Forms symfony2, display my created form in Symfony2 - symfony

i need your help please , I want to display my created form in Symfony2. I want to display my created form 92 times becouse i have 92 numbers in my database(every number is a form) , i didn't know how to do it here is my code:
controller:
class DefaultController extends Controller
{
public function QuestionsAction(Request $request)
{
$questions = $this->getDoctrine()->getEntityManager()
->getRepository('Tests\TestsPhpBundle\Entity\Question')
->findAll();
$task = new Question();
$forms = $this->createForm(new QuestionType(), $task);
if ($request->getMethod() == 'POST') {
$forms->bindRequest($request);
if ($forms->isValid())
{
$em = $this->getDoctrine()->getEntityManager();
$em->persist($task);
$em->flush();
}
}
{
return $this->render('TestsTestsPhpBundle:Default:index.html.twig', array(
'questions' => $questions,
'forms' => $forms->createView()
));
}
}
}
my form file:
class QuestionType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('categories', null, array('required' => false,
))
->add('text', 'entity', array(
'class' => 'TestsTestsPhpBundle:Question',
'query_builder' => function($repository) {
return $repository->createQueryBuilder('p')->orderBy('p.id', 'ASC'); },
'property' => 'text'))
;
}
public function getDefaultOptions(array $options)
{
return array(
'data_class' => 'Tests\TestsPhpBundle\Entity\Question',);
}
public function getName()
{
return 'question';
}
}
my twig file:
{% block content %}
<h2>Questions</h2>
{% for question in questions %}
<dl>
<dt>Number</dt>
<dd>{{ question.number }}<dd>
{% for form in forms %}
{{ form_row(forms.categories) }}
{{ form_row(forms.text) }}
</dl>
{% endfor %}
<hr />
{% endfor %}
{% endblock %}

I recommend to read capter: Embedding Controller
http://symfony.com/doc/2.0/book/templating.html
<div id="sidebar">
{% render "AcmeArticleBundle:Article:recentArticles" with {'max': 3} %}
</div>
You can make a for loop within Twig Template and call an action (with parameter if needed) where you render the form. -> QuestionsAction in your case.

How to fix 'Variable does not exist' when using FormBuilder?

I've worked through a few of the Forms-Tutorials on the Symfony-Page (especially How to Embed a Collection of Forms, How To use a Form without a Dataclass & CollectionType Field ).
I'm trying to show a form with multiple lead partners which can be edited and submitted back to the system.
But i get a Twig_Runtime_Error saying: ''Variable "lead_partners" does not exist''.
My Twig:
{% block content %}
<div>
{{ form_start(form) }}
{% for partner in lead_partners %}
{{ form_row(partner.name) }}
{% endfor %}
{{ form_end(form) }}
</div>
{% endblock content %}
My Controller Code:
public function overview(Request $request, \App\Utility\LeadPartnerLoader $LeadPartnerLoader)
{
$leadPartnerList = $LeadPartnerLoader->loadAll();
$form = $this->createFormBuilder($leadPartnerList)
->add('lead_partners', CollectionType::class, [
'entry_type' => LeadPartnerFormType::class,
])->getForm();
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid())
{
$data = $form->getData();
}
return $this->render(
'lead_partner_overview2.html.twig',
[
'form' => $form->createView()
]);
}
And the Form Type (LeadPartnerFormType):
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => LeadPartner::class,
));
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('id', HiddenType::class)
->add('name', TextType::class);
}
$leadPartnerList is of type array.
What am i doing wrong/missing here?
Kind Regards
It seems your action overview soesn't return the lead_partners variable you use in your template.
You can try to do this
return $this->render(
'lead_partner_overview2.html.twig',
[
'form' => $form->createView(),
'lead_partners' => $leadPartnerList, // I gess that's the list you want to loop ?
]);

