Zend Form：将图片移动到文件夹中

Question

I'm working on a project with ZF2 and Zend Form. I'd like to add an avatar into a user profile.

The problem is that I only get the file name and save it in the DB. I would like to insert it into a folder so I'll be able to get it and display it. The rest of the form is working.

My guess is that I have to get information from $FILES, but I have no idea how to do this. I've read the documentation but can't see how to apply this to my project.

Thank you in advance!

Here's my Controller Action

public function signinAction()
    {
        $this->em = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default');

        $form = new SignupForm($this->em);

        $model = new ViewModel(array("form" => $form));

        $url = $this->url()->fromRoute("signin");
        $prg = $this->prg($url, true);

        if($prg instanceof \Zend\Http\PhpEnvironment\Response){
           return $prg;
        }
        else if($prg === false){
           return $model;
        }

        $user = new User();
        $form->bind($user) ;
        $form->setData($prg) ;

        if($form->isValid()){
            $bcrypt = new Bcrypt() ;
            $pwd = $bcrypt->create($user->getPassword());
            $user->setPassword($pwd);
            $this->em->persist($user) ;
            $this->em->flush() ;

            return $this->redirect()->toRoute('login');
        }

        return $model ;
    }

Here's my form file :

class SignupForm extends Form 
{
    private $em = null;

    public function __construct($em = null) {
        $this->em = $em;
        parent::__construct('frm-signup');

        $this->setAttribute('method', 'post');
        $this->setHydrator(new DoctrineEntity($this->em, 'Application\Entity\User'));

        //Other fields
         ...

        //File
        $this->add(array(
            'type' => "File",
            'name' => 'avatar',
            'attributes' => array(
                'value' => 'Avatar',
            ),     
        ));    

        //Submit
         ...         
    }   
}

And the form in my view :

        $form = $this->form;         
         echo $this->form()->openTag($form);
         //other formRow
         echo $this->formFile($form->get('avatar')); 
         echo $this->formSubmit($form->get('submit'));
         echo $this->form()->closeTag();

There are two things you could look at for getting your avatar to work:

1. Using the Gravatar view helper (uses gravatar.com service that automatically links images to email addresses)
   • documentation on using the gravatar service can be found here
2. Upload images yourself with the file upload classes that are shipped with ZF2:
   • form class for file upload can be found here
   • input filter class documentation can be found here

If you follow those docs you should be able to manage what you want.

Note: check especially the use of the Zend\Filter\File\RenameUpload filter in the example in the input filter documentation. This filter renames/moves the uploaded avatar file to the desired location.
