How to render the input with VichUploaderBundle? - php

Question

I've a trouble with the bundle VichUploaderBundle with Symfony 4.
I've follow a tutorial to make an upload with VichUploaderBundle to upload multiple files.
My problem is that the input form to upload the file is never render. But I don't see what it's wrong with my Type file.
In my MemberType who can find all fiels, I've
...
->add('member_files', CollectionType::class, [
'label' => 'Add a file',
'entry_type' => MemberFilesType::class,
'allow_add' => true,
'allow_delete' => true,
'prototype' => true
])
...
And my MemberFilesType is :
<?php
namespace App\Form;
use App\Entity\MemberFiles;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Vich\UploaderBundle\Form\Type\VichImageType;
class MemberFilesType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('imageFile', VichImageType::class, [
'required' => false,
'download_uri' => true,
'image_uri' => true
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => MemberFiles::class,
]);
}
}
Do you have an idea ?

Answer 1

If you are working with a Member with no MemberFiles yet (empty collection) then that is what is expected. There are no collection entries because there are none persisted, try adding a new MemberFiles to the Member before you create the form.
In your controller action:
if(empty($member->getMemberFiles())){
$member->addMemberFile(new MemberFiles());
}
$form = $this->createForm(MemberType::class, $member);
