Phalcon的Validation有二個層級的，Form, Model ，下面列出各個層面的validation的class
Form:

| ExclusionIn | Validates that a value is not within a list of possible values | |
| InclusionIn | Validates that a value is within a list of possible values | |
| Regex | Validates that the value of a field matches a regular expression | |
| StringLength | Validates the length of a string | |
| Between | Validates that a value is between two values | |
| Confirmation | Validates that a value is the same as another present in the data | |
| Url | Validates that field contains a valid URL |
Model:
| Name | Explanation | Example |

自定義form層級的validator:
<?php
use Phalcon\Validation\Validator,
Phalcon\Validation\ValidatorInterface,
Phalcon\Validation\Message;
class IpValidator extends Validator implements ValidatorInterface
{
/**
* Executes the validation
*
* @param Phalcon\Validation $validator
* @param string $attribute
* @return boolean
*/
public function validate($validator, $attribute)
{
$value = $validator->getValue($attribute);
if (!filter_var($value, FILTER_VALIDATE_IP, FILTER_FLAG_IPV4 | FILTER_FLAG_IPV6)) {
$message = $this->getOption('message');
if (!$message) {
$message = 'The IP is not valid';
}
$validator->appendMessage(new Message($message, $attribute, 'Ip'));
return false;
}
return true;
}
}自定義model層級的validator:
<?php
use Phalcon\Mvc\Model\Validator,
Phalcon\Mvc\Model\ValidatorInterface;
class MaxMinValidator extends Validator implements ValidatorInterface
{
public function validate($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 the right range of values",
$field,
"MaxMinValidator"
);
return false;
}
return true;
}
}
