I create a form for a collection type of data in a separated from my controller
its my controller
/**
* #Security("has_role('ROLE_USER')")
* #Route("/phonebook/add", name="add")
*/
public function addPerson()
{
$person = new PhoneBookP();
$form = $this->createForm(PersoanlBookType::class, $person);
return $this->render(
'default/add.html.twig',
array('form' => $form->createView())
);
}
and its my form
->add('emails', CollectionType::class, array(
'entry_type' => EmailType::class,
'allow_add' => true,
'prototype' => true,
'allow_delete' => true,
'attr' => [
'class' => "emails-collection",
],
))
and my twig is
{% block body %}
{{ form(form) }}
{% endblock %}
it has no error and work in any common field (like NumberType,..) but not render CollectionType in my output. I using Symfony 4. whats my wrong?
in your rendering form you need to do this:
$person = new PhoneBookP();
//addEmail() is the arraycollection in your PhoneBookP Entity
//to be able to load the form, you need to add one from your arraycollection
$person->addEmail(new Email());
$form = $this->createForm(PersoanlBookType::class, $person);
The tags form_start and form_end only render the <form>-tags. To render the rest of the form elements call the form-twig-helper inside the <form>-tags too:
{{ form_start(form) }}
{{form(form)}}
<button type="submit">Register!</button>
{{ form_end(form) }}

I'm a beginner with PHP and Symfony.
I'm trying to show each values of ring (which is entity) from database and trying to add checkbox at the end of the each ring.
My twig template only shows the checkbox in the first ring.
How do I show all the rings?
This is my controller:
public function testPage(Request $request) {
$ring = $this->ringRepository->customFindAll();
$jewel = $this->ringJewelRepository->customFindAll();
$custom = $this->customRingRepository->customFindAll();
$form = $this->createFormBuilder($ring)
->add('active', CheckboxType::class, [
'label'=>'Selection',
'required'=>false
])
->getForm();
$form->handleRequest($request);
return [
'rings'=>$ring,
'jewels'=>$jewel,
'custom' => $custom,
'form'=>$form->createView()
];
}
This is my Twig template:
{% for ring in rings %}
<div>
<div class="text-center">
<p>Ring Name: {{ ring.ring_name }}</p>
<p>Ring Type: {{ ring.ring_type }}</p>
{{ form_start(form) }}
{{ form_widget(form.active) }}
{{ form_end(form) }}
</div>
<div class="text-center">
Update Ring
</div>
</div>
{% endfor %}
Considering your use-case I think you might be looking for an EntityType, with the 'multiple' option set to true. The syntax would be as below. Make sure to import your Ring class as well.
->add('active', EntityType::class, [
'class' => Ring::class,
'multiple' => true,
'label' => 'Selection',
'required' => false,
'query_builder' => static fn (RingRepository $ringRepository) => $ringRepository->customFindAll(),
]);
You can read more about the EntityType in the symfony docs.
I’m trying to create several identical forms, but it turns out that the forms are the same, or rather their values are the same, thus only the value of the first form changes
foreach ($projectStages as $projectStage) {
$formStage = $this->createFormBuilder($projectStage)
->add('status', ChoiceType::class,
[
'choices' => [
'active' => true,
'not active' => false,
]
])
->add('save', SubmitType::class, array('label' => 'Set active ' . $projectStage->getTitle()));
$forms[$projectStage->getId()] = $formStage->getForm();
$forms[$projectStage->getId()]->handleRequest($request);
if ($forms[$projectStage->getId()]->isSubmitted()) {
$em->flush();
return $this->redirect('/update-project/' . $id);
}
$forms[$projectStage->getId()] = $forms[$projectStage->getId()]->createView();
}
in twig i did this
{% for formStage in formStages %}
{{ form_start(formStage) }}
{{ form_widget(formStage.status) }}
{{ form_end(formStage) }}
{% endfor %}

I have a symfony form that contains a long list of items with checkboxes. I have successfully made knp paginator work and now the form is split into pages. However, when I move between pages I lose the checked/unchecked status of the checkboxes. I am sure that this is probably quite easy but I cannot seem to work it out. I am not very experienced with php yet.
