yii2-isbn-validator
===================

[](#yii2-isbn-validator)

This extension adds ISBN-10 / ISBN-13 Form validation as a standalone validator to the Yii2 framework.

Installation
------------

[](#installation)

The preferred way to install this extension is through [composer](http://getcomposer.org/download/).

Either run

```
$ php composer.phar require kurdt94/yii2-isbn-validator "@dev"

```

or add

```
"kurdt94/yii2-isbn-validator": "@dev"

```

to the `require` section of your `composer.json` file.

Usage
-----

[](#usage)

This extension extends the `yii\validators\Validator` class to validate ISBN-10 or ISBN-13 identifiers. The `IsbnValidator` class can be applied using the alias `k-isbn` in your model rules. In this example we validate the "isbn\_number" field:

```
use yii\db\ActiveRecord;

class BooksModel extends ActiveRecord {
    /**
     * @return array the validation rules.
     */
    public function rules()
    {
        return [
            //...
            [['isbn_number'], 'k-isbn'],
        ];
    }
}
```

Ajax Validation
---------------

[](#ajax-validation)

Prefered is the use of AjaxValidation. This can be aplied using the ActiveForm `enableAjaxValidation` property.

```
echo $form->field($model, 'isbn_number', ['enableAjaxValidation' => true]);
```

\-- Or if you wish to enable AjaxValidation on the entire Form. --

```
echo $form = ActiveForm::begin(['id' => 'books-form', 'enableAjaxValidation' => true,]);
```

Don't forget to set up Ajax response in your controller-action. If the request `isAjax` and we can `load($_POST)` then return `\yii\widgets\ActiveForm::validate($model)`.

```
$model = new Books();

if (Yii::$app->request->isAjax && $model->load($_POST))
{
    Yii::$app->response->format = 'json';
    return \yii\widgets\ActiveForm::validate($model);
}
```
