
// How to validate the form posted here in this action function?
// I have this simple code but I'm stacked here validating the form
// Get the request
$request = $this->getRequest();
// Create a login form
$loginForm = new Application_Form_Login();
// Checks the request if it is a POST action
if($request->isPost()) {
$loginForm->populate($request->getPost());
// This is where I don't know how validate the posted form
if($loginForm->isValid($_POST)) {
// codes here
}
}
}
}

Answer 1

You're pretty close. In the process action you create a new instance of the login form (which you are doing), and you pass the POST data to the isValid() method of that form in order to validate. So:
public function processAction()
{
$request = $this->getRequest();
$loginForm = new Application_Form_Login();
if($request->isPost()) {
if($loginForm->isValid($request->getPost)) {
// codes here
} else {
// assign the login form back to the view so errors can be displayed
$this->view->loginForm = $loginForm;
}
}
}
Generally it is easier to display and process the form within the same action, and redirect when the submission is successful. This is the Post/Redirect/Get pattern - see http://en.wikipedia.org/wiki/Post/Redirect/Get. This saves you having to create an instance of the same form in two different actions and makes it easier to redisplay the form in case of errors.

Are you using ' ?
change $loginForm->setAction(/Auth/process); to $loginForm->setAction('/auth/process');
from processAction you may remove $login->populate($request->getPost());
