Question

I am trying to download & save a PDF file from an online resource. I have seen the cookbook chapter on the File Uploads and tried to modify the technique for my own use. I just can’t get this to work.

Controller Code:

namespace Acme\DemoBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

use Acme\DemoBundle\Entity\Shipment;

class WelcomeController extends Controller
{
    public function indexAction(Request $request)
    {
        echo $barcodeUrl  = "http://www.website.com/somefile.pdf";

        $Shipment = new Shipment();
        $Shipment->setBarcodeUrl($barcodeUrl);

        $em = $this->getDoctrine()->getEntityManager();
        $em->persist($Shipment);
        $em->flush(); 

        // Saving The File:
        $saveto = __DIR__.'/../../../../web/uploads/documents';
        $ch = curl_init($barcodeUrl);
        $fp = fopen($saveto,'wb');
        curl_setopt($ch, CURLOPT_FILE, $fp);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_exec($ch);
        curl_close($ch);
        fclose($fp); 

        return new Response('Created shipment and saved file");
    }

    protected function getUploadRootDir()
    {
        return __DIR__.'/../../../../web'.$this->getUploadDir();
    }

    protected function getUploadDir()
    {
        return 'uploads/documents';
    }
}

Every time I run the above code. It saves a file in the web folder, that has the path I have mentioned as it’s name. The file does not open, doesn’t even save with any extension.

Saved File: /../../../../web/home/webmuch/uploads in the web folder.

Not really a Symfony2 problem. You need to also pass a filename to fopen.
So should be something like this:

$fp = fopen(sprintf('%s/%s.%s', $saveto, sha1($barcodeUrl), 'pdf'),'wb');

Also I noticed you have getUploadRootDir() method that you’re not using, I’m assuming because it didn’t work for you – the reason is that you’re missing a slash in there

protected function getUploadRootDir()
{
    return __DIR__.'/../../../../web/'.$this->getUploadDir();
}

Last but not least, you can get web location with $this->container->getParameter('kernel.root_dir').'/../web'

so

protected function getUploadRootDir()
{
    return $this->container->getParameter('kernel.root_dir').'/../web/'.$this->getUploadDir();
}
