symfony1 - symfony 1.1 sfNumberValidator plugin code in php -

i have validation check in validate/confirm.yml on field postalcode as:

 postalcode:     required: yes   required_msg: enter_valid_postalcode   validators: numbervalidator   numbervalidator:   class: sfnumbervalidator   nan_error:    not_a_number_error 

for reason want move logic or same functionality of class sfnumbervalidator in action file.

like

class registeractions extends sfactions {     public function validateconfirm() {             ....             ...         $postalcode = $this - > getrequestparameter('postalcode');          if (postalcode != '') {              //do same kind of validation sfnumbervalidator           }      } .... } 

you have create sfnumbervalidator instance , call execute method.

something this:

if ($postalcode != '') {    $validator = new sfnumbervalidator($this->getcontext(), array(            'nan_error' => 'not number',            'min'       => 10000,            'max'       => 99999   ));   $error = null;    if(!$validator->execute($potalcode, $error)){       //here $error has message want show user   }   } 

ps: min , max suggestion should maybe use more explicit postal code case
