Dirthara Validation

Dirthara Validation checks an input array against rules per field and returns every error with the path of the field that caused it. Rules are small immutable objects, and nested input is validated by composing rules rather than by writing dotted field names.

use Dirthara\Validation\Rule\Collection\Each;
use Dirthara\Validation\Rule\Text\Email;
use Dirthara\Validation\Rule\Structure\Nested;
use Dirthara\Validation\Rule\Presence\Required;
use Dirthara\Validation\ValidatorFactory;

$factory = new ValidatorFactory();

$validator = $factory->create([
    'email' => [new Required(), new Email()],
    'contacts' => new Each(new Nested($factory->create([
        'email' => [new Required(), new Email()],
    ]))),
]);

$result = $validator->validate([
    'email' => 'ada@example.com',
    'contacts' => [['email' => 'grace@example.com'], ['email' => 'invalid']],
]);

$result->valid();              // false
$result->errors[0]->field;     // 'contacts.1.email'
$result->errors[0]->message;   // 'contacts.1.email must be a valid email address'

• Validating input covers the factory, rules per field, and how missing values are handled.
• Rules lists the rules the package ships and how to write your own.
• Results and errors describes what a validation returns.
• Error handling lists the exceptions the package throws.
