Symfony

Yes, there is currently no documentation on how to upload a file in Symfony2. Yes, it took me hours to figure out how to do it. Yes, of course I will share!
I don’t think this is the correct Symfony way to do it, but it works and I believe it is secure. I would like to access the $uploadedFile object from the $form object instead of the $request. If you know how to do it, please write a comment.

The code is pretty straight forward and documented so I figure I just post it.

My controller:

public function indexAction()
{
    //create a simple form with one filed called "dataFile" of type "file"
    $form = $this->get('form.factory')
	 ->createBuilder('form')
	 ->add("dataFile","file", array("required"=>true))
	 ->getForm();

    $request = $this->get('request');
    if ($request->getMethod() == 'POST') {
        //bind the request, (note the enctype in the template)
      	$form->bindRequest($request); 

    	if ($form->isValid()) {
            //if the form is valid, try to get the uploaded file object
            //Symfony\Component\HttpFoundation\File\UploadedFile
    	    $files=$request->files->get($form->getName());
    	    $uploadedFile=$files["dataFile"]["file"]; //"dataFile" is the name on the field

            //once you have the uploadedFile object there is some sweet functions you can run
    	    $uploadedFile->getPath();//returns current (temporary) path
    	    $uploadedFile->getOriginalName();
    	    $uploadedFile->getMimeType();

            //and most important is move(),
    	    $uploadedFile->move(
    	        $_SERVER['DOCUMENT_ROOT']."/uploads",
    	        $uploadedFile->getOriginalName()
    	    );

    	    $this->get('session')->setFlash('notice', 'The file is uploaded!');
    	}
    	else{
    		//form is not valid

    	}
    }//end if request method == POST	

    return $this->render('ApplicationMyBundle:Default:index.html.twig',
        array("form"=>$form->createView()));
    }

My template:

{# note the form_enctype, without it the form will not bind in the controller #}
<form action="" method="post" {{ form_enctype(form) }}>
{{ form_widget(form) }}
<input type="submit" class="submit" id="form_submit" value="Save" />
</form>

När man utvecklar i PHP så vet man att det lätt kan bli lite kladdigt. Man importerar saker hit och dit och snart har man ingen koll på vad som gör vad eller vilken fil som används när. Många skickliga utvecklare har ett eget litet system när man utvecklar en ny applikation. Man har vissa mappar och vissa regler. Men när en annan eller en tredje utvecklare kommer in i projektet så blir det bara kaos.

Ett par franska utvecklare har skrivit PHP ramverket Symfony. Det är tokigt objektorienterat och det gör många av programmerarens simpla autonoma uppgifter automatiskt. Till exempel skapa databasklasser, skriva formulär, verifiera formulär och mycket mer.

Nu är det snart dags för Symfony2 att lanseras. Det är många prestanda fördelar jämfört med version 1.4. Jag längtar att få testa det. Jag har ett par projekt som jag ska testa Symfony2 med i sommar.

Symfony really gives me headache sometimes. It took me an hour to figure it out this time. This was my problem:
When executing the command

php symfony doctrine:build --all

I got this error:

SQLSTATE[HY000]: General error: 1005 Can't create table

It may be that you are trying to set a relation between two tables but the references have different types. In Symfony 1.2 sfDoctrineGuardPlugin use a integer(4) (INTEGER) as primary key. In Symfony 1.4 sfDoctrineGuardPlugin use a integer(4) (BIGINT) as primary key.

It’s a good thing to know and I hope you didn’t spend that much time trying to solve this yourself. Blog about this article to help others.
