What the real requirement is that condition1 or condition2, one of then satisifed, then pass.

But I found the validator chain is the relationship and not or

class CommentMainForm extends Form implements InputFilterProviderInterface
{
    public function init() : void
    {
        $this->add([
            'name' => 'id',
            'type' => Hidden::class,
        ]);

        $this->add([
            'name' => 'threadid',
            'type' => Hidden::class,
        ]);

        $this->add([
            'name' => 'parentid',
            'type' => Hidden::class,
        ]);

        $this->add([
            'name' => 'content',
            'type' => Hidden::class,
        ]);

        $this->add([
            'name' => 'time',
            'type' => Hidden::class,
        ]);

        $this->add([
            'name' => 'formhash',
            'type' => Hidden::class,
        ]);
    }

            ],
        ];
    }
}

as you can see parentid, it can be 0 or a table id(primary key), both ok for me.
I use a exclude option to resolve this problem here.

But let’s think it futher, If not a RecordExists::class validator. I want just to satisfied one of the contion it will pass. how?

I would write a custom validator - called ZeroOrRecordExists or something - to handle the OR logic…

final class ZeroOrRecordExists extends AbstractValidator
{
    private RecordExists $recordExistsValidator;

    public function __construct($options = null)
    {
        $this->recordExistsValidator = new RecordExists($options);
    }

    public function isValid($value) 
    {
        return ($value === 0 || $this->recordExistsValidator->isValid($value);
    }

    public function getMessages()
    {
        return $this->recordExistsValidator->getMessages();
    }
}

Just an idea, and there are probably more methods you’ll need to proxy (err… setOptions() is one), but that’s the idea. (I’ve got a ton of NullOr... ones for a similar purpose).

Ok, thank you! That seems good.
