Licensed under MIT. Totally free for private or commercial projects.

Installation

composer require andrewdyer/slim3-validator

Usage

use Slim\App;
use Anddye\Validation\Validator;
use Respect\Validation\Validator as v;

$app = new App();

$container = $app->getContainer();

$container['validationService'] = function () {
    return new Validator();
};

$app->get('/', function (Request $request, Response $response) use ($container) {
    $validation = $container['validationService']->validate($request, [
        'email' => v::email()->length(1, 254)->notEmpty(),
        'forename' => v::alpha()->length(1, 100)->notEmpty()->noWhitespace(),
        'password' => v::length(8, 100)->notEmpty(),
        'surname' => v::alpha()->length(1, 100)->notEmpty()->noWhitespace(),
        'username' => v::alnum()->length(1, 32)->notEmpty()->noWhitespace(),
    ]);

    if (!$validation->hasPassed()) {
        // Validation has not passed
    } else {
        // Validation has passed
    }
});

$app->run();

Attach a new instance of Anddye\Validation\Validator; to your applications container so it can be accessed anywhere you need.

$container['validationService'] = function () {
    return new \Anddye\Validation\Validator();
};

You can easily validate your form inputs using the validate() helper. Assign to a variable the validate() method - passing in the $request object as well as an array where the array key represents the name of the field and the array value represents the validation rules.

$validation = $container['validationService']->validate($request, [
    'email' => v::email()->length(1, 254)->notEmpty(),
    'forename' => v::alpha()->length(1, 100)->notEmpty()->noWhitespace(),
    'password' => v::length(8, 100)->notEmpty(),
    'surname' => v::alpha()->length(1, 100)->notEmpty()->noWhitespace(),
    'username' => v::alnum()->length(1, 32)->notEmpty()->noWhitespace(),
]);

Respect\Validation is namespaced, but you can make your life easier by importing a single class into your context:

use Respect\Validation\Validator as v;

You can then check if the validation has passed using the hasPassed() method:

if (!$validation->hasPassed()) {
    // Validation has not passed
} else {
    // Validation has passed
}

If the validation has failed, an array of the validation errors can be accessed by calling the getErrors() method:

foreach ($validation->getErrors() as $input => $errors) {
    foreach ($errors as $error) {
        echo $error;
    }
}
