Laravel Validator

Instalation

composer require nimaebrazi/laravel-validator

If using laravel 5.4.* and older version you nedd add service provider in config/app.php

'providers' => [
    ...
    \nimaebrazi\LaravelValidator\LaravelValidatorServiceProvider::class,
    ...
]

Publish config:

php artisan vendor:publish

You can change message path file in config: laravel_validator.php

Add this key in messages.php file: resources/lang/YOUR_LANGUAGE/messages.php

"validation_failed" => "messages.validation_failed"

This package throws an exception named ValidationException. For handling Laravel Exception, add below code in Handler.php file and custumize it for your project.

use nimaebrazi\LaravelValidator\src\Validator\ValidationException;
use Symfony\Component\HttpFoundation\Response;

...
/**
* Render an exception into an HTTP response.
*
* @param  \Illuminate\Http\Request  $request
* @param  \Exception  $exception
* @return \Illuminate\Http\Response
*/
public function render($request, Exception $exception)
{
    if($exception instanceof ValidationException){
        return response()->json([
            'status' => Response::HTTP_UNPROCESSABLE_ENTITY,
            'description' => $exception->getMessage(),
            'data' => [
                'errors' => $exception->getErrors()
            ]

        ], 422);
    }

  return parent::render($request, $exception);
}

Usage

Step 1:

Create a validation class:

\nimaebrazi\LaravelValidator\Validator\AbstractValidator

public function messages(): array & public function customAttributes(): array methods are optional.

use nimaebrazi\LaravelValidator\Validator\AbstractValidator;

class UpdateUserProfile extends AbstractValidator
{
    /**
     * Rules of validation.
     *
     * @return array
     */
    public function rules(): array
    {
        return [
            'name' => 'required|min:3',
        ];
    }
    
    // OPTIONAL
    /**
     * Messages of rules.
     *
     * @return array
     */
    public function messages(): array
    {
        return [
            //
        ];
    }

    // OPTIONAL
    /**
     * Custom attributes of rules.
     *
     * @return array
     */
    public function customAttributes(): array
    {
        return [
            //
        ];
    }
}

Custom Attributes

Step 2: Inject class to a controller:

class ApiUserController extends Controller
{
    /**
     * @param Request $request
     * @param UpdateUserProfile $validator
     * @throws \Exception
     * @throws \nimaebrazi\LaravelValidator\src\Validator\ValidationException
     */
    public function update(Request $request, UpdateUserProfile $validator)
    {
        $validator->make($request->all())->validate();
    }

Notes:

When you call validate function package throws default exception. If you want handle other way:

class ApiUserController extends Controller
{
    /**
     * @param Request $request
     * @param UpdateUserProfile $validator
     * @throws \Exception
     * @throws \nimaebrazi\LaravelValidator\src\Validator\ValidationException
     */
    public function update(Request $request, UpdateUserProfile $validator)
    {
        $validator->make($request->all());

        if($validator->fails()){
           // your codes
        }
        
        
        if($validator->passes()){
           // your codes
        }
    }

RuleManager Helper

Are you see document when use validator rules? I think it is so hard, when forget a rule and parameters. You can use RuleManager of this package.

use nimaebrazi\LaravelValidator\Validator\AbstractValidator;

class UpdateUserProfile extends AbstractValidator
{
    /**
     * Rules of validation.
     *
     * @return array
     */
    public function rules(): array
    {
        return [
            'name'  => $this->ruleManager()->required()->min('3')->make(),
            'age'   => $this->ruleManager()->required()->numeric()->max('3')->min('0')->make(),
            'other' => $this->ruleManager()->required()->string()->make()        
        ];
    }
}
