The Laravel-like data validator

The Laravel-like Validator is a PHP validation library designed to help you validate data structures with ease. It supports various validation rules, custom rules, and nested data validation.

Installation

You can install the package via Composer:

composer require azolee/validator

Usage

For a complete list of available validation rules, please refer to the Validation Rules document.

Basic Usage

To use the validator, you need to define your validation rules and the data to be validated. Then, call the Validator::make method.

use Azolee\Validator\Validator;

$validationRules = [
    'user.name' => 'string',
    'user.age' => 'numeric',
    'user.is_active' => 'boolean',
    'address' => 'array',
    'address.city' => 'string',
    'address.street' => ['string', 'not_equals_field:address.city', 'not_equals_field:address.street2', 'not_equals_field:address.no'],
    'address.street2' => 'not_null',
    'address.no' => 'string',
    'images.*.url' => 'string',
    'images.*.role' => 'string',
];

$dataToValidate = [
    'user' => [
        'name' => 'John Doe',
        'age' => 30,
        'is_active' => true,
    ],
    'address' => [
        'city' => 'New York',
        'street' => 'First Avenue',
        'street2' => '',
        'no' => '52A',
    ],
    'images' => [
        [
            'url' => 'image1.jpg'
            'role' => 'profile_photo',
        ],
        [
            'url' => 'image2.jpg'
            'role' => 'album_photo',
            'description' => 'This is a photo of me.',
        ],
    ],
];

$result = Validator::make($validationRules, $dataToValidate);

if ($result->isFailed()) {
    echo "Validation failed!";
    print_r($result->getFailedRules());
} else {
    echo "Validation passed!";
}

Custom Rules

You can also define custom validation rules using closures.

$validationRules = [
    'user.name' => [
        function ($data) {
            return $data !== 'John Doe';
        },
        'string',
    ],
];

$dataToValidate = [
    'user' => [
        'name' => 'John Smith'
    ],
];

$result = Validator::make($validationRules, $dataToValidate);

if ($result->isFailed()) {
    echo "Validation failed!";
    print_r($result->getFailedRules());
} else {
    echo "Validation passed!";
}

Exception Handling

The validator can throw exceptions for invalid rules or data if the silent parameter is set to false.

use Azolee\Validator\Exceptions\InvalidValidationRule;
use Azolee\Validator\Exceptions\ValidationException;

try {
    $validationRules = [
        'name' => 123, // Invalid rule
    ];
    $dataToValidate = [
        'name' => 'John Doe',
    ];

    Validator::make($validationRules, $dataToValidate, false);
} catch (InvalidValidationRule $e) {
    echo "Caught an InvalidValidationRule exception: " . $e->getMessage();
} catch (ValidationException $e) {
    echo "Caught a ValidationException: " . $e->getMessage();
}

Testing

To run the tests, use PHPUnit:
