ZF1 reCAPTCHA2 - Google reCAPTCHA integration

ZF1 ships with Google reCAPTCHA version 1. Now that version 2 is available you will probably want to use an up-to-date element for your Zend Framework installations.

Installation

Composer Install

"require": {
    "wendrowycz/zf1-recaptcha-2": "~1.0"
}

Usage

Install the latest version (1.0.1) and setup your plugins and form abstract with the following information:

• On your application.ini or where you want

recaptcha.sitekey = "YOUR SITE KEY GIVED BY GOOGLE"
recaptcha.secretkey = "YOUR SECRET KEY GIVED BY GOOGLE"

• In your controller:

<?php
$this->view->headScript()->appendFile('//www.google.com/recaptcha/api.js'); 
$this->view->addHelperPath(APPLICATION_PATH . 'Wendrowycz', 'Wendrowycz');

• In the init() function of your Form

 $this->addPrefixPath('Wendrowycz\\Form\\Element', APPLICATION_PATH . '/../vendor/wendrowycz/zf1-recaptcha-2/src/Wendrowycz/Form/Element', Zend_Form::ELEMENT);
 $this->addElementPrefixPath('Wendrowycz\\Validate\\', APPLICATION_PATH . '/../vendor/wendrowycz/zf1-recaptcha-2/src/Wendrowycz/Validate/', Zend_Form_Element::VALIDATE);

• Below is what you would setup in your form.

<?php

// create your element and pass through your site key and secret key
$this->addElement('Recaptcha', 'g-recaptcha-response', [
    'siteKey'   => Zend_Registry::get('application')->recaptcha->sitekey,
    'secretKey' => Zend_Registry::get('application')->recaptcha->secretkey,
]);

• On your controller, after "validate the post data"

if($form->isValid($_POST)) {
	$values = $form->getValues();
	unset($values['g-recaptcha-response']);
	// Your business logic must be here
}
