Возможно, слишком поздно, но в итоге мне это удается. Возможно, это поможет вам.
Вот мой FormType:
class PersonType extends AbstractType{
public function buildForm(FormBuilderInterface $builder, array $options){
$builder->add('mother', 'personSelector', array('personEntity' => $options['personEntity']));
}
}
Вот мой customField, где есть проверки:
class PersonSelectorType extends AbstractType{
public function buildForm(FormBuilderInterface $builder, array $options){
$transformer = new PersonByFirstnameAndLastnameTransformer($this->entityManager,$options);
$builder->addModelTransformer($transformer);
$builder->addEventListener(FormEvents::PRE_SUBMIT, array($this, 'onPreSubmitForm'));
}
public function onPreSubmitForm(FormEvent $event){
$mother = $event->getData();
$form = $event->getForm();
$options = $form->getConfig()->getOptions();
if (!empty($mother)){
preg_match('#(.*) (.*)#', $mother, $personInformations);
if (count($personInformations) != 3){
$form->addError(new FormError('[Format incorrect] Le format attendu est "Prénom Nom".'));
}else{
$person = $this->entityManager->getRepository($options['personEntity'])->findOneBy(array('firstname' => $personInformations[1],'lastname' =>$personInformations[2]));
if ($person === null) {
$form->addError(new FormError('Il n\'existe pas de person '.$personInformations[1].' '.$personInformations[2].'.'));
}
}
}
}
}
Вот мой трансформатор:
class PersonByFirstnameAndLastnameTransformer implements DataTransformerInterface{
public function reverseTransform($firstnameAndLastname) {
if (empty($firstnameAndLastname)) { return null; }
preg_match('#(.*) (.*)#', $firstnameAndLastname, $personInformations);
$person = $this->entityManager->getRepository($this->options['personEntity'])->findOneBy(array('firstname' =>$personInformations[1],'lastname' =>$personInformations[2]));
if (count($personInformations) == 3){
$person = $this->entityManager->getRepository($this->options['personEntity'])->findOneBy(array('firstname' =>$personInformations[1],'lastname' =>$personInformations[2]));
}
return $person;
}
public function transform($person) {
if ($person === null) { return ''; }
return $person->getFirstname().' '.$person->getLastname();
}
}
