README

A PHP class for checking EAN8, EAN13, UPC and GTIN barcodes are valid (based on check digit).

https://packagist.org/packages/cedcommerce/validator

Note: This project currently does nothing other than have some validation functions. I expect to add additional functionality in the future.

Installation (with composer)

composer require cedcommerce/validator 

Usage

// Class instantation $barcode = '5060411950139'; $validator = new \Ced\Validator\Barcode(); $validator->setBarcode($barcode); // Check barcode is in valid format if ($validator->isValid()) { echo 'Valid :)'; } else { echo 'Invalid :('; } // Get the barcode type echo 'Barcode is in format of ' . $validator->getType(); // Possible formats returned are: // (string) "GTIN" which equals constant \Ced\Validator\Barcode::TYPE_GTIN // (string) "EAN-8" which equals constant \Ced\Validator\Barcode::TYPE_EAN_8 // (string) "EAN" which equals constant \Ced\Validator\Barcode::TYPE_EAN // (string) "EAN Restricted" which equals constant \Ced\Validator\Barcode::TYPE_EAN_RESTRICTED // (string) "UPC" which equals constant \Ced\Validator\Barcode::TYPE_UPC // (string) "UPC Coupon Code" which equals constant \Ced\Validator\Barcode::TYPE_UPC_COUPON_CODE // Returns the barcode in GTIN-14 format $validator->getGTIN14() // Returns the barcode as entered $validator->getBarcode()