Symfony function search wih query builder

I would like to create a function to search for a movie through the query builder
I have a table Movie:
1. Id
2. Titre
3. Content
And i have class MovieRepository :
class MovieRepository extends EntityRepository
{
public function myFindAll()
{
return $this->createQueryBuilder('a')
->getQuery()
->getResult();
}
public function getSearchMovies($movie){
$qb = $this->createQueryBuilder('m')
->where('m.title LIKE :title')
->setParameter('title', '%' . $movie->getTitle() . '%')
->orderBy('m.title', 'DESC')
->getQuery();
}
}
Also i have MovieController :
public function indexAction()
{
$movie = new Movie;
$form = $this->createForm(new SearchMovieType(), $movie);
$request = $this->getRequest();
if ($request->getMethod() == 'POST') {
$form->bind($request);
$movies = $this->getDoctrine()
->getManager()
->getRepository('AreaDownloadBundle:Movie')
->getSearchUsers($movie);
return $this->render('AreaDownloadBundle:Download:index.html.twig', array('form' => $form->createView(),array('movies' => $movies)));
} else {
$movies = $this->getDoctrine()
->getManager()
->getRepository('AreaDownloadBundle:Movie')
->myFindAll();
return $this->render('AreaDownloadBundle:Download:index.html.twig',array('form' => $form->createView(), 'movies' => $movies));
}
}
SearchMovieType :
class SearchMovieType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('title','text', array('required' => false, ))
;
}
And i have index.hml.twig, which can display movies with a search bar :
{% extends "::template.html.twig" %}
{% block body %}
<form action="{{ path('area_download_index') }}" method="post">
<div id="bar">
{{ form_widget(form.title) }}
<input type="submit" value="Chercher">
{{ form_rest(form) }}
</div>
</form>
{% for movie in movies %}
{{ movie.title }}
{{ movie.content }}
{% endfor %}
{% endblock %}
when I seized a title of a movie he sends me this error
Variable "movies" does not exist in AreaDownloadBundle:Download:index.html.twig at line 12
Instead of posting it as a comment, it should have been posted as an answer in the correct formatting; like so:
return $this->render(
'AreaDownloadBundle:Download:index.html.twig',
array(
'form' => $form->createView(),
'movies' => $movies
)
);
This definitely should fix the problem!

How to render collections of forms

I have problem with rendering forms in Twig. I'm trying to embed a collection of forms. When I render the collection, it is not shown, while it is shown the name of form. The aim was to make the forms with an add button to add at runtime the form for each element of the collection. I get a look to the Symfony Docs and I think I followed it step by step.
This is my controller:
function new_resultAction($id)
{
$em = $this->getDoctrine()->getEntityManager();
$test = $em->getRepository('LadelaOdeskTesterBundle:Test')->find($id);
$categories =
$em->getRepository('LadelaOdeskTesterBundle:Category')->findByTest($test);
if (!$test) {
throw $this->createNotFoundException('Unable to find Test entity.');
}
$resultCategory = new Category();
$form = $this->createForm(new CategoryType() , $resultCategory);
$request = $this->getRequest();
if ('POST' === $request->getMethod()) {
$form->bindRequest($request);
if ($form->isValid()) {
$em->persist($resultCategory);
$em->flush();
$this->get('session')->setFlash('success', 'New result Categories were
saved!');
return $this->redirect($this->generateUrl('questions', array(
'id' => $resultCategory->getId(),
)));
}
}
return array(
'test' => $test,
'categories' =>$categories,
'form' => $form->createView(),
);
}
My forms:
class ResultCategoryType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('value', 'integer');
$builder->add('category', 'entity', array(
'class' => 'Ladela\OdeskTesterBundle\Entity\Category',
'query_builder' => function ($repository) { return
$repository->createQueryBuilder('p')->orderBy('p.name', 'ASC'); },
'property' => 'name' ,
'expanded' => false ,
'multiple' => false , ));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Ladela\OdeskTesterBundle\Entity\ResultCategory'
));
}
public function getName()
{
return 'ResultCategory';
}
}
class CategoryType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
->add('resultCategories','collection', array(
'type' => new ResultCategoryType(),
'allow_add' => true,
'by_reference' => false,
'prototype' => true,
))
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Ladela\OdeskTesterBundle\Entity\Category'
));
}
public function getName()
{
return 'category';
}
}
And my twig file:
<form method="post" action="{{ path('questions',{'id': test.id }) }}" {{
form_enctype(form) }} >
<ul class="tags" data-prototype="{{
form_widget(form.resultCategories.vars.prototype)|e
}}">
{# iterate over each existing tag and render its only field: name #}
{% for ResultCategory in form.resultCategories %}
<li>{{ form_row(ResultCategory.category) }}</li>
{% endfor %}
Add a tag
</ul>
{{ form_rest(form) }}{# form.items's prototype is rendered twice #}
{{ form_errors(form) }}
<input type="submit" value ="add" />
</form>
{% block javascripts %}
<script type="text/javascript">
// Get the div that holds the collection of tags
var collectionHolder = $('ul.tags');
// setup an "add a tag" link
var $addTagLink = $('Add a tag');
var $newLinkLi = $('<li></li>').append($addTagLink);
jQuery(document).ready(function() {
// add the "add a tag" anchor and li to the tags ul
collectionHolder.append($newLinkLi);
$addTagLink.on('click', function(e) {
// prevent the link from creating a "#" on the URL
e.preventDefault();
// add a new tag form (see next code block)
addTagForm(collectionHolder, $newLinkLi);
});
});
// Get the div that holds the collection of tags
var collectionHolder = $('ul.tags');
// setup an "add a tag" link
var $addTagLink = $('Add a tag');
var $newLinkLi = $('<li></li>').append($addTagLink);
jQuery(document).ready(function() {
// add the "add a tag" anchor and li to the tags ul
collectionHolder.append($newLinkLi);
$addTagLink.on('click', function(e) {
// prevent the link from creating a "#" on the URL
e.preventDefault();
// add a new tag form (see next code block)
addTagForm(collectionHolder, $newLinkLi);
});
});
{% endblock %}
The collection of forms is not rendered since you don't initiate it! See the official docs. There are "dummy" tags object used to create the tag forms.

