Symfony2 forms interpret blank strings as nulls

Question

I have a Symfony2 form with a variety of fields, including one optional text field called recap.

This recap field saves perfectly when there\'s

Answer 1

I have another solution for this issue:

create dummy class

class EmptyString {
    public function __toString() {
        return '';
    }
}

and set

$builder->add('recap', 'text', [
    'empty_data' => new EmptyString(),
]);

When entity will be stored to DB, it will automatically converted to empty string.
