symfony2 edit more entities in same page - php

Question

How can edit more products entities in same page (no 1 to many).
In My editaction :
$entities=$em->getRepository('MyBundle:Product')->findAll();
$editForm=array();
$deleteForm=array();
foreach ($entities as $product )
{
$editForm [$port->getId()]= $this->createEditForm($product);
$deleteForm[$port->getId()] = $this->createDeleteForm($product->getId());
}
return $this->render('MyBundle:Product:edit.html.twig', array(
'entities' => $entities,
'edit_form' => $editForm->createView(),
'delete_form' => $deleteForm->createView(),
));
I have this error :
Error: Call to a member function createView() on a non-object
And how update the edit.thml.twig to show all form update as table with only one submit ?

Answer 1

This is not about Symfony2, but about PHP, you are calling a method onto an array...
Consider something like this :
$entities = $em->getRepository('MyBundle:Product')->findAll();
$editForms = array();
$deleteForms = array();
foreach ($entities as $product)
{
$editForms[$port->getId()] = $this->createEditForm($product)
->createView();
$deleteForms[$port->getId()] = $this->createDeleteForm($product->getId())
->createView();
}
return $this->render('MyBundle:Product:edit.html.twig', array(
'entities' => $entities,
'edit_forms' => $editForms,
'delete_forms' => $deleteForms,
));
With a template like this one :
{% for form in edit_foms %}
{{ form(form) }}
{% endfor %}
{% for form in delete_foms %}
{{ form(form) }}
{% endfor %}

I have fix this :
change the name of form:
public $name;
/**
* #return string
*/
public function getName()
{
return (string)'port_'.$this->name;
}
public function __construct($name=0) {
$this->name=$name;
}
and in my controller
editAction :
$entities = $em->getRepository('InfraProductBundle:InfraPortDdf')->findAll();
foreach ($entities as $port )
{
$editForm [$port->getId()]= $this->createEditForm($port);
$edit_view[$port->getId()]=$editForm[$port->getId()]->createView();
}
return $this->render('......:edit.html.twig', array(
'entities' => $entities,
'edit_form' => $edit_view,
));
in update action
foreach ($array_id as $key=>$id){
if(!is_numeric(str_replace('port_','',$id)))
continue;
$entity = $em->getRepository('InfraProductBundle:InfraPortDdf')->find(str_replace('port_','',$id));
if (!$entity) {
throw $this->createNotFoundException('Unable to find InfraPortDdf entity.');
}
$editForm = $this->createEditForm($entity);
if($editForm->submit($request->request->get($id)))
$em->flush();
}
in my edit.html.twig:
{% for key, edit in edit_form %}
...
{{form_widget(edit.description,{name:'['~key~'][description]', 'attr': { 'name' : '['~key~'][description]' } } ) }}
....
{%endfor%}
