README
This is a Object Oriented PHP port of the original ReCaptcha lib.
It's been designed to be testable and uses Guzzle as a transport layer.
Install
The recommended way to use ReCaptcha is through composer.
{ "require": { "neutron/recaptcha": "~0.1.0" } }
Silex Service Provider
A simple Silex service provider :
use Neutron\ReCaptcha\ReCaptcha; use Neutron\ReCaptcha\ReCaptchaServiceProvider; use Silex\Application; $app = new Application(); $app->register(new ReCaptchaServiceProvider(), array( 'recaptcha.public-key' => 'fdspoksqdpofdkpopgqpdskofpkosd', 'recaptcha.private-key' => 'lsdmkzfqposfomkcqdsofmsdkfkqsdmfmqsdm', )); // $captcha is an instance of Neutron\ReCaptcha\Response $captcha = $app['recaptcha']->bind($app['request']); if ($captcha->isValid()) { echo "YEAH !"; } else { echo "Too bad dude :( " . $captcha->getError(); }
Usage Example
To display a captcha to the client :
- Initialize your captcha object :
use Neutron\ReCaptcha\ReCaptcha; $recaptcha = ReCaptcha::create($publicKey, $privateKey);
- In your template :
<script type="text/javascript"> var RecaptchaOptions = { theme : 'custom', custom_theme_widget: 'recaptcha_widget' }; </script> <form method="post"> <div id="recaptcha_widget" style="display:none"> <div id="recaptcha_image"></div> <div class="recaptcha_only_if_incorrect_sol" style="color:red">Incorrect please try again</div> <span class="recaptcha_only_if_image">Enter the words above:</span> <span class="recaptcha_only_if_audio">Enter the numbers you hear:</span> <input type="text" id="recaptcha_response_field" name="recaptcha_response_field" /> <div><a href="javascript:Recaptcha.reload()">Get another CAPTCHA</a></div> <div class="recaptcha_only_if_image"><a href="javascript:Recaptcha.switch_type('audio')">Get an audio CAPTCHA</a></div> <div class="recaptcha_only_if_audio"><a href="javascript:Recaptcha.switch_type('image')">Get an image CAPTCHA</a></div> <div><a href="javascript:Recaptcha.showhelp()">Help</a></div> </div> <script type="text/javascript" src="http://www.google.com/recaptcha/api/challenge?k=<?=$recaptcha->getPublicKey();?>"></script> <noscript> <iframe src="http://www.google.com/recaptcha/api/noscript?k=<?=$recaptcha->getPublicKey();?>" height="300" width="500" frameborder="0"></iframe><br> <textarea name="recaptcha_challenge_field" rows="3" cols="40"></textarea> <input type="hidden" name="recaptcha_response_field" value="manual_challenge"> </noscript> <button type="submit">Submit</button> </form>
- Server side :
use Neutron\ReCaptcha\ReCaptcha; $recaptcha = ReCaptcha::create($publicKey, $privateKey); $response = $recaptcha->checkAnswer($_SERVER['REMOTE_ADDR'], $_POST['recaptcha_challenge_field'], $_POST['recaptcha_response_field']); if ($response->isValid()) { echo "YEAH !"; } else { echo "Too bad dude :("; }
Bind Symfony Request
A shortcut exists to bind a Symfony Request to ReCaptcha :
use Neutron\ReCaptcha\ReCaptcha; use Symfony\Component\HttpFoundation\Request; $recaptcha = ReCaptcha::create($publicKey, $privateKey); $response = $recaptcha->bind(Request::createFromGlobals()); if ($response->isValid()) { echo "YEAH !"; } else { echo "Too bad dude :( " . $response->getError(); }
