Symfony 2 - Delete Forms and CSRF Token

Question

I have a List of entries coming from a database. I would like to have a \"Delete-Button\" at the end of every row, so that the user won\'t have to first go to the edit/show page

Answer 1

You may render individual tokens with:

{{ form_widget(form._token) }}

or specifically for your case:

{{ form_widget(delete_form._token) }}

But, I think you are better served making an array of forms and fully rendering each one:

In your controller:

public function indexAction()
    {
        $em = $this->getDoctrine()->getManager();
        $rep= $em->getRepository('IntranetServicesBundle:Laender')
                ->createQueryBuilder('l');

        var_dump($rep->getQuery()->getDql());
        $entities=$rep->getQuery()->getResult();

        $delete_forms  = array_map(
            function($element){ 
                return $this->createDeleteForm($element->getId());}
            ,$entities->toArray()
            );

        return $this->render('IntranetServicesBundle:Laender:index.html.twig'
                           , array(
                                 'entities'        => $entities,
                                 'delete_forms'    => $delete_forms
                           ));
    }


private function createDeleteForms($id)
{
    return $this->createFormBuilder(array('id' => $id)))
        ->add('id', 'hidden')
        ->getForm()
    ;
}

public function deleteAction(Request $request, $id)
{
    $form = $this->createDeleteForm($id);
    $form->bind($request);

    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();

        $entity = $em->getRepository('IntranetServicesBundle:Laender')
                     ->find($id);
        // this line might need to be changed to point to the proper repository

        if (!$entity) {
            throw $this->createNotFoundException('Unable to find Laender entity.');
        }

        $em->remove($entity);
        $em->flush();
    }

    return $this->redirect($this->generateUrl('laender_index'));
    // this line might need to be changed to point to the proper 
    // post-delete route
}

In your twig do something along the lines of:

{% for form in delete_forms %}{{form_widget(form)}}{% endfor %}
