Usage

The PHP Validator library is designed to be extremely user-friendly and modular, allowing you to validate data in a way that suits your application's needs. Whether you're validating simple data fields or complex nested arrays, PHP Validator provides an intuitive API that makes data validation straightforward.

Example 1: Simple Validator for Basic Data

In this example, we demonstrate how to set up a simple validator for basic data fields such as age, website_ids, and email. Each field has its own set of validation rules, ensuring that the data meets your application's requirements.

<?php
require __DIR__ . '/vendor/autoload.php';

use OpenVoid\Validator\Validator;
use OpenVoid\Validator\Validators\ArrayValidator;
use OpenVoid\Validator\Validators\EmailValidator;
use OpenVoid\Validator\Validators\Integer;
use OpenVoid\Validator\Validators\NotNull;

$validator = new Validator([
    "age"         => [(new Integer())->min(18)->max(99)],
    "website_ids" => [(new ArrayValidator([new Integer(), new NotNull()]))->not_empty()],
    "email"       => new EmailValidator(),
]);

$is_validated = $validator->validate([
    "age"         => 24,
    "website_ids" => [1, 2],
    "email"       => "antonio@obradovic.dev",
]);

if ($is_validated) {
    // * Process form
} else {
    // * Handle errors
    $errors = $validator->get_errors();
}

Example 2: Validating your form data

In a real-world scenario, you often need to validate data submitted through forms. This example shows how to validate POST data by defining validation rules for each form field. Simply pass the entire $_POST object into the validate method and let the library handle the rest.

<?php
require __DIR__ . '/vendor/autoload.php';

use OpenVoid\Validator\Validator;
use OpenVoid\Validator\Validators\EmailValidator;
use OpenVoid\Validator\Validators\NotNull;

$validator = new Validator([
    "email" => [new EmailValidator(), new NotNull()],
]);

$is_validated = $validator->validate($_POST);

if ($is_validated) {
    // * Process form
} else {
    // * Handle errors
    $errors = $validator->get_errors();
}
