https://gist.github.com/webdevilopers/9cfeab0bd5c20af6d0b6adfa63d2cdcf How to pass options from resolver to Symfony Form Event

I need to get the translation_domain from the options inside an Symfony Form Event.

Since the actual event callback function for onPreSubmit can grow very big I would like to use the addEventListener method linking to the separate method instead of using the function:

http://symfony.com/doc/current/form/dynamic_form_modification.html#adding-an-event-listener-to-a-form-class Unfortunately without the function I cannot pass the $options? viause`.

The solution I came up with is to get the options from the Form Config:

$form->getConfig()->getOption('translation_domain')

CustomerInformation .php
content_copyfile_download
<?php

class CustomerInformation extends AbstractType
{
    /**
     * @var Translator $translator
     */
    private $translator;

    public function __construct(
        Translator $translator
    ) {
        $this->translator = $translator;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->addEventListener(
            FormEvents::PRE_SUBMIT,
            [$this, 'onPreSubmit']
        );
    }

    public function onPreSubmit(FormEvent $event)
    {
        $data = $event->getData();
        $form = $event->getForm();

        if (!empty($data['customerId'])) {
            // ...
            if (count($customer->customerPriceLists()) === 0) {
                $form->addError(new FormError($this->translator->trans(
                    'No price list linked from QSP to customer.',
                    [],
                    $form->getConfig()->getOption('translation_domain')
                )));
            }
        }
    }
      
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'translation_domain' => 'order_entry'
        ]);
    }
}
