Symfony2，isValid（）和$ this-> get（'validator'）之间的区别

Question

I'm new in Symfony2 and I wish to know what's the difference of validate a form between:

$form->isValid()

and

$this->get('validator')->validate($form->getData())

using validation rules in validations.yml

Thank you!

Answer 1

The validator, in your case, checks object to which the form was bound. The Form::isValid() method, besides, checks a form status (whether the form was submitted, whether it was disabled).
