How to repeat form elements for rows from database - php

Question

I have a form which works as I expect it to (code below) and I can populate this with one row from a database via Doctrine.
However, I'm struggling to see how to repeat the elements of this form to edit all rows (e.g. 20 of them) in one form; with the hope of updating all fields of all rows in a single form on a single page.
For example:
name[0]
description[0]
url[0]
name[1]
description[1]
url[1]
name[2]
description[2]
url[2]
I've see the use of collection's suggested but they don't seem to suit repeating all of the form from what I can understand.
Form:
namespace Acme\Bundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
class ContactType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add(
'name',
'text',
array(
'label' => 'Company Name'
)
)
->add(
'description',
'text',
array(
'label' => 'Company Description'
)
)
->add(
'url',
'text',
array(
'label' => 'Company URL'
)
)
->add(
'Update Companies',
'submit'
);
}
public function getName()
{
return 'ContactType';
}
}
Entity:
<?php
namespace Acme\Bundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Contacts
*
* #ORM\Table(options={"engine":"MyISAM", "collate":"utf8_general_ci", "charset":"utf8"})
* #ORM\Entity
*/
class Contacts
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="text", nullable=true)
*/
private $name;
/**
* #var string
*
* #ORM\Column(name="description", type="text", nullable=true)
*/
private $description;
/**
* #var string
*
* #ORM\Column(name="url", type="text", nullable=true)
*/
private $url;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* #param string $name
* #return Contacts
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* #return string
*/
public function getName()
{
return $this->name;
}
/**
* Set description
*
* #param string $description
* #return Contacts
*/
public function setDescription($description)
{
$this->description = $description;
return $this;
}
/**
* Get description
*
* #return string
*/
public function getDescription()
{
return $this->description;
}
/**
* Set url
*
* #param string $url
* #return Contacts
*/
public function setUrl($url)
{
$this->url = $url;
return $this;
}
/**
* Get url
*
* #return string
*/
public function getUrl()
{
return $this->url;
}
}

I think the collections will suit your need.
Create a form class which have one field, the collection of your ContactType :
class MyFormClassType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add(
'myField',
'collection',
array(
'type' => new ContactType ()
)
);
}
public function getName()
{
return 'my_class';
}
}
With this you can add, in the same form, a collection of Contact !
