I'm trying to do file upload for my Task entity. I working with two sources: http://symfony.com/doc/3.4/controller/upload_file.html and Symfony2 file upload step by step but I can't figure out how to keep uploaded file during editing.
I'm not sure if I implemented right the part:
My form was complaining when I tried to edit any Task:
The form's view data is expected to be an instance of class Symfony\Component\HttpFoundation\File\File, but is a(n) string. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms a(n) string to an instance of Symfony\Component\HttpFoundation\File\File.
So I modified getter getBrochure() in my Task entity which I want to expand of PDF file. Please, see below my getBrochure method This is code of my entity:
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\HttpFoundation\File\File;
/**
* Task
*
* @ORM\Table(name="task")
* @ORM\Entity(repositoryClass="AppBundle\Repository\TaskRepository")
*/
class Task
{
/**
* @var int
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* @var \DateTime
*
* @ORM\Column(name="datetime", type="datetime")
*/
private $datetime;
/**
* @ORM\ManyToMany(targetEntity="Category", inversedBy="tasks")
* @ORM\JoinTable(name="categories_tasks")
*/
private $categories;
/**
* @ORM\Column(type="text")
*/
private $description;
/**
* @ORM\Column(type="string")
*
* @Assert\File(mimeTypes={ "application/pdf" })
*/
private $brochure;
public function __construct() {
$this->categories = new \Doctrine\Common\Collections\ArrayCollection();
}
/**
* Get id
*
* @return int
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* @param string $name
*
* @return Task
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Set datetime
*
* @param \DateTime $datetime
*
* @return Task
*/
public function setDatetime($datetime)
{
$this->datetime = $datetime;
return $this;
}
/**
* Get datetime
*
* @return \DateTime
*/
public function getDatetime()
{
return $this->datetime;
}
public function getCategories()
{
return $this->categories;
}
public function setCategories(Category $categories)
{
$this->categories = $categories;
}
public function getDescription()
{
return $this->description;
}
public function setDescription($description)
{
$this->description = $description;
}
public function getBrochure()
{
//return $this->brochure;
return new File($this->brochure);
}
public function setBrochure($brochure)
{
$this->brochure = $brochure;
return $this;
}
public function __toString() {
return $this->name;
}
}
?>
The result is that I can load edit page, but the field of file upload is empty, there is no information that I uploaded any file. I'm not sure if there should be any information but I see in database that the filename is there and also in web folder there is uploaded file. When I change anything in Task and save of file is cleared and when I try to launch edit page I see:
The file "" does not exis
What is clear for me, because file column for this Task was cleared. So, how to keep file during editing when I don't want to upload new file?
This is my TaskType
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Ivory\CKEditorBundle\Form\Type\CKEditorType;
use Symfony\Component\Form\Extension\Core\Type\FileType;
class TaskType extends AbstractType
{
/**
* {@inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('name')->add('datetime')->add('categories')
->add('description', 'Ivory\CKEditorBundle\Form\Type\CKEditorType', array())
->add('brochure', FileType::class, array('label' => 'Broszurka (PDF)', 'required' => false));
}
/**
* {@inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Task'
));
}
/**
* {@inheritdoc}
*/
public function getBlockPrefix()
{
return 'appbundle_task';
}
}
and this is my TaskController (only edit action)
/**
* Displays a form to edit an existing task entity.
*
* @Route("/{id}/edit", name="task_edit")
* @Method({"GET", "POST"})
*/
public function editAction(Request $request, Task $task)
{
$deleteForm = $this->createDeleteForm($task);
$editForm = $this->createForm('AppBundle\Form\TaskType', $task);
$editForm->handleRequest($request);
if ($editForm->isSubmitted() && $editForm->isValid()) {
$this->getDoctrine()->getManager()->flush();
return $this->redirectToRoute('task_edit', array('id' => $task->getId()));
}
return $this->render('task/edit.html.twig', array(
'task' => $task,
'edit_form' => $editForm->createView(),
'delete_form' => $deleteForm->createView(),
));
}
