I have a layout loader plugin which looks like this:
class Controller_Action_Helper_LayoutLoader extends Zend_Controller_Action_Helper_Abstract
{
public function preDispatch()
{
$config = Zend_Registry::get("config");
$module = $this->getRequest()->getModuleName();
if (isset($config->$module->resources->layout->layout) && !$this->getRequest()->format)
{
$layoutScript = $config->$module->resources->layout->layout;
$this->getActionController()->getHelper('layout')->setLayout($layoutScript);
}
}
}
In a controller plugin I then want to get the whole of the response like so
$this->getResponse()->getBody()
This however only returns the output from the action, not the output from the layout too.
How can I get the whole output, layout and action together?
Thanks!
I believe that Zend_Layout operates at postDispatch() with a high stack index. So, to get the content, you might need to do your access later, at dispatchLoopShutdown().

I am trying to use the autocomplete addon in agile toolkit (I am still very much new to this, but it seems to be very well suited for my needs). Autocomplete Basic works, but when I use Plus and press the plus-button I get an error connected to no model set. In the Plus source the self-model should be used - but I don't understand how I should set the model of the autocomplete form.
This is the important part of the stack trace, I think:
Frontend_page_form: Form->setModel(Null)
Frontend_createquestions_form_question_id:
autocomplete\Form_Field_Plus->autocomplete{closure}(Object(Page))
This is my model:
class Model_QuestionInCollection extends Model_Table {
public $entity_code='questionincollection';
function init(){
parent::init();
$this->hasOne('Question')->display(array('form'=>'autocomplete/Plus'));
This is the code:
$form=$this->add('Form');
$form->setModel('QuestionInCollection');
--- EDIT
I ended up changing the model in autocomplete, and now it works, showing that something is wrong in the original "$self->model" - but of course it cannot be generalized. I did some extra changes (to make the new record show up in the autocomplete-field), so Autocomplete/Plus now is like this:
<?php
namespace autocomplete;
class Form_Field_Plus extends Form_Field_Basic
{
function init()
{
parent::init();
$self = $this;
$f = $this->other_field;
// Add buttonset to name field
$bs = $f->afterField()->add('ButtonSet');
// Add button - open dialog for adding new element
$bs->add('Button')
->set('+')
->add('VirtualPage')
->bindEvent('Add New Record', 'click')
->set(function($page)use($self) {
$model=$this->add('Model_Question');
$form = $page->add('Form');
$form->setModel($model); //Was: $self->model
//Would be nice if it worked...: $form->getElement($model->title_field)->set($self->other_field->js()->val());
if ($form->isSubmitted()) {
$form->update();
$js = array();
$js[] = $self->js()->val($form->model[$model->id_field]);
$js[] = $self->other_field->js()->val($form->model[$model->title_field]);
$form->js(null, $js)->univ()->closeDialog()->execute();
}
});
}
}
Here is an example on using autocomplete: http://codepad.demo.agiletech.ie/interactive-views/autocomplete
You can manually create a form and link the field with Model.
If that works fine, you can move on to trying and get your own example working. It seems OK, and should work in theory.
I'm working on an ACL which is called in Module.php and attached to the bootstrap.
Obviously the ACL restricts access to certain areas of the site, which brings the need for redirects. However, when trying to use the controller plugin for redirects it doesn't work as the plugin appears to require a controller.
What's the best way to redirect outside from outside of a controller? The vanilla header() function is not suitable as I need to use defined routes.
Any help would be great!
Cheers-
In general, you want to short-circuit the dispatch process by returning a response. During route or dispatch you can return a response to stop the usual code flow stop and directly finish the result. In case of an ACL check it is very likely you want to return that response early and redirect to the user's login page.
You either construct the response in the controller or you check the plugin's return value and redirect when it's a response. Notice the second method is like how the PRG plugin works.
