symfony 2.3 form getData doesn't work in subforms collections

Question

I have a form which contains a collection. So I have:

/* my type */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
             


        

Answer 1

In a submit or if you are editing, you can access the data when you turn the FormBuilder into a Form instance. And for a collection type you can try this:

...
$form = $formBuilder->getForm();
...
if ($this->getRestMethod() == 'POST') {
    $form->handleRequest($this->get('request'));
    if ($form->isValid()) {
        $formData = $form->getData();
        foreach ($formData['photos'] as $key => $collectionRow) {
            var_dump($collectionRow['photoname']);
            var_dump($collectionRow['size']);
        }
    }
}
