So I think I have done everything in order to server images and am unable to see an image even though I have followed the instructions precisely on this site:

http://jwage.com/2010/07/27/storing-files-with-mongodb-gridfs/

When I do: 

 $dm = $this->get('doctrine.odm.mongodb.document_manager');

         $image = $dm->createQueryBuilder('MyBundle:Image')
                     ->field('id')->equals($imageID) //I have verified imageID to be correct
                     ->getQuery()
                     ->getSingleResult();
                     var_dump($image->getFile()->getBytes());

I get:

string(194992) ""

Which tells me that the image is there, just that I am unable to get the bytes using the following as that comes null:

echo $image->getFile()->getBytes();

Please note that I am able to see the image using RockMongo etc so I know image is stored properly plus I can see it in the database stored as chucks. So what is wrong???

UPDATE: I HAVE ATTACHED THE VAR_DUMP OF THE file object.

  • How are you actually serving the images to the browser? Have you tried saving the image to a file first to confirm it can be retrieved OK? – Stennie Aug 24 '12 at 02:39
  • yes I have saved the images using persist and they appear in database – Strong Like Bull Aug 24 '12 at 05:27
  • So how are the images being served to the browser .. do you have a code example for that, since it seems to be the issue? – Stennie Aug 24 '12 at 05:40
