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.phpcreated by Composer. For example,

require('/path/to/recaptcha/autoload.php'); $recaptcha = new \ReCaptcha\ReCaptcha($secret); // etc.

Usage

First, register keys for your site at https:///recaptcha/admin

When your app receives a form submission containing the g-recaptcha-response field, you can verify it using:

<?php $recaptcha = new \ReCaptcha\ReCaptcha($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
