Symfony2: Upgrading 2.0 to 2.1 – CallbackValidator

Posted November 12th, 2012 in Razno by Metod

The CallbackValidator class was deprecated in 2.1.

If you implemented custom validators using this interface, you can substitute them by event listeners listening to the FormEvents::POST_BIND (or any other of the *BIND events). In case you used the CallbackValidator class, you should now pass the callback directly to addEventListener.

Here is how you do it.



Enjoy! 😉
