Get Symfony form data with unmapped fields

Question

I have a Symfony form, some fields are from entity, some not (unmapped).

I need to get full form data with those unmapped fields. I know there is a way to get those one-by-one (eg $form['unmapped']) but is there more intelligent way?

• viewData is not it - does not contain unmapped fields
• extraData - comment in code: "The submitted values that don't belong to any children."

• craigh: Some would argue the "more intelligent way" would be to utilize DTO's. Though this is old, it is still helpful: symfonycasts.com/screencast/symfony-forms/form-dto
• JohnSmith: It would but seems a bit overengineering for this problem.

Answer 1

I don't think there is a simple method in form object.

You can get them like this:

$extraFields = array_diff_key(
 $form->all(), 
 get_object_vars($form->getData()) // or just $form->getData()
);
$unmappedData = array_map(fn ($field) => $field->getData(), $extraFields);

• JohnSmith: This is simpler, no? $data = array_map(fn ($v) => $v->getData(), $form->all());. Or why array_diff_key is needed? I need full form data - both mapped and unmapped.

Answer 2

Seems there is no method for this.

I needed to iterate over all form fields and get their data:

$data = array_map(fn ($v) => $v->getData(), $form->all());

If you have nested forms, then something along those lines (untested):

$data = array_map(function ($field) {
 if ($field->getConfig()->getCompound()) {
 $fieldsData = ... // call recursively
 return $fieldsData;
 }
 return $field->getData();
}, $form->all());
