Slim Framework Request Validation
=================================

[](#slim-framework-request-validation)

A **Request** validation library for the Slim 4 Framework. It uses the [respect/validation](https://github.com/Respect/Validation) library.

This repository is a fork of `https://github.com/benycode/slim-request-validation`.

Install
-------

[](#install)

Via Composer

```
$ composer require semhoun/slim-request-validation
```

Requires PHP 8.5+ and Slim 4.

Compatibility
-------------

[](#compatibility)

- PHP: `^8.5`
- Slim Framework: `^4.15`
- `respect/validation`: `^3.1`
- `slim/psr7`: `^1.7 || ^2.0`
- `phpunit/phpunit` for development: `^12.0 || ^13.0`

Usage
-----

[](#usage)

Create a **Rule** class:

```
use BenyCode\Slim\Validation\Rule\RequestValidationRuleInterface;
use Respect\Validation\ValidatorBuilder as v;

final class AnyRuleClass implements RequestValidationRuleInterface
{
    public function rules(): array
    {
        return [
            'name' => v::alpha(),
            'url' => v::url(),
        ];
    }

    public function messages(): array
    {
        return [
            'url' => 'url must be a URL',
        ];
    }
}
```

With `respect/validation` 3.x, validators are built with `Respect\Validation\ValidatorBuilder` instead of the older static `Validator` API.

Add the middleware to a route:

```
use BenyCode\Slim\Validation\RequestValidation;
use BenyCode\Slim\Validation\Middleware\RequestValidationExceptionMiddleware;
use BenyCode\Slim\Validation\Transformer\RequestValidatorTransformFactory;
use BenyCode\Slim\Validation\Encoder\JsonEncoder;
use Slim\Factory\AppFactory;

$app = AppFactory::create();

$app->post('/api/any_end_point', function ($request, $response) {
    return $response;
})
    ->add(new RequestValidationExceptionMiddleware(new RequestValidatorTransformFactory(), new JsonEncoder()))
    ->add(new RequestValidation([
        new AnyRuleClass(),
    ]));

$app->run();
```

Keep your code clean and split rules across classes when needed:

```
use BenyCode\Slim\Validation\RequestValidation;
use BenyCode\Slim\Validation\Middleware\RequestValidationExceptionMiddleware;
use BenyCode\Slim\Validation\Transformer\RequestValidatorTransformFactory;
use BenyCode\Slim\Validation\Encoder\JsonEncoder;
use Slim\Factory\AppFactory;

$app = AppFactory::create();

$app->post('/api/any_end_point', function ($request, $response) {
    return $response;
})
    ->add(new RequestValidationExceptionMiddleware(new RequestValidatorTransformFactory(), new JsonEncoder()))
    ->add(new RequestValidation([
        new AnyRuleClass(),
        new AppendedRuleClass(),
        new AppendedRule2Class(),
        new AppendedRule3Class(),
    ]));

$app->post('/api/any_end_point2', function ($request, $response) {
    return $response;
})
    ->add(new RequestValidationExceptionMiddleware(new RequestValidatorTransformFactory(), new JsonEncoder()))
    ->add(new RequestValidation([
        new AnyRuleClass(),
        new AppendedRule3Class(),
    ]));

$app->run();
```

Testing
-------

```
