Description
reCAPTCHA is a free CAPTCHA service that protect websites from spam and abuse. This is Google authored code that provides plugins for third-party integration with reCAPTCHA.
Manual installation
If you wish to install the library manually (i.e. without Composer), an autoloader is provided assrc/autoload.php
. You can require it in your script instead of the usual vendor/autoload.php
created by Composer. For example,
require('/path/to/recaptcha/autoload.php'); $recaptcha = new ReCaptchaReCaptcha($secret); // etc.
Usage
First, register keys for your site at https://www.google.com/recaptcha/admin
When your app receives a form submission containing the g-recaptcha-response
field, you can verify it using:
<?php $recaptcha = new ReCaptchaReCaptcha($secret); $resp = $recaptcha->verify($gRecaptchaResponse, $remoteIp); if ($resp->isSuccess()) { // verified! } else { $errors = $resp->getErrorCodes(); }
You can see an end-to-end working example in examples/example-captcha.php
