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": {
    "cgsmith/zf1-recaptcha-2": "~1.0"
}

Usage

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

<?php
// important view settings that you will have to place
$view->headScript()->appendFile('//www.google.com/recaptcha/api.js'); // pulls in google js api

// setup your helper path
$view->addHelperPath('/src/Cgsmith/View/Helper', 'Cgsmith\\View\\Helper\\'); 

// setup prefix path for form element (form abstract) 
$this->addPrefixPath('Cgsmith\\Form\\Element', '/src/Cgsmith/Form/Element', Zend_Form::ELEMENT);
$this->addElementPrefixPath('Cgsmith\\Validate\\', '/src/Cgsmith/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('options')->recaptcha->sitekey,
    'secretKey' => Zend_Registry::get('options')->recaptcha->secretkey,
]);

After you run $form->isValid($post) you will need to run something similar to:

$values = $form->getValues();
unset($values['g-recaptcha-response']);
