Zend - Add subForm to existing display group - zend-framework

In my controller I got a function which looks like this:
public function newExperienceAction() {
$this->_helper->layout->disableLayout();
$ajaxContext = $this->_helper->getHelper('AjaxContext');
$ajaxContext->addActionContext('newExperience', 'html')->initContext();
$id = $this->_getParam('id', null);
$this->form = new Application_Form_Cv();
$this->experience = new Zend_Form_SubForm();
$this->form->addSubForm($this->experience, 'experience');
$rowExperience = new Application_Form_Experience();
$rowExperience->setDisplayGroups('experience');
$this->experience->addSubForm($rowExperience, "experience$id", $id+3);
echo $rowExperience->__toString();
}
When the user press (+) on the form, a new subForm will be displayed.
I'm currently in the process if shaping it into a table. I will have more than one subForm on this form so I need to use DisplayGroups.
In this situation, I believe I have to create a Display group when the form is first created.
Then I need to append the new subForms to the existing display groups.
So the question:
How do I add new subForms to an existing display group?

You can achieve this by simply adding
$rowExperience->setIsArray(true);
This causes the sub-form to act like a display group, i.e. its values are wrapped in an array indexed by the sub-form's name (experience$id in your case).

I'm afraid this is not possible now. I'm using Zend Framework version 1.11.7 and the code of the addDisplayGroup method looks like that:
foreach ($elements as $element) {
if($element instanceof Zend_Form_Element) {
(...)
}
if (isset($this->_elements[$element])) {
(...)
}
}
So this is not supported yet. You can add only Zend_Form_Element instances

ZF2 layout form set input filters and validation

For my application in Zend Framework 2 I created a 'search form' in my layout.phtml.
I did this in my Application module by adding the search form as an variable.
(Form location Application/src/Application/Form/SearchForm.php)
Application/Module.php:
public function setFormToView($e)
{
$searchForm = new SearchForm();
$viewModel = $e->getViewModel();
$viewModel->setVariables(array(
'searchForm' => $searchForm,
));
}
The form directs to an Action in another module, here I want to handle what to do with
the incoming query.
MyModule/src/MyModule/Controller/MyModuleController.php
public function dataAction()
{
$form = new SearchForm();
$form->get('submit')->setValue('Add');
$website = $this->params()->fromQuery('search');
return array('searchForm', $form);
}
Getting the query 'search' is no problem, it works well. No I want to use my inputFilter I created under 'Application/src/Application/Model/Search.php'.
I tried to add this in my 'dataAction()' but no results, but I even can't change the submit value as I tried in my example above.
How do I set this in the right way in this situation? Or else, what is the right situation to handle a search form in layout.phtml.
Thanks in advance,
Nick

Zend Framework: Form Validation - Please Fill In 'A' or 'B'

I'm writing an application with Zend Framework. I have a simple form that has two text boxes.
How do I add validation to the form so that at least one of the input boxes should be populated?
You could create a custom validator, something like:
class My_Validate_AtLeastOneNotEmpty implements Zend_Validate_Interface
{
protected $thisField;
protected $otherField;
protected $messages = array();
public function __construct($thisField, $otherField){
$this->thisField = $thisField;
$this->otherField = $otherField;
}
public function isValid($value, $context = null)
{
$validator = new Zend_Validate_NotEmpty();
if (!$validator->isValid($value) && !$validator->isValid($context['otherField'])){
$this->messages[] = 'At least one of the fields - '
. $thisField . ' or ' . $otherField
. ' - must be non-empty';
return false;
}
return true;
}
public function getMessages()
{
return $this->messages;
}
}
Then attach this validator to one of the elements, identifying both names:
// create the two fields
$fld1 = new Zend_Form_Element_Text('field1');
$fld2 = new Zend_Form_Element_Text('field2');
// add the validator to one of them, identifying both fields
$fld1->addValidator(new My_Validate_AtLeastOneNotEmpty('field1', 'field2'));
Typically, we would not need to identify the fieldname of the element to which we are attaching the validator. However, by passing both fieldnames to the validator, we can make the error message a little clearer for the user.
Create a radio group with two options, both unchecked. Hide the textfields. With an onclick event on the radio buttons you can show one of the textboxes. Now you can add a required validator to the radio buttons. A little workaround, but the result is the same.

