Multiple form lines for the same object in symfony2

Question

I am creating a simple form with several lines:

Controller:

public function indexAction() { $repository = $this->getDoctrine()->getRepository('MyBundle:Product'); $products = $repository->findAll(); foreach ($products as $product) { $forms[] = $this->createForm(new ProductType, $product)->createView(); } return $this->render('MBundle:Default:index.html.twig', array('form' => $forms); } 

I am doing this in a branch:

 <form action="{{ path('_submit') }}" method="post"> {% for key, formData in forms %} {{ form_row(formData.id) }} {{ form_row(formData.name) }} {{ form_row(formData.nameEnglish) }} <br clear="all" /> {% endfor %} </form> 

When I submit the form, each of my input fields has the same name attributes, and I only get the last one. How to capture all lines and check them in my submitAction () controller? Each input must have a unique name, right? ... and maybe I need to somehow set name = "something [name] []", but how to do it?

Ok Cerad was right with his comment, and we must use the collection for this. At first this may seem silly, but it’s right. It took me a while to get around it.

So I had to create a ProductType, which is an arrayCollection and inserts each Product. (same as in documentation with Task and tags)

I used this:

 $repository = $this->getDoctrine()->getRepository('ExampleBundle:Product'); $products = $repository->findAll(); $productCollection = new Products; foreach ($products as $product) { $productCollection->getProducts()->add($product); } $collection = $this->createForm(new ProductsType, $productCollection); return $this->render('ExampleBundle:Default:index.html.twig', array( 'collection' => $collection->createView() )); 

Then in twig I do:

 <div class="products"> {% for product in collection.products %} {{ form_row(product.id) }} {{ form_row(product.name) }} {{ form_row(product.description) }} <br clear="all" /> {% endfor %} </div> 

The task is completed.

And even you can apply themes to each line as follows:

 {% block _productsType_products_entry_name_row %} <div class="yourDivName">{{ block('form_widget') }}</div> {% endblock %} {% block _productsType_products_entry_description_row %} <div class="yourDivDescription">{{ block('form_widget') }}</div> {% endblock %} 

Cool stuff!
