I am developping web application to manage artwork (Oeuvre) with Symfony 6.4.5 and EasyAdmin 4.8 and I have created custom field based on natif EA CollectionField with custom type based on CollectionType with the same options like allowAdd, allowDelete...
In the custom field, I can get anywhere options values set on my CRUD controller but, il the custom type, all methodes get options values come form $resolver->setDefaults()
Part of my CRUD controller:
class OeuvreCrudController extends AbstractCrudController
{
...
public function configureFields(string $pageName): iterable
{
return [
TableField::new('oeuvreStockages')
->setEntryType(StockageCollectionType::class)
->allowAdd()
->allowDelete()
->hideOnIndex(),
];
}
...
}
My custom form type:
<?php
namespace App\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\EventListener\ResizeFormListener;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormInterface;
use Symfony\Component\Form\FormView;
use Symfony\Component\OptionsResolver\Options;
use Symfony\Component\OptionsResolver\OptionsResolver;
class TableType extends AbstractType
{
/**
* @return void
*/
public function configureOptions(OptionsResolver $resolver)
{
$entryOptionsNormalizer = static function (Options $options, $value) {
$value['block_name'] = 'entry';
return $value;
};
$resolver->setDefaults([
'allow_add' => false,
'allow_delete' => false,
'prototype' => true,
'prototype_data' => null,
'prototype_name' => '__name__',
'entry_type' => TextType::class,
'entry_options' => [],
'prototype_options' => [],
'delete_empty' => false,
'invalid_message' => 'The collection is invalid.'
]);
$resolver->setNormalizer('entry_options', $entryOptionsNormalizer);
$resolver->setAllowedTypes('delete_empty', ['bool', 'callable']);
$resolver->setAllowedTypes('prototype_options', 'array');
}
/**
* @return void
*/
public function buildForm(FormBuilderInterface $builder, array $options): void
{
$resizePrototypeOptions = null;
if ($options['allow_add'] && $options['prototype']) {
$resizePrototypeOptions = array_replace($options['entry_options'], $options['prototype_options']);
$prototypeOptions = array_replace([
'required' => $options['required'],
'label' => $options['prototype_name'].'label__',
], $resizePrototypeOptions);
if (null !== $options['prototype_data']) {
$prototypeOptions['data'] = $options['prototype_data'];
}
$prototype = $builder->create($options['prototype_name'], $options['entry_type'], $prototypeOptions);
$builder->setAttribute('prototype', $prototype->getForm());
}
$resizeListener = new ResizeFormListener(
$options['entry_type'],
$options['entry_options'],
$options['allow_add'],
$options['allow_delete'],
$options['delete_empty'],
$resizePrototypeOptions
);
$builder->addEventSubscriber($resizeListener);
}
/**
* @return void
*/
public function buildView(FormView $view, FormInterface $form, array $options)
{
$view->vars = array_replace($view->vars, [
'allow_add' => $options['allow_add'],
'allow_delete' => $options['allow_delete'],
]);
if ($form->getConfig()->hasAttribute('prototype')) {
$prototype = $form->getConfig()->getAttribute('prototype');
$view->vars['prototype'] = $prototype->setParent($form)->createView($view);
}
}
/**
* @return void
*/
public function finishView(FormView $view, FormInterface $form, array $options)
{
$prefixOffset = -2;
// check if the entry type also defines a block prefix
/** @var FormInterface $entry */
foreach ($form as $entry) {
if ($entry->getConfig()->getOption('block_prefix')) {
--$prefixOffset;
}
break;
}
foreach ($view as $entryView) {
array_splice($entryView->vars['block_prefixes'], $prefixOffset, 0, 'collection_entry');
}
/** @var FormInterface $prototype */
if ($prototype = $form->getConfig()->getAttribute('prototype')) {
if ($view->vars['prototype']->vars['multipart']) {
$view->vars['multipart'] = true;
}
if ($prefixOffset > -3 && $prototype->getConfig()->getOption('block_prefix')) {
--$prefixOffset;
}
array_splice($view->vars['prototype']->vars['block_prefixes'], $prefixOffset, 0, 'collection_entry');
}
}
public function getBlockPrefix(): string
{
return 'table';
}
}
If I set 'allow_add' => true directly in the custom type, the view show allow add button.
$resolver->setDefaults([
'allow_add' => true,
'allow_delete' => false,
'prototype' => true,
'prototype_data' => null,
'prototype_name' => '__name__',
'entry_type' => TextType::class,
'entry_options' => [],
'prototype_options' => [],
'delete_empty' => false,
'invalid_message' => 'The collection is invalid.'
]);
