ProductValidation
=================

[](#productvalidation)

ProductValidator is a simply utility for Shopping cart software or custom projects to validate product codes.

Supports UPC-A, UPC-E 6, 7 and 8, EAN13 and ISBN10/ISBN13.

This software is free to use, distribute and change as you see fit according to the MIT Variant license.

**Composer Ready**

Available on Packagist:

#### Sample Usage

[](#sample-usage)

Simply import the `ProductValidator.class.inc` main class file if you are not utilizing auto loaders.

```
require '/ProductValidator.class.inc';

```

To use the validator, you can simply call its `checkCode($code)` method:

```
$result = ProductValidator\ProductValidator::checkCode('1560213639');

var_dump($result);

```

`checkCode` attempts to smartly detect the codes type and returns and array containing the code `type`, (UPC, EAN, ISBN) the `checkDigit` for the code, and the `isbn` pieces if the code is an ISBN.

#### Individual Code Validation

[](#individual-code-validation)

To validate (TRUE|FALSE) a code you already know the type of, use **ProductValidator**'s individual check functions:

```
var_dump(ProductValidator\ProductValidator::checkUpc('748196000441');
var_dump(ProductValidator\ProductValidator::checkEan('9781560213635');
var_dump(ProductValidator\ProductValidator::checkIsbn('1560213635');

```

`checkUpc`, `checkEan` and `checkIsbn` return TRUE if the check digit and code validates, or FALSE if they do not.

#### Validators

- UpcValidator
- EanValidator
- IsbnValidator
