Zend redirect within view helper - php

Question

Hi i have a following script to redirect within view helper
<?php
class Application_View_Helper_ExistUserRev extends Zend_View_Helper_Abstract{
public function existUserRev($params,$user)
{
$businessReviewMapper = new Application_Model_Mapper_BusinessReviewsMapper();
$businessReviewModel = new Application_Model_BusinessReviews();
$result = $businessReviewMapper->userReviewStatus($user>getUserId(),$params['bzid']);
if($result){
$url = 'http://www.akrabat.com';
$this->_helper->redirector->gotoUrl($url);
}
}
}
?>
But it seems that my above redirect seems not working. How can i redirect within view helper of my zend app? Thanks

Answer 1

As you're in a View Helper class, you can't use $this->_helper->redirector->gotoUrl($url);, this is an Action Controller function.
You have to call the redirector in your View Helper.
Try this :
$_redirector = Zend_Controller_Action_HelperBroker::getStaticHelper('redirector');
$_redirector->gotoUrl($url);

Answer 2

Redirector is a controller ACTION helper, not a View helper, so you should use it from the controller, not from the view.
To redirect from the view (not a good idea BTW, the logic should stay in the controller, not in the view), try using the Zend Action View Helper

This is even simpler then presented so far:
Excerpt from Zend Framework 1.x reference: Writing Custom Helpers
In general, the class should not echo or print or otherwise generate
output. Instead, it should return values to be printed or echoed. The
returned values should be escaped appropriately.
Basically a view helper should return a value, not perform an action.
Action helpers on the other hand can do pretty much anything you need done.
Here is a very simple example to demonstrate the form of using the direct() method in the helper:
<?php
/**
* Simply returns a search form to a placeholder view helper
*
*/
class My_Controller_Action_Helper_Search extends Zend_Controller_Action_Helper_Abstract
{
/**
* #param string $action
* #param string $label
* #param string $placeHolder
* #return \Application_Form_Search
*/
public function direct($action, $label = null, $placeHolder = null)
{
$form = new Application_Form_Search();
$form->setAction($action);
$form->search->setLabel($label);
$form->query->setAttribs(array(
'placeholder' => $placeHolder,
'size' => 20,
));
return $form;
}
}
here is how it's used in a controller to populate a placeholder helper in either a view script or a layout.
public function preDispatch()
{
$this->_helper->layout()->search = $this->_helper->search(
'/index/display', 'Search My Collection!', 'Search Query'
);
}
and in the view script or layout:
<?php echo $this->layout()->search?>
In your case you might use an action helper to establish the values needed to construct the proper url, then you could pass those value to the url() helper or to a helper of your own construction.
