Update entities fields with data from other entity symfony2 - php

Question

I have two tables in database - orders and trucks. They have relation ManyToOne. When I receive order - truck field is null by default. Trucks table have preconfig data. So my task: for every order entity which I restore with findAll() method and send to twig (render as table) make checkbox, so I can appoint truck to every order.
Here is form which appoint truck to order:
class TruckType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('name', 'entity', array(
'class' => 'AppBundle:Trucks',
'choice_label' => 'name',
'label' => false,
'multiple' => false,
'required' => false,
));
}
/**
* #param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Orders',
));
}
/**
* Returns the name of this type.
*
* #return string The name of this type
*/
public function getName()
{
return 'TruckType';
}
}
And twig:
{% for order in orders %}
<tr>
<td width="30%">{{ order.name }}</td>
<td width="30%">{{ order.delivery }}</td>
<td width="15%">{{ order.stock }}</td>
<td width="15%">{{ form_widget(truckform) }}</td>
</tr>
{% endfor %}
But this render checkbox only for first entity in table. Where I am wrong?

Answer 1

You did not show the code for how you generate your truckform variable but I guess you just instantiate a form using your TruckType form type. The problem with this approach is that Symfony will not render a form or a form field more than once, so that your {{ form_widget(truckform) }} fragment is only rendered the first loop iteration. If you think about it, it makes sense, otherwise you will have a number of form fields all with the same name and id and when you submitted your form, there will be no way to differentiate them. You need to take a different approach, using embedded forms. Take a look at this Symfony doc page which will point you in the right direction: How to Embed a Collection of Forms
