In this project I'm building, I have many forms to add data to the database that the site uses. Obviously, if a user add's data they must be able to edit this data (or delete it).
I've looked through the book and it talks at length about using a form to add data. However, it doesn't seem to mention how forms can be used to edit data.
How can this be achieved?
Cheers
If you want, it's quite easy to write your edit action without doctrine, you should do something like this:
public function editAction( $id ) {
$em = $this->getDoctrine()->getEntityManager();
$repository = $em->getRepository('YourBundle:YourEntity');
$element = $repository->find( $id );
if ( false !== is_null( $element ) ) {
throw $this->createNotFoundException( 'Couldn\'t find element ' . $id . '!');
}
$form = $this->createForm( new YourFormType(), $element );
$request = $this->getRequest();
if ( $request->getMethod() == 'POST' ) {
$form->bindRequest( $request );
if ( $form->isValid() ) {
$em->persist( $element );
$em->flush();
$this->get( 'session' )->setFlash( 'system-message', 'Element Updated!' );
return $this->redirect( $this->generateUrl( 'Your_route' ) );
}
}
return $this->render('YourBundle:YourView:your_template.html.twig', array( 'element' => $element, 'form' => $form->createView() ) );}
The only different thing of the edit action with the new action is that, instead of creating a new "element" instance, you get it from the entity manager, you could even set any arbitrary values to your element before attaching it to the form.
I hope it helps!
Use the generate:doctrine:crud task to generate code for editing/updating users. You'll see that the newAction and the editAction are very similar.
