I have an array of images that I want to be able to add to/update/delete from in a Symfony 4 form.
To create a form for these images, I'm using a custom form with a FileType in it:
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('image', FileType::class, array(
'data_class' => null
))
;
}
I am then using a CollectionType filled with instances of the form described above to render a form for each of the images in the array, with 'allow_add' and 'allow_delete' so I can add/remove rows via JavaScript.
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder->add('imagesets', CollectionType::class, array(
'entry_type' => ImageType::class,
'entry_options' => array('label' => false),
'allow_add' => true,
'allow_delete' => true
));
}
This works fine for adding new images, but when updating existing images, the FileType element shouldn't be required, it should only be required for the new rows.
Question: How can I make the FileType NOT required for existing images, yet required for all the new rows?
(Note, I will be passing plain arrays to these form objects, not Doctrine entities.)
You should add an EventListener to your ImageType form and modify the required attribute if the object is not new (or not null). Have in mind that adding the second element with the same name as the previous to the form, replaces it.
$builder
->add('image', FileType::class, array(
'data_class' => null,
'required' => true,
))
;
$builder->addEventListener(FormEvents::PRE_SET_DATA, function (FormEvent $event) {
// get the form object
$form = $event->getForm();
// get the entity/object data
$image = $event->getData();
// if it is new, it will be null
if(null !== $image) {
// modify the input
$form->add('image', FileType::class, array(
'data_class' => null,
'required' => false,
))
;
});
}
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 use APC result caching in docrine, and have filter form with type entity in all website pages and want cache this, but when I add useResultCache() to method I get exception
Entities passed to the choice field must be managed
example
...->getQuery()->useResultCache(true, null, 'someindex')->getResult()
but all action without form with entity type work normally.
Any ideas?
Don't know if You've figured out how to do it, but here's how I've done it (spent half a day figuring this out).
/* in FormType.php */
public function buildForm(FormBuilderInterface $builder, array $options)
{
$items = $options['entity_repository']
->findItems()
->useResultCache(true, 3600, 'my_cache')
->getResult();
$choice_list = new ObjectChoiceList($items, 'name', array(), null, 'id');
$builder->add('item', 'entity', array(
'class' => 'MyBundle:Items',
'multiple' => true,
'expanded' => true,
'choice_list' => $choice_list,
));
}
I am creating a form in the following manner:
$form = $this->createFormBuilder($breed)
->add('species', 'entity', array(
'class' => 'BFPEduBundle:Item',
'property' => 'name',
'query_builder' => function(ItemRepository $er){
return $er->createQueryBuilder('i')
->where("i.type = 'species'")
->orderBy('i.name', 'ASC');
}))
->add('breed', 'text', array('required'=>true))
->add('size', 'textarea', array('required' => false))
->getForm()
How can I set a default value for the species listbox?
Thank you for your response, I apologise, I think I should rephrase my question. Once I have a value that I retrieve from the model, how do I set that value as SELECTED="yes" for the corresponding value in the species choice list?
So, that select option output from the TWIG view would appear like so:
<option value="174" selected="yes">Dog</option>
You can define the default value from the 'data' attribute. This is part of the Abstract "field" type (http://symfony.com/doc/2.0/reference/forms/types/field.html)
$form = $this->createFormBuilder()
->add('status', 'choice', array(
'choices' => array(
0 => 'Published',
1 => 'Draft'
),
'data' => 1
))
->getForm();
In this example, 'Draft' would be set as the default selected value.
If you use Cristian's solution, you'll need to inject the EntityManager into your FormType class. Here is a simplified example:
class EntityType extends AbstractType{
public function __construct($em) {
$this->em = $em;
}
public function buildForm(FormBuilderInterface $builder, array $options){
$builder
->add('MyEntity', 'entity', array(
'class' => 'AcmeDemoBundle:Entity',
'property' => 'name',
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('e')
->orderBy('e.name', 'ASC');
},
'data' => $this->em->getReference("AcmeDemoBundle:Entity", 3)
));
}
}
And your controller:
// ...
$form = $this->createForm(new EntityType($this->getDoctrine()->getManager()), $entity);
// ...
From Doctrine Docs:
The method EntityManager#getReference($entityName, $identifier) lets you obtain a reference to an entity for which the identifier is known, without loading that entity from the database. This is useful, for example, as a performance enhancement, when you want to establish an association to an entity for which you have the identifier.
the solution: for type entity use option "data" but value is a object. ie:
$em = $this->getDoctrine()->getEntityManager();
->add('sucursal', 'entity', array
(
'class' => 'TestGeneralBundle:Sucursal',
'property'=>'descripcion',
'label' => 'Sucursal',
'required' => false,
'data'=>$em->getReference("TestGeneralBundle:Sucursal",3)
))
I think you should simply use $breed->setSpecies($species), for instance in my form I have:
$m = new Member();
$m->setBirthDate(new \DateTime);
$form = $this->createForm(new MemberType, $m);
and that sets my default selection to the current date. Should work the same way for external entities...
If you want to pass in an array of Doctrine entities, try something like this (Symfony 3.0+):
protected $entities;
protected $selectedEntities;
public function __construct($entities = null, $selectedEntities = null)
{
$this->entities = $entities;
$this->selectedEntities = $selectedEntities;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('entities', 'entity', [
'class' => 'MyBundle:MyEntity',
'choices' => $this->entities,
'property' => 'id',
'multiple' => true,
'expanded' => true,
'data' => $this->selectedEntities,
]);
}
I don't think you should use the data option, because this does more than just setting a default value.
