Question

I have a minimum age custom validator which is straight forward enough:

The constraint(Minage.php)

namespace MyCompany\VisitBundle\Component\Validator\Constraints;
use Symfony\Component\Validator\Constraint;

/**
 * @Annotation
 */
class Minage extends Constraint
{
    public $message = 'The user must be {{ age }} or over';
    public $age = 18;

    public function validatedBy()
    {
        return get_class($this).'Validator';
    }
}

The validator (MinageValidator.php)

namespace MyCompany\VisitBundle\Component\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;

class MinageValidator extends ConstraintValidator
{
    public function isValid($value, Constraint $constraint)
    {
        $minAge = strtotime(sprintf("-%s YEAR", $constraint->age));
        if(strtotime($value->format("Y-m-d")) > $minAge)
        {
            $this->setMessage($constraint->message,
                              array('{{ age }}' => $constraint->age));
            return false;
        }
        return true;
    }
}

In my entity (stripping parts which aren’t important)

use MyCompany\VisitBundle\Component\Validator\Constraints as MyCompanyAssert;

/**
 * @ORM\Column(name="birth_date", type="datetime")
 * @MyCompanyAssert\Minage(age="18")
 */
private $birth_date;

And in twig:

{{ form_errors(form.birth_date) }}
{{ form_widget(form.birth_date) }}

I know for sure the validator is returning false but my form refuses to show the error message All other validators (out-of-the-box not custom) work fine and show their respective errors. Any idea?

Translations are disabled, so it won’t be looking for a translation in a file.

Thanks in advance.

UPDATE: form_errors(form.birth_date) does not work but form_errors(form) does? why is it assigned as a global form error?

Answer 1

The reason of this behavior is error bubbling. Set the field’s error_bubbling option to false.