Symfony: How to hide form fields from display and then set values for them in the action class

I am fairly new to symfony and I have 2 fields relating to my table "Pages"; created_by and updated_by. These are related to the users table (sfGuardUser) as foreign keys. I want these to be hidden from the edit/new forms so I have set up the generator.yml file to not display these fields:
form:
display:
General: [name, template_id]
Meta: [meta_title, meta_description, meta_keywords]
Now I need to set the fields on the save. I have been searching for how to do this all day and tried a hundred methods. The method I have got working is this, in the actions class:
protected function processForm(sfWebRequest $request, sfForm $form)
{
$form_params = $request->getParameter($form->getName());
$form_params['updated_by'] = $this->getUser()->getGuardUser()->getId();
if ($form->getObject()->isNew()) $form_params['created_by'] = $this->getUser()->getGuardUser()->getId();
$form->bind($form_params, $request->getFiles($form->getName()));
So this works. But I get the feeling that ideally I shouldnt be modifying the web request, but instead modifying the form/object directly. However I havent had any success with things like:
$form->getObject()->setUpdatedBy($this->getUser()->getGuardUser());
If anyone could offer any advice on the best ways about solving this type of problem I would be very grateful.
Thanks,
Tom
After processing and saving the form you could set those fields on the object and re-save:
protected function processForm(sfWebRequest $request, sfForm $form)
{
$form->bind($request->getParameter($form->getName()));
if ($form->isValid())
{
$page = $form->save();
$user = $this->getUser()->getGuardUser();
$page->setUpdatedBy($user);
if (empty($page->created_by))
{
$page->setCreatedBy($user);
}
$page->save();
$this->getUser()->setFlash('notice', 'Successfully saved page.');
$this->redirect('#homepage');
}
}
There's also a Doctrine extension called Blameable that automatically sets edited_by and created_by fields on specified models. The Doctrine website is undergoing some reorganization but here is the cached page for the extension.
To process your form create a new object, set the fields then save.
$article = new Article();
$article->setName($request->getParameter($form->getName());
$article->setDescription($request->getParameter($form->getDescription());
$article->setMetaKeywords($request->getParameter($form->getMetaKeywords());
$article->save();
What you want to do is customize your form and unset the 'created_at' and 'updated_at' pieces of the form in configure
class SampleForm extends BaseSampleForm
{
public function configure()
{
unset(
$this['created_at'],
$this['updated_at']
);
}
}
Then they won't show up in the form and will get the values setup by the "Timestampable" behavior before being saved

Zend_Form using subforms getValues() problem

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.

Zend Framework: How to display multiple actions, each requiring different authorizations levels, on a single page