An example of the first method:
use Zend\Mvc\Controller\AbstractActionController;
class MyController extends AbstractActionController
{
public function fooAction()
{
if (!$this->aclAllowsAccess()) {
// Use redirect plugin to redirect
return $this->redirect('user/login');
}
// normal code flow
}
}
An example like the PRG plugin works:
use Zend\Mvc\Controller\AbstractActionController;
use Zend\Http\Response;
class MyController extends AbstractActionController
{
public function fooAction()
{
$result = $this->aclCheck();
if ($result instanceof Response) {
// Use return value to short-circuit
return $result
}
// normal code flow
}
}
The plugin could then look like this (in the second case):
use Zend\Mvc\Controller\Plugin\AbstractPlugin;
class AclCheck extends AbstractPlugin
{
public function __invoke()
{
// Check the ACL
if (false === $result) {
$controller = $this->getController();
$redirector = $controller->getPluginManager()->get('Redirect');
$response = $redirector->toRoute('user/login');
return $response;
}
}
}
In your question you say:
[...] it doesn't work as the plugin appears to require a controller.
This can be a problem inside the controller plugin when you want to do $this->getController() in the plugin. You either must extend Zend\Mvc\Controller\Plugin\AbstractPlugin or implement Zend\Mvc\Controller\Plugin\PluginInterface to make sure your ACL plugin is injected with the controller.
If you do not want this, there is an alternative you directly return a response you create yourself. It is a bit less flexible and you create a response object while there is already a response object (causing possible conflicts with both responses), but the plugin code would change like this:
use Zend\Mvc\Controller\Plugin\AbstractPlugin;
use Zend\Http\PhpEnvironment\Response;
class AclCheck extends AbstractPlugin
{
public function __invoke()
{
// Check the ACL
if (false === $result) {
$response = new Response;
$response->setStatusCode(302);
$response->getHeaders()
->addHeaderLine('Location', '/user/login');
return $response;
}
}
}
I would like to have some input on the following:
I would like some views to be systematically rendered (I can call $this->render from
my layout for these views) regardless of which controller/action is executed.
However the content used in these views is based on the same dynamically generated data and the code behind it is quite complex so I can't put the logic inside the views for obvious optimization/performance issues.
I could use $this->_helper->actionStack in each controller to call another controller in which data for the views would be prepared however I would like to do without modifying the existing controllers
I would be tempted to put something in the bootstrap since what I want is common to my application however I just don't know what to do.
That's what View Helpers are for.
In the View Helper you can fetch your data (through models or service layer) and prepare it for output.
<?php
class View_Helper_Foobar extends Zend_View_Helper_Abstract
{
protected $_data;
public function foobar()
{
if (null !== $this->_data) {
$this->_data = some_expensive_data_getter();
}
return $this;
}
public function __toString()
{
return $this->view->partial('foobar.phtml', array('data' => $this->_data));
}
}
I want to display a page that has 2 forms. The top form is unique to this page, but the bottom form can already be rendered from a different controller. I'm using the following code to call the action of the other form but keep getting this error:
"Message: id is not specified"
#0 .../library/Zend/Controller/Router/Rewrite.php(441): Zend_Controller_Router_Route->assemble(Array, true, true)
My code:
First controller:
abc_Controller
public function someAction()
{
$this->_helper->actionStack('other','xyz');
}
Second controller:
xyz_Controller
public function otherAction()
{
// code
}
Desired results:
When calling /abc/some, i want to render the "some" content along with the xyz/other content. I think I followed the doc correctly (http://framework.zend.com/manual/en/zend.controller.actionhelpers.html) but can't find any help on why that error occurs. When I trace the code (using XDebug), the xyz/other action completes ok but when the abc/some action reaches the end, the error is thrown somewhere during the dispatch or the routing.
Any help is greatly appreciated.
You can accomplish this in your phtml for your someAction. So in some.phtml put <?php echo $this->action('other','xyz');?> this will render the form found in the otherAction of XyzController
The urge to do something like this is an indication you're going about it in totally the wrong way. If you have the urge to re-use content, it should likely belong in the model. If it is truly controller code it should be encapsulated by an action controller plugin
In phtml file u can use the $this->action() ; to render the page and that response would be added to current response ..
The syntax for action is as follows::
public function action($action, $controller, $module = null, array $params = array())
You can create new object with second controller and call its method (but it`s not the best way).
You can extend your first controller with the second one and call $this->methodFromSecond(); - it will render second form too with its template.
BTW - what type of code you want to execute in both controllers ?
Just an update. The error had absolutely nothing to do with how the action was being called from the second controller. It turns out that in the layout of the second controller, there was a separate phtml call that was throwing the error (layout/abc.phtml):
<?php echo $this->render('userNavigation.phtml') ?>
line of error:
echo $this->navigation()->menu()->renderMenu(...)
