Title: [MOD] reCAPTCHA for e-mail address (...no spam anylonger)
Post by: Sebas Bonito on July 10, 2009, 02:07:11 PM

This tiny snippet keeps your users from spam regarding to your e-mail address in the profile.
With reCaptcha the new e-mail address appears like B...@rainbow.net instead of the whole Beautiful@rainbow.net.
You need to type 2 words to get the whole e-mail address.

(http://wiki.recaptcha.net/images/b/be/Rcptacleanxk9.png)


Step 1. Register at reCAPTCHA (http://recaptcha.net/). It's free and btw a nice project (http://recaptcha.net/learnmore.html).

Step 2. Click on "My Account" and then on "e-mail protection" to receive the api-keys (http://mailhide.recaptcha.net/apikey).
(You'll need the Public Key and the Private Key later)

Step 3. Download reCAPTCHA Library (http://code.google.com/p/recaptcha/downloads/list?q=label:phplib-Latest) and copy the recaptchalib.php to the includes-directory

Step 4.1 Open templates/.../member_profile.html
Search for:

Code: [Select]

<td class="row2">{if user_email}<a href="{user_mailform_link}">{user_email_save}</a>{endif user_email}</td>Replace it with:

Code: [Select]

<td class="row2">{if user_email}
<?
require_once ("../../includes/recaptchalib.php");
$mailhide_pubkey = 'PublicKey';
$mailhide_privkey = 'PrivateKey';
echo recaptcha_mailhide_html ($mailhide_pubkey,$mailhide_privkey,"{user_email_save}");
?>
{endif user_email}</td>And of course change PublicKey and PrivateKey (which you've already got from point 2) to your keys.

Step 4.2 Localisation (like the germany version)

Add (somewhere in the template):

Code: [Select]

<script>
var RecaptchaOptions = {
   lang : 'de'
};
</script>Change de to your language: English=en, Dutch=nl, French=fr, Portuguese=pt, Russian=ru, Spanish=es, Turkish=tr


Step 5. Also be sure... that templates are allowed to execute PHP code:

Open includes/constants.php and search for...

Code: [Select]

define('EXEC_PHP_CODE', 1);If this is "0" change it to "1".


Step 6. This optional step allows you to change the way, how the crypted e-mail address appears (normally e.g. B...@rainbow.net). To change it to "e-mail address":

open includes/recaptchalib.php and search for:

Code: [Select]

return htmlentities($emailparts[0]) . "<a href='" . htmlentities ($url) .
"' onclick=\"window.open('" . htmlentities ($url) . "', '', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=500,height=300'); return false;\" title=\"Reveal this e-mail address\">...</a>@" . htmlentities ($emailparts [1]);Replace it with:

Code: [Select]

return "<a href='" . htmlentities ($url) . "' onclick=\"window.open('" . htmlentities ($url) . "', '', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=500,height=300'); return false;\" title=\"Reveal this e-mail address\">e-mail address</a>";

That's all... You can do this, whereever an e-mail address appears:

Code: [Select]

<?
require_once ("../../includes/recaptchalib.php");
$mailhide_pubkey = 'PublicKey';
$mailhide_privkey = 'PrivateKey';
echo recaptcha_mailhide_html ($mailhide_pubkey,$mailhide_privkey,"{user_email_save}");
?>Only be sure to have
- the right path for the recaptchalib.php
- the right keys, and
- the right variable (in this case {user_email_save})


And by the way: Take also a look to the new reCaptcha-Mod for your site. It's a nice alternative to the existing Captcha (for register, comments, uploads and postcards):

Could you pls report these errors? Additional: How about the server-error-log?
