zend form elements display hidden field value - zend-framework

$emailmessage = new Zend_Form_Element_Hidden('emailmessage');
the hidden filed value, i.e 'emailmessage' retrieves the value of the same field name inside the database. However on loading the page, value of the 'emailmessage' cannot be seen, since the element is hidden.
Is there any way to display it without using any other form elements. I want it without using text, textarea, etc.

in controller you need to assign it to view and in the view you can echo it where ever you want:
controller
$form = new Your_Form();
$this->view->emailmessage = $emailmessage;
View
echo $this->escape($this->emailmessage);

You need to set formNote decorator for the element.
You do it by extending Hidden element or by setting decorator in the form.
Form
public function init()
{
// ...
$emailMessage = new Zend_Form_Element_Hidden();
$emailMessage->setDecorators(
array(
array('ViewHelper', array('helper' => 'formNote'))
)
);
$this->addElement($emailMessage, 'emailMessage');
// ...
}

kendo ui set view model page data-title dynamically mvvm

I am trying to set the title of my view dynamically with no success so far.
I am trying something like this:
<div data-role="view"
id="mt-details-view"
data-title="#= pageTitle #" <---- this one
data-layout="mt-main-layout"
data-init="X.details.onInit"
data-before-show="X.details.beforeShow"
data-show="X.details.onShow"
data-model="X.details.viewModel"
data-use-native-scrolling="true">
I tried using a function, tried setting a viewModel variable, tried passing the title from the view.params, tried also to set the title on the onShow function like that:
function onShow(e) {
X.debug.dbg2(e.view.id, "onShow");
viewModel.setViewParams(e.view.params);
e.view.title = e.view.params.pageTitle;
e.view.options.title = e.view.params.pageTitle;
fetchSomeDetails();
}
nothing works.
Enlighten me please!
Here is one approach you can try. After declaring your viewmodel, bind a function to its 'set' method. Within here, check whether the field being set is the page title property on the viewmodel. If it is, find the dom element holding the title text and set its html to the value being 'set':
X.details.viewModel.bind("set", function(e) {
if (e.field == "pageTitle") {
$("#mt-details-view [data-role='view-title']").html(e.value);
}
})
Whenever that property is changed on the viewmodel, you will now see it reflected on the page. However there is still the issue of setting the value in the UI initially. You can do this in your onShow function which of course happens after the view is rendered and all the dom elements have been created:
function onShow(e) {
var temp = viewModel.pageTitle;
viewModel.set("pageTitle", null);
viewModel.set("pageTitle", temp);
}
That will force the 'set' method on the viewmodel to run and the UI should then update.

Symfony 2 Forms - add new item to Collection server-side, depending on button clicked

I have a form which contains a Collection of an unspecified number of subforms. I want to have functionality allowing the user to add a new, blank item to the Collection for them to fill in. The Symfony docs tell us how to do this using Javascript clientside to add new blank form controls, which are then submitted and persisted as normal, but I'd like to do it serverside in the controller, without Javascript.
The problem I'm encountering is to do with the way Symfony Forms work. I have an "Add" button added to my main form, and I intend to detect whether it is that button which has been clicked, so that I can add the blank item to the Collection and re-render the form. But to detect the click I need to call $this->createForm and at that point the form is fixed with the original set of items, it's too late to add an extra one.
//Symfony Action
//A Person has many Selections
$person = $this->getPerson($id)
//All fields are frozen at this point, according to data in $person!
$form = $this->createForm(new SelectionsType($lookups), $person);
$form->handleRequest($request);
//Ideally I'd somehow do this test earlier, but I need $form to do it...
if ($form->get('add')->isClicked() )
{
//TOO LATE!
$person->getSelections()->add(new Selection() );
}
if ($form->isValid())
{
if ($form->get('save')->isClicked() )
{
//Persist
}
}
//Render page etc
Things I've thought about:
Putting the Add button in a completely different form on the same page, which submits to a different Action which can then do some preparatory work before forwarding to the main Action above
Inspecting submitted HTTP data directly to note that Add has been clicked (shame not to use the standard Symfony method)
Give up and use Javascript as suggested (it might work in this example, but I'd like to have the option of carrying out server-side activity (without AJAX...) as part of adding the new blank item)
How can I best achieve this in a proper Symfony way?
EDIT Just seen this: https://github.com/symfony/symfony/issues/5231, which is essentially a feature request to allow what I'm after. One suggestion a commenter makes is to add a blank item to the Collection and then remove it if it's not needed - I don't know how one would do that, but it sounds promising.
ANOTHER EDIT It occurs to me that, because I need two different aspects of the $form I'm creating, I could maybe just make the $form, use it to handle the request, detect the button click, and then throw that $form away, before altering my model and creating another $form. I don't know if that would somehow fall foul of some rules about handling the submission twice.
I'm not 100% but I think you could do the following...
//Symfony Action with (Request $request, ...)
//A Person has many Selections
$person = $this->getPerson($id)
//All fields are frozen at this point, according to data in $person!
$form = $this->createForm(new SelectionsType($lookups), $person);
if ($request->isMethod('POST')) {
$form->submit($request);
if ($form->get('add')->isClicked()) {
// Add thing
} elseif ($form->isValid()) {
// or
// } elseif ($form->get('save')->isClicked() && $form->isValid()) {
// Persist and what not
}
}
//Render page etc
I haven't tested it so I don't know whether it will trigger the form errors (or if it will actually work) so if it does (or it doesn't) I apologise.
What I did in the end was have my Add button hit a separate Action, which then delegates to the main action with a flag to say "add a new Selection", as below:
public function selectionsAddAction(Request $request, $id)
{
return $this->selectionsAction($request, $id, true);
}
public function selectionsAction(Request $request, $id, $addNew = false)
{
$person = $this->getPerson($id);
//Also use "add mode" if we just deleted the last one!
if (!$person->getSelections()->count())
{
$addNew = true;
}
//$addNew is set by a separate action, hit by a different form with the Add button in
if ($addNew)
{
$person->getSelections()->add(new Selection() );
}
//We now have the right number of items, and can build the form!
$form = $this->createForm(new SelectionsType($lookups), $person);
//...
}

