I'm building an application in Symfony2. I want to get the translations of validation messages. I read about Silex, but not have idea how to integrate with Symfony2, if i need to install something, or where i need to configure my project. I already have validators.*.xliff file on Resources/translations, but still get validation messages in English. Any idea?
Well first make sure you've correctly set up the default locale for your application (file app/config/config.yml).
Then I strongly advice you to read the official documentation for a step by step on how translation works in Symfony2.