Here is my controller:
/**
* #Route("/addquestions/{quizid}", name="addquestions")
*/
public function add(Request $request, PaginatorInterface $paginator, $quizid)
{
$repository = $this->getDoctrine()->getRepository(Quiz::class);
$quiz = $repository->find($quizid);
$repository = $this->getDoctrine()->getRepository(Question::class);
$questions = $repository->findAll();
// Paginate the results of the query
$pagination = $paginator->paginate($questions, $request->query->getInt('page', 1), 3);
$form = $this->createForm(AddQuizQuestionType::class, $quiz, ["pagination" => $pagination]);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$questions = $form->get('question')->getData();
foreach ($questions as $question){
$quizquestion = new QuizQuestion();
$quizquestion->setQuestion($question);
$quiz->addQuizQuestion($quizquestion);
}
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($quiz);
$entityManager->flush();
return $this->redirectToRoute('homepage');
}
return $this->render('editquiz/addquestions.html.twig', [
'form' => $form->createView(),
'pagination' => $pagination,
]);
}
And my form - it uses the paginated query to display the items with a check box.
class AddQuizQuestionType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('question', EntityType::class, [
'expanded' => true,
'multiple' => true,
'class' => Question::class,
'mapped' => false,
'choices' => $options['pagination'],
])
->add('submit', SubmitType::class, [
'label' => 'Submit',
])
->setMethod('GET')
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Quiz::class,
'pagination' => null,
]);
}
}
and my template - it renders the checkboxes with images from the database.
{% extends 'base.html.twig' %}
{% block title %}CreatequizController{% endblock %}
{% block body %}
<h1>Create Quiz</h1>
{{ form_start(form) }}
{% for question in form.question %}
<h5>Question {{ question.vars.value }}</h5>
<div class="border mb-5">
<img src="{{ asset(question.vars.label) }}" alt=""/>
<div class="pl-3">
{{ form_widget(question) }}
</div>
</div>
{% endfor %}
<div class="navigation">{{ knp_pagination_render(pagination) }}</div>
{{ form_end(form) }}
{% endblock %}
I would like it so that when I jump between pages the checkboxes that I have selected remain checked.
Thank you in advance,
Martyn
I'm new to Symfony 4 and I'm trying to render a form with a ChoiceType Field with numeric choices in order to generate the exact Number of tags Chosen by the user.
This is my controller:
class ContactController extends AbstractController
{
/**
* #Route("/matrix", name="matrix")
*/
public function index(Request $request)
{
$contact = new Contact();
// i've already added some tags
$tag3 = new Tag();
$tag3->setName('tag3');
$contact->getTags()->add($tag3);
$tag4=new Tag();
$tag4->setName('ciao');
$contact->getTags()->add($tag4);
$form = $this->createForm(ContactType::class, $contact);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$contactFormData = $form->getData();
dump($contactFormData);
}
return $this->render('contact/index.html.twig', array(
//'our_form' => $form,
'form' => $form->createView(),
));
}
At this Point of my code, the form seems to be filled, I've checked with some dumps.
This is my twig
{% block body %}
<div>
{{ form_start(form) }}
{{ form_widget(form) }}
<ul class="tags" data-prototype="{{ form_widget(form.tags.vars.prototype)|e('html_attr') }}">
{% for tag in form.tags %}
<li> {{ form_row(tag.name) }}
</li>
{% endfor %}
</ul>
<input type="submit" value="Send" class="btn btn-success" />
{{ form_end(form) }}
</div>
{% endblock %}
It seems there's no visibility between this two Files, in fact, he is not able to enter into the for a loop. I've dumped some stuff and I've seen that tags have no children at this Point but it should.
class ContactType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('motto')
->add('expectations', ChoiceType::class, array(
'choices' => array(
'1' => '1',
'2' => '2',
'3' => '3',
'4' => '4',
'5' => '5',
),
));
$builder->add('tags', CollectionType::class, array(
'entry_type' => TagType::class,
'entry_options' => array('label' => false),
'allow_add' => true,
'by_reference' => false,
'mapped' => false,
));
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
// Configure your form options here
]);
}
}
I'm perplex about this code => $contact->getTags()->add($tag3);. It seems Tags to be an entity and Contact another one so your Contact entity should have adders/removers and/or setters/removers (event if cumulate both is not necessary).
