Anti-Spam Options - reCAPTCHA v2 Human Verification

(Note: This mod was renamed. The original name was "New reCAPTCHA Human Verification")

What is it?
----------------------------
This mod adds reCAPTCHA v2 as an option in the Human Verification Manager.

Note: The original reCAPTCHA used default keys if you didn't enter your own, so you could leave the key fields blank. This version requires you to have your own keys for your domain. To create them, go to this page (click on the "Get reCAPTCHA" button). It may take a short time after creating the keys before they will work, so if you get "ERROR: Invalid domain for site key", wait a while and try again.

vb3 version is here: https://vborg.vbsupport.ru/showthread.php?t=315964

Installation:
----------------------------
1) Upload the file in the "upload" folder to your server.

2) Import the product XML file from the Product Manager.

3) If you don't already have keys, go to this page and create keys for your domain. (If you already have keys you can get them from that page as well).

4) Go to Settings > Human Verification Manager, select "New reCAPTCHA" for the Verification Library, and click Save.

5) Enter your keys on the options page, and select the light or dark widget as desired (apparently white and black are the only options at this time). You could select "Audio" to default to audio instead of image for the challenge, but the widget seems to have a bug in it at the moment so I recommend leaving it set to "image". Click Save when you're done selecting options.

6) You can check the configuration and do a test by clicking on "Click here to test connection" which appears under the description in the Human Verification Manager.

7) Do a test registration (or other action that requires hv) to test that your keys are entered correctly and everything is working.

8) If you are upgrading from version 0.9, you can remove the file includes/class_humanverify_newrecaptcha.php (the one without the third underscore) from your server.

History:
----------------------------
1.0 (Feb 22, 2015)

• Cached template (required renaming the uploaded file from
  class_humanverify_newrecaptcha.php to class_humanverify_new_recaptcha.php)
• Removed default keys (which didn't work anyway)
• Removed trademark symbols
• Changed execution order of plugins from 5 to 4, to make sure this product
  works with another HV add-on that has a bug.
• If "New reCAPTCHA" is selected when this mod is uninstalled, the hv library
  is switched to 'disabled'.
• Added a test option to print out more information about verification failures

0.9 (Dec 11, 2014)

• Initial Release

EDIT FILE /includes/class_humanverify_new_recaptcha.php

On line 14 replace:

		parent::vB_HumanVerify_Abstract($registry);

I see this in my log:

mod_fcgid: stderr: PHP Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; vB_HumanVerify_NewRecaptcha has a deprecated constructor in /httpdocs/includes/class_humanverify_newrecaptcha.php on line 8, referer: /register.php?

I know it is only a warning but a fix would be nice..

Line 8 is:
class vB_HumanVerify_NewRecaptcha extends vB_HumanVerify_Abstract

Is that after you apply the fix above?

[RichieBoy67]

I applied that fix years ago.. been awhile.

[djbaxter]

Within the class defined at line 8

class vB_HumanVerify_New_Recaptcha extends vB_HumanVerify_Abstract

is this at line 12

	function vB_HumanVerify_New_Recaptcha(&$registry)

Could that be the referenced conflict?

[RichieBoy67]

Thanks,

Line 8 is class vB_HumanVerify_NewRecaptcha extends vB_HumanVerify_Abstract

This is line 12: parent::__construct($registry);

[djbaxter]

This is the first 16 lines of my version - does this not match your version?

PHP Code:

<?php
if (!isset($GLOBALS['vbulletin']->db))
{
    exit;
}
require_once(DIR . '/includes/class_vurl.php');

class vB_HumanVerify_New_Recaptcha extends vB_HumanVerify_Abstract
{
    public static $verify_url = 'https://www.google.com/recaptcha/api/siteverify';
    
    function vB_HumanVerify_New_Recaptcha(&$registry)
    {
//        parent::vB_HumanVerify_Abstract($registry);
        parent::__construct($registry);
    }

Complete file is attached.
