Validate php variables, simple and extensible

PHP variable validation.

Use provided validators or easily create your own.

Usage

<?php
    namespace YourNameSpace;
    
    require_once "vendor/CodeHipster/validation/validators/InRange.class.php";
    use Validation\validators\InRange;

    require_once "YourValidator.php";
    
    $custom_messages = array(
        "Exists"=>"Variable cannot be null.",
        "IsNumeric"=>"Variable is not a number",
        "Max"=>"Variable is greater than maximum",
        "Min"=>"Variable is smaller than minimum",
        "YourValidator"=>"Custom YourValidator message");

    $in_range_validator = new InRange(3, 6, $custom_messages);
    $your_validator = new YourValidator($custom_messages);

    var_dump($in_range_validator->validate(8));
    var_dump($your_validator->validate("some_value"));
?>

Custom validator

A validator is composed of one or more parts. Extend the Validator class or create your implementation of an iValidator

A part is just a validation method. Usually you can just extend Validator and implement an iValidatorPart.

<?php
    namespace YourNameSpace;

    require_once "vendor/CodeHipster/validation/Validator.class.php";
    use Validation\Validator;
    
    require_once "vendor/CodeHipster/validation/iValidatorPart.interface.php";
    use Validation\iValidatorPart;
    
    require_once "vendor/CodeHipster/validation/validators/Exists.class.php";
    use Validation\validators\Exists;
    
    require_once "vendor/CodeHipster/validation/ValidatorPart.class.php";
    use Validation\ValidatorPart;
        
    class YourValidatorPart extends ValidatorPart{
        
        function __construct($message = null){
            parent::__construct($message ?? "default message");
        }
        
        public function validate_method($var){
            if($var == "some_value"){
                return $this->fail_message;
            }
            else{
                return null;
            }           
        }
    }

    class YourValidator extends Validator {

        function __construct($messages = null){
            $exists_validator = new Exists($messages);
            $your_part = new YourValidatorPart($messages["YourValidator"]);
            parent::__construct($your_part, ...$exists_validator->get_parts());
        }
    }
?>