You're also overriding any data that's being passed to the form during creation. So basically, you're breaking
support for that feature. - Which might not matter when you're letting the user create data, but does matter when you
want to (someday) use the form for updating data.
See http://symfony.com/doc/current/reference/forms/types/choice.html#data
I believe it would be better to pass any default data during form creation. In the controller.
For example, you can pass in a class and define the default value in your class itself.
(when using the default Symfony\Bundle\FrameworkBundle\Controller\Controller)
$form = $this->createForm(AnimalType::class, [
'species' => 174 // this id might be substituted by an entity
]);
Or when using objects:
$dog = new Dog();
$dog->setSpecies(174); // this id might be substituted by an entity
$form = $this->createForm(AnimalType::class, $dog);
Even better when using a factory:
(where dog probably extends from animal)
$form = $this->createForm(AnimalType::class, DogFactory::create());
This will enable you to separate form structure and content from each other and make
your form reusable in more situations.
Or, use the preferred_choices option, but this has the side effect of moving the default option to the top of your form.
See: http://symfony.com/doc/current/reference/forms/types/choice.html#preferred-choices
$builder->add(
'species',
'entity',
[
'class' => 'BFPEduBundle:Item',
'property' => 'name',
'query_builder' => ...,
'preferred_choices' => [174] // this id might be substituted by an entity
]
);
I'm not sure what you are doing wrong here, when I build a form using form classes Symfony takes care of selecting the correct option in the list. Here's an example of one of my forms that works.
In the controller for the edit action:
$entity = $em->getRepository('FooBarBundle:CampaignEntity')->find($id);
if (!$entity) {
throw $this->createNotFoundException('Unable to find CampaignEntity entity.');
}
$editForm = $this->createForm(new CampaignEntityType(), $entity);
$deleteForm = $this->createDeleteForm($id);
return $this->render('FooBarBundle:CampaignEntity:edit.html.twig', array(
'entity' => $entity,
'edit_form' => $editForm->createView(),
'delete_form' => $deleteForm->createView(),
));
The campaign entity type class (src: Foo\BarBundle\Form\CampaignEntityType.php):
namespace Foo\BarBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
use Doctrine\ORM\EntityRepository;
class CampaignEntityType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('store', 'entity', array('class'=>'FooBarBundle:Store', 'property'=>'name', 'em'=>'my_non_default_em','required' => true, 'query_builder' => function(EntityRepository $er) {return $er->createQueryBuilder('s')->orderBy('s.name', 'ASC');}))
->add('reward');
}
public function getName()
{
return 'foo_barbundle_campaignentitytype';
}
}
From the docs:
public Form createNamed(string|FormTypeInterface $type, string $name, mixed $data = null, array $options = array())
mixed $data = null is the default options. So for example I have a field called status and I implemented it as so:
$default = array('Status' => 'pending');
$filter_form = $this->get('form.factory')->createNamedBuilder('filter', 'form', $default)
->add('Status', 'choice', array(
'choices' => array(
'' => 'Please Select...',
'rejected' => 'Rejected',
'incomplete' => 'Incomplete',
'pending' => 'Pending',
'approved' => 'Approved',
'validated' => 'Validated',
'processed' => 'Processed'
)
))->getForm();
Setting default choice for symfony2 radio button
$builder->add('range_options', 'choice', array(
'choices' => array('day'=>'Day', 'week'=>'Week', 'month'=>'Month'),
'data'=>'day', //set default value
'required'=>true,
'empty_data'=>null,
'multiple'=>false,
'expanded'=> true
))
The form should map the species->id value automatically to the selected entity select field. For example if your have a Breed entity that has a OnetoOne relationship with a Species entity in a join table called 'breed_species':
class Breed{
private $species;
/**
* #ORM\OneToOne(targetEntity="BreedSpecies", mappedBy="breed")
*/
private $breedSpecies;
public function getSpecies(){
return $breedSpecies->getSpecies();
}
private function getBreedSpecies(){
return $this->$breedSpecies;
}
}
The field 'species' in the form class should pick up the species->id value from the 'species' attribute object in the Breed class passed to the form.
Alternatively, you can explicitly set the value by explicitly passing the species entity into the form using SetData():
$breedForm = $this->createForm( new BreedForm(), $breed );
$species = $breed->getBreedSpecies()->getSpecies();
$breedForm->get('species')->setData( $species );
return $this->render( 'AcmeBundle:Computer:edit.html.twig'
, array( 'breed' => $breed
, 'breedForm' => $breedForm->createView()
)
);
You can either define the right default value into the model you want to edit with this form or you can specify an empty_data option so your code become:
$form = $this
->createFormBuilder($breed)
->add(
'species',
'entity',
array(
'class' => 'BFPEduBundle:Item',
'property' => 'name',
'empty_data' => 123,
'query_builder' => function(ItemRepository $er) {
return $er
->createQueryBuilder('i')
->where("i.type = 'species'")
->orderBy('i.name', 'ASC')
;
}
)
)
->add('breed', 'text', array('required'=>true))
->add('size', 'textarea', array('required' => false))
->getForm()
;
You can use "preferred_choices" and "push" the name you want to select to the top of the list. Then it will be selected by default.
'preferred_choices' => array(1), //1 is item number
