By default, the translation domain for the Symfony 2 validator is ‘validators’ and the translations are stored in the resources/translations/validators.<locale>.xliff files. In some applications it might be nice to use the same translation file as the rest of the site translations for validation messages, rather than using a separate validation translation file. Symfony makes this easy by setting a single parameter.
Lets say we want our translated validation messages for the AcmeStoreBundle’s to be stored in the messages.<locale>.xliff files instead of the validators.<locale> files. To do this we simply need to set the validators translation domain.
Add the following to your parameters.yml file:
# app/config/parameters.yml
parameters:
validator.translation_domain: messages
After we add the translation domain parameter the validator will check the src/Acme/StoreBundle/Resources/translations/messages.<locale>.xliff file for a translation instead of the src/Acme/StoreBundle/Resources/translations/validators.<locale>.xliff file.
I need to to thank you for this very good read!! I absolutely enjoyed every little bit
of it. I have got you book marked to look at new
stuff you post…
Woah! I’m really digging the template/theme of this site.
It’s simple, yet effective. A lot of times it’s tough to get that
“perfect balance” between superb usability and visual appeal.
I must say you’ve done a fantastic job with this. Additionally, the blog loads very quick for me on Chrome.
Outstanding Blog!
Actually there is no need to override a symfony parameter.
Just configure following in config.yml:
framework:
validation:
translation_domain: messages
Please note that if you use the JMSSerializerBundle you will have to override the parameter ‘jms_serializer.form_error_handler.class’ with a custom class of yours, because the default class forces the translation domain to ‘validators’ for error messages.
