I have a form in Symfony 4 where I implement the DateType as a text field
->add('DateOfBirth', DateType::class, array(
'required' => false,
'widget' => 'single_text',
'empty_data' =
))
however the field is optional to fill in for the form. When I submit the form with an empty value for that field I receive the error:
Expected argument of type "DateTimeInterface", "NULL" given.
erroring on the line
$form->handleRequest($request);
It seems I need to pass in a default value (i.e. - 1/1/1990) as null is not a valid DateTime value? What is the correct way to handle this? I looked on this page and tried various things (i.e. - changing input type) but nothing seems to fix this.
Thanks in advance!
