Optional embed form in Symfony 2

Question

I have two entities in my system: Person and Phone as the following code.

class Person
{
    /**
     * @ORM\\Id
     * @ORM\\Colum         


        

Answer 1

I would try this method:

create additional method in your Phone entity which validates if all fields are null or all fields are not null (these two cases are correct) - and then return true. If some fields are null and some aren't return false. Add an assert annotation to your new method - this will be your new constraint.

/**
 * @Assert\True(message = "Fill all fields or leave all them blank")
 */

And this should work.

For more information look here: http://symfony.com/doc/master/book/validation.html#getters

edit:

Try this one:

define your custom validation method (this one which check if any of phone fields is filled) as Callback (at the top of the class):

 * @Assert\Callback(methods={"checkPhoneFields"})
 */
 class Phone {

Next you mark field wich have to be validated with validation group, eg.

/**
 * @ORM\Column(type="string", length=16, groups={"phone_validation"})
 */
private $number;

And the last thing, in your custom constraint method you need to switch on "phone_validation" group if any of field isn't empty:

public function checkPhoneFields(ExecutionContext $context) {
    if (/* fields are not empty */) {
        $context->getGraphWalker()->walkReference($this, 'phone_validation', $context->getPropertyPath(), true);
    }

And that should work.
