Very *effective* antispam trick on blogs

21 Oct

Most of bloggers have a problem with spam. Of course, there is Akismet, but sometimes Akismet is not good enough because he doesn’t catch all spam messages. So, with this in mind, i wanted only to get rid of all automated messages.

So, look what i did:

First of all, i go with „robots fills ALL fields with something” in my mind. I’ve added only TWO lines of code: one in comments.php from your theme folder and one in wp-comments-post.php from your root folder.

Ok, how you do it?

First of all you need a ftp client and a text editor. E-texteditor is 2 in 1 so you can download a trial version for doing this. Ofcourse, you can use the old and ugly notepad (or whatever your OS has default).

Open comments.php (which is in your wp-content/themes/your_theme_name folder) then find this line:

<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="commentform">

Some things can vary (like ID of the form), but 90% in cases you won’t need to look for something else ;)

Just AFTER this line you add:

<p style="position:absolute; left:-9999px;">Don't fill this! <input type="text" name="name2" /></p>

We put a form here and hide it. I didn’t use display:none because i wanted to be sure that field will be showed up, even is on the left side of the screen (you should actually turn you head to left to see it :P ) So the bot will actually SEE that form and will fill. Normal user won’t.

Save and upload (or just save if you work directly on ftp) then open wp-comments-post.php from your root folder. Just after the

<?php
/**
 * Handles Comment Post to WordPress and prevents duplicate comment posting.
 *
 * @package WordPress
 */

beginning part, just add this:

if( $_POST['name2']!= ''){
	die('Spammer!');
}

Save and upload.

Next you need to… Hmm… You don’t need to do anything else ! Now empty your Akismet queue and wait to see if you get any other spam messages ;)

Note that is possible to not catch ALL spams, but those are automated you won’t get it anymore :) Also, when you upgrade wordpress make sure you make those changes again. And finally, BACK UP FIRST!
