Encodes and decodes GTIN numbers (EAN-8 and EAN-13) with support for products having variable weight and price.
You can install this package via Composer:
composer require kekos/gs1
Each member country of GS1 have their own specification for products with variable weight and price, magazines and coupons. This is handled by this library by defining encoding rules in "locales".
Currently only the Sweden locale is implemented.
Start by creating an entity:
$entity = new \Gs1\Entity\WeightProduct($sku, $weight);
$entity = new \Gs1\Entity\PriceProduct($sku, $price);
$entity = new \Gs1\Entity\Publication($sku, $price);
$entity = new \Gs1\Entity\Coupon($id, $discount);Use GtinFactory class by specifying which locale to use:
$code = \Gs1\GtinFactory::get('Sweden', $entity);
echo $code;Create a GTIN entity:
$gtin = new \Gs1\Gtin\Gtin13($code);
$gtin = new \Gs1\Gtin\Gtin8($code);Use EntityFactory class by specifying which locale to use:
$entity = \Gs1\EntityFactory::get('Sweden', $gtin);
if ($entity instanceof \Gs1\Entity\WeightProduct) {
echo 'Weight: ' . $entity->getWeight();
}$product = new \Gs1\Entity\Product($sku, $company_prefix);
$product->getSku();
$product->setSku($sku);
$product->getCompanyPrefix();
$product->setCompanyPrefix($company_prefix);$product = new \Gs1\Entity\WeightProduct($sku, $weight);
$product->getSku();
$product->setSku($sku);
$product->getWeight();
$product->setWeight($weight);$product = new \Gs1\Entity\PriceProduct($sku, $price);
$product->getSku();
$product->setSku($sku);
$product->getPrice();
$product->setPrice($price);$coupon = new \Gs1\Entity\Coupon($id, $value);
$coupon->getId();
$coupon->setId($id);
$coupon->getValue();
$coupon->setValue($value);$publication = new \Gs1\Entity\Publication($sku, $price);
$publication->getSku();
$publication->setSku($sku);
$publication->getPrice();
$publication->setPrice($price);When setting the code you don't have to specify the checksum (digit 8 or 13).
The Gtin classes will add the checksum automatically if needed.
$gtin = new \Gs1\Gtin\Gtin8($code);
// ...or
$gtin = new \Gs1\Gtin\Gtin13($code);
$gtin->getCode();
$gtin->setCode($code);
$gtin->isValid(); // true or false
$gtin->getChecksum();
$gtin->__toString(); // magic methodReport bugs in GitHub issues or feel free to make a pull request :-)
