A simple validation library

Flikore Validator is a validation library for PHP aimed to be simple, powerful, object oriented and extensible. It also focus on code and objects reuse, both in the library itself and in the projects that rely on the Validator.

There are many others validators for PHP, of course. Respect/Validation, for example, is very thorough and has a lot of validators ready to be used. The system for error messages, however, is problematic and was one of the reasons for Flikore Validator to arise. Valitron is very simple and minimalistic, but it validates only arrays (not single values) and doesn't work with objects like Respect and Flikore do.

Instalation

Composer

Composer is the preferred method to install this validator. Simply add to your composer.json:

{
    "require": {
        "flikore/validator": "dev-master"
    }
}

Run composer install, then include the autoload file in your project:

<?php

require_once 'vendor/autoload.php';

// Do validation stuff

Installing with Git

Clone this repository in a folder on your project:

git clone https://github.com/flikore/validator.git vendor/flikore/validator

Include the autoload.php file in the bootstrap for your project:

<?php
    
require_once 'vendor/flikore/validator/autoload.php';

// Do validation stuff

An alternative is to create a submodule instead of cloning the repository. This way you don't need to push this library to your own repository and can also update it more easily:

git submodule add https://github.com/flikore/validator.git vendor/flikore/validator

Download

You can also download the tarball (or the zipball) and set it up in one of your project folders.

How to use

To show how simple it is to use, see the following example:

<?php

require 'autoload.php';

use Flikore\Validator\Validators as v;

// Instantiate an existing validator
$v = new v\ExactValueValidator(5);

// Use the "validate" method to check if a value is valid
var_dump($v->validate(5));    // bool(true)

// And you can use the same validator object as many times as you want
var_dump($v->validate(4));    // bool(false)
var_dump($v->validate(0));    // bool(false)

For more examples and information, see the usage page.

Also, see the examples folder, as it shows most (if not all) of the features.

Extensibility

New validators can be added simply by extending the base class.

<?php

require 'autoload.php';

use Flikore\Validator\Validators as v;

class PerfectSquareValidator extends Flikore\Validator\Validator
{
    protected function doValidate($value)
    {
        return is_numeric($value) && (floor(sqrt($value)) * floor(sqrt($value)) 
                == ((int)$value));
    }

}

$v = new PerfectSquareValidator();

var_dump($v->validate(25));   // bool(true)
var_dump($v->validate(30));   // bool(false)
var_dump($v->validate('36')); // bool(true)

Available validators

Currently, there are the following validator classes (click to see the API documentation):
