Uploading a file in Symfony2.3

Question

I've been having a problem trying to upload a single file with Symfony2.3. When I try to upload the file I get the following error:

FatalErrorException: Error: Call to a member function move() on a non-object in 

I have checked $csvFileForm['csvFile']->getData(); and its a string (the name of the file), also $file = $this->getRequest()->files; has size zero.

Here is the show action:

/**
 * Finds and displays a Project entity.
 *
 * @Route("/{id}", name="console_project_show")
 * @Method("GET")
 * @Template()
 */
public function showAction($id)
{
    $csvFileForm = $this->createFormBuilder()
        ->add('csvFile', 'file')
        ->getForm();

    return array(
        'csvFileForm' => $csvFileForm->createView()
    );
}

and the form in the template looks like this:

<form method="POST" action="{{ path('console_project_upload_urls', { 'id': entity.id }) }}" >
  {{ form_row(csvFileForm.csvFile) }}
  {{ form_row(csvFileForm._token) }}
  <input type="submit" name="submit" class="submit"/>
</form>

The upload action is this:

/**
 * Lists all Project entities.
 *
 * @Route("/{id}/upload-urls", name="console_project_upload_urls")
 * @Method("POST")
 */
public function uploadUrlsAction(Request $request, $id)
{
    $csvFileForm = $this->createFormBuilder()
        ->add('csvFile', 'file')
        ->getForm();

    $request = $this->getRequest();

    $csvFileForm->handleRequest($request);

    $data = $csvFileForm['csvFile']->getData();
    $data->move(".", "something.csv"); // This is where the exception occurs

    $file = $this->getRequest()->files; // I have used this to check the size of the array

    return $this->redirect(...);
}

Thanks for any help.

You have to add the enctype to your form tag.

<form method="POST" action="{{ path('console_project_upload_urls', { 'id': entity.id }) }}" {{ form_enctype(form) }}>
    ...
</form>

Note: This is deprecated as of Symfony2.3 and will be removed in Symfony3. You should use the new form_start() twig helper.

{{ form_start(form, {'method': 'POST', 'action': path('console_project_upload_urls', { 'id': entity.id })}) }}
     ...
{{ form_end(form) }}
