Igni Validation
Licensed under MIT License.
Igni validation is simple, lightweight and extensible validation library.
Installation
composer install igniphp/validation
Introduction
Basic example
<?php use Igni\Validation\Assertion; $numberValidator = Assertion::number($min = 0); $numberValidator->validate(1);// true $numberValidator->validate(-1);// false $numberValidator->validate(1.0);// true $numberValidator->validate('a'); // false
Getting error information
Allows to validate complex arrays
<?php use Igni\Validation\Assertion; use Igni\Validation\Error; $userValidator = Assertion::group([ 'name' => Assertion::alnum(), 'age' => Assertion::number(1, 200), 'email' => Assertion::email(), 'address' => Assertion::text(), ]); $userValidator->validate([ 'name' => 'John', 'age' => 233, 'email' => 'johnmail', ]);// false $errors = $userValidator->getErrors(); $errors[0] instanceof Error\OutOfRangeError;// true $errors[0]->getContext()->getName();//age $errors[1] instanceof Error\EmptyValueError;// true $errors[1]->getContext()->getName();//address // Exception can also be factored out of failure instance throw $errors[0]->toException();

Assertion::alnum(int $min = null, int $max = null)
Creates validator that checks if passed value contains only digits and letters.
Parameters
$min
defines minimum length$max
defines maximum length
Example
<?php use Igni\Validation\Assertion; $validator = Assertion::alnum($minLength = 2); var_dump($validator->validate('a1')); // true
Assertion::alpha(int $min = null, int $max = null)
Creates validator that checks if passed value contains only letters.
Parameters
$min
defines minimum length$max

<?php use Igni\Validation\Assertion; $validator = Assertion::alpha($minLength = 2); var_dump($validator->validate('aaa')); // true

Example
<?php use Igni\Validation\Assertion; $validator = Assertion::boolean(); var_dump($validator->validate(false)); // true
Assertion::chain(Rule ...$rules)
Creates validator that uses other validators to perform multiple validations on passed value.

<?php use Igni\Validation\Assertion; $validator = Assertion::chain(Assertion::text(), Assertion::date()); var_dump($validator->validate('2018-09-10')); // true
Assertion::contains(string $value)
Creates validator that checks if passed string is contained in the validated string.

<?php use Igni\Validation\Assertion; $validator = Assertion::contains('example'); var_dump($validator->validate('Test example')); // true
Assertion::date(string $format = null, $min = null, $max = null)
Creates validator that checks if passed value is valid date.
Parameters
$format
restricts format of passed value$min
defines minimum date range$max
defines maximum date range
Example
<?php use Igni\Validation\Assertion; $validator = Assertion::date('Y-m-d'); var_dump($validator->validate('2018-09-10')); // true
Assertion::email()
Creates validator that checks if passed value is valid email address.
Example
<?php use Igni\Validation\Assertion; $validator = Assertion::email(); var_dump($validator->validate('test@test.com')); // true
Assertion::each(Validator $validator)
Creates validator that checks if each item in passed set can be successfully validated against $validator
.
Parameters
$validator
validator used for each item of the passed set.
Example
<?php use Igni\Validation\Assertion; $validator = Assertion::each(Assertion::date('Y-m-d')); var_dump($validator->validate(['2019-01-01', '2018-10-11'])); // true
Assertion::falsy()
Creates validator that checks if passed value is valid falsy expression;
off
no
false
- 0
Example
<?php use Igni\Validation\Assertion; $validator = Assertion::falsy(); var_dump($validator->validate('no')); // true
Assertion::group(array $validatorsHash)
Creates validator with key/value hash that validates other hashes.
Example
<?php use Igni\Validation\Assertion; $validator = Assertion::group([ 'email' => Assertion::email(), 'password' => Assertion::text(), 'date_of_birth' => Assertion::date('Y-m-d'), ]); var_dump($validator->validate([ 'email' => 'test@domain.com', 'password' => 'secret', 'date_of_birth' => '2019-01-01', ])); // true
Assertion::regex(string $pattern)
Creates validator that checks if passed string matches the pattern.
Example
<?php use Igni\Validation\Assertion; $validator = Assertion::regex('^-[a-z]+$'); var_dump($validator->validate('-aa')); // true
Assertion::truthy()
Creates validator that checks if passed value is valid truthy expression;

yes
Example
<?php use Igni\Validation\Assertion; $validator = Assertion::truthy(); var_dump($validator->validate('yes')); // true
Assertion::text(int $minLength = null, int $maxLength = null)
Creates validator that checks if passed value is string.
Parameters

Creates validator that accepts every non empty string.
Assertion::group(array $validators)
Creates validator that validates passed value by group of defined validators.

Creating custom validator
To create custom validator we have to simply extend \Igni\Validation\Assertion
class, please consider following example:
<?php declare(strict_types=1); use Igni\Validation\Assertion; class ValidateIn extends Assertion { public function __construct(...$values) { $this->attributes['valid_values'] = $values; } protected function assert($input): bool { return in_array($input, $this->attributes['valid_values'], $strict = true); } }
That's all folks!
