I'm working in a bundle where the user creates a "comision" using a form, and I'm trying to check that the user still have "credit". So I created a custom validator that queries past comisions and throws an error if credit is not enough.
My problem is that if the user submits a date with a wrong format in the "date" field (i.e. 32-13-20122 24:05) Symfony still tries to run my custom validation and I get all sort of errors (because $comision->getDate() is null and not a valid DateTime object).
I'm getting this error:
clone method called on non-object
I can also check if value of $comision->getDate() is a valid datetime in my custom validator, but it seems to me that it should be not necessary since I added this rules in the date property.
This is my entity (simplified)
/**
* @MyValidation\TotalHours()
*/
class Comision
{
/**
* @ORM\Column(type="datetime")
* @Assert\DateTime()
* @Assert\NotNull()
*/
protected $date;
/**
* @ORM\Column(type="decimal", nullable=false, scale=1)
* @Assert\NotBlank()
*/
protected $hours;
...
My form class ...
class NewComisionType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('date', DateTimeType::class, array(
'widget' => 'single_text',
'label' => 'Starting date and time',
'format' => 'dd/MM/yyyy HH:mm'
))
->add('hours', ChoiceType::class, array(
'label'=> 'How many hours',
'choices' => array(
'1:00' => 1,
'1:30' => 1.5,
'2:00' => 2,
'2:30' => 2.5,
'3:00' => 3
)
))
...
And my cutom validator that checks past comisions to find if user still has "credit"
public function validate($comision, Constraint $constraint)
{
$from = clone $comision->getDate();
$from->modify('first day of this month');
$to = clone $comision->getDate();
$to->modify('last day of this month');
$credit = $this->em->getRepository("ComisionsBundle:Comision")->comisionsByDate($comision,$from, $to);
...
