I have an unsubscribe form, where the first field is a entity field, fetching my UnsubscribeType entities :
$builder
->add('type', 'entity', array(
'class' => 'Evo\SubscriptionBundle\Entity\UnsubscribeType',
'property' => 'name',
'label' => 'Choose process type',
'empty_value' => 'Choose an option',
'empty_data' => null,
'label_attr' => array(
'class' => 'control-label',
),
'attr' => array(
'class' => 'form-control',
),
))
this collection contains 2 entities, #1 and #2. I would like to remove entity #2 from the select field if a custom test about the authed user fails.
Let's say I'd to test $this->getUser()->getCustomField(). If it is false, then i would like to remove entity #2 from the select field containing my UnsubscribeType entities.
Any idea how to do that ?
Perhaps you could pass to the form builder the result of the test from you controller and then, either use 'property' => 'name' or 'choices => // fetch entity #1 here.
So, something like this
public function buildForm(FormBuilderInterface $builder, array $options)
{
if($options['customField'] === TRUE)
{
$builder
->add('type', 'entity', array(
'class' => 'Evo\SubscriptionBundle\Entity\UnsubscribeType',
'property' => 'name',
// ..
;
}
else
{
$builder
->add('type', 'entity', array(
'class' => 'Evo\SubscriptionBundle\Entity\UnsubscribeType',
'choices' => $options['customField'],
// ..
;
}
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
// ..
$resolver->setRequired(array(
'customField'
));
}
And in your controller:
$form = $this->get('form.factory')->create(new EntryType(), $entry, array(
'customField' => $this->getUser()->getCustomField()
));
with getCustomField() returning either true or the entity (or collection of entities) that you want populating your select field. My solution would involve changing the getCustomField method though, don't know if that would suit.

I have this form and I want to checked if one of the two fields (numberPlate or expirationDate) is filled.
This is my buildForm:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('type', ChoiceType::class, array(
'choices_as_values' => true,
'required' => true,
'label' => 'Tipo Veicolo',
'empty_data' => '',
'empty_value' => '',
'attr' => array('class'=> 'form-control select2'),
'choices' => array('Auto' => 'Auto', 'Moto' => 'Moto', 'Camper' => 'Camper' ,'Barca' => 'Barca')
))
->add('numberPlate', TextType::class, array(
'label' => 'Targa',
'required' => false,
'attr' => array(
'class'=> 'form-control',
'minlength' => 5,
'maxlength' => 7
)
))
->add('expirationDate', DateTimeType::class, array(
'label' => 'Scadenza',
'widget' => 'single_text',
'input' => 'datetime',
'format' => 'dd/MM/yyyy',
'attr' => array('class'=> 'form-control')
))
;
}
You can ensure one of the fields are not empty, by adding a callback constraint to your entity.
namespace App\Entity;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\Context\ExecutionContextInterface;
class YourModel
{
/**
* #Assert\Callback
*/
public function validate(ExecutionContextInterface $context)
{
if (!$this->numberPlate && !$this->expirationDate) {
$context->buildViolation('Targa or Scadenza is required')
//optionally display the error at the numberPlate field, omit to display at the top of the form errors
->atPath('numberPlate')
->addViolation()
;
}
}
}
Then update your Scadenza field as not required.
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
//...
->add('expirationDate', DateTimeType::class, array(
'label' => 'Scadenza',
'required' => false,
'widget' => 'single_text',
'input' => 'datetime',
'format' => 'dd/MM/yyyy',
'attr' => array('class'=> 'form-control')
))
;
}
When the form is submitted it will execute the YourModel::validate method, and if the numberPlate and expirationDate are empty, it will fail $form->isValid().
Be sure to clear your cache after making the changes, to refresh the annotations.
NOTE: This will apply to any/all forms this entity model is used in,
to separate the validation you will need to implement validation groups

And I would like to let appear a drop down menu with the pupils name as a value and the id as the key.
Something like this :
->add('eleve', 'choice', array(
'choices' => array(id of the pupil => name of the pupil),
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('eleve', 'entity', array(
'class' => 'WCSCantineBundle:Eleve'
))
->add('status', 'choice', array(
'choices' => array('0' => 'Non-Inscrit'),
'label' => false
))
->add('date', 'text', array(
'label' => false
))
->add('Ajouter', 'submit');
}
Thank you for your help.
->add('eleve', 'entity', array(
'class' => 'WCSCantineBundle:Eleve'
'choice_label' => 'pupilname',
))
here pupil name would be the name of the field in your Eleve entity
this would create a drop down menu with all the Eleve records loaded from the database, on submission the id of the selection would be submitted through the form

