case-insensitive validation using phalcon validation class

In validation class my intiialize function is like this

public function initialize()
{
    $this->add('gender',new InclusionIn(array(
           'message' => 'Please enter a valid Gender',
           'domain' => array('Male','Female'),
           'case_insensitive' => false
    )));
}

Problem is, InclusionIn makes a case-sensitive validation so if user enter "male" application throws an error Please enter a valid Gender. I want this validation should be case-insensitive but I did not find any way to do it.

You can now use filter see phalcon Filtering and Sanitizing https://docs.phalconphp.com/en/latest/reference/filter.html

In controller like this: note filter need to be added to services initialisation

$gender = $this->filter->sanitize($gender, "lower");

OR

In your customValidation class:

class MyValidation extends Validation 
{
    public function initialize()
    {
       $this->add('gender',new InclusionIn(array(
         'message' => 'Please enter a valid Gender',
         'domain' => array('male','female'),
       )));

       $this->setFilters('gender', 'lower');
    }
}

In case of validating model, you can use beforeValidation(), beforeValidationOnCreate() or beforeValidationOnUpdate() to lowercase/uppercase value:

function beforeValidation() {
    $this->gender = ucfirst($this->gender);
}

If validating via Forms, you can apply addFilter(lower) and validate for lowercase eg.

As @M2sh & @honerlawd guided, finally I ended with writing a new validator for 'inclusion` sharing the code here

<?php

namespace library\app\validators;

use Phalcon\Validation;
use Phalcon\Validation\Validator;
use Phalcon\Validation\Exception;
use Phalcon\Validation\Message;

class InclusionIn extends Validator
{

    /**
     * Executes the validation
     */
    public function validate(Validation $validation, $attribute)
    {

        $value = $validation->getValue($attribute);

        if ($this->isSetOption("allowEmpty") && empty($value)) {
            return true;
        }

        /**
         * A domain is an array with a list of valid values
         */
        $domain = $this->getOption("domain");
        if (!is_array($domain)) {
            throw new Exception("Option 'domain' must be an array");
        }
        $refinedDomain = array_map('strtolower', $domain);

        $strict = false;
        if ($this->isSetOption("strict")) {
            if (!is_bool($strict)) {
                throw new Exception("Option 'strict' must be a boolean");
            }

            $strict = $this->getOption("strict");
        }

        /**
         * Check if the value is contained by the array
         */
        if (!in_array(strtolower($value), $refinedDomain, $strict)) {

            $label = $this->getOption("label");
            if (empty($label)) {
                $label = $validation->getLabel($attribute);
            }

            $message = $this->getOption("message");
            $replacePairs = ['field' => $label, 'domain' => join(", ", $domain)];
            if (empty($message)) {
                $message = $validation->getDefaultMessage("InclusionIn");
            }

            $validation->appendMessage(new Message(strtr($message, $replacePairs), $attribute, "InclusionIn"));
            return false;
        }

        return true;
    }

}

InclusionIn uses in_array which is case sensitive. You would have to write your own Validator in order to get the functionality you would need. Here is the implementation of the class so you can see what options are available.

Another option is just to format the input before the validator is fired. e.g. if they type in male or MALE convert it to Male so the validation will pass.
