I have two issues while using the Zend-Form date element.
First: field binding
The edit action within my controller doesn't fillin an existing date. For example birthday. The field is just empty. (with an element type text, there is no problem).
Here how I instanciated the field:
$this->add([
'name' => 'geburtstag',
'type' => 'date',
'options' => [
'label' => 'Geburtstag:',
'format' => 'dd/mm/yyyy',
],
]);
And here my controller action.
public function addAction()
{
$form = new AnsprechpartnerForm(NULL, $this->db);
$form->get('submit')->setValue('save');
$request = $this->getRequest();
if (! $request->isPost()) {
return ['form' => $form];
}
$ansprechpartner = new Ansprechpartner();
$form->setInputFilter($ansprechpartner->getInputFilter());
$form->setData($request->getPost());
if (! $form->isValid()) {
return ['form' => $form];
}
$ansprechpartner->exchangeArray($form->getData());
$this->ansprechpartnerTable->saveAnsprechpartner($ansprechpartner);
return $this->redirect()->toRoute('ansprechpartner');
}
No inputFilter at the moment, I tried with and without.
Second: validation
I have trouble filling in dates. While I don't use any filters for this field, I would expect, I could fill any date in.
Interesting I get the message double.
I solved it.
The date element expects the format y-m-d. Now I gave it directly to the field after binding the form. The format in the field is now also korrekt.
$form->bind($notizen);
$form->get('submit')->setAttribute('value', 'edit');
$filter = new \Zend\Filter\DateTimeFormatter();
$filter->setFormat('Y-m-d');
$dat = $filter->filter($notizen->datum);
$form->get('datum')->setValue($dat);
Could be more convenient I guess.

I have a controller action the prompts the user for some free text input. When submitted the text is parsed into some number of objects that I want to put out on another form for the user to confirm that the initial parsing was done correctly.
Normally after dealing with the response to a form submission we call $this->redirectToRoute() to go off to some other path but I have all these objects laying around that I want to use. If I redirect off someplace else I lose them.
How can I keep them? I tried building my new form right there in the controller action method but then its submission does not seem to be handled properly.
/**
* #Route( "/my_stuff/{id}/text_to_objects", name="text_to_objects" )
*/
public function textToObjects( Request $request, Category $category ) {
$form = $this->createForm( TextToObjectsFormType::class, [
'category' => $category,
]);
$form->handleRequest( $request );
if( $form->isSubmitted() && $form->isValid() ) {
$formData = $form->getData();
$allTheStuff = textParserForStuff( $formData['objectText'] );
$nextForm = $this->createForm( StuffConfirmationFormType::class, $allTheStuff );
return $this->render( 'my_stuff/confirmation.html.twig', [
'form' => $nextForm->createView(),
'category' => $category,
] );
}
return $this->render( 'my_stuff/text.html.twig', [
'form' => $form->createView(),
'category' => $category,
] );
}
This does fine to the point of displaying the confirmation form but when I submit that form I just end up displaying the original TextToObjects form?
To answer albert's question, the TextToObjectsFormType just has three fields, a way to set the date & time for the group of generated objects, a way to select the origin of the objects and a textarea for the textual description. I do not set a data_class so I get an associative array back with the submitted information.
class TextToObjectsFormType extends AbstractType {
public function buildForm( FormBuilderInterface $builder, array $options ) {
$builder
->add( 'textSourceDateTime', DateTimeType::class, [
'widget' => 'single_text',
'invalid_message' => 'Not a valid date and time',
'attr' => [ 'placeholder' => 'mm/dd/yyyy hh:mm',
'class' => 'js-datetimepicker', ],
])
->add( 'objectsOrigin', EntityType::class, [
'class' => ObjectSourcesClass::class,
])
->add( 'objectText', TextareaType::class, [
'label' => 'Copy and paste object description text here',
]);
}
}
How can I get the confirmed, potentially revised, objects back to put them into the database?
Thanks.
Using your current architecture
$nextForm = $this->createForm( StuffConfirmationFormType::class, $allTheStuff );
does not bear enough information. It should contain the action parameter to tell the submission to where route the post request.
In your StuffConfirmationFormType add an 'objectText' field hidden.
Create a confirmation_stuff route
Create an action for this route
In this action if the form is valid => save your stuff ELSE re render TextToObjectsFormType with an action linked to text_to_objects
Be aware that using this technique would not prevent a user to enter non functional data by manually editing the hidden field.
Hope this helps
A dropdown selection menu in a Form is available by using a EntityType form type. It is usefull if you add data. But when you try to edit data with the same FormType class, your $request data are overwritten by your EntityType.