Render Individual Form Element in Symfony 2

I'm having trouble rendering individual form fields in a twig template from a Symfony 2 form. In the example below, I'm simply trying to render the first_name form field.
Also, form_errors never renders anything.
Here is my Form object:
namespace ABC\WebsiteBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class LoanApplication extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('first_name', 'text', array('required' => true));
}
public function getName()
{
return 'LoanApplication';
}
public function getDefaultOptions(array $options)
{
return array(
//'data_class' => 'Acme\TaskBundle\Entity\Task',
'csrf_protection' => true,
'csrf_field_name' => '_token',
// a unique key to help generate the secret token
'intention' => 'loan_application',
);
}
}
Here is the controller:
namespace ABC\WebsiteBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use JML\WebsiteBundle\Form\LoanApplication;
use JML\WebsiteBundle\QuickBase as QuickBase;
class ApplyController extends Controller
{
public function indexAction()
{
$form = $this->createForm(new LoanApplication());
return $this->render('ABCWebsiteBundle:Apply:index.html.twig', array(
'form' => $form->createView(),
));
if ($request->getMethod() == 'POST') {
$form->bindRequest($request);
if ($form->isValid()) {
// perform some action, such as saving the task to the database
//return $this->redirect($this->generateUrl('task_success'));
}
}
}
}
And the twig:
<form action="{{ path('apply') }}" method="post" {{ form_enctype(form) }}>
<pre>
{{ dump(form_errors(form)) }} // always empty
</pre>
<div>
{{ form_label(form.first_name) }} // this renders
{{ form_widget(form.first_name) }} //empty
{{ form_row(form.first_name) }} //empty
</div>
<input type="submit" formnovalidate/>
</form>

Error with entity field - Symfony2

This is my file:
<?php
namespace EM\ExpensesBundle\Entity;
use Symfony\Component\Form\FormBuilder;
use Symfony\Component\Form\AbstractType;
class ChooseCatType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder->add('name', 'entity', array(
'class' => 'EMMyFriendsBundle:Category',
'property' => 'name',
'empty_value' => 'All items',
'required' => false,
'query_builder' => function ($repository)
{ return $repository->createQueryBuilder('cat')
->select('cat')
->orderBy('cat.name', 'ASC');
}, ));
}
public function getName()
{
return 'choose_category';
}
}
Here I create the form:
namespace EM\ExpensesBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use EM\ExpensesBundle\Entity\Category;
use EM\ExpensesBundle\Entity\ChooseCatType;
class HomeController extends Controller
{
public function indexAction()
{
//Categories
$cat = new Category();
$dd_form = $this->createForm(new ChooseCatType(), $cat);
return $this->render('EMExpensesBundle:Home:index.html.twig', array(
'dd_form' => $dd_form->createView()));
}
}
and template:
{% extends "::base.html.twig" %}
{% block title %}
Expenses
{% endblock %}
{% block body %}
<div class="content">
<p> Choose category: </p>
<form class="cat" action="" method="post" {{ form_enctype(dd_form) }}>
{{ form_widget(dd_form.name) }}
{{ form_rest(dd_form) }}
<input type="submit" value="Show items" />
</form>
Manage Categories
</div>
{% endblock %}
but I get an error:
Fatal error: Declaration of EM\ExpensesBundle\Entity\ChooseCatType::buildForm()
must be compatible with that
of Symfony\Component\Form\FormTypeInterface::buildForm()
in C:\xampp\htdocs\Expenses\src\EM\ExpensesBundle\Entity\ChooseCatType.php
on line 9
Any ideas?
Use FormBuilderInterface in your method signature:
public function buildForm(FormBuilderInterface $builder, array $options)
