Use PHP 8 attributes to implement request data validation

This package provides annotations to easily add validation rules on action methods in a controller. Here's a quick example:

use Bakome\ValidationAttributes\Attributes\ValidationRule;

class ExampleController
{
    #[ValidationRule('title', 'required|string')]
    public function actionMethod()
    {

    }
}

Motivation

This project exists to provide simple and cleaner way to validate request data on Laravel controllers. Using validation rules in action methods often complicate readability of the controller and adding validation in separate requests classes imply switching trough that classes multiple time to view and change the rules (Losing focus). With this simple attributes we can make validation more accessible and maintainable in the controllers without messing the controller code.

Installation

You can install the package via composer:

composer require bakome/laravel-validation-attributes

You can publish the config file with:

php artisan vendor:publish --provider="Bakome\ValidationAttributes\ValidationAttributesServiceProvider" --tag="config"

Usage

The package provides several annotations that should be put on controller action methods. These annotations are used to validate request data.

Adding a validation rule with string as a parameter

use Bakome\ValidationAttributes\Attributes\ValidationRule;

class ExampleController
{
    #[ValidationRule('title', 'required|string')]
    public function actionMethod()
    {

    }
}

This attribute will check if title parameter is present in current request and throw validation error if not present.

Adding a validation rule with an array as a parameter

use Bakome\ValidationAttributes\Attributes\ValidationRule;

class ExampleController
{
    #[ValidationRule('title', ['required', 'string'])]
    public function actionMethod()
    {

    }
}

This attribute will check if title parameter is present in current request and throw validation error if not present.

Adding a multiple validation rules

use Bakome\ValidationAttributes\Attributes\ValidationRule;

class ExampleController
{
    #[ValidationRule('description', 'required|string')]
    #[ValidationRule('title', ['required', 'string'])]
    public function actionMethod()
    {

    }
}

This attribute will check if title and description parameters are present in current request and throw validation error if not present.

Adding a redirect for failed validation

use Bakome\ValidationAttributes\Attributes\ValidationRule;
use Bakome\ValidationAttributes\Attributes\ValidationRuleRedirect;

class ExampleController
{
    #[ValidationRule('description', 'required|string')]
    #[ValidationRule('title', ['required', 'string'])]
    #[ValidationRuleRedirect('/a-redirection-route')]
    public function actionMethod()
    {

    }
}

This attribute will check if title and description parameters are present in current request, compile validation error messages and redirect the page to provided route.

Adding a redirect with input for failed validation

use Bakome\ValidationAttributes\Attributes\ValidationRule;
use Bakome\ValidationAttributes\Attributes\ValidationRuleRedirect;

class ExampleController
{
    #[ValidationRule('description', 'required|string')]
    #[ValidationRule('title', ['required', 'string'])]
    #[ValidationRuleRedirect('/a-redirection-route', true)]
    public function actionMethod()
    {

    }
}

This attribute will check if title and description parameters are present in current request, compile validation error messages and redirect the page to provided route including old input parameters.

Ajax's requests awareness and proper json responses returned for failed validation