How use the same FormType class when editing the data? (eg. editAction in controller) How pass Request $request data to FormType fields as "defaults, or selected" for element EntityType::class in FormBuilder? Is there something in $builder->add() method I can use like if(['choice_value'] !=== null ) xx : yy?
How to get something like html select selected, from Request object and pass it to xxxFormType class and bind to right EntityType::class element there.
<select>
<option value="volvo">Volvo</option>
<option value="vw">VW</option>
<option value="audi" selected>Audi</option>
</select>
I've looked at EntityType Field,
How to Dynamically Modify Forms Using Form Events and lots of StackOverflow posts, but can't find proper solution.
Controller:
public function editProdPackageAction(Request $request, ProdPackage $prodPackage)
{
$form = $this->createForm(ProdPackageFormType::class, $prodPackage);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$prodPackage = $form->getData();
$em = $this->getDoctrine()->getManager();
$em->persist($prodPackage);
$em->flush();
$this->addFlash('success', 'MSG#011E');
return $this->redirectToRoute('admin_package_list');
}
return $this->render(':admin/forms/ProdPackage:edit.html.twig',
[
'ppg' => $form->createView(),
]
);
}
Formtype:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add(
'idCatBig',
EntityType::class,
[
'label' => '* category',
'class' => 'AppBundle\Entity\ProdCategoryBig',
'choice_value' => 'id',
'choice_label' => 'shortName',
'multiple' => false,
'expanded' => false,
]
)
->add(
'dateStart',
DateType::class,
[
'label' => '* some date',
'data' => new \DateTime('now'),
'choice_translation_domain' => true,
]
)
->add(
'dateEnd',
DateType::class,
[
'label' => '* till',
'data' => new \DateTime('now'),
]
)
->add(
'packageName',
TextType::class,
[
'label' => '* package',
'attr' => ['placeholder' => 'default Name'],
'data' => 'your default value',
]
)
This is what I do in my form, I set a "pre set data listener" to check whether or not this is an edit or a create
function buildForm(FormBuilderInterface $builder, array $options) {
$builder->add(
'dateStart',
DateType::class,
[
'label' => '* some date'
//I don't set a data field here because it is an edit
'choice_translation_domain' => true,
]
)
$builder->addEventListener(FormEvents::PRE_SET_DATA, function (FormEvent $event) {
$data = $event->getData();
$form = $event->getForm();
if (!$data || null === $data->getId()) {
//if the entity does not have an ID it means that this is a new entity not an edit. because all edits have been in the database and have an id
$builder->add(
'dateStart',
DateType::class,
['label' => '* some date',
'data' => new \DateTime('now'), //this is a create so I override my previous setting and set a default data
'choice_translation_domain' => true,]
)
}
});
}
I mainly use this trick to change form fields from required to non required between edits and creates for password fields for example,and sometimes if there is something exceedingly complicated. To change data, honestly, setting default data in constructor is cleaner as Stephan suggests
Problem
You are overriding an object by using the data option.
https://symfony.com/doc/3.2/reference/forms/types/entity.html#data:
( ! ) The data option always overrides the value taken from the domain data (object) when rendering. This means the object value is also overriden when the form edits an already persisted object, causing it to lose its persisted value when the form is submitted.
Solution 1: use the controller
So the solution is pretty simple: don't use data. Instead, set default values in your addProdPackageAction action (or whatever it is called):
public function editProdPackageAction(Request $request)
{
$prodPackage = new ProdPackage();
$prodPackage->setDateEnd(new Datetime('now'));
//example: use Request or other controller methods to modify your entity
if ($this->getUser()->hasRole('ROLE_ADMIN')) {
$prodPackage->setCreatedByAdmin(true);
}
//your form
}
Solution 2: use your entity constructor
Alternatively, you can use your entity constructor method:
class ProdPackage
{
//your attributes
private $dateEnd;
public function __construct()
{
$this->dateEnd = new Datetime('now');
}
}
Found another interesting solution
in formTypeclass at $builder
->add(
'trBegin',
DateTimeType::class,
[
'label' => 'Tourney Begins',
'required' => true,
'date_widget' => 'single_text',
'time_widget' => 'single_text',
'date_format' => 'dd.MM.yyyy',
]
)
and continuing building form add:
$builder->get('trBegin')->addModelTransformer(
new CallbackTransformer(
function ($value) {
if (!$value) {
return new \DateTime('now + 60 minutes');
}
return $value;
},
function ($value) {
return $value;
}
)
);
it sets default date at moment when form is created. This method is very usefull also for EntityType object, where you can pass id of field in form and get selected your current real choice from database (not all list from the begining) very useful when using EntityField also for editing forms
$builder->get('productCategory')
->addModelTransformer(new CallbackTransformer(
function ($id) {
if (!$id) {
return;
}
return $this->em->getRepository('AppBundle:ProductCategory')->find($id);
},
function($category) {
return $category->getId();
}
));
I'm trying to add values into each element of a collection from a multiple form, but I got this :
Call to a member function getQuestions() on a non-object
What is the correct syntax?