adding Zend_Form_Element_Captcha to form causes form to not display

I am having trouble getting a captcha element to display in a signup form. It was working previously, but now for some reason when I try to add the captcha element to the form the entire form does not display.
Below is the function in my controller file to create the form
private function getSignupForm()
{
// create form
$form = new Zend_Form();
$form->setAction('success');
$form->setMethod('post');
$form->setAttrib('sitename', 'loudbite');
// add elements
require "form/elements.php";
$loudbiteElements = new Elements();
// create username field
$form->addElement($loudbiteElements->getUsernameTextField());
// create email field
$form->addElement($loudbiteElements->getEmailTextField());
// create password field
$form->addElement($loudbiteElements->getPasswordTextField());
// add captcha
$form->addElement($loudbiteElements->getCaptcha());
// create submit button
$form->addElement('submit', 'submit');
$submitElement = $form->getElement('submit');
$submitElement->setLabel('Create My Account!');
return $form;
}
and here is the action to pass the form to the corresponding view
public function newAction()
{
// get the form
$form = $this->getSignupForm();
// add the form to the view
$this->view->form = $form;
}
If I comment out the line in my getSignupForm() function where I add the captcha to the form then the form will display ok minus the captcha element. This leads me to assume that there is a problem with the captcha contruction.
Below is the function in an external model file where the captcha is constructed
public function getCaptcha()
{
$captchaElement = new Zend_Form_Element_Captcha(
'signup',
array('captcha' => array(
'captcha' => 'Figlet',
'wordLen' => 6,
'timeout' => 600))
);
$captchaElement->setLabel('Please type in the words below to continue:');
return $captchaElement;
}
All the other form elements are created in this external model file. Based on the fact that the other elements display correctly if I do not add the captcha element, I assume it is not a problem with accessing the model file.
The last time I used this signup form everything was working ok! And I don't remember having changed anything between then and now.
Any help is greatly appreciated.

Symfony2: get rid of "This form should not contain extra fields"

I have added a second submit button to my form, now Symfony2 complains about it: "This form should not contain extra fields"
Although I added this option in the formtype:
public function getDefaultOptions(array $options)
{
return array(
'csrf_protection' => false,
);
}
Any ideas?
You can most certainly have multiple submit buttons. Make sure the button is not in the same array as the other form fields.
So, for example, if your form fields have a name FormType[field_name], you can't have FormType[submit_btn] as the name of the button and you must choose a different one.
Your controller can act differently depending on the button pressed. If your submit buttons are named submit_1 and submit_2 you can have something similar to
if($this->getRequest()->request->has('submit_1')) {
// do stuff
} else {
// do other stuff
}

Zend_Navigation: Having trouble getting breadcrumbs to render using multiple containers [duplicate]

This question already has answers here:
Closed 10 years ago.
Possible Duplicate:
Zend Framework - multiplate navigation blocks
I'm trying to make breadcrumbs render in my application ( they don't show up anywhere, not even the homepage, which has a corresponding Zend Page Uri object ), which has multiple navigation areas - primary and utility. For the menu generation, I have a MenuController which I render with from within the layout using:
$this->layout()->utility = $this->action('render', 'menu', null, array('menu' => $this->utilityId));
$this->layout()->nav = $this->action('render', 'menu', null, array('menu' => $this->mainMenuId));
The utilityId and mainMenuId properties are numbers, grabbed from a database.
The Menu controller's render method just builds an array and creates a Zend Navigation object, then invokes setContainer and sets it to that container. This is pseudo code because it's rather long:
// MenuController.php
private function renderAction() {
$itemArray[] = array('label' => $label, 'uri' => $uri ); // in a loop
$container = new Zend_Navigation($itemArray);
if ( $container instanceof Zend_Navigation_Container ) {
$this->view->navigation()->setContainer( $container );
$uri = $this->_request->getPathInfo();
$item = $this->view->navigation()->findByUri($uri);
$item->active = true;
}
}
So this render method is called twice from within the layout for the utility and nav.
EDIT:
I think the issue is that I need to specify the $container so my code would be
$this->navigation($container)->breadcrumbs();
However because I'm using $this->action('render', 'menu' ) the $container variable is set there and not returned, is there a way I can specify the container some other way? Possibly using $this->layout()->nav and a property in that which points to the container.
This looks like it's the same issue and someone suggests setting/getting them with Zend_Registry, perhaps I'll try this out.
I suspect you don't have a navigational hierarchy. You need pages within pages.
e.g.
Home Page
[pages] => Sign In
[pages] => Forgot Password
=> Create Account
[pages] => Confirm Account Email
=> Email Confirmed
With the above, breadcrumbs will be rendered on all active pages except for the Home Page... all pages if you do this:
$this->navigation()->breadcrumbs()->setMinDepth(0); // don't skip the root page
Or maybe it's something else, but it's hard to say. I hope that helps, though!
This is probably a dirty solution, but I manually set the container reference using Zend_Registry like so:
Zend_Registry::set( 'nav' . $menu, $container );
And spit it out like so:
$main = Zend_Registry::get( 'nav' . $this->mainMenuId );
echo $this->navigation( $main )->breadcrumbs()->setMinDepth(0);
