How to extract labels from Symfony forms I18n Extract Task

I am quite aware that the extract task accepts application as a parameter, and th开发者_运维知识库us one can't expect it too look into the forms folder. However, I referred the link (below) and tried a couple of ways: 1. defining my proxy __() method 2. including the I18n helper in App Configuration However, both aren't working.

Can anyone tell me how to extract these from the form classes? Thanks

You need to use the i18n helper and add the translated strings manually to your XML/XLIFF files. The translations themselves work, it's just the i18n:extract task that doesn't look inside form classes so it has to be done manually. I hope they add this feature in Symfony 2.0.

See the first few paragraphs here: http://www.symfony-project.org/forms/1_4/en/08-Internationalisation-and-Localisation

There's a way to extract it altough it's not recommended by the developers:

In lib/i18n/extract/sfI18nApplicationExtract.class.php add:

$this->extractFromPhpFiles(sfConfig::get('sf_lib_dir').'/form');     

to function extract()

In your form class's configure method add: sfLoader::loadHelpers('I18N');

This way you can use the __() function in your form class.

I'm currently testing it. Will share my findings.
