How to build query if I want to get entity where has propery with propType.$id=9 and propOption=13

I try this

$builder = $this->createQueryBuilder()->select();
foreach ($propertiesArr as $propTypeId => $propOptId) {
    if (intval($propTypeId) > 0 && intval($propOptId) > 0) {
        $builder->addOr(
            $builder->expr()
                ->field('properties.propType.$id')->equals($propTypeId)
                ->field('properties.propOption.$id')->equals($propOptId)
            );
        }
    }
}

but it doesn't work

Answer 1

This code snippet doesn't work because $propOptId variable is not integer. If wrap $propTypeId and $propOptId in intval then this code will work fine.
