Custom PHP validation library - developed by Ixudra.

This package provides a wide variety of validation rules for PHP web applications. These rules can be used to easily validate user input to make sure that it meets the requirements that you have set.

Please also note that this package is intended for, but not exclusive to the Laravel framework. This basically means that most validation methods are universally usable in any PHP application but some make use of internal Laravel components (e.g. see UserValidationTrait). These methods will probably not work correctly unless you also include the used dependencies in you application as well.

This package can be used by anyone at any given time, but keep in mind that it is optimized for my personal custom workflow. It may not suit your project perfectly and modifications may be in order.

Installation

Pull this package in through Composer.

{

    "require": {
        "ixudra/validation": "1.*"
    }

}

Laravel usage

To use this package with Laravel 4 or 5, you will have to extend the default validator class. Once this class is created, you can include the traits into the class to make use of the validation methods. Laravel will automatically pick up the validation rules and make them available to you. Note that you don't have to include all traits if you don't want to. All validation rules are completely independent, which allows for maximum customization.

    use Ixudra\Validation\DateValidationTrait;
    use Ixudra\Validation\TimeValidationTrait;
    use Ixudra\Validation\ArrayValidationTrait;
    use Ixudra\Validation\PasswordValidationTrait;
    use Ixudra\Validation\CoordinateValidationTrait;

    class CustomValidator extends \Illuminate\Validation\Validator {

        use DateValidationTrait;
        use TimeValidationTrait;
        use ArrayValidationTrait;
        use PasswordValidationTrait;
        use CoordinateValidationTrait;

    }

Next, you will need to add the following to your routes.php to let Laravel know that you want to use your custom validator class instead of the default one:

    Validator::resolver(function($translator, $data, $rules, $messages)
    {
        return new CustomValidator($translator, $data, $rules, $messages);
    });

Once this is done, you are all set to go. You can now include the custom validation rules in the same way you use the default rules that Laravel already provides to you:

    $attributes = array(
        'att1'              => 'john.doe@gmail.com',
        'att2'              => 0,
        'att3'              => date('Y-m-d', strtotime('next week'))
    );

    $rules = array(
        'att1'              => 'required|email',
        'att2'              => 'required|truthy',
        'att3'              => 'required|future'
    );

    $validator = Validator::make( $attributes, $rules );
    $validator->fails();
