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.

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);
//...
}
$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');
// ...
}
For Magento Backend I created a Varien_Form to display.
class MyNamespace_MyModule_Block_Adminhtml_MyModule_Edit_Tabs_Form
extends Mage_Adminhtml_Block_Widget_Form {
protected function _prepareForm()
{
$form = new Varien_Data_Form();
$this->setForm($form);
$fieldset = $form->addFieldset('my_form', array('legend'=>'ABC'));
$fieldset->addField('data', 'text',
array(
'label' => 'My Textfield',
'name' => 'myTextField'
));
return parent::_prepareForm();
}
}
My question is now, which form fields are possible at all? You see the function addField() where it says 'text'? I heard of 'checkbox' and 'hidden'. But is there a list of all possible fields? Like Label or a textbox for more lines etc. Thanks a lot!
The different form elements you can use are all found in lib/Varien/Data/Form/Element, you can find help using some of them at http://www.excellencemagentoblog.com/magento-admin-form-field
You can use textarea for a multiline textbox.
Here is a list of possible field types:
text
time
textarea
submit
select
radio
password
note
multiselect
link
label
image
file
date
checkbox
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
}
I have spent hours on the net to find a solution, but nothing works.
I have a form divided into 2 subForms (I couldn't get the accordion pane to work)
like this :
$sfBase = new Zend_Dojo_Form_SubForm('base_info');
$sfBase->setName('base_info')
->setAction('/product/add?f=1');
$id = new Zend_Form_Element_Hidden('id');
$id->addFilter('Int')
->setAttrib('style', 'display:none');
$nom = new Zend_Dojo_Form_Element_TextBox('name');
$nom->setLabel('Nom du produit')
->setTrim(true)
->setValue("Entrez le nom")
->setPropercase(true);
$sdesc = new Zend_Dojo_Form_Element_TextBox('sdesc');
$sdesc->setLabel('Courte description du produit')
->setTrim(true)
->setValue("Description")
->setPropercase(true);
$sfBase->addElements(array($id, $nom, $sdesc);
$submitSubBase = new Zend_Dojo_Form_Element_SubmitButton('sub1');
$submitSubBase->setLabel('ok');
$sfBase->addElement($submitSubBase);
and another subform which contains few other elements :
$sfComp = new Zend_Dojo_Form_SubForm('comp_info');
$sfComp->setName('comp_info')
->setAction('/product/add?f=2');
...
$submitSubComp = new Zend_Dojo_Form_Element_SubmitButton('sub2');
$submitSubComp->setLabel('envoyer');
$sfComp->addElement($submitSubComp);
$this->addSubForms(array('base_info' => $sfBase,
'comp_info' => $sfComp
));
In my controller I display the entire instanciated form :
$this->view->base = $form;
but whenever I click on a submit button nothing happens. I tried placing a single submit button added to the form (not to a subForm)
with setAction :
$baseForm->setAction($this->view->url(
array('controller' => 'Product', 'action' => 'add', 'id' => '1'), 'default',
true));
but it is the same, finally I divided the form into two distinct Zend_Form instead of subforms, but that is not very clean...
So having tried multi page forms, subForms and dojo containers unsuccessfully I don't know what to do, and any help would be welcome !
thank you
I don't know if this will help at all but here is my answer.
If the MAIN form is not Dojo enabled, have you called Zend_Dojo::enableForm() in the init method? Is the MAIN form extending frorm Zend_Dojo_Form? If it's extending from Zend_Dojo_Form then you don't have to call Zend_Dojo::enableForm().
The Dojo forms submit through the use of javascript. You should have some javascript on the client side that can handle the responses from the server that will come back. If you don't have javascript on the client side to handle these returns, then you won't 'see' the results of the submit.
Try this, write some javascript using the dojo toolkit that will create an alert box when it receives something from the server. This way, if you click on the submit button and an alert box comes up you'll know that the form was submitted.
