Methods getDefaultOptions and getAllowedOptionValues of FormTypeInterface and FormTypeExtensionInterface are deprecated and will be removed in Symfony 2.3.

• The following methods of FormTypeInterface and FormTypeExtensionInterface are deprecated and will be removed in Symfony 2.3:

  • getDefaultOptions
  • getAllowedOptionValues

  You should use the newly added setDefaultOptions instead, which gives you access to the OptionsResolverInterface instance and with that a lot more power.

  Before:

  public function getDefaultOptions(array $options)
  {
    return array(
        'gender' => 'male',
    );
  }
  
  public function getAllowedOptionValues(array $options)
  {
    return array(
        'gender' => array('male', 'female'),
    );
  }

  After:

  public function setDefaultOptions(OptionsResolverInterface $resolver)
  {
    $resolver->setDefaults(array(
        'gender' => 'male',
    ));
  
    $resolver->setAllowedValues(array(
        'gender' => array('male', 'female'),
    ));
  }

  You can specify options that depend on other options using closures.

  Before:

  public function getDefaultOptions(array $options)
  {
    $defaultOptions = array();
  
    if ($options['multiple']) {
        $defaultOptions['empty_data'] = array();
    }
  
    return $defaultOptions;
  }

  After:

  public function setDefaultOptions(OptionsResolverInterface $resolver)
  {
    $resolver->setDefaults(array(
        'empty_data' => function (Options $options, $value) {
            return $options['multiple'] ? array() : $value;
        }
    ));
  }

  The second argument $value contains the current default value and does not have to be specified if not needed.