Imagine I have 4 database tables, and an interface that presents forms for the management of the data in each of these tables on a single webpage (using the accordion design pattern to show only one form at a time). Each form is displayed with a list of rows in the table, allowing the user to insert a new row or select a row to edit or delete. AJAX is then used to send the request to the server.
A different set of forms must be displayed to different users, based on the application ACL.
My question is: In terms of controllers, actions, views, and layouts, what is the best architecture for this interface?
For example, so far I have a controller with add, edit and delete actions for each table. There is an indexAction for each, but it's an empty function. I've also extended Zend_Form for each table. To display the forms, I then in the IndexController pass the Forms to it's view, and echo each form. Javascript then takes care of populating the form and sending requests to the appropraite add/edit/delete action of the appropriate controller. This however doesn't allow for ACL to control the display or not of Forms to different users.
Would it be better to have the indexAction instantiate the form, and then use something like $this->render(); to render each view within the view of the indexAction of the IndexController? Would ACL then prevent certain views from being rendered?
Cheers.
There are a couple of places you could run your checks against your ACL:
Where you have your loop (or hardcoded block) to load each form.
In the constructor of each of the Form Objects, perhaps throwing a custom exception, which can be caught and appropriately handled.
From the constructor of an extension of Zend_Form from which all your custom Form objects are extended (probably the best method, as it helps reduce code duplication).
Keep in mind, that if you are using ZF to perform an AJAXy solution for your updating, your controller needs to run the ACL check in it's init() method as well, preventing unauthorized changes to your DB.
Hope that helps.
Have you solved this one yet?
I'm building a big database app with lots of nested sub-controllers as panels on a dashboard shown on the parent controller.
Simplified source code is below: comes from my parentController->indexAction()
$dashboardControllers = $this->_helper->model( 'User' )->getVisibleControllers();
foreach (array_reverse($dashboardControllers) as $controllerName) // lifo stack so put them on last first
{
if ($controllerName == 'header') continue; // always added last
// if you are wondering why a panel doesn't appear here even though the indexAction is called: it is probably because the panel is redirecting (eg if access denied). The view doesn't render on a redirect / forward
$this->_helper->actionStack( 'index', $this->parentControllerName . '_' . $controllerName );
}
$this->_helper->actionStack( 'index', $this->parentControllerName . '_header' );
If you have a better solution I'd be keen to hear it.
For my next trick I need to figure out how to display these in one, two or three columns depending on a user preference setting
I use a modified version of what's in the "Zend Framework in Action" book from Manning Press (available as PDF download if you need it now). I think you can just download the accompanying code from the book's site. You want to look at the Chapter 7 code.
Overview:
The controller is the resource, and the action is the privilege.
Put your allows & denys in the controller's init method.
I'm also using a customized version of their Controller_Action_Helper_Acl.
Every controller has a public static getAcls method:
public static function getAcls($actionName)
{
$acls = array();
$acls['roles'] = array('guest');
$acls['privileges'] = array('index','list','view');
return $acls;
}
This lets other controllers ask about this controller's permissions.
Every controller init method calls $this->_initAcls(), which is defined in my own base controller:
public function init()
{
parent::init(); // sets up ACLs
}
The parent looks like this:
public function init()
{
$this->_initAcls(); // init access control lists.
}
protected function _initAcls()
{
$to_call = array(get_class($this), 'getAcls');
$acls = call_user_func($to_call, $this->getRequest()->getActionName());
// i.e. PageController::getAcls($this->getRequest()->getActionName());
if(isset($acls['roles']) && is_array($acls['roles']))
{
if(count($acls['roles'])==0) { $acls['roles'] = null; }
if(count($acls['privileges'])==0){ $acls['privileges'] = null; }
$this->_helper->acl->allow($acls['roles'], $acls['privileges']);
}
}
Then I just have a function called:
aclink($link_text, $link_url, $module, $resource, $privilege);
It calls {$resource}Controller::getAcls() and does permission checks against them.
If they have permission, it returns the link, otherwise it returns ''.
function aclink($link_text, $link_url, $module, $resource, $privilege)
{
$auth = Zend_Auth::getInstance();
$acl = new Acl(); //wrapper for Zend_Acl
if(!$acl->has($resource))
{
$acl->add(new Zend_Acl_Resource($resource));
}
require_once ROOT.'/application/'.$module.'/controllers/'.ucwords($resource).'Controller.php';
$to_call = array(ucwords($resource).'Controller', 'getAcls');
$acls = call_user_func($to_call, $privilege);
if(isset($acls['roles']) && is_array($acls['roles']))
{
if(count($acls['roles'])==0) { $acls['roles'] = null; }
if(count($acls['privileges'])==0){ $acls['privileges'] = null; }
$acl->allow($acls['roles'], $resource, $acls['privileges']);
}
$result = $acl->isAllowed($auth, $resource, $privilege);
if($result)
{
return ''.$link_text.'';
}
else
{
return '';
}
}
