Symfony3: "The file /tmp/php4k3bf8 could not be accessed"

Question

I am getting the error message "The file /tmp/php4k3bf8 could not be accessed" when uploading a file. See here the full error log.

[2017-08-13 15:50:29] request.INFO: Matched route "apply_for_job". {"route":"apply_for_job","route_parameters":{"_controller":"Vendor\\FinanceBundle\\Controller\\JobResponseController::createAction","job_id":"2850","_route":"apply_for_job"},"request_uri":"https://my.site.in/job-enrollment/open-position/2850/apply","method":"POST"} []

this is the entity that is used for form submission:

<?php

namespace Vendor\FinanceBundle\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Vich\UploaderBundle\Mapping\Annotation as Vich;

class RRFPreScreen
{

    /**

     */
    protected $id;

    ///
    /// ...
    ///

    /**

     *

     *
     * @var File $imageFile
     */
    protected $imageFile;

    /**
     * @ORM\Column(type="string", length=255, name="profile_image", nullable=true)
     *
     * @var string $imageName
     */
    protected $imageName;

    /**
     * @ORM\Column(type="datetime", name="updated_at", nullable=true)
     *
     * @var \DateTime $updatedAt
     */
    protected $updatedAt;

    public function __construct()
    {
        $this->created = new \DateTime('now');
    }

    /**

    public function setImageFile(File $image = null)
    {
        $this->imageFile = $image;

        if ($image) {
            // It is required that at least one field changes if you are using doctrine
            // otherwise the event listeners won't be called and the file is lost
            $this->updatedAt = new \DateTime('now');
        }
    }
}

and then the form type:

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $self = $this;
        $factory = $builder->getFormFactory();


        $builder->addEventListener(
            FormEvents::PRE_SET_DATA,
            function(FormEvent $event) use($self, $factory, $builder) {
                $form = $event->getForm();
                $preScreen = $event->getData();

                $form
                    ->add('firstName', TextType::class, array(

                        'label_attr' => array('data-note' => 'Please provide your name as displayed in your identity proof and expand all initials'),
                    ))

                        'label_attr' => array('class' => 'force-validation'),
                        'attr' => array('data-entry' => '1', 'data-max-entry' => '3', 'class' => 'suggested-rows col-sm-8')
                    ));
            }
        );

    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Vendor\FinanceBundle\Entity\RRFPreScreen',
        ));
    }

    public function getName() {
        return 'rrf_pre_screen1';
    }
}

I am quite sure that imageFile is causing the problem, as only after I added the property to the class the error came.

finaly the configuration for Vich in config.yml:

  vich_uploader:
  db_driver: orm

  mappings:

      profile_image_prescreen:
          uri_prefix:         /uploads/images-prescreen
          upload_destination: %kernel.root_dir%/data/uploads/images-prescreen

          inject_on_load:     false #should the file be injected into the uploadable entity when it is loaded from the data store
          delete_on_update:   true #should the file be deleted when a new file is uploaded
          delete_on_remove:   true #should the file be deleted when the entity is removed

Does anybody has an idea how this can be solved? The permissions on the /tmp folder are 777.

UPDATE:

I am running Ubuntu 14.04 and have root access to the server.

UPDATE 2

When running ls -la /tmp/, this is the output I get:

my_username@servername:~/suvya$ ls -la /tmp/

Answer 1

I am not sure but Below may be the issue from ls -la /tmp/ output.

my_username@servername:~/suvya$ ls -la /tmp/ total 4649812 drwxrwxrwt 6 root root 36864 Aug 17 07:44 .

It Seems like /tmp owner is root I guess It should be HTTP i.e. www-data

If this is the case then you can change tmp dir location from php.ini file and set to somewhere in your project say

upload_tmp_dir="your_project_base_path/tmp"
