symfony3 image is not uploaded - image-uploading

Question

In AppBundle\Etity\Image I have:
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity
* #ORM\Table(name="images")
* #ORM\HasLifecycleCallbacks
*/
class Image
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(type="string", length=255)
* #Assert\NotBlank
*/
private $name;
/**
* #ORM\Column(type="string", length=255, nullable=true)
* #Assert\NotBlank
*/
private $path;
/**
* #Assert\Image(maxSize="10M", mimeTypes="image/jpeg", minWidth = 600, minHeight = 400)
* #Assert\NotBlank
*/
private $file;
/**
* #ORM\Column(type="string", length=255)
* #Assert\NotBlank
*/
private $alt;
private $temp;
/**
* #return mixed
*/
public function getId()
{
return $this->id;
}
/**
* #return mixed
*/
public function getName()
{
return $this->name;
}
/**
* #param mixed $name
*/
public function setName($name)
{
$this->name = $name;
}
/**
* #return mixed
*/
public function getPath()
{
return $this->path;
}
/**
* #param mixed $path
*/
public function setPath($path)
{
$this->path = $path;
}
/**
* #return mixed
*/
public function getAlt()
{
return $this->alt;
}
/**
* #param mixed $alt
*/
public function setAlt($alt)
{
$this->alt = $alt;
}
public function getAbsolutePath()
{
return null === $this->path ? null : $this->getUploadRootDir() . '/' . $this->path;
}
public function getUploadRootDir()
{
return __DIR__ . '/../../../../web/' . $this->getUploadDir();
}
public function getUploadDir()
{
return 'images/full';
}
public function setFile(UploadedFile $file = null)
{
$this->file = $file;
// check if we have an old image path
if (isset($this->path)) {
// store the old name to delete after the update
$this->temp = $this->path;
$this->path = null;
} else {
$this->path = 'initial';
}
}
/**
* #return mixed
*/
public function getFile()
{
return $this->file;
}
/**
* #ORM\PrePersist()
* #ORM\PreUpdate()
*/
public function preUpload()
{
if (null !== $this->getFile()) {
// do whatever you want to generate a unique name
$filename = sha1(uniqid(mt_rand(), true));
$this->path = $filename.'.'.$this->getFile()->guessExtension();
}
}
/**
* #ORM\PostPersist()
* #ORM\PostUpdate()
*/
public function upload()
{
if (null === $this->getFile()) {
return;
}
// if there is an error when moving the file, an exception will
// be automatically thrown by move(). This will properly prevent
// the entity from being persisted to the database on error
$this->getFile()->move($this->getUploadRootDir(), $this->path);
// check if we have an old image
if (isset($this->temp)) {
// delete the old image
unlink($this->getUploadRootDir().'/'.$this->temp);
// clear the temp image path
$this->temp = null;
}
$this->file = null;
}
/**
* #ORM\PostRemove()
*/
public function removeUpload()
{
$file = $this->getAbsolutePath();
if ($file) {
unlink($file);
}
}
}
Which is used in AppBundle\Entity\Post.php like this:
/**
* #ORM\ManyToOne(targetEntity="Image", cascade="all")
* #ORM\JoinColumn(name="image_id", referencedColumnName="id")
*/
private $teaserImage;
In AppBundle\Form\Type\PostType.php I have this:
<?php
namespace AppBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use AppBundle\Entity\Post;
/**
* Defines the form used to create and manipulate blog posts.
*/
class PostType extends AbstractType
{
/**
* {#inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('title', null, array('label' => 'Title'))
->add('summary', null, array('label' => 'Summary'))
->add('teaserImage', 'AppBundle\Form\Type\ImageType', array('label' => 'Image'))
->add('content', null, array(
'attr' => array('rows' => 20),
'label' => 'Content',
))
;
}
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Post',
));
}
}
For some reason the images are not uploaded to the specified directory (or anywhere else) and I am not sure what I did wrong. I would be grateful for any insights.
Thank you.

Answer 1

The issue is related to
return __DIR__ . '/../../../../web/' . $this->getUploadDir();
In this case I changed the previous line to:
return __DIR__ . '/../../../web/' . $this->getUploadDir();
That is because my entity is located in src/AppBundle/Entity and to go to root directory it needs to hop 3 directories back.
Also it is a bad idea to hard-code paths in entities. I modified my example accordingly.
