README

A PHP package for validating GTIN codes for use in plain PHP and in Laravel.

Installation

You can install the package via composer:

composer require juststeveking/gtin-php

Usage PHP

If you are using a framework other than Laravel, or Laravel itself - you can use the Gtin class directly to validate aspects or the entire value passed in. You can check out the specifications for gtin and GS1 here.

Validating correct length

A GTIN is between 8 and 14 characters long.

use JustSteveKing\GtinPHP\Gtin;

$correct = 614141999996;
$valid = Gtin::length($correct); // returns true

$incorrect = 123456;
$failed = Gtin::length($incorrect); // returns false

Validating that it is an integer

A GTIN must be an integer value, in php you can easily use is_int() however I have provided a method here to also do the same thing:

use JustSteveKing\GtinPHP\Gtin;

$correct = 614141999996;
$valid = Gtin::integer($correct); // returns true

$incorrect = '614141999996';
$failed = Gtin::integer($incorrect); // returns false

Inspecting the gtin and validating the check digit

The GTIN is formatted in a very specific way, this is documented fully in the specificas document

use JustSteveKing\GtinPHP\Gtin;

$correct = 614141999996;
$valid = Gtin::inspect($correct); // returns true

$incorrect = 123456789;
$failed = Gtin::inspect($incorrect); // returns false

Validating all aspects in one go

use JustSteveKing\GtinPHP\Gtin;

$correct = 614141999996;
$valid = Gtin::validate($correct); // returns true

$incorrect = 123456789;
$failed = Gtin::validate($incorrect); // returns false

Validating in Laravel

There is a Laravel Rule as well as a validation macro that gets registered with this package, please use in one of the following ways:

// using the class directly
public function rules()
{
    return [
        'gtin' => [
            'required',
            new JustSteveKing\GtinPHP\Rules\Gtin,
        ]
    ];
}

// using the registered macro
public function rules()
{
    return [
        'gtin' => [
            'required',
            Rule::gtin(),
        ]
    ];
}

Feel free to use the Gtin class directly if that is more convinient.
