README

Yii Recaptcha extension. This simple extension was built to give developers full control over their recaptcha styling via custom theming.

Please see https://developers.google.com/recaptcha/docs/customization.

Installation

• Install via composer - https://packagist.org/packages/amnah/yii-recaptcha
• OR extract files into vendor dir - protected/vendor/amnah/yii-recaptcha

Usage

• Ensure that you have a model with an appropriate "recaptcha" attribute
• Add path alias (modify path as needed)

Yii::setPathOfAlias('YiiRecaptcha',Yii::getPathOfAlias("application.vendor.amnah.yii-recaptcha"));

• Call widget in view file (take note of the style attribute, as that determines the function it calls)

<?php $this->widget('YiiRecaptcha\Recaptcha', array(
 'model' => $model,
 'attribute' => 'recaptcha',
 'publicKey' => '<recaptcha public key>',
 'style' => 'custom',
)); ?>

/**
 * The styling of the recaptcha widget, which will decide which function to use
 * For example,
 * $style = "default" => $this->runDefault();
 * $style = "custom" => $this->runCustom();
 * @var string
 */

• Add validator to model rules()

public function rules() {
	return array(
		...
		array('recaptcha', 'required'),
 array('recaptcha', 'YiiRecaptcha\RecaptchaValidator', 'privateKey' => '<recaptcha private key>'),
		...
	);
}

Extending

• Create a new file that extends the YiiRecaptcha\Recaptcha or YiiRecaptcha\RecaptchaValidator class
• Reference the new file instead of the original

<?php $this->widget('application.extensions.MyRecaptcha', array(...)); ?>