This is my code:
$repository = $this->getDoctrine()->getManager()
->getRepository('***Bundle:Projet');
$projet = $repository->find($projetid);
$formBuilder = $this->createFormBuilder($projet);
$formBuilder->add('questions','collection',array(
'type' => new QuestionType(),
'allow_add' => true,
'allow_delete' => true
));
$form = $formBuilder->getForm();
if ($request->getMethod() == 'POST') {
$form->bind($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$membreid = $this->getUser()->getId();
$questions = $projet->getQuestions();
//I'm gonna do a loop here
$questions[0]->setMembreId($membreid);
$projet->addQuestion($questions[0]);
$em->persist($projet);
$em->flush();
return $this->redirect($this->generateUrl('***_nouveau_projet',array('etape' => 3, 'id' => $projet->getId() )));
}
}
return $this->render('***:nouveau_projet.html.twig',array(
'form' => $form->createView(),
'etape' => $etape,
'projet' => $projetid,
));
The error message you got provides relevant clues about what's going wrong.
getQuestions() is called on a non object.
Make sure $project is an instance of ***Bundle:Projet and that
$repository->find($projetid); is returning a valid object.
Probably that the given $projetid doesn't match any record in your date source.
I've a password form field (not mapped to User password) to be used in a change password form, along with two other (mapped) fields, first and last.
I've to add validators on the fly: if value for password is blank then no validation should occur. Otherwise a new MinLength and MaxLength validators should be added.
Here is what i've done so far: create the repeated password field, add a CallbackValidator and return if $form->getData() is null.
Then, how can i add validators for minimum and maximum length to $field?
$builder = $this->createFormBuilder($user);
$field = $builder->create('new_password', 'repeated', array(
'type' => 'password',
'first_name' => 'Password',
'second_name' => 'Confirm password',
'required' => false,
'property_path' => false // Not mapped to the entity password
));
// Add a callback validator the the password field
$field->addValidator(new Form\CallbackValidator(function($form) {
$data = $form->getData();
if(is_null($data)) return; // Field is blank
// Here password is provided and match confirm, check min = 3 max = 10
}));
// Add fields to the form
$form = $builder
->add('first', 'text', array('required' => false)) // Mapped
->add('last', 'text', array('required' => false)) // Mapped
->add($field) // Not mapped
->getForm();
Oh well, found a solution myself after a few experiments.
I'm going to leave this question unanswered for a couple of days as one can post a better solution, that would be really really welcome :)
In particular, i found the new FormError part redundat, don't know if there is a better way to add the error to the form. And honestly, don't know why new Form\CallbackValidator works while new CallbackValidator won't.
So, don't forget to add use statements like these:
use Symfony\Component\Form as Form, // Mendatory
Symfony\Component\Form\FormInterface,
Symfony\Component\Validator\Constraints\MinLength,
Symfony\Component\Validator\Constraints\MinLengthValidator;
And the callback is:
$validation = function(FormInterface $form) {
// If $data is null then the field was blank, do nothing more
if(is_null($data = $form->getData())) return;
// Create a new MinLengthValidator
$validator = new MinLengthValidator();
// If $data is invalid against the MinLength constraint add the error
if(!$validator->isValid($data, new MinLength(array('limit' => 3)))) :
$template = $validator->getMessageTemplate(); // Default error msg
$parameters = $validator->getMessageParameters(); // Default parameters
// Add the error to the form (to the field "password")
$form->addError(new Form\FormError($template, $parameters));
endif;
};
Well, and this is the part i can't understand (why i'm forced to prefix with Form), but it's fine:
$builder->get('password')->addValidator(new Form\CallbackValidator($validation));
addValidator was deprecated and completly removed since Symfony 2.3.
You can do that by listening to the POST_SUBMIT event
$builder->addEventListener(FormEvents::POST_SUBMIT, function ($event) {
$data = $event->getData();
$form = $event->getForm();
if (null === $data) {
return;
}
if ("Your logic here") {
$form->get('new_password')->addError(new FormError());
}
});
My Goal is if user is submitting this form with "Product Name" value as "YYY". On submit page should reload but this time "Product Name" should show previous valye as default as in this case "YYY".
