                                                      array(
                                                        new sfValidatorSchemaCompare('email', '==', ''),
                                                        new sfValidatorSchemaCompare('phone', '==', ''),
                                                      ),
                                                      array(),
                                                      array('invalid' => 'El e-mail no tiene un formato correcto',
                                                            'required'   => 'Campo obligatorio'
                                                            )
                                                    ));

it doesn't work... :(

Answer 1

I'm not sure if there is a better method but you could use sfValidatorOr to check if one of the fields validates (i.e set required to true).

More about sfValidatorOr: http://www.symfony-project.org/forms/1_2/en/B-Validators#chapter_b_sub_sfvalidatoror

Answer 2

When comparing two separate fields you should use a global validator: http://www.symfony-project.org/forms/1_2/en/02-Form-Validation#chapter_02_global_validators. Your current approach will always mark the phone field as invalid when an error occurs. Also, the conditions you supply to the validator should return true when the values are valid so in your case you should be using a ValidatorOr with != comparisons like this:

$this->validatorSchema->setPostValidator(new sfValidatorOr(
  array(
    new sfValidatorSchemaCompare('email', '!=', ''),
    new sfValidatorSchemaCompare('phone', '!=', ''),
  ),
  array(),
  array('invalid' => 'Campo obligatorio')
));

Hope that helps.
