Help with reCAPTCHA >>>>

hello please can you do it for 1.3?

Sirena - no problem! Glad you found em' handy!

Hey, Fantasma - sorry it's taken me so long to get back to you!
I haven't had the chance to test this yet (I might get the chance later tonight, but if I don't, just let me know if it doesn't work and I'll look into it), but I think this should work:

1. If you haven't already done it, sign up for reCAPTCHA, and download the reCAPTCHA PHP Library at: http://recaptcha.net/

2. Again, if you haven't already done so, extract recaptchalib.php from the PHP Library into your punBB root directory.

3b. Find (should be around line 28):

if (!defined('FORUM_ROOT'))
    define('FORUM_ROOT', './');
require FORUM_ROOT.'include/common.php';

BEFORE (not after) it, add:

require_once('recaptchalib.php');
$publickey = "youpublickey";
$privatekey = "yourprivatekey";

(Obviously, replace yourpublickey and yourprivatekey with your public and private reCAPTCHA keys.)

3c. Find (should be around line 158):

if ($forum_config['p_force_guest_email'] == '1' || $email != '')
{
    require FORUM_ROOT.'include/email.php';
    if (!is_valid_email($email))
        $errors[] = $lang_common['Invalid e-mail'];
}

After it, add:

$resp = recaptcha_check_answer ($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
if (!$resp->is_valid) {
    message("The <b>reCAPTCHA</b> wasn't entered correctly. Go back and try it again.");
}

3d. Find (should be around line 531):

        <fieldset class="frm-set set<?php echo ++$forum_page['set_count'] ?>">
            <legend class="frm-legend"><strong><?php echo $lang_post['Optional legend'] ?></strong></legend>
            <fieldset class="frm-group">
                <legend><span><?php echo $lang_post['Post settings'] ?></span></legend>
                    <?php echo implode("\n\t\t\t\t\t\t", $forum_page['checkboxes'])."\n"; ?>
            </fieldset>
        </fieldset>
<?php

}

($hook = get_hook('po_post_optional_fieldset')) ? eval($hook) : null;

?>

After it, add:

<?php
if ($pun_user['is_guest'])
{
?>
<div class="inform">
<fieldset>
<legend>Are you human?</legend>
<?php echo recaptcha_get_html($publickey, $error); ?>
</fieldset>
</div>
<?php
}
?>

4. Save, upload, and you're done!

Again - this will only make the captcha apply to guests, not registered members - and again, I haven't tested it yet. If I do get the chance to test it, I'll post/make an edit later tonight to say whether or not it worked. I'm pretty sure it will, though, as the code is pretty much the same.

Yes, this uses reCAPTCHA for posting - using this method, if you are a guest, and you want to post a topic/reply, you'll see a reCAPTCHA box on the posting page, which you'll need to pass to post. You can see an example at: http://www.alternative-internet.com/for … hp?tid=129

Since this method only applies to guest posts (i.e. regular users can post as they normally would - no captcha required), if you don't allow guests to post, then this method doesn't do anything.

Setting up reCAPTCHA for registrations is a very similar process - the method I've described here for applying it to posts is somewhat based of a 36invisible blog post on how to implement reCATPCHA for registrations in 1.2.15. (As far as I know, applying it to 1.2.19 shouldn't be any different.)

You can find the post at: http://news.36invisible.com/2007/08/05/ … for-punbb/

Hope that helps!

I am so happy to have reCAPTCHA part of the registration process because I was having 3 or 4 spam registrations from bots everyday...

Thank you!
