Symfony maintaining relative path for file uploads - php

Question

I'm using Symfony 4.1, and I had a hard time getting the relative/fullpath to work as I want it.
In my database, I have a Customer entity with an attribute called photo.
<?php
namespace App\Entity;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity(repositoryClass="App\Entity\CustomerRepository")
* #ORM\Table("Customer")
*/
class Customer {
/**
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(type="string", nullable=true)
*
* #Assert\File(mimeTypes={ "image/png","image/jpeg" })
*/
private $photo;
public function getPhoto(): ?string
{
return $this->photo;
}
public function setPhoto(?string $photo): self
{
$this->photo = $photo;
return $this;
}
This makes sense and when I save the Customer with a Photo upload, it saves the photo in the database and on the filesystem as I expect.
In the database, the photo column will be set to something like '010925c8c427bddca9020197212b64af.png'
That's what I want, so it's all good.
The problem came up when I was trying to update an existing Customer entity. Customer->getPhoto() will return the relative path file name '010925c8c427bddca9020197212b64af.png.'
But the form doesn't pass validation, it says that this file doesn't exist.
$em = $this->getDoctrine()->getManager();
$custRepo = $em->getRepository('App:Customer');
$customer = $custRepo->findOneById($id);
$custForm = $this->createForm(CustomerType::class, $customer);
$custForm->handleRequest($request);
if ($custForm->isSubmitted() && $custForm->isValid()) {
$em->flush();
}
It fails because the validation doesn't look in the photos directory.
Here's my solution, which does work, but it seems too hackish. I wasn't wondering if someone had a more elegant approach to this.
$em = $this->getDoctrine()->getManager();
$custRepo = $em->getRepository('App:Customer');
$customer = $custRepo->findOneById($id);
$customer->setPhoto(new File($this->getParameter('photos_dir') .'/' . $customer->getPhoto()));
$custForm = $this->createForm(CustomerType::class, $customer);
$custForm->handleRequest($request);
if ($custForm->isSubmitted() && $custForm->isValid()) {
$photoPathParts = explode('/', $customer->getPhoto());
$customer->setPhoto(array_pop($photoPathParts));
$em->flush();
}
I'm getting the fullpath for the photo and updating the entity I'm currently work on. That gets the form validation to pass, but if I just save it, the path in the db is updated with the full path to the photo. That's not what I want, so I reset the photo to the relative path filename.
/**
* #ORM\Column(type="string", nullable=true)
*
* #Assert\File(mimeTypes={ "image/png","image/jpeg" })
*/
private $photo;

Look at this example how to upload image. The image is in a separate entity , you can relate it to customer OneToOne.
<?php
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
/**
* Image
*
* #ORM\Table(name="image")
* #ORM\Entity(repositoryClass="App\Repository\ImageRepository")
* #ORM\HasLifecycleCallbacks
*/
class Image
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(name="extension", type="string", length=180)
*/
private $name;
/**
* #Assert\Image()
*/
public $file;
private $tempFilename;
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
public function setFile(UploadedFile $file)
{
$this->file = $file;
if (null !== $this->extension) {
$this->tempFilename = $this->name;
$this->extension = null;
$this->name = null;
}
}
public function getFile()
{
return $this->file;
}
/**
* #ORM\PrePersist()
* #ORM\PreUpdate()
*/
public function preUpload()
{
if (null === $this->file) {
return;
}
$extension = $this->file->guessExtension();
$this->name = md5(uniqid('', true)) . '.' . $extension;
}
/**
* #ORM\PostPersist()
* #ORM\PostUpdate()
*/
public function upload()
{
if (null === $this->file) {
return;
}
if (null !== $this->tempFilename) {
$oldFile = $this->getUploadRootDir() . '/' . $this->tempFilename;
if (file_exists($oldFile)) {
unlink($oldFile);
}
}
$this->file->move($this->getUploadRootDir(), $this->name);
}
/**
* #ORM\PreRemove()
*/
public function preRemoveUpload()
{
$this->tempFilename = $this->getUploadRootDir() . '/' . $this->name;
}
/**
* #ORM\PostRemove()
*/
public function removeUpload()
{
if (file_exists($this->tempFilename)) {
unlink($this->tempFilename);
}
}
//folder
public function getUploadDir()
{
return 'uploads/photos';
}
// path to folder web
protected function getUploadRootDir()
{
return __DIR__ . '/../../public/' . $this->getUploadDir();
}
public function getWebPath()
{
return $this->getUploadDir() . '/' . $this->getName();
}
}
ImageFormType
NB: You should use the public attribue $file in the formType
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('file', FileType::class, array(
'label'=> false,
))
;
}
