Payloads, how name says, are about data. That tradicional model with getters and setters. But, we don't need models anymore. Thanks to (Eloquent Model)[https://laravel.com/docs/8.x/eloquent] which solved that.

But, there are still Request and Response data, they are not any kind of storage data, they are just data. Adopt some kind of ORM Model to them... it's kind of overthinking, making these datas too complex.

This simples library cames to solve it. Payloads are tradicional arrays with more flexibily. Same flexibility we can see at Eloquent Models, but not complicated or overpowerfull at all. It's just a way to standatize dataa across Requests and Responses.

See below how it works.

Usage

use Piggly\Dev\Payload\Person;

$person = [
	'name' => 'John Connor',
	'email' => 'john@skynet.com',
	'phone' => '+1-202-555-0172',
	'address' => [
		'address' => 'Future Avenue',
		'number' => '2047',
		'complement' => 'High Tech World',
		'district' => 'Nobody\'s Alive',
		'city' => 'Unknown',
		'country_id' => 'US',
		'postal_code' => '55372'
	]
];

// Import from an array
$person = (new Person())->import($person);
// Validate (throw an exception if can't)
$person->validate();

// Payload object to array
$_array = $person->toArray();
// Payload object to json
$_json = $person->toJson();
// Alternative way to converto to json
$_json = json_encode($person);

// Serialize
$_serialized = serialize($person);
// Unserialize
$_unserialized = unserialize($_serialized);

PayloadMap

The PayloadMap class force to payload use a map. This mapping will strict define all fields allowed to payload and, even, fields validations. Each field inside a PayloadMap will be a Field object. The Field object will have following properties:

There also methods:

export() will export field value;
validate() will return a boolean which validates field value;
assert() will throw an InvalidDataException if cannot validate field value;
props() set all props once;
back() to navigation purpose it will goes back to PayloadMap object, since Field is inside one.

Creating a PayloadMap works the same way as creating a PayloadArray, but it's required the _map() method, which will contains the mapping to fields:

namespace Piggly\Dev\Payload;

use Piggly\Payload\Exceptions\InvalidDataException;
use Piggly\Payload\PayloadMap;
use Respect\Validation\Validator as v;

class PersonMap extends PayloadMap
{
	/**
	 * This method is called at constructor.
	 * You should use it to setup fields map
	 * with add method.
	 *
	 * @since 1.0.5
	 * @return void
	 */
	protected function _map ()
	{
		$this
			->add('name')
				->required()
				->back()
			->add('email')
				->validator(v::email())
				->required()
				->back()
			->add('phone')
				->validator(v::phone())
				->back()
			->add('address')
				->back();
	}

	/**
	 * Import $input data to payload.
	 * 
	 * @param array $input
	 * @param bool $ignoreInvalid Should ignore invalid data.
	 * @since 1.0.0
	 * @return self
	 * @throws InvalidDataException
	 */
	public function import ( $input, $ignoreInvalid = true )
	{
		$input = is_array( $input ) ? $input : json_decode($input, true);
		return $this->_importArray($input, $ignoreInvalid);
	}

	/**
	 * Mutator for address.
	 *
	 * @param AddressMap|array $address Address.
	 * @since 1.0.0
	 * @return AddressMap
	 */ 
	protected function setterAddress ( $address ) : AddressMap
	{
		if ( !($address instanceof AddressMap) )
		{ $address = (new AddressMap())->import($address); }

		return $address;
	}
}

You may use setter{key}() and getter{key}() methods to mutate field value before set and after get. Mutators, be them setters or getters, should always return the value mutated.
