Recently I have been looking into Symfony framework and I am working on a task where I need to upload a file using a form. Once the form has been submitted I need to insert the user input along with image name and path in database using Symfony framework strictly (not standard PHP), the upload process also need to consider if the image already exist, and if yes, then rename it so it does not get over-written.
Although, the following code works, but I wanted to ask here if this is the right way to do it.
(DefaultController.php)
This is my controller in this the function createBlogAction() handles the form submission, if the form is valid this functions calls another function which resides in Entity/Post.php to upload the file
namespace ClickTeck\BlogBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use ClickTeck\BlogBundle\Entity\Post;
use ClickTeck\BlogBundle\Form\PostCreate;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\File\UploadedFile;
class DefaultController extends Controller
{
public function createBlogAction(Request $request)
{
$post = new Post();
$form = $this->createForm(new PostCreate(), $post);
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$post->upload();
$post->setDate(date_create(date('Y-m-d H:i:s')));
$post->setAuthor('ClickTeck');
$em->persist($post);
$em->flush();
$this->get('session')->getFlashBag()->add(
'notice',
'Thank you!'
);
}
return $this->render('BlogBundle:Default:blog-create.html.twig', array(
'form' => $form->createView()
)
);
}
(Post.php)
In this file the function upload() uploads the file, it is this function I need confirmation on if this is the right way/best practice to upload image using Symfony 2.5
namespace ClickTeck\BlogBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\UploadedFile;
