Lithe Validator

A simple validation class for PHP designed to validate various types of input data according to specified rules.

Installation

You can install the Lithe Validator module via Composer. Run the following command in your project directory:

composer require lithemod/validator

Usage

Step 1: Include Autoloader

Make sure to include the Composer autoloader in your PHP script:

require 'vendor/autoload.php';

Step 2: Initialize the Validator

Create an instance of the Validator class by passing the data and the validation rules you want to apply.

use Lithe\Base\Validator;

$data = [
    'email' => 'example@example.com',
    'name' => 'John Doe',
    'age' => '25',
];

$rules = [
    'email' => 'required|email',
    'name' => 'required|name',
    'age' => 'required|integer|min:18|max:65',
];

$validator = new Validator($data, $rules);

Step 3: Check Validation

You can check if all validation rules pass using the passed() method:

if ($validator->passed()) {
    echo "Validation passed!";
} else {
    echo "Validation failed!";
    print_r($validator->errors());
}
