maximum length form validation

Question

Just going through symblog.co.uk symfony2 tutorial. i'm kind of stuck in validations. At first it kept giving erros but i found this article in which author corrects mistakes which source is tutorial being old. anyway, article tells me to change validator in

src/Blogger/BlogBundle/Entity/Enquiry.php:

from

$metadata->addPropertyConstraint('body', new MaxLength(50));

to:

$metadata->addPropertyConstraint('body', new Length(array('min'=> 50)));

It works, yay! Same way i changed

 $metadata->addPropertyConstraint('subject', new MaxLength(50));

into

$metadata->addPropertyConstraint('subject', new Length(array('max'=>50)));

But this time there is no validation performed. Where is the mistake? How should maximum-length validation looks like?

Answer 1

According to the docs

use Symfony\Component\Validator\Constraints as Assert; 

…

$metadata->addPropertyConstraint('firstName', new Assert\Length(array(
    'min'        => 2,
    'max'        => 10
)));
