Is it possible to validate a property of a model class dependent on another property of the same class?
For example, I have this class:
class Conference
{
/** $startDate datetime */
protected $startDate;
/** $endDate datetime */
protected $endDate;
}
and I want that Symfony 2.0 validates, that $startDate has to be after $endDate.
Is this possible by annotations or do I have to do this manually?
Yes with the callback validator: http://symfony.com/doc/current/reference/constraints/Callback.html
On symfony 2.0:
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\ExecutionContext;
/**
* @Assert\Callback(methods={"isDateValid"})
*/
class Conference
{
// Properties, getter, setter ...
public function isDateValid(ExecutionContext $context)
{
if ($this->startDate->getTimestamp() > $this->endDate->getTimestamp()) {
$propertyPath = $context->getPropertyPath() . '.startDate';
$context->setPropertyPath($propertyPath);
$context->addViolation('The starting date must be anterior than the ending date !', array(), null);
}
}
}
On symfony master version:
public function isDateValid(ExecutionContext $context)
{
if ($this->startDate->getTimestamp() > $this->endDate->getTimestamp()) {
$context->addViolationAtSubPath('startDate', 'The starting date must be anterior than the ending date !', array(), null);
}
}
Here I choose to show the error message on the startDate field.
