Multiple entity in one form Symfony - php

Question

I have an entity "ticket" and I would like to create a form with many of this entity.
So I created a FormType like this :
class TicketType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('quantity');
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => null,
));
}
public function getName()
{
return 'event';
}
}
And here my controller :
$clientTickets = array();
for ($i = 0; $i < 5; $i++) {
clientTickets[] = new Ticket();
}
$formTickets = $this->createForm(new TicketType(), array('tickets' => $clientTickets));
if ($request->getMethod() == 'POST') {
$formTickets->handleRequest($request);
for ($i=0; $i < $formTickets.size(); $i++) {
$em->persist($ticket[$i]);
}
}
And finally my twig :
{{ form_start(form, {'attr': {'class': 'form-horizontal', 'id': 'msform', 'name': 'myform', 'method': 'POST' }}) }}
{% for clientTicket in form.tickets %}
{{ form_widget(form.quantity) }}
{% endfor %}
{{ form_rest(form) }}
{{ form_end(form) }}
When I go on the page, I get this error :
Method "tickets" for object "Symfony\Component\Form\FormView" does not
exist in YourBundle:folder:view.html.twi at line
Why did I do wrong ? Have you got a solution ?

Answer 1

You may have to do something like this:
Let's have this form type:
class TicketType extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder - > add('field1', 'text');
$builder - > add('field2', 'text');
$builder - > add('field3', 'text');
}
public function setDefaultOptions(OptionsResolverInterface $resolver) {
$resolver - > setDefaults(array(
'data_class' = > null,
));
}
public function getName() {
return 'event';
}
}
Then in your controller you will need to have something like this:
public function testAction( )
{
$clientTickets = array(
'tickets' => array(
array(
'field1' => 'aaa',
'field2' => 'aaa',
'field3' => 'aaa'
),
array(
'field1' => 'bbb',
'field2' => 'bbb',
'field3' => 'bbb'
),
array(
'field1' => 'ccc',
'field2' => 'ccc',
'field3' => 'ccc'
)
)
);
$formTickets = $this->createFormBuilder( $clientTickets )
->add( 'tickets', 'collection', array( 'type' => new TicketType() ) )
->getForm();
if ($formTickets->handleRequest( $this->getRequest() )->isValid()) {
$data = $formTickets->getData();
var_dump( $data );
}
return array(
'form' => $formTickets->createView()
);
}
And your twig will look something like this:
{{ form_start(form) }}
<ul>
{% for clientTicket in form.tickets %}
<li>{{ form_row(clientTicket.field1) }} {{ form_row(clientTicket.field2) }} {{ form_row(clientTicket.field3) }}</li>
{% endfor %}
</ul>
{{ form_rest(form) }}
{{ form_end(form) }}
I think this code is self explanatory. Hope it helps

UPDATE:
I think you need to do something like this:
{% for i in 0..form|length %}
{{ form[i].method }}
{% endfor %}
