Question

i have created a custom validator but when I want to use it, it seems that it is never executed!

the validator :

class sfTestUrlValidator extends sfValidatorUrl {

    public function initialize($context, $parameters = null) {

        // Initialize parent
        parent::initialize($context);
    }

    public function execute(&$value, &$error) {


        if($value == "http://www.librosweb.es/")
        {
            //$error = "noooooooooooooo";
            return true;
        }

        else            return false;

    }

}

in the configure method of a form, i do like that :

public function configure() { 
 .....
....
 'url' => new sfTestUrlValidator(),

You need to override sfValidatorBase::doClean method and not some not-existent execute method and throw exception intead of returning true/false. Have a look at any validator class, e.g. sfValidatorString. However in your case, I would simply use sfValidatorChoice with one choice

public function configure() 
{ 
 'url' => new sfValidatorChoice(array('choices' => array(
   'your.website.url',
 )));
}
