i have a little problem with form. I have made form class and i need form field which will be like radio or select. Choices for select i need to pull from DB of another form. Here is the code so pls tell me where is my problem and how to solve it.
I want to have option when i create POST to choose from available pages (their names) and store that so i know for each post to which page it belongs and for each page i do query and show posts for that page..
<?php
namespace AppBundle\AppForm;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use AppBundle\Entity\Page;
class PostForm extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name', 'text')
->add('content', 'textarea')
->add('visible', 'choice', array(
'choices' => array(
'Yes' => 1,
'No' => 0
)
))
->add('belongToPage', 'choice', array(
'choices' => array (
new Page()
// here i want to pull from class Page names of
//all pages stored and to present
// this names for options in form field
),
'choices_as_values' => true,
'choice_label' => 'getName'
//getName is function from class Page which returns name of page(s)
))
->add('save', 'submit', array('label' => 'Create Post'));
}
public function getName()
{
// TODO: Implement getName() method.
}
}

Why don't you use entity
field type. It would be smth like this:
->add('belongToPage', 'entity', array(
'class' => 'Class\Namespace\Class',
'property' => 'name',
'label' => 'choice_field_label'
))
If you need smth more complicated then just findAll
for this field, you could use query_builder
option:
->add('belongToPage', 'entity', array(
'class' => 'Class\Namespace\Class',
'property' => 'name',
'label' => 'choice_field_label',
'query_builder' => function(EntityRepository $er) {
return $er->findAllPagesForPostForm();
//Where findAllPagesForPostForm is the name of method in your
// pagesRepo which returns queryBuilder,
//instead of this you could just write your custom query like
//$qb = $er->createQueryBuilder('p');
//$qb->andWhere(...);
//return $qb;
}
))