So your entity should like:
class Contact
{
// ...
/** #var Collection */
protected $tag;
// ...
public function __construct()
{
$this->tags = new ArrayCollection();
}
// ...
public function addTag(Tag $tag)
{
$this->tags->add($tag);
}
public function removeTag(Tag $tag)
{
// ...
}
}
A good example to implement your case: How to Embed a Collection of Forms
Then i don't know what's your TagType form looks like but even if it's well develop your twig is not ok.
First form_widget(form) render the entire form
From Symfony Doc
Renders the HTML widget of a given field. If you apply this to an entire form or collection of fields, each underlying form row will be rendered.
So re-render the collection will have no effect. And even if your twig code is not te good one to render a collection.
I want to render a form which has multiple Entities of same Class.
I will display 2 fields, Price(type=text) and Enabled(type=checkbox).
I don't know how many I will have of those entities, so form will have to get them dynamically.
I have tried to do the following
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('price', 'text', array(
'label' => 'Price',
'required' => true
))
->add('enabled','checkbox',array(
'label' => 'Use this currency',
))
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Osiris\Entity\Pricing',
'csrf_protection' => false
));
}
public function getName()
{
return 'pricingtype';
}
And in my Controller I have created my form like this:
$pricingForm = $this->createFormBuilder($prices)
->add('items','collection',array(
'required' => false,
'prototype' => true,
'type' => new PricingType(),
))
->getForm()
;
In my twig I do:
{% for price in form_pricing %}
<h2>Price</h2>
<div class="row">{{ form_widget(price) }}</div>
{% endfor %}
However it comes only with h2 Prices and empty div with class=row. I feel like I am half way there, but I've no idea how to move on.
If someone knows how to get fields on submit as well, I will really appreciate it.
I found the solution,
the way I was creating the form in Controller was wrong!
I had to do the following:
$pricingForm = $this->createFormBuilder(array('prices'=>$prices))
->add('prices','collection',array(
'required' => true,
'allow_add' => true,
'type' => new PricingType(),
))
->getForm()
;
"allow_add => true" is necessary when working with collection, otherwise it will NOT add any of PricingType collection of entities to the form.
Then, because the form is built inside the controller "$this->createFormBuilder(array('prices'=>$prices))" , $prices array must be passed as an array with array keyname same as the one used in "->add('prices','collection',array(...)" , which is 'prices' so Symfony will know what to bind where. $prices is an array of Pricing objects array(0 => new Pricing()).
In my PricingType I have:
class PricingType extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('price', 'text', array(
'label' => false,
'required' => true
))
->add('enabled','checkbox',array(
'label' => 'Use this currency',
))
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'XXX\XXX\Entity\Pricing',
'csrf_protection' => false
));
}
public function getName()
{
return 'pricingtype';
}
}
Here I need to have control over label attribute. I could not find the way for it( if anyone knows please post how to). I override my twig template as follows:
On the top we need next line of code:
{% form_theme form_pricing _self %}
Then override row and widget as follows (it was a nightmare to debug):
{% block _form_prices_entry_row %}
{% spaceless %}
{{ form_widget(form) }}
{% endspaceless %}
{% endblock %}
{% block _form_prices_entry_widget %}
{% spaceless %}
{{ form_row(form.price, { 'label' : form.vars.value.getCurrency().getTitle() } ) }}
{{ form_row(form.enabled) }}
{% endspaceless %}
{% endblock %}
In the body then, render form elements as follows:
{% for price in form_pricing.prices %}
<div class="price-row">{{ form_row(price) }}</div>
{% endfor %}
I really hope this will help you guyz. It was a real nightmare to debug especially the twig file, I did it thanks to my clever colleague.
I think you have missed a for loop in your twig file
Check this example:
{# store the prototype on the data-prototype attribute #}
<ul id="email-fields-list" data-prototype="{{ form_widget(form.emails.vars.prototype)|e }}">
{% for emailField in form.emails %}
<li>
{{ form_errors(emailField) }}
{{ form_widget(emailField) }}
</li>
{% endfor %}
</ul>
See the loop, I think that you need to add in your twig file.
In addition to loops you need to add JavaScript also.
