A piece of code that will extract the existing labels from a form into a xliff file. It will only pick out the labels that have been set by the widgetForm->setLabel() command.

example for UserForm.class.php you can extract it using:

   php symfony i18n:extract-form user
 

.

<?php
 
class i18nExtractFormTask extends sfBaseTask
{
  protected function configure()
  {
    // // add your own arguments here
    // $this->addArguments(array(
    //   new sfCommandArgument('my_arg', sfCommandArgument::REQUIRED, 'My argument'),
    // ));
 
    $this->addOptions(array(
      new sfCommandOption('application', null, sfCommandOption::PARAMETER_REQUIRED, 'The application name', 'frontend'),
      new sfCommandOption('env', null, sfCommandOption::PARAMETER_REQUIRED, 'The environment', 'dev'),
      new sfCommandOption('connection', null, sfCommandOption::PARAMETER_REQUIRED, 'The connection name', 'default'),
      new sfCommandOption('source', null, sfCommandOption::PARAMETER_REQUIRED, 'Source language', 'en'),
      // add your own options here
    ));
 
    $this->addArgument('form', sfCommandOption::PARAMETER_REQUIRED, 'Name for the form to translate');
 
 
    $this->namespace        = 'i18n';
    $this->name             = 'extract-form';
    $this->briefDescription = 'Extracts the labels from a form';
    $this->detailedDescription = <<<EOF
The [i18n-extract-form|INFO] task extracts the labels from a form class into a XLIFF file.

   for CoolForm.class.php you can extract it using:
