[ADDON] ReCAPTCHA

I've written an reCaptcha addon for Elkarte using the v2 Google reCaptcha service which uses a checkbox instead of verification text for most uses it deems to be likely human.

Grab the addon: https://github.com/Xydre/elkarte-recaptcha

Got a few errors for each person that tries to register:

Here is my reCaptcha.class.php file, too.

I would change the block:
Code: [Select]
	
	public function doTest()
	{
		$this->_recaptcha = new ReCaptcha($this->_secret_key);

		if ($_POST["g-recaptcha-response"]) {
			$resp = $this->_recaptcha->verifyResponse (
				$_SERVER["REMOTE_ADDR"],
				$_POST["g-recaptcha-response"]
			);
		}

		if (!$resp->success)
			return 'wrong_verification_code';

		return true;
	}

to:
Code: [Select]
	public function doTest()
	{
		$this->_recaptcha = new ReCaptcha($this->_secret_key);

		if ($_POST["g-recaptcha-response"]) {
			$resp = $this->_recaptcha->verifyResponse (
				$_SERVER["REMOTE_ADDR"],
				$_POST["g-recaptcha-response"]
			);
			if (!$resp->success)
				return 'wrong_verification_code';
		}
		else
			return 'wrong_verification_code';

		return true;
	}

Still getting 2 errors for line 58:

Code: [Select]
if ($_POST["g-recaptcha-response"]) {

1 error per person, so we almost there.  ;D

I guess:
Code: [Select]
if (!empty($_POST["g-recaptcha-response"])) {
:D

That did the trick, it seems. At least, for test account I just did. :)

A bump!

I made a few updates to this package and put it on the addon site http://addons.elkarte.net/security/reCaptcha.html

This update allows you to specify the language code (from google) and uses ElkArtes functions for posting the form data back to Google, and loads as a deferred/async script.

Hi Spuds -
Just installed the package. On the page you referenced, there is a screenshot showing where to enable/disable this package and to add the key pair .  However, I don't see a way to get to this screen from the install.  How do you get to that screen?

It should be under 
Admin -> Security and Moderation -> Anti Spam 
on that screen, at the bottom is where it should show up ... if not then I made a mistake when I put the package together !
