php - Custom Validation with Phalcon Model -

i trying implement custom validation models. using included validators phalcon library, when try implement mine, doesn't work. here code:

    <?php  use phalcon\mvc\model\validator; use phalcon\mvc\model\validatorinterface; use phalcon\mvc\entityinterface;  class maxminvalidator extends validator implements validatorinterface {      public function validate(entityinterface $model)     {         $field  = $this->getoption('field');          $min    = $this->getoption('min');         $max    = $this->getoption('max');          $value  = $model->$field;          if ($min <= $value && $value <= $max) {             $this->appendmessage(                 "the field doesn't have right range of values",                 $field,                 "maxminvalidator"             );             return false;         }         return true;     } } 

i trying use in model this:

public function validation() {         $this->validate(new maxminvalidator(             array(                 "field" => "email",                 "min"   => 10,                 "max"   => 100             )         ));  } 

the class correctly loaded, doesn't execute validation function , code stops being executed after trying validate. note: exact same code found here.

1.check validator class loaded properly. (create function , write die("sth");) if calling function causes app die loaded class properly.

2.check phalcon version if under 2.0.5 should modify validator code to:

<?php  use phalcon\mvc\model\validator; use phalcon\mvc\model\validatorinterface; use phalcon\mvc\entityinterface;  class maxminvalidator extends validator implements validatorinterface {     public function validate(\phalcon\mvc\modelinterface $model)     {          $field  = $this->getoption('field');          $min    = $this->getoption('min');          $max    = $this->getoption('max');           $value  = $model->$field;           if ($min <= $value && $value <= $max) {              $this->appendmessage(              "the field doesn't have right range of values",              $field,              "maxminvalidator"              );             return false;         }         return true;     } } 

and if phalcon version 2.0.5 , class loaded u can't see validation error message add method model class:

public function getmessages() {     $messages = array();     foreach (parent::getmessages() $message) {         switch ($message->gettype()) {             case 'invalidcreateattempt':                 $messages[] = 'the record cannot created because exists';                 break;             case 'invalidupdateattempt':                 $messages[] = 'the record cannot updated because exists';                 break;             case 'presenceof':                 $messages[] = 'the field ' . $message->getfield() . ' mandatory';                 break;             case 'maxminvalidator':                 $messages[] = 'the field ' . $message->getfield() . ' not in range';                 break;         }     }     return $messages; }