I'll be debugging this separately as not to muddy this thread.
Thanks to Akeem and hsz for the prompt response. I learned from your responses.
To summarize, there were 3 different ways to call an action from an external controller:
Instantiate the second controller from the first controller and call the action.
Use $this->_helper->actionStack
In the phtml of the first controller, action('other','xyz');?> (as Akeem pointed out above)
Hope this helps other Zend noobs out there.
Hm I can't find and idea why you need to use diffrent Controlers for one view. Better practise is to have all in one Controller. I using this like in this example
DemoController extends My_Controller_Action() {
....
public function indexAction() {
$this->view->oForm = new Form_Registration();
}
}
My_Controller_Action extends Zend_Controller_Action() {
public function init() {
parent::init();
$this->setGeneralStuf();
}
public function setGeneralStuf() {
$this->view->oLoginForm = new Form_Login();
}
}
This kind of route definition:
routes.abc.route = "abc/buy/:id/*"
routes.abc.defaults.controller = "deal"
routes.abc.defaults.action = "buy"
routes.abc.reqs.id = "\d+"
requires a parameter in order to function. You can do this with actionStack but you can also specify a default id in case that none is provided:
$this->_helper->actionStack('Action',
'Controller',
'Route',
array('param' => 'value')
);
routes.abc.defaults.id = "1"
For Me this worked like a charm
class abcController extends Zend_Controller_Action
{
public function dashBoardAction()
{
$this->_helper->actionStack('list-User-Data', 'xyz');
}
}
class XyzController extends Zend_Controller_Action {
public function listUserDataAction()
{
$data = array('red','green','blue','yellow');
return $data;
}
}
I am building a form in Zend Framework 1.9 using subforms as well as Zend_JQuery being enabled on those forms. The form itself is fine and all the error checking etc is working as normal. But the issue I am having is that when I'm trying to retrieve the values in my controller, I'm receiving just the form entry for the last subform e.g.
My master form class (abbreviated for speed):
Master_Form extends Zend_Form
{
public function init()
{
ZendX_JQuery::enableForm($this);
$this->setAction('actioninhere')
...
->setAttrib('id', 'mainForm')
$sub_one = new Form_One();
$sub_one->setDecorators(... in here I add the jQuery as per the docs);
$this->addSubForm($sub_one, 'form-one');
$sub_two = new Form_Two();
$sub_two->setDecorators(... in here I add the jQuery as per the docs);
$this->addSubForm($sub_two, 'form-two');
}
}
So that all works as it should in the display and when I submit without filling in the required values, the correct errors are returned. However, in my controller I have this:
class My_Controller extends Zend_Controller_Action
{
public function createAction()
{
$request = $this->getRequest();
$form = new Master_Form();
if ($request->isPost()) {
if ($form->isValid($request->getPost()) {
// This is where I am having the problems
print_r($form->getValues());
}
}
}
}
When I submit this and it gets past isValid(), the $form->getValues() is only returning the elements from the second subform, not the entire form.
I recently ran into this problem. It seems to me that getValues is using array_merge, instead of array_merge_recursive, which does render to correct results. I submitted a bug report, but have not gotten any feedback on it yet.
I submitted a bug report (http://framework.zend.com/issues/browse/ZF-8078). Perhaps you want to vote on it?
I think that perhaps I must have been misunderstanding the way that the subforms work in Zend, and the code below helps me achieve what I wanted. None of my elements share names across subforms, but I guess this is why Zend_Form works this way.
In my controller I now have:
if($request->isPost()) {
if ($form->isValid($request->getPost()) {
$all_form_details = array();
foreach ($form->getSubForms() as $subform) {
$all_form_details = array_merge($all_form_details, $subform->getValues());
}
// Now I have one nice and tidy array to pass to my model. I know this
// could also be seen as model logic for a skinnier controller, but
// this is just to demonstrate it working.
print_r($all_form_details);
}
}
I have a same problem to get value from subforms I solve it with this but not my desire one
code:
in controller i get value with this code that 'rolesSubform' is my subform name
$this->_request->getParam ( 'rolesSubform' );
Encountered the same problem. Used post instead of getValues.
$post = $this->getRequest()->getPost();
There are times when getValues does not return the same values returned by $post.
Must be a getValues() bug.
