No Captcha, no questions, no counting animals, no puzzles, no math.

Requirements

• Yii 2.0 or above
• CleanTalk account https://cleantalk.org/register?product=anti-spam

##Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist cleantalk/yii2-antispam

or add

"cleantalk/yii2-antispam": "~1.0.0"

to the require section of your composer.json.

##Usage

1. Get access key on https://cleantalk.org/register?platform=yii2

2. Open your application configuration in protected/config/web.php and modify components section:

// application components
'components'=>[
    ...
        'antispam' => [
            'class' => 'cleantalk\antispam\Component',
            'apiKey' => 'Your API KEY',
        ],
    ...
],

3. Add validator in your model, for example ContactForm:

namespace app\models;

use cleantalk\antispam\validators\MessageValidator;
use Yii;
use yii\base\Model;

/**
 * ContactForm is the model behind the contact form.
 */
class ContactForm extends Model
{
    public $name;
    public $email;
    public $body;
    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            // name, email, subject and body are required
            [['name', 'email', 'subject', 'body'], 'required'],
            // email has to be a valid email address
            ['email', 'email'],
            ['body', MessageValidator::className(), 'emailAttribute'=>'email', /*'nickNameAttribute'=>'name'*/]
        ];
    }
}

4. In form view add widget for hidden Javascript checks:

<?php $form = ActiveForm::begin(); ?>
    ...
    <?= \cleantalk\antispam\Widget::widget()?>
    ...
    <?= Html::submitButton('Submit')?>
    ...
<?php ActiveForm::end(); ?>

User registration validator

Example rules:

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['name', 'email'], 'required'],
            ['email', 'email'],
            ['email', UserValidator::className(), 'nickNameAttribute'=>'name']
