I have read questions concerning this topic and also seen responses that have been of importance thus far, but am currently experiencing some programming difficulties related to this same issue. I am trying to upload multiple files using the Symfony 3 framework and it's been a challenge really. I have the following code for doing this; The first is the Form Type am using:
class ProductImageType extends AbstractType
{
/**
* Build the form
* @param None
* @return void
**/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('file', FileType::class, array('attr'=>array('class'=>'form-control'), 'multiple' => true));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(
array(
'data_class' => 'AppBundle\Entity\ProductImages',
)
);
}
public function getName()
{
return 'ProductImageType';
}
}
This is the Entity Am using:
class ProductImages
{
/**
* @var int
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="productSku", type="string", length=15, unique=true)
*/
private $productSku;
/**
* @var string $file
*
* @ORM\Column(name="file", type="string", length=255)
* @Assert\NotBlank(message="You must select at least one valid image file.")
*
*/
private $file;
/**
* @var int
*
* @ORM\Column(name="dateCreated", type="integer", nullable=true)
*/
private $dateCreated;
/**
* Get id
*
* @return int
*/
public function getId()
{
return $this->id;
}
/**
* Set productSku
*
* @param string $productSku
*
* @return productImages
*/
public function setProductSku($productSku)
{
$this->productSku = $productSku;
return $this;
}
/**
* Get productSku
*
* @return string
*/
public function getProductSku()
{
return $this->productSku;
}
/**
* Set images
*
* @param UploadedFile $file
*
* @return productImages
*/
public function setFile($file = null)
{
$this->file = $file;
return $this;
}
/**
* Get images
*
* @return string
*/
public function getFile()
{
return $this->file;
}
/**
* Set dateCreated
*
* @param integer $dateCreated
*
* @return productImages
*/
public function setDateCreated($dateCreated)
{
$this->dateCreated = $dateCreated;
return $this;
}
/**
* Get dateCreated
*
* @return int
*/
public function getDateCreated()
{
return $this->dateCreated;
}
}
And this is the controller am using to handle the file upload:
public function uploadAction(Request $request)
{
$files = $request->files->get('product_image');
$sku = $request->request->get('productSku');
$uploaded = false;
$message = null;
$count = 0;
$image_files = [];
$uploadDir = $this->getParameter('products_images_directory') . DIRECTORY_SEPARATOR . $sku . DIRECTORY_SEPARATOR;
$mimeTypes = array('image/jpeg','image/jpg','image/png','image/gif','image/bmp');
$doctrine = $this->getDoctrine()->getManager();
if(!empty($files))
{
foreach($files as $file => $v)
{
$filename[$count] = $sku . '_' . $count . '.' . $v[$count]->guessExtension();
$image_files[$count]['file'] = $filename[$count];
$image_files[$count]['file_size'] = $v[$count]->getClientSize();
Dump($image_files);die;
/**if(!is_dir($uploadDir) && !file_exists($uploadDir . $filename))
{
mkdir($uploadDir, 0775, TRUE);
if($value[$count]->move($uploadDir, $filename))
{
$productImages = new ProductImages();
$productImages->setProductSku($sku);
$productImages->setFile($filename[$i]);
$productImages->setDateCreated(strtotime(date('y-m-d h:i:s a')));
$doctrine->persist($productImages);
$doctrine->flush();
}
}
**/
$count++;
}
Dump($image_files);die('Action ended!');
if($count>1)
{
$uploaded = TRUE;
$message = "All Images have been uploaded & saved!!";
}
}
Dump($message);die;
return (new JsonResponse(
[
'uploaded'=>$uploaded,
'message'=>$message
]
));
}
I was going to use Dropzone.js to handle the front-end, i had to make sure everything works fine before integrating it. I discovered that when I try uploading multiple images using the foreach(...) only one of the images gets uploaded. on Dump(...) of the content of $request->request->get(...) i see the multiple files that were selected, but the foreach(...) only fetches the content of the first array not the second or third... I know the problem is within this condition, but i can't figure it out. Does someone have the sixth eye to assist, please?????