i have a little problem with form. I have made form class and i need form field which will be like radio or select. Choices for select i need to pull from DB of another form. Here is the code so pls tell me where is my problem and how to solve it.
I want to have option when i create POST to choose from available pages (their names) and store that so i know for each post to which page it belongs and for each page i do query and show posts for that page..
<?php
namespace AppBundle\AppForm;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use AppBundle\Entity\Page;
class PostForm extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name', 'text')
->add('content', 'textarea')
->add('visible', 'choice', array(
'choices' => array(
'Yes' => 1,
'No' => 0
)
))
->add('belongToPage', 'choice', array(
'choices' => array (
new Page()
// here i want to pull from class Page names of
//all pages stored and to present
// this names for options in form field
),
'choices_as_values' => true,
'choice_label' => 'getName'
//getName is function from class Page which returns name of page(s)
))
->add('save', 'submit', array('label' => 'Create Post'));
}
public function getName()
{
// TODO: Implement getName() method.
}
}
Why don't you use entity field type. It would be smth like this:
->add('belongToPage', 'entity', array(
'class' => 'Class\Namespace\Class',
'property' => 'name',
'label' => 'choice_field_label'
))
If you need smth more complicated then just findAll for this field, you could use query_builder option:
->add('belongToPage', 'entity', array(
'class' => 'Class\Namespace\Class',
'property' => 'name',
'label' => 'choice_field_label',
'query_builder' => function(EntityRepository $er) {
return $er->findAllPagesForPostForm();
//Where findAllPagesForPostForm is the name of method in your
// pagesRepo which returns queryBuilder,
//instead of this you could just write your custom query like
//$qb = $er->createQueryBuilder('p');
//$qb->andWhere(...);
//return $qb;
}
))
I have an entity for support tickets: SupportTicket(). I also have an entry for replies to each ticket: SupportEntry(). I setup a one-to-many relationship between SupportTicket() and SupportEntry().
Now what I'm trying to do is build my form so that it creates the initial SupportTicket and then inserts the first SupportEntry, all in the same form. I've been messing around with my code for a while, only half-understanding what I'm doing, but this is where I'm at right now:
// My controller, creating the form
$supportTicket = new SupportTicket();
$form = $this->createFormBuilder($supportTicket)
->add('subject', 'text', array(
'label' => 'Subject'
))
->add('jobNumber', 'text', array(
'label' => 'Job Number'
))
->add('supportGroup', 'entity', array(
'label' => 'Group',
'class' => 'ShawmutClientBundle:SupportGroup',
'property' => 'name',
'multiple' => true,
'expanded' => true
))
// ->add('supportEntries', new SupportEntryType())
->add('supportEntries', new SupportEntryType())
->add('Save', 'submit')
->getForm();
My attempt at the custom form type
<?php
namespace Shawmut\ClientBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class SupportEntryType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('comment', 'textarea');
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Shawmut\ClientBundle\Entity\SupportEntry',
));
}
public function getName()
{
return 'SupportEntryType';
}
}
The form does have the comment box that I've pulled in from the form type, but when I try to submit the form, I get this error:
Neither the property "supportEntries" nor one of the methods "setSupportEntries()", "_set()" or "_call()" exist and have public access in class "Me\MyBundle\Entity\SupportTicket".
And yeah, that makes sense. It should be the addSupportEntries() method which is there. So how do I tell the form builder to use addSupportEntries instead of setSupportEntries?
Thanks in advance
Give the collection form type a go.
->add(
'supportEntries',
'collection',
array(
'type' => new SupportEntryType(),
'label' => 'Support Entries',
'error_bubbling' => true,
'cascade_validation' => true,
)
)
If you are using the collection form type, and the textarea is not showing, add:
'allow_add' => true
to the properties array().
The code would look something like this:
->add(
'supportEntries',
'collection',
array(
'type' => new SupportEntryType(),
'label' => 'Support Entries',
'error_bubbling' => true,
'allow_add' => true
'cascade_validation' => true,
)
)
To show the widget, assuming you are using twig:
{{ form_widget(form.supportEntries.vars.prototype.comment) }}
For saving the support entry, depending on how you built your entities, you might need to make some extra modifications.
The documentation should help you get it right:
How to Embed a Collection of Forms
I'm using Symfony2 form component to create and modify forms. I'm currently loading all model entities as choices, but I need to get only the Models related to the selected (posted) value from manufacturer.
How can I achieve this?
class VehicleType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('manufacturer', 'entity', array(
'label' => 'Brand',
'attr' => array('class' => 'input-block-level'),
'class' => 'BalslevCarBundle:Manufacturers',
'property' => 'short_name',
'empty_value' => 'All',
'required' => false
));
$builder->add('model', 'entity', array(
'label' => 'Model',
'class' => 'BalslevCarBundle:Models',
'property' => 'model',
'empty_value' => 'All',
'required' => false
));
}
public function getName()
{
return 'search';
}
}
First of all, you have to create "dynamically" your choices based onto user selection.
There are two ways, strictly coupled with your application behaviour, that leads (in both cases) at the same "core" code; the difference is only the way you call it.
So, let's explain the two possibilities:
Select manufacturer "statically" and don't change it over the time of request: use data retrieved from your business logic
Select manufacturer "dinamically" and can change them over the time of request: replace your form at every request; new form will be provided by business logic
So, the HEART of your question is: how can I retrieve only associated entities?
Answer
Into your VehicleType.php (where entity, in this case, is VehicleType ?)
private $manufacturerId;
public function __construct($manufacturerId)
{
$this->manufacturerId = $manufacturerId;
}
public function BuildForm(FormBuilderInterface $builder)
{
$manufacturerId = $this->manufacturerId;
$manufacturerQuery = function(EntityRepository $repo) use ($manufacturerId ){
return $repo->createQueryBuilder('m')
->where('m.id = :id')
->setParameter('id',$manufacturerId );};
$builder->add('manufacturer', 'entity', array(
'label' => 'Brand',
'attr' => array('class' => 'input-block-level'),
'class' => 'BalslevCarBundle:Manufacturers',
'property' => 'short_name',
'empty_value' => 'All',
'required' => false,
'query_builder' => $manufacturerQuery;
));
$builder->add('model', 'entity', array(
'label' => 'Brand',
'attr' => array('class' => 'input-block-level'),
'class' => 'BalslevCarBundle:Manufacturers',
'property' => 'short_name',
'empty_value' => 'All',
'required' => false,
'query_builder' => $modelQuery;
));
}
As you can see, in this way we use a custom repository to get only entities that are suitable for our needs. Obviously I am writing my DQL query without knowing your DB structure: it's your task and responsibility to adapt it to your real situation.
Moreover, you have to create another query for model (called $modelQuery in my answer) to retrieve correct models based on selected $id