Here is my code...
function addnewproduct_page () {
return drupal_get_form('addnewproduct_form',&$form_state);
}
function addnewproduct_form(&$form_state) {
$form = array();
$formproductname['productname'] = array (
'#type' => 'textfield',
'#title' => t('Product Name'),
'#required' => TRUE,
'#size' => '20',
);
if (isset($form_state['values']['productname']))
{
$form['productname']['#default_value'] = $form_state['values']['productname'];
}
//a "submit" button
$form['submit'] = array (
'#type' => 'submit',
'#value' => t('Add new Product'),
);
return $form;
}
You can use $form_state['storage'] in your submit handler to hoard values between steps. So add a submit function like so:
function addnewproduct_form_submit ($form, &$form_state) {
// Store values
$form_state['storage']['addnewproduct_productname'] = $form_state['values']['productname'];
// Rebuild the form
$form_state['rebuild'] = TRUE;
}
Then your form builder function would become:
function addnewproduct_form(&$form_state) {
$form = array();
$form['productname'] = array (
'#type' => 'textfield',
'#title' => t('Product Name'),
'#required' => TRUE,
'#size' => '20',
);
if (isset($form_state['storage']['addnewproduct_productname'])) {
$form['productname']['#default_value'] = $form_state['storage']['addnewproduct_productname'];
}
return $form;
}
Just remember that your form will keep being generated as long as your $form_state['storage'] is stuffed. So you will need to adjust your submit handler and unset($form_state['storage']) when are ready to save values to the database etc.
If your form is more like a filter ie. used for displaying rather than storing info, then you can get away with just
function addnewproduct_form_submit ($form, &$form_state) {
// Rebuild the form
$form_state['rebuild'] = TRUE;
}
When the form rebuilds it will have access to $form_state['values'] from the previous iteration.
Drupal will do this by default if you include:
$formproductname['#redirect'] = FALSE;
In your $formproductname array.
I prefer to save all values in one time when we are speaking about complex forms :
foreach ($form_state['values'] as $form_state_key => $form_state_value) {
$form_state['storage'][$form_state_key] = $form_state['values'][$form_state_value];
}
simply adding rebuilt = true will do the job:
$form_state['rebuild'] = TRUE;
version: Drupal 7
For anyone looking for an answer here while using webform (which I just struggled through), here's what I ended up doing:
//in hook_form_alter
$form['#submit'][] = custom_booking_form_submit;
function custom_booking_form_submit($form, &$form_state) {
// drupal_set_message("in form submit");
// dpm($form_state, 'form_state');
foreach ($form_state['values']['submitted_tree'] as $form_state_key => $form_state_value) {
$form_state['storage'][$form_state_key] = $form_state_value;
}
}
Note: added the ' as it was lost
In my case I had a couple of drop-downs. Submitting the form posted back to the same page, where I could filter a view and I wanted to show the previously selected options. On submitting the form I built a query string in the submit hook:
function myform_submit($form, &$form_state) {
$CourseCat = $form_state['values']['coursecat'];
drupal_goto("courses" , array('query' =>
array('cat'=>$CourseCat))
);
}
In the form build hook, all I did was get the current query string and used those as default values, like so:
function myform_form($form, &$form_state) {
$Params = drupal_get_query_parameters ();
$CatTree = taxonomy_get_tree(taxonomy_vocabulary_machine_name_load ('category')->vid);
$Options = array ();
$Options ['all'] = 'Select Category';
foreach ($CatTree as $term) {
$Options [$term->tid] = $term->name;
}
$form['cat'] = array(
'#type' => 'select',
'#default_value' => $Params['cat'],
'#options' => $Options
);
$form['submit'] = array(
'#type' => 'submit',
'#default_value' => 'all',
'#value' => t('Filter'),
);
return $form;
}
I usually solve this by putting the submitted value in the $_SESSION variable in the submit hook. Then the next time the form is loaded, I check the $_SESSION variable for the appropriate key, and put the value into the #default_value slot if there's anything present.
Not sure if this would work for you, but you could try adding the #default_value key to the form array
$form['productname'] = array (
'#type' => 'textfield',
'#title' => t('Product Name'),
'#required' => TRUE,
'#size' => '20',
'#default_value' => variable_get('productname', ''),
);
That way if the variable is set it will grab whatever it is, but if not you can use a default value.
