naming a file after submitting a form in Symfony - php

Question

I am working on a form which accepts some user input and an image file, the submission part and the data getting entered into the database is working fine but I am stuck at how to name a file once it is uploaded, right now this is what i see as an image name in database C:\wamp2.5\tmp\phpF360.tmp which obviously is not correct.
This is what my controller looks like DefaultController.php
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',
'Success'
);
}
return $this->render('BlogBundle:Default:blog-create.html.twig', array(
'form' => $form->createView()
)
);
}
This is what my upload() looks like inside Entity/Post.php which is uploading the file and moving it into the folder, the file name that I see in a folder is correct however now the one that goes into the database
public function upload()
{
if (null === $this->getImage()) {
return;
}
// I might be wrong, but I feel it is here that i need to name the file
$this->getImage()->move(
$this->getUploadRootDir(),
$this->getImage()->getClientOriginalName()
);
$this->path = $this->getUploadDir();
$this->file = null;
}
I will really appreciate if someone can push me in right direction, I just need to name the file, a name which gets assigned to the image in database and the file should get uploaded with the same name as well.
UPDATE
I managed to get it to work using the following function, not sure if this is the best practice but it did work, i would love to hear from others on this. please do not provide any links, if you can refine what has already been done that would be great.
public function upload()
{
// the file property can be empty if the field is not required
if (null === $this->getImage()) {
return;
}
$dirpath = $this->getUploadRootDir();
$image = $this->getImage()->getClientOriginalName();
$ext = $this->getImage()->guessExtension();
$name = substr($image, 0, - strlen($ext));
$i = 1;
while(file_exists($dirpath . '/' . $image)) {
$image = $name . '-' . $i .'.'. $ext;
$i++;
}
$this->getImage()->move($dirpath,$image);
$this->image = $image;
$this->path = $this->getUploadDir();
$this->file = null;
}

This topic from documentation may help you : http://symfony.com/doc/current/cookbook/doctrine/file_uploads.html
In addition, you should not put your upload function in the controller but rather use Doctrine events (Lifecycle callbacks) to call your function automatically.

Answer 2

as per suggestion of #theofabry you can check symfony2 documentation How to handle File Uploads with Doctrine, Controller must be thin as much as possible and try to do upload with Doctrine Events.
If you want to continue with your logic you may try following code, I have not tested yet...so please be careful.
// set the path property to the filename where you'ved saved the file
$this->path = $this->file->getClientOriginalName();
instead of
$this->path = $this->getUploadDir();
